How to Spot a FAULTY CPU.....? The i7-4770 Dilemma....

[@franzb69]

i also have had experiences where i have a buyer that would replace the parts that i sold him with exact same parts but are defective. so always make sure to have records of serial numbers of the stuff you have to make sure he didn't swap stuff out for defective ones.

[@aboyaser5608]

This is such a scummy thing to do ( I know this is obvious but I needed to say these words out loud)

I once had a 4790k that had some weird issues with low power states (c6/c7), the system would freeze after ~5 mins in idle. Disabling these low power states fixed the problem.

[@gaunterodimm3606]

Some of the c-states can act a little funky on Haswell. I shut off most or some times need to shut off all the c-states with Haswell for overclocking.

[@DuneRunnerEnterprises]

Get the same craptasting thing,the C6 setting,on an AMD cpu'ed board. Disabled it,running fine even now 8)

[@TheCgOrion]

I had that on a CPU (not Haswell), and it was the lower voltage causing the instability. It would run the lower speeds fine if the voltage was manually set. What you did makes perfect sense. It's been tested and the power difference is negligible between letting the clock speed and voltage drop and manually locking both. The current is drawn on load anyway, and the power difference between a small process completing at full speed vs taking longer at a lower power draw is small. It comes down to efficiency at that point. When I saw the numbers on a modern CPU with everything locked vs all of the power savings running, I stopped worrying about it.

[@pedrobastos8132]

Haswell was kind of a wonky generation. I had a 4790k that was an awful overclocker, couldn't barely get to 4.6 GHz and had it running most of the time on stock because it was so unstable, really.

[@-eMpTy-]

@@pedrobastos8132 I'm actually still using a haswell CPU, an 4770k that I picked up rather cheap in a bundle. I overclocked it to 4.5GHz/1.32v and it runs perfect in combination with my 1060. Temps are also good using an Thermalright Macho Rev. B, the only issue is the core to core thermal difference, core0 to core3 are under load 7-10°C apart. I might delid it soon but since the temps in general are fine (70°C max at non-avx load) there isn't really a need for that.

[@adamreid5901]

I had a faulty CPU in my 2016 Touch bar Macbook (i7 6820HQ) and it was incredibly hard to get Apple to accept that there was a problem with the machine, their own internal stress tests couldn't replicate the problem, so even if say rendering in premiere would cause a crash report from the kernel saying the CPU was bad, or I'd have kernel panics they wouldn't accept a warranty claim because it'd pass their diagnostic.

Usually it's the Memory 9 out of 10 times

[@gaunterodimm3606]

Memory, bent pin or dust in socket, blown PCI lanes, bad sata, fried chipset. It is rarely the CPU though i have had it happen but your right it's usually memory.

[@aoelp]

