[@ScottGrammer]

The 3900x was a hot chip, and if not properly cooled I could see the IHS becoming partially unsoldered from one or both of the CCX's. This would make it pretty much impossible to thermally manage from then on.

[@brucepreston3927]

It would be awesome to see him delid it and try it again! It's already damaged so he's not really gonna break it more! lol

[@rangersmith4652]

That could be, but I've got a 3900X that's been running flawlessly in a gaming rig with a Scythe Mugen 2 cooler. The only issue this PC has is when running a particular game with the FPS cap wide open and the display set to 120Hz; the CPU fan surges wildly. I've never been able to sort that one out. But it's non-competitive MMO whose animations look best at 60 FPS, so there's no reason to run it faster.

[@dremy746]

solder melts around 200 degrees Celsius. I don't think any 3900X was getting that hot, no matter how bad the cooling was.

[@testickles8834]

all AMD's are hot chips. I am guessing you ain't old enough to remember the old melting amd chips.

[@ScottGrammer]

@@dremy746 Different solders melt at different temperatures. The solder used in CPU's is not the same as the lead-tin solder used in making electrical connections. The solder used in CPU's is indium solder, which melts at 157 degrees C, and can soften at lower temps.

[@AAjax]

For the ones with dram led... Tech Yes Bryan found he could revive a "dead" 3600 by undervolting in the bios with a good cpu, and then switch to the dead one. It would be interesting if you could make any of yours work by undrvolting or reducing the clocks. [edit] lol, just got to the last one where you did just that. Worth re-checking some of the others similarly.

Great vid and quite helpful- I build a lot of Ryzen based computer systems and this helps with a "heads up" of possible outcomes. I have not yet witnessed these symptoms, but good to have this knowledge.

[@salvatorearbassio3609]

Good vid, love the troubleshooting.

[@capsulate8642]

The 5900x seems similar to a few cases of degraded silicon I've seen. With some time you could probably dial in the voltage/clocks to get it running pretty close to stock. Not perfect but would still work well as a homelab CPU or something.

[@hrayz]

I have an old fx-8370 chip (use it as a test bench and backup media system now). Used to oc to 5.0GHz, but slowly became unstable over the years. Now it'll run fine forever at 4775MHz but not at 4800 or more.

[@TheParandroid]

As others said, the 5900X is "fixable" by disabling Global C-States control in BIOS, which disables core parking feature. My 5950x just did this last week, while it can be fixed by disabling this option, personally i decided to RMA it instead.

[@JeremyHeslop]

Had a 5800 that would always work with pbo off. Probably a cstate issue but I just got a replacement also

[@rohan8611]

Hey Greg, thanks to you & your fix or flop series i was able to fix my 10 year old desktop, so let me share what happened the. Out of the blue the system started Blue screen of deaths different error everytime so i thought maybe the windows was corrupt and tried to fresh install the windows but it wouldn't let me boot via the Pendrive, so i thought maybe the HDD had given up the ghost. Had a spare HDD lying so decided to swap it and sometimes it would just bootloop and sometimes it would just give no output to display so started by disconnecting RAM's to narrow down the problem so guess what 1 of the RAM sticks had gone faulty so tried putting it in the other slot to rule out defective slot but the RAM was at fault so finally the system started with the other 4 gig stick. I didn't go to any repair shop as most of them just try to rip off, so thanks to you my potato pc started again.

[@brucepreston3927]

So the first 2 that get stuck on Dram light, I think you are correct mostly...I've seen this a bunch of times...It usually happens when the SOC voltage gets set too high and damages the memory controller...It really doesn't like getting overvolted too much unless you have extreme cooling...

With the overheating CPUs, try delid and liquid metalling the CPU and putting the IHS back. The thermal glue inside might've dried out or not making contact with the IHS anymore

[@Solrak8O]

I believe all Ryzen CPUs are soldered to the IHS

[@TBomb85]

Yeah, they're all soldered... But maybe badly. I second delidding

[@alltheboost5363]

I would love to try to delid that 5900x and see if it's a contact issue. Maybe there's an internal issue where the chip is barely touching lid. Or maybe try turning one of the CCDs off amd try running at stock settings.