@Adam W I already have seen more faulty or even dead CPUs (i5 6600k, i5 6400, FX 8320) than any of these problems though. A buddy of mine bought an i5 6600k from Mindfactory (biggest German/European e-tailer for pc parts) and left it at stock (MSI Z170-A) and it died just months later, meaning it would crash @stock constantly, had the Windows boot screen watermarked in UEFI - it was weird all around - and ran fine lowest clock of @2.4 GHz in Prime95 for just three minutes until BSOD. Swapped memory, board and PSU and the problems persisted until I swapped the CPU with an RMA sample, no problems since then... I also built a PC for someone on a budget with an i5 6400 from eBay from a commercial seller with >5000 feedback (99.9% positive) as "known working, even optics checked" and it came bent. I know Skylake had some problems with bending, but never had that problem myself until then (have an i5 6400 in secondary PC @4.7 GHz with DDR4 @>3800 MHz xD), so we thought the bluescreens (somewhat counteracted by adjusting system agent voltage and similar) and program crashes would simply be caused by the (DDR3 bclk oc Z170) Gigabyte motherboard which was in for RMA already. Since we also tested and another chip (almost known good Skylake ES "QH8F" - guess who inspired me) also was unstable, this was pronounced. Turned out the motherboard was bad and was repaired just luckily a few days before warranty expiration from September 2016. After repair strangely everything worked fine only with memory in channel B, with any out of piles of memory in channel A and/or B the PC did not boot. Turns out the chip was damaged due to the bent. Since I life in Germany I thought: "No problem I have two years warranty by law with six months of "burden of proof reversal" (direct translation of the law), so I just need to tell the seller. The seller declined because I did not return the item within two weeks after purchase. Excuse me, someone does not know law here. After many fruitless mails I let the case rest until I met a lawyer that would take my case for free (only would take a cut of the fine), so I got 60€/71€ back from my purchase, after the seller received a legal letter. The chip however still works fine in single channel even @4.3 GHz (4.4 GHz was unstable @1.38V so we stopped there) with just two slots and it was almost free. :D Also know a guy whose FX 8350 was dying (random bluescreens, lacks and program crashes or complete boot failures). He against my advice did buy a new motherboard and had the same problems (PSU, HDD and RAM already known good and replaced). He eventually got fed up and sold the chip as non-working alongside the other used parts on eBay - so I borrowed him my aforementioned spare PC with overclocked i5 6400 and he (apart from his new motherboard, the CPU and RAM) still uses the same parts and only had one bluescreen since he hot-plugged a HDD and no further problems. And since he is no stupid fanboy, he is considering saving up for a Ryzen build this year because of the value and new components. He really did not want to switch to a random Intel platform just to keep his DDR3, which I second. Furthermore I have some CPUs with bent pins, but that is another story, since these CPUs are technically repairable unlike with internal damage which is irreversible. So yeah, CPUs get faulty or die more often than many may think, source: my experience: Built and mantained about ten PCs 1x memory (very cheap stuff) 2x bent pin (once did it myself, repaired all) 0x dust in socket or similar 1x blown PCI lanes 0x bad sata 0x fried chipset, maybe more but idk for sure, could be 0 to three times Meaning all known to me apart from mostly irrelevant or fixable cases of system failure mentioned in the list are less for me than dead or failing CPUs, so really not that uncommon sadly. Still way less likely than RAM, other motherboard component, HDD or PSU failures though. Only unfixable and stability affecting one was RAM in one case for me. Also never had any fan die on me ever apart from two very cheap ones which died within the first second of use (one the same fan header any of my other fans worked fine and they are similar CPU fans).

[@aoelp]

@desertrat810 That all makes sense, since I think the most failing CPUs are either old hot Intels like Pentium 3/4 or similar AMDs like Sempron, Duron or FX and newly those flashy new Intel chips. Hell I've never seen that many dead CPUs before Intel 's now infamous 14nm node and I don't think Intel's "rise" in popularity or dumb and careless customers are to blame - tech gets more fragile nowadays and who can repair CPUs that small? I think running them with bad components can kill them, but I admit I put an i5 2500k into a bent socket for testing and the socket was shorted (VCC to GND) so that it basically unsoldered a gold contact pad from the CPU which I had loose afterwards. The funny thing is I send the board to a person repairing it for 40 bucks and put the CPU back in and everything worked fine. So, I guess moral of the story: Don't do that even if it worked out for me. xD Really any of the CPUs I describe here are not very old just 7 months for the 6600k, at most since Skylake released (then 2.5 years ago) for the i5 6400 and I think 8 years for the 8320. Especially the latter ones die like flies, but who cares FX was long dead anyway I recon and any real gamer can attest that. So to anyone doubting: I have many CPUs and none of that that died/are dying were run overclocked at any point by myself, so that is ruled out as a factor. In contrary most of the other CPUs I have were tortured to the brink and many were in now dead motherboards and still work just fine.

[@C-S-J]

I had a Cyrix 5x86-100. Cyrix chips were notoriously hot CPU's, but I found most of their problems stemmed from software bugs and incompatibilities. I started into overclocking with the Celeron 300a on an ABIT BH6 motherboard, it was a very simple overclock of the FSB from 66MHz to 100MHz and CPU clock speed increase of 50%. The Celeron 300a was actually a better CPU for gaming more often than not vs. the much more expensive Pentium 450, because of faster L2 cache even though it had 1/4 the amount. Overclocking back then was physical dip switches and jumpers on the motherboard, not fancy BIOS settings.

I have a 4770 and I'm now wondering if my CPU has gone bad. Temps are fine, usually 30's when idle, 50-60c when gaming, but 2 times in the last 3 months my PC has done a slow freeze and lock up. When this happened, I was playing a game on one screen with Chrome open on the other with task manager and Afterburner background. One time the game froze 1st, then Chrome. Other time it was reversed. After those 2 froze, the task bar would slowly become unresponsive. Afterburner freezes. Any other programs open would also slowly freeze. Task manager is always the last to freeze, but clicking End Task on frozen programs does nothing. Then it's frozen too. After about 5min or so, the mouse and keyboard stop responding. Only 3 things I haven't swapped out is CPU, main SSD and MB.

[@markteeee]

Another great video Bryan. It's a very rare occurrence, nearly always cpu cooler ( dust/ dried thermal paste etc ) related but worth bearing in mind after checking the more common faults.

[@forestmanzpedia]

Different story, but something was wrong with the PC of my mum. It kept crashing and never turned on when we hit the power button. We sended it five times to the merchant who sold us the pc. Every time he checked it, he said it was fine but never fixed anything. My mother was one of those people who threw everything away if something didnt work and would buy a new one, so I suspected the merchant never looked inside of the pc, which everyone should do, if a customer tells you something is wrong with the pc. We returned the pc again and he became salty because he had to check the pc again. Then I told him "Then you clearly never looked inside! Seriously! You cant do small tests and say everything works well." It was clear in his tests the pc was running fine, yet he never looked inside, simply because all what he did was to check if the pc is turning on. After telling him my mind, he did check the components. It turned out the PSU had a faulty, he replaced it and apologized for the mess. I asked him what kind of a technician he was and we didnt pay the last repair bills for all this mess. To that time I was 14 years old and didnt knew much about pcs.

[@paulf1071]

My 2 year old workstation, which is still under warranty, has had the PSU replaced, and then the Motherboard. It's still failing for the original fail, four beeps (power error). Nothing on the screen. Problem not the SSD, any other drive or the GPU pulling it down. Same beeps with only one stick of Memory installed, and CMOS reset button made no difference. It must be the XEON E5 CPU.... what else could it be...??? This offering from Intel is a server-grade processor. How often do these things fail?

[@WrexBF]

I recently picked up a Xeon E3 1270 V2 for $60 on eBay and it performs like a $100 i7 2600 if not slightly faster. I was worried that I would run into microcode compatibility issues cause HP does not list Xeons as compatible with their Q77 chipset boards, but the CPU worked without a single problem.👌

[@SheepInACart]

I'm not sure why, but despite the exact same architecture and only 100mhz speed difference I've never come across a Haswell xeon that's had the same issues with temperature, even spite of the fact many where used in much higher duty cycle loads with smaller cases/coolers than there consumer breathern. Could it have something to do with crystallization of the TIM with heat cycles rather than actual drying, or perhaps that these CPU's never saw attempts at being overclocked? Or may there have been a difference in the binning/selection criteria? Either way, they are a pretty cheap/widely available part still, so if your buying used and your not getting a K skew, I'd compare prices.

[@techyescity]

You are onto something there, I noticed with some of the mining experiments I did back over a year ago, that some GPUs would be fine* to just keep on running, but take them down for a week then try booting them back up and you would have to change the thermal paste. Something to do with cycling from hot to cold?