[@frederikmoeller88]

Hi Greg Thanks for the always informative, and thorough videos. I wonder if you would share some Fix or flop statistics? Do you have as many faulty intel processors as ryzens? Put up against how many you got it in?

[@HuShang]

I had the exact same issue as the last CPU that you tested here. Tried underclocking as suggested and everything seems to be working now! Thought I had tried everything... Thanks!

[@jamesmiscellaneous]

Great video man. I also like to revisit things to update that mental database where you think you had it figured it out, but in fact did not. Wonder if mem controller is getting torched or an issue with going to aggressive on the F-CLOCK damaging Infinity Fabric? I wouldn't know, I'm only a measly ZEN+ owner and haven't over clocked anything since boost clocks have been implemented in CPUs/GPUs. I'm from the old era. Overclocked my Athlon with a #2 pencil and then a car defogging repair kit. 🔥

[@JMatrx]

I was looking forward to this, since you had quite a collection of dead 3000s. To be honest I recently built two absolute equal 7600x systems, did the same settings on boths, same gpu, same EVERYTHING aside hard drives. One was running at 1.4v, the other at 1.29. The former was almost hitting 95°C (on a Dark Rock pro 4!!) the other was running relatively cool in the 80ish pumping better scores all over the place. I've ended up forcing a Curve optimizer on the 1.4v basically that reduced it to the voltages of the other (even less at -30) and the thing began running cooler than the other and posting roughly the same results if not a tad better. For safety I set the owner to -20, then instructed him how to lower it by time as soon as he checked that he was stable in his editing/gaming/daily routine. He now runs it at -30 and at least in Cpu-z/R23 he gets results slightly better than the other that I've left at stock all while running about 5°C cooler overall. The above was kinda strange tbh.. same b650M-A pro from MSI, same coolers, same Asus Tuf 6800Xt, same evga supernova G6 850, same g.skill 6000 c36 kit 2x16, same crucial P5 plus, same bios version, same bios settings (at default + just enabled XMP and fan profiles), same Phanteks p500 the only difference was one rig has a 2Tb HDD + 256 sata SSD, the other one just a 3Tb HDD carried over from their previous builds. But that can't be the humongous vcore difference. The only test I didn't do is to swap CPUs between the motherboards, but looking at how the CO cure turned out, I thought I didn't wanted to dismount and remount two Dark Rock Pro 4s 4 times in a day..

[@kyzh99610]

some AMD chips that have dual CCD(x900, x950, or some x600 series) may experience some impedance between CCDs especially when theres a degradation problem related to the silicon, their voltage needs heavy adjustment to work normally. TechYESCity demonstrated that by disabling cores/limiting boost frequencies some of these chips could be salvaged.

[@sp00n]

A motherboard with debug codes instead of just LEDs (and a power button) would've probably been beneficial for these tests. Or regarding the power button, you could just use one from an unused case to connect it to the pins instead of having to short the jumpers all the time.

[@daveward4358]

Same here. I thought they were going to be sent back to AMD to test them?

[@JCmeister9]

[@JCmeister9]

@@daveward4358 Not necessarily, only because we can neither confirm or deny if that's true without proof or evidence. What I can say for sure is that, there were a lot of people who bought these CPU's, so it's possible that failure rates can seem to be higher than what it truly is overall.

[@mrm90000]

I just want to say thank you for the fix or flop content! Thanks to your methodology I was able to fix a friend's "dead" PC in less than 15 minutes. He thought the mobo was dead and asked me if I could look at it knowing that I have experience building PCs, and I was quickly able to narrow it down to just 1 dead RAM stick. I cleared the CMOS, swapped in a known working GPU, and then tested RAM one stick and one slot at a time. It was so satisfying being able to save that PC as it is still a relatively powerful system.. i7 9700k on a gigabyte z370 motherboard with an RX 6700xt.