[@cheesetoucher5941]

umm I'm gonna say voltage is the answer? my E3-1246 v3 needs only 0.89v to maintain 3.5ghz and 1.01 for 3.9ghz "turbo" speed, the 4770 I got rid of needed 1.19v at 3.5ghz and 1.22 at 3.9ghz... both kinda won the silicone lottery, and tested on the same boards. the 4770 needed more volts, hence ran hotter than the Xeon at the same speed...

[@C-S-J]

Haswell E (HEDT) and Haswell EP (Xeon) use solder TIM not thermal paste.

[@SheepInACart]

@@C-S-J True, however the Xeon E3-12xxv3 of the LGA1150 socket is in fact thermal paste, not solder, and are the directly comparable parts to the i7 4770 of the video referenced in the video... and yet doesn't seem to face the same age related overheating or instability as the consumer i5 and i7 chips. This is why I'm speculating about either binning differences of the core itself or effects the different use cases have on the longevity of the paste. And the conventional logic that more use and hotter running would correlate to drier paste and higher temperatures later in life doesn't seem to hold up with my experiences on the platform.

[@droptoasterintub297]

Xeon's are better binned parts for Enterprise systems that need power efficiency and stability. So of course it makes sense when a Xeon counterpart from the same architecture runs cooler and with less voltage than their desktop counterparts. But yes, Haswell was a very hot architecture in general (even hotter than Ivy Bridge) compared to Sandy Bridge, and most overclockers were better off with the 2600K due to it's best performance without the hot temperatures since it was soldered. That may be why a lot of people never upgraded from their 2600K until Coffee Lake came around. This was fixed when Skylake came out with the 6700 being quite cool when you're not bumping up the voltage, just to be undone once the 7700K came out due to the high clock speeds and obviously the poor choice from Intel to use TIM on enthusiast parts. Ivy Bridge and Haswell overclocking ARE NOT the same procedure when compared to Sandy Bridge. The 22nm Tri-Gate transistors are much more sensitive to voltage than the 32nm transistors we saw with Sandy Bridge. This can prove to be a pain when overclocking since you may need to bump the voltage to reach higher clockspeeds, but that may cause the heat to ramp up with it. And we also know that voltage does cause a linear increase in heat either. As for thermal cycling, that's a lot worse on a CPU and GPU than if you ran it constantly at the same temperature. Large temperature spikes can prove detrimental to hardware. It's why mining GPUs are usually actually in better condition than a GPU used for gaming because a GPU used for gaming will be thermal cycled A LOT between hot and cold temps. And there's miners that actually ramp the fans up and undervolt their GPUs also to keep low temps. Thermal cycling can cause PCBs to warp over time and solder to crack. In fact, the Xbox 360 had this issue where it would get very hot under load, cool off when not in use, and over time this caused the solder that held the GPU in the socket to crack and cause the GPU to stop working, and thus the red ring of death would occur.

[@bobxdark370]

@13:57, we can clearly see a "gap" in the glue on the PCB. May that be contributing to the thermal paste actually drying off ? i.e. the humidity just escaping ? If so, what would be a good test we could come up with, without delidding, to test the glue between heat spreader and PCB ?

[@DrSalvador555]

Glad you mentioned it could be heat instead of something else TYC, I had an old FX 6100 and that thing would get dusty, so much so that after a couple months without cleaning that it would simply turn the whole system off without an error, just a black screen and everything powers off. It's important to maintain your system, and if your previously working CPU suddenly starts crashing, check those temps! General rule is:

The office space my mom works at has been using HP computers with i7 4770s for over 5 years I think. It was supposed to be amazing, too of the line performance, but I’ve nicknamed those computers the “Disappointments”. If there is a dilemma with 4770s, that would partially explain why they all suck. They also have HP’s horrible motherboards, no cable management, tiny tiny AIO cooler, and mismatched ram (an 8gig stick with a 2gig stick). So glad they are getting replacements and I’m more glad that I’m being commissioned to build them.