[@abdulhkeem.alhadhrami]

[@b0ne91]

Make sure to disable some cores in the BIOS to see if chips will run afterwards. You can try manually increasing voltages or lowering clocks too. Sometimes some cores will die completely, other times just enabling PBO or even any boost frequency at all will be the issue. I've also seen it where it would basically need an extra 50mV to hold the advertised boost frequency. Mostly, these chips can be saved if you're willing to make compromises.

[@justinmitchell5732]

Thanks for the follow up. I would like to see if any of the mobos are salvageable.

[@bacardimonk]

Hey Greg, love your Videos. There is a possible workaround for those 3600's that are sticking on dram, Put in a working CPU, then goto BIOS and undervolt and downclock the ram speed. I have seen a LOT of 3600 and 3600x that after a couple of years developed a problem with ram speed

[@arbiter-pe3xg]

I reckon it would be interesting to see these delidded and see what the components inside look like or if there is any thermal damage to the silicon dies

[@nordlicht1881]

Hey Greg, Did you check thermals with the 5900x or not? Would have been easy to see if it's a thermal issue once in windows, because if it still goes up to the 90s in temperature with reduced settings like this, there must be Some kind of IHS contact issue internaly causing thermals to rise. Greetings!

[@Enjoymentboy]

The labeling of the cpu as "bad" reminded me of a system one of my clients asked me to diagnose and the only information I had to go on was the label which read "doesn't".

[@shaneeslick]

G'day Greg, This was really interesting, just a couple of thoughts for some more testing, Do you have another 5900X to get some BIOS 'Full Auto' Setting Stats running GB to compare Score, Temps, Core Voltage & so on, it would be interesting to see how this 5900X performs if you increase the Multiplier to see where it fails at 1.1v, also see if it boots with Volts - Auto at 3GHz & some other testing of this type, 🤔Maybe it could be a Live Sream ???

[@jonathanmaybury5698]

I have a Ryzen 72700X. Where one memory channel crapped out. What happened was I changed my cooler for one of those tower coolers and the weight on the tower cooler ripped the Ryzen out of its socket, and I am guessing that that caused some sort of electrical faultin the CPU, as it doesn't like being pulled out of its socket when the power is on. But that's what happened. The main fault lies with the top-heavy weight of the tower cooler and the CPU retention arm. The weight of the cooler pulled the arm out of its socket. There was an easy fix for this and that was to bend the arm towards the socket again, making a better contact with the catch. But by then it was too late. My verdict is --- Tower coolers are too top-heavy and the CPU retention arms are too weak and don't latch hard enough.

[@jensenambrose3333]

I find it interesting the number of memory issues. Just replaced my 2700 X as the memory controller is depredating. It stopped being able to run the memory on XMP, so I had to drop the voltages and speeds down a few months ago(6) and it was stable until yesterday when the problem made a return. However, I believe a bad bios was to blame in my case as I found that the XMP had gone 1.45 V on Auto which was fixed with a bios update.

[@brianm.595]

Should try de-lidding the ones that you think overheat internally. it might be interesting to see if there's something odd with the compounds between the chips and the IHS. Also, lol suggested re-naming your old videos in comments during one of your recent videos.

[@MasterN64]

If you install poorly it is generally VERY easy to tell why it is broken. Bent pins or massive damage to the socket itself or conductive thermal paste in the socket for example. Thermal loads could cook a chip in theory but in general its not something that will generally cause a chip to fry since people will normally notice something is wrong even if they arent tech literate. In reality though the truth is that no QC is perfect and every company makes lemons or has broken parts slip through the cracks. Or even parts that pass QC if only barely so they fail quickly. Thats one of the reasons you generally want to stress test a new system for a bit after you build it. If something passed the basic QC at the factory but has an issue when its ran hard for a long period its best for it to burn itself out early.

[@tomr3422]

Most properly working CPUs will shut themselves off well before any cooling related damage can happen,

Greg, I don't know whether this interests you, but for bench testing a motherboard, I use a removable, external power switch. I like this better than physically shorting the power switch pins when I have to start up the same board many times. Of course, if you are working with a number of different boards at the same time, this would be more time consuming than shorting with a screwdriver.