I have changed the power supply, tested both the rams, added a new cpu cooler with new grease, tested it on unraid still turns off, remove all hdds and tested it still turns off, removed most usb plugs, changed grease on gfx card which made it 12c cooler understress. Ram test just turned off was at 92%. Temps are generally really good on the cpu. Below 37 max 50 to 60. Will try Prime95 tomorrow.

hi any ideea why sometimes i press power button on my pc and everything start spinning fans and psu but is not booting , then i press the power button turn off psu from back button wait 1 min and press power button again pc start booting and working as normal . ive changed my psu 80 gold+,my ram,cpu, hard disk,gpu but not the motherboard some one experienced this in the past?

[@imampula3154]

I bought a Cpu and mobo 8 months ago. It didn't started quite well, random shut down, freeze etc. But recently when i start computer it just opens but all the apps disappeared, basically it's gone. When opened the intel i-3 10gen processor just showing burn mark really unfortunate, intel won't relplace it because of burn mark...

[@phillipnguyen5888]

My computer turns black and all the fans go on high speed. Any suggestion whats going on? It's been happening couple times a day now

[@CurtisB28]

I've got a persistent crash problem with no error message (black screen) and then it reboots itself. I currently have a computer from this era (i7 4790k) however I don't believe my problem lies with my cpu at all, I had an i5 4460 prior to this, I also have a gtx 970 which I believe is the fault, the black screens only occur in games, more often than not in older games, like MW2 it'll crash 95% of the time over 30-60 min usage, newer titles may take a little longer to crash, temperatures are fine (core wise) on both CPU and GPU, I've tried overvolting my GPU at stock clocks, to no avail however, it still black screens. CPU I running at 4.6ghz @1.22v stable. Any help or advice would be appreciated I've had this problem since I bought it in 2015 Specs; MSI Z87M GAMING, i7 4790k, GTX 970, 16gb HyperX Savage RAM 2400mhz, 620w Seasonic PSU.

[@auridiamondiferous]

I have an i7-920. Sometimes in summer it started to have weird crashes. Turned out it was overheating to 99°C. I completely de-dusted everything inside the computer and it has been running smoothly since that. It is easy to overlook heating problem possibilities until you face one first time.

[@Koeras16]

A computer should be cleaned and thermal paste changed about every third year I would say. Depends of course on the environment. There is software like HWinfo64 that can help you keep track of your computer and thermals. Thermal Paste always gets hard with time. That and dust would probably be one of the two major reasons why laptops tend to die rather soon (3-6 years).

[@murraystechtime8530]

Great video, lots of information. I've fixed lots of computer processors, but that was when they were still made from desecrate components. I had to troubleshoot and repair them to component level, replacing capacitors or resistors or IC's or transistors or diodes. Now that was before micro processors like today's, these were on one to six circuit board cards connected by via a BUS. A lot different than what you are doing, but at that time it was the in thing to do, lol...

[@ishrakhaider9654]

I have a cpu which restarts again and again. I replaced every single part. When I put new cpu it worked. Is there any thing I can do with the cpu that causes the computer restarting again and again? Should I sell It? or recycle?

[@goodwillhart]

I had that once, where I replaced every single component of a computer. In the end I even replaced the case. It would run for a week, even in my office, then just hang. Of course the customer just assumed I was a lousy computer technician. It was very hard to convince them that this was an incredibly unusual situation.

[@Nixs1]

I think i have a faulty 8086k. I had bsod's randomly, even under windows install sometimes.. sometimes it would let me install it other times it would just freeze or bsod. I noticed a bent pin on my motherboard and replaced it. Although it had seemed like the cpu contact side had some darker spots, or miscolour. Mind you i had a h150 360mm radiator on the cpu and it never got over 50 under load, so i cant see how that would burn it. But after i replaced the motherboard i still had the same problems with bsod. Also tried with different ram and ssd's. Could the bent pin have damaged the cpu somehow?

[@gnzllr]

12v, 5v, and 3.3v are way too high, PSU has some issues...

[@Ghozer]

Nah, won't make any difference.

[@ValkyrieStarTV]

They're well within tollerances. The ATX spec gives a +/- 5% limit. 12.6v max, 5.25v max, 3.465v max.

[@mrlithium69]

Theres 10% wiggle room on ATX voltage specs. And only 12v is relevant here, which further gets converted both in the motherboard VRMs and in this case on the CPU FIVR.

[@TheError404]

And all the critical parts of the computer generate the required voltages locally (CPU, GPU, memory etc) so even 10% higher voltages won't hurt a bit

[@tyclemons161]

I got a question to anyone who can answer. I purchased a i7 7700k 1 year ago and since day one I would have to add voltage or overclock the cpu from having it not blue screen on windows. If i run it stock in 10mins it will blue screen. Do you know why?

[@georgecheung3853]

So... I know this is an old video and the chances of anyone seeing this is quite low I bent the CPU and I chucked it back into the computer and it boots. However, it failed the prime95 blend and Smallfft test. Froze up within an hour. Currently I am trying Smallest FFT. Does it mean my CPU is failing and I should get a new one?

[@ReganMarcelis]

Bryan, my 2679 v4 was pricey, how do I know if its blown or bios not supported on two boards as no board says they support it?

[@Jp-ue8xz]

THANKS! you saved me from throwing away my 7700.... I bought this second(?) hand cpu for an old mb and it worked fine for a couple of days, even benchmarks all below 85C until it started freezing dead before boot... it just froze either before post, during post, or after a few seconds at the bios screen when I managed to hit F2 in time... I swapped it for an 7100 i have laying around to modify the config to lower the ratio, fix the cpu core voltage at 1.125, and disable turbo-boost... then back to the 7700 and it FKIN WORKED :D... It's running hotter than usual but at least it's not an expensive paper weight now :D

[@robinsoneveonline]

Hi, I'm researching my own faulty cpu after having to fix many other system issues first. My Ryzen 3700X has a worker fail on the start of running a Prime95 test. The manufacturer suggests I change all my hardware to test and seek the help of friends etc to help complete my tests, well this simply is not an option, my hardware has already been changed many times for other system faults. Time and hardware cost are getting very high now. If the manufacturer cannot advise me on a simpler test option without the need for a lot of hardware swap outs then I have got a problem I cannot diagnose easily. My cpu is still under warranty and the retailer has been very good with other hardware returns, but I feel like the manufacturer should step in on this one and help me out more. Yes I may be able to under volt to fix the issue, but I feel this cpu should be rock solid on default bios settings and that is what I have paid for. If you have any input on this that would be great to hear.

[@BOLOYOO]

My 6600k randomly freezes the entire computer (it had nothing to do with OC or C-States, if it didn't freeze PC, it would run any test). I have been looking for a problem for a long time, blaming RAM, motherboard, power supply and disks. Until now, I had no idea that the CPU has more states than two "works" or "doesn't work". Well, man learns his whole life;)

[@christopherjames9843]

"ex client" lol! Bryan never pulls any punches. Dude is always honest.

[@bonnome2]

I had the same problems with an Engineering sample cpu, it is running mostly fine now without changing much of the settings. I did change out the motherboard battery and that increased the booting stability a bit.

[@V3racious3]

Cool video. It is a two for one. You also show how to destroy memory by installing it while power is running through the motherboard as well as handling the memory stick on the memory chips rather than the edges of the DIMM as shown in this video.