Just curious about using older GPUs to test. I have an EVGA 750 Ti which I use just to get a video out when I build a new PC if I don't have a GPU for it yet. On a couple of occasions I will no get a picture out even though I know the card and the rest of the system is fine (these are all Ryzen systems). It seems to be a BIOS issue. In one case I downgraded the BIOS (the motherboard had a dual BIOS switch). I've had this situation probably three times total. So, for me, using a "known working" GPU doesn't always work. Perhaps it is because it's an EVGA card, not sure. It has happened with an EVGA x570 motherboard and an MSI x570 motherboard, both high end boards. In one case, as I said, I downgraded the BIOS. In both cases putting in a newer GPU worked fine when I had one available.

The stubborn one is particularly interesting, obviously there's a clock speed for every chip that it simply won't exceed, the silicon lottery, sometimes chips are particularly sensitive about voltage at a given clock. You went the downclock and undervolt route, but I wonder if you couldn't push up the voltage to run at stock clocks. Overheating is one explanation, but it's equally possible it's the silicon itself that is defective and not the heat spreader application, heck it could be 1 core in the cluster of 12 that's not behaving nicely. If it's a die problem and it runs undervolted that makes it actually a decent chip, just not for an application that needs the full clock or potentially core count. Taken individually anyway it would stomp on the E5-2670v3s in my home server that does plex and game hosting. The one with a single dead memory channel also has some potential for re-use still as a gaming CPU even just with the understanding there's gonna be diminished performance, the application I'd probably use it for though if it were mine is in an openWRT router build for multigig networking after pulling the clocks down for efficiency.

About dram issue, try pressing cpu a bit harder to the mount. I saw ONE cpu where mount pressure needed to work consistently was a bit unreasonable. Maybe that was not one time wired chip. Just FYI try different slots for gpu and drive, sometimes you have just tiny part of the cpu shorted, and for example m.2 slots are unusable, but otherwise cpu works. Disable that part in bios, and you have yourself working, although crippled a bit cpu. It's not wired that same skews have same issues, it's likely that same type of machine made same mistake. Likely there is some kind of trace that is just a touch too small, and if combined with some other issue, maybe mount pressure too weak or something, just fries. Weak mount I find is starting point to this kind of issues, where cpu kinda works, but use while using very specific thing like avx512, it turns off or freezes. For Dram, try LP modules. I have no idea if they would work, but it would be interesting to find out.

That seems like a lot of fail rate but since they were from send in units vs randoms. Only thing i'd suggest is trying them on a different MB had some issues with one of my amd cpu builds using a b550 that went away when I used a better board. The b550 seemed like it was trying to force the cpu to work via bios updates vs actually being able to support the chip haven't had a problem since I changed the MB.

Hey Greg! I hope that you having a good day, I was wondering if there is a significant difference between a 360 mm aio with fans set to exhaust and a 280 mm aio with a push pull configuration.

[@sxpphxre]

Push/pull mostly doesn't make a huge difference for standard thickness AIO radiators as they're not thick enough for one set of fans to have trouble pushing air through. In this case, all other things being equal, the push-only 360 should have the higher heat capacity. However, as you get to thicker rads like the Arctic LFII or the sort commonly used in custom loops, push/pull becomes more relevant.

[@bogdankowalski7132]

interesting on the first cpu tested, i also had that same exact issue on my R5 2600X on a B450 Aorus Pro. The error lights on the mobo would be solid dram with a flash of cpu sometimes. The thing is that my computer would actually boot after i let it blink the error for a while (sometimes a few minutes, sometimes like 10mins. other times it wouldn't boot for a long while so i would turn the psu off and on and it would hopefully boot soon later, also i would reset cmos sometimes if it doesn't want to boot for a good while and resetting psu didn't help. also i don't remember if this did anything but i recall sometimes flipping the psu switch off and back on really quickly as a potential fix) I upgraded to a R5 5600 not long ago and it wouldn't really do it anymore. Not sure if it was an issue with the CPU, or maybe an incompatibility with something in the Bios? potentially also memory, when the pc would boot after doing this (this error thing would only really happen on 1 in 6 boots or after the Psu was turned off and on) the memory xmp profile would be off and going into bios it would say it was reset to default settings. edit - specs - initially - R5 2600X RX 580 2x8GB 3200 ripjaws V noir CL16 B450 Aorus Pro (bios was up to date although sometimes got reset to a lower version when the error occurred) Later upgrades, in order - 5700 XT, still had issue 2x8GB 3200 Corsair Vengeance CL16, still had issue. ran both in configs 16GB corsair and later 32GB mix. R5 5600, 'fixed' issue of this error recurring for no reason, though it would usually still do it on first boot after the psu was turned off. 🤷‍♀️