[@lolisamurai]

it seems that haswell had an unusually high failure rate. when I got my new 4790k a few years ago it fried a few months later and would start bootloping for 30+ mins before booting successfully. it turns out my motherboard at stock settings was overvolting it like crazy (something like 1.4v). not sure if this was just the cpu being faulty and not holding boost clock at normal voltages or if the motherboard defaults were just broken. good thing I ended up getting a free replacement

[@alexmihai22]

I had a i7 4770 that I delidded, I didn't seal the IHS to the CPU little board. I used Arctic MX4 both between CPU die and IHS and between IHS and cooler. It worked fine for about one year and a half.. until last week when it simply refused to boot showing nothing on the screen. I took it out, I re-placed it in socket, and now it works again. Before delidding I had 70 Celsius in idle.

A problem I am having is that I updated my CPU from I i5 not that good of a processor to a i7 7700k and didn't see much of a difference in fps as much as I would thought would my gpu is a GTX 2060 super also to note my friend got the same CPU and a 1080 that is not as good as my GTX and get so much more fps in games please help

[@hartsickdisciple]

I like this video, and conclusion you came to. I've had 2 3770k's overheat severely with even minor overclocking/over-volting. I ended up de-lidding the second one, applying liquid metal, and it now stays cool and stable at 4.7 ghz. I think de-lidding is almost mandatory at this point with these 3rd and 4th gen chips, if you want a decent, stable OC.

1 year ago i changed my motherboard (they) because my cpu i7 4790k it will get hot when i run games my question is after watching this video do you thing they knew my motherboard was fine they delid the cpu and made me buy a new motherboard?

[@m8x425]

I've been building and repairing computers since 2008 and I've only come across 1 bad CPU, which was a dying Core i7-2700k. It needed extra voltage to boot into the system without crashing. One of the contacts (Lands) on the bottom of the 2700k was black, not gold. On some ebay listings, I've seen "Parts Only" processors that were missing capacitors on the bottom of the CPU. So it does pay to visually inspect the CPU. I didn't need to run the P95 method because I had a working 2600k. In fact, I've used Prime95 Blend to diagnose DRAM problems. Sometimes with the DRAM and CPU stability problems, a thread on the Prime95 test will stop running. With the memory I can swap and add sticks in order to find the bad stick. Another guy I know scrimped and saved to his funds to get a Core i7-6700k, which had a problem with one of the memory channels not working. This resulted in 2 of the memory slots not working. At least he was upgrading from a Core i5-6500 which recognized all 4 sticks, so his problem was easy to diagnose. He tried raising the VCCIO, VCCSA, and DRAM voltages but this didn't help him. He even tried reseating his cooler and everything was good.........no bent pins. There was another time I put a mono-block on my system, and the uneven mounting pressure caused one of the DRAM channels to quit working properly. All I did here was I reseated the mono-block, and everything was fine after that. So it pays to make sure the cooler was mounted properly. These days when I delid my processors, I use liquid electrical tape on the contacts that are next to the die. This will keep the liquid metal compound from shorting those contacts and killing the CPU. Some people like using clear fingernail polish here, but I like using the liquid electrical tape better.

[@jacks6910]

All my io and gpu output keeps turning off randomly, stress tests and games don’t seem to make it anymore likely to happen. Replaced mobo, ram, gpu, no change. Sometimes it won’t boot until I change out random parts after the crash, doesn’t seem to matter what part as long as something changes. Windows event viewer shows nothing.

[@JuxZeil]

Don't know if anyone's pointed out but, next delid, use some nail varnish on the tiny resistors next to the die. The liquid metal can migrate and short them, which is not good. Other than that, great little 'how to' Brian. [thumbsup]

There is something perversely enjoyable about watching someone track down what is causing a computer issues, jay did a few of these videos a few months ago but sadly stopped.