[@VESTECHGAMING]

At 17:28, was that a spark under the motherboard when he flipped the switch on his PSU?

[@brucepreston3927]

It sure looked like it! Good catch, I never would have noticed that...Though it could just be a trick of the light from him moving around

[@kisrucs]

RGB Leds, on power first white light... ;)

[@DankerTVTimeCapsule]

Maybe contact Steve from gamer nexus. This sort of situation might be down his alley. Especially if it shows to be a batch wide situation There could be hundreds of Ryzen 3000 chips on the verge of going bad and could open exactly why they could be turning. Might turn into an interesting collab.

[@Doug-mu2ev]

Love your debug GPU! Cute

[@evanchadwick4900]

Hey so I have a question about dram channels on cpus. Is there anyway you can fix the cpu like take it apart at all or no

[@MiddleWestOfficial]

@GregSalazar for the 5900X try to Enable PBO instead of Deactivating it. And try out to activate the Eco Mode (75W/90W) inside of PBO. I had the exact same Issue, with an 5800X. At Stock Settings it was Boot Looping all the Time until i used the PBO Eco Mode and it wasnt even much slower. Like around 5-10%.

[@andrewalexander9508]

Randomness random point. I had a case that one of the pins for the power button got disconnected. Anyways main point you can get a 2 pin, to power button cable. I know you are comfortable with the screwdriver, but if your test boards don't have a physical button it might save some time to get a standalone button you can plug in.

[@darksylinc]

When doing these sort of diagnostics, CPUs have a system called by various names "CPU Internal Error" "CPU IErr," or "CPU Machine Check". This system is basically in charge of double checking results, e.g. that the CPU didn't do 1 + 1 = 3. When such error is detected, the CPU will (try to) tell the OS and the OS will log the error and reboot itself (sounds familiar?). This may require a few tries because sometimes the error is so bad the OS doesn't get the chance to do any of this and the system just hangs or reboots. In the case of Windows, you'll find this in the Windows Registry Log (kinda hard to reach when you can't boot). In Linux, you should see it right on the boot terminal on screen right before reboot. This is very useful because it may indicate further info as to what is failing; and you may find workarounds online if others are having the same issue. I suspect the 5900X was having Machine Checks, and the 3900 from 9:55 may possibly too. Trying to boot into Linux may also yield more info (particularly if it gets stuck in a specific place)

Hi Greg, I have a ryzen 5 3600 with aorus b450 elite. My pc wont start, and no light debug show in motherboard. Is the motherboard dead or my processor was dead? Help me, thank U

[@nuclearmonster]

Great episode! Very curious if AMD ever tests these, too.

[@mubarkroyal7894]

6:27 There was a spark on the cpu socket when you turned the power on

[@Rlinsenbach]

Just a thought. With multiple generations of Ryzen CPUs and a b550 board. Often the qvl list varies between each Ryzen generation when it comes to supported ram on an individual motherboard. Ram could be a factor too.

[@BiggestMichael]

With the 5900x, maybe you could run Ryzen Master and see if setting PBO Per Core and Auto OC to see if you can get any performance back.

[@ibanix2]

But can any of these get replaced under warranty?

[@oldmanwithers4565]

Have you seem Brian from tech yes city video on dead ryzen cpus ? In that it's one or more cores that have died. He gets a round it by using an identical cpu to disable cores in the bios.

[@giovannip.1433]

Would slowing down RAM speed affect the capability/function of the CPU memory channel?