[@SwaggD0e]

Picked up a 4790k and I noticed on idle i couldn't get a good read on still idles temps so I bought a h1ooi pro to maybe help negate it (had a 212 evo) even bought some mx4 paste to see if that would help. temps are still the same, low mid high 30's and then jump to 40's and 50's for a split sec and back down to around 30's and 40's. I do have it OC'd to 4.7 mostly stable but when ever I do stress test using AIDA 64, after a few mins( varies) pc would fully freeze and I've been trying to figure out why, Im guessing it could be the paste under the IHS so after watching this video I might have to consider deliding just to see if my pc wont freeze during stress testing. Here's hoping that its just the paste on the IHS

Recently I did a build with a 4770K. OC'ed to 4.4GHz on a Corsair H110, it maxed out at 79c during Aida64 (after some minutes). I was pretty sure it's been delidded by previous owner (Sometimes you get pleasant surprises when hustling 2nd hand hardware. :) Another way is to see how quickly the temp rises after the stress test startup. If it instant goes to max temp, is the connection between die and IHS is the limiting factor.

[@BelowAmbient]

I had a CPU that had a bubble in the paste application that actually caused a small fire, after taking the cooler off it has a small little crater where it had been burned...CPU runs fine after repasting but I had to add just a bit more paste to that crater area... Weirdest thing ever

[@dra6o0n]

Can you also get a computer freeze from GPU issues, because at times I wonder if setting certain overclocks to undervolt at a good level and idling, after a few days of letting the PC run it may randomly 'freeze' for no good reason and needs a reset and re-calibrating of the GPU stuff. I don't know if it's actually CPU since I use a generally stable level of clock speed for my Ryzen 1700, like 3.65Ghz.

[@ilhuikar]

My 4790 is on the warm side too, but since it's not giving problems and as you say it's still somewhat expensive, I'm not going to risk delidding. But maybe some day.

I got a dilemma as well. I got a ryzen 2700x , paired with gigabyte aorus ultra gaming x470 and a ocz 650w power supply. When the electricity drops in the house or i turn off the power supply the pc wont start and i get a red led on the motherboard for the cpu and it blinks to ram , if i reset bios settings it turns on. Can it be my power supply? Also gpu from time to time at random loads be it in google chrome or in games the display goes all back and the sound cuts off for a second then the screen turns back on like nothing happened. It takes 1 sec . Any ideas ?

[@giglioflex]

The power supply is definitely most suspect. What do you mean by "when the electricity drops"? Do you mean your house has poor power delivery or during a power surge? Just to note, power surges can damage your PC. If you loose power frequently in your area you need to make sure your PC is behind a quality surge protector. Not the dollar store surge strips. In addition, unless you are willing to spend big money all power strips use sacrificial MOVs that degrade after each power surge. They need to be replaced every few years or earlier if you have many power surges. For those with expensive computers I'd simply recommend spending the money on a power conditioner.

you mean the cpu has quadchannel memorycontroller which drive every rammodule? i do know nothing about apple shit. only the e5-1600VX CPUs which are taken from the mac pros i know. i would change the memorymodules inbetween the slots, look if they are correctly in the slots?? or does there is relay a processor chip on every module to make it as expensive as possible? every time i look at apple mac pro websites i wonder how anyone is willing to pay this absurd high prices. for the design? I can build a pc with the power of a 30000€ mac pro for ~1500€ with used parts from ebay using also xeons but older generations which are unlocked and minimum as fast as the newer ones with reference clocks, if you overclock this unlocked cpus to a similar stable oc in the bios. An e5-1650 wich costs about 65€ is as fast as an e5-1650 v2, v3 with very realistic and stable 4,5 GHz watercooled with an 50€ aio it is as fast as an e5-1650 v4. and 256Gb Ram is quite a lot. ok the v4 supports 768 GB. but i see that you don´t have to overclock an e5-1650 to 4,5 GHZ to make it as fast as the v4. maybe 4,3GHz is enough. for this clock you just have to raise the coremultiplier to 43 in manual settings and put the corevoltage and vt voltage to manual and + below!! but the thing is that the mac os just works if it is emulated because of missing driver signatures . there is allways a little inputlag and this is unacceptable for someone who needs the apple for work. apple wins this game at the end:(
