Fix or flop is getting intense!

[@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.

[@AmosCheek]

Brian at Tech Yes City had similar issues with some Ryzen chips and found that some had bad cores and was able to get them working by disabling a core

[@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.

[@skerlone]

for the chips that do boot in to bios you could try turning cores off, first try to see if it works ok with only 2 cores then enable 4 and so on to find out maybe a 6 core can work fine with 4 cores

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.

[@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

[@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...

[@hoodie_ninja]

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.

[@Roger44477]

Was wondering when we'd get this video since you've hinted at it a few times

[@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.

[@mikemarkong]

This video's great! the monologue of troubleshooting shows how people may want to try to do when they encounter problems with their systems.

[@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.

[@annettesurfer]

Recently I had a family member complain that shortly after plugging in his new WD 2TB Elements portable USB 3.0 (the next day actually) his monitor, keyboard, and mouse quit working. I saw that his MSI X470 Gaming Plus Max AM4 MB had every USB port filled with various crap...looked like a porcupine. His poor Corsair VS 450 PSU had to handle a Kingston 120GB SSD (OS boot drive), a WD 250GB HDD, a Seagate Barracuda 500GB HDD, the Ryzen 5 3600 w/stock cooler, 16GB G. Skill Trident Z Neo 3600, 5 UpHere RGB case fans, MSI GTX 1650 Super GPU with 2 monitors plugged in, and some gadget that appeared to have a few mini monitor screens. All the fans and lights were working, as well as the GPU fans. I noted the PSU didn’t have a connector for the 4-pin CPU PWR2 on the board, which I’ve read the MB only really needs the 8-pin CPU PWR1 but I can’t help but wonder so I suggested he buy a more powerful PSU to handle all the stuff he had plugged in and to make sure it had the connector to fill that void. Well a new Tier A Corsair RM1000e PSU didn’t help so I tried a known working GPU but that didn’t help either. I should note that no settings were ever tinkered with. Everything was totally factory and his Metallic Gear Neo case w/2 Skiron RGB fans, plus the 5-pack of UpHere RGB fans offered plenty of ventilation. I thought for sure the motherboard had an issue. The next stop was Micro Center for component isolation, which took 3 weeks and they said the problem was the Ryzen 5 3600 failed and it would be $180 to fix. He added that although he just bought everything last summer, (from MC) he didn’t buy the warranty so that’s something he’d have to handle himself through AMD. Noting how many of those chips have been diagnosed as “bad” plus the one I mentioned, I’m beginning to think AMD may have a dependability issue starting to emerge. EDIT: MC scared the kid by saying the new CPU would require a new OS and it would wipe everything on the drive. When the kid asked about saving his games and the cost of the next CPU upgrade. The tech said the ($129.99) Ryzen 5 5600 was actually just $20.01 more than the ($109.98) Ryzen 5 3600 and mentioned flashing the MB. So with another $150 to save his data, the price approached $500. I suggested that since his OS was on a cheap $20 120GB SSD that he should just put in a higher capacity & faster NVMe for the OS and the old SSD wouldn't have to be touched. Plus he already had the activation key from the previous OS installation. Next thing I know, the tech installed the ($49.99) Inland QN322 1TB NVMe and ended up costing “$200 something.” (his words)

[@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..

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.

I agree....cooling IS an issue with the R5-3600 if you use the pitiful cooler supplied with the CPU. With a good cooler that keeps it below 65C no matter what...mine has been absolutely reliable...so far.(knocks on wood)

[@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.

[@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)

[@dgorry]

It makes sense that the IMC in AMD chips fail more than non K intel chips. The more freedom you give users the more variety you need to support ram wise. Running outside of its preferred settings with higher clocks and tighter timings is higher risk. Similar to turning up the boost on turbo cars. It puts pressure on other parts: clutch, fuel system etc.

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.

[@christopherfarrell-artist3557]

I am wondering if the silicon shortage over the last two years has contributed to this issue, are manufacturers reducing the failure threshold/overhead to pump out their products?

Well not quite bad as in non-functional but bad as in cannot operate at stock clock within stock voltage, and may have worked if binned down into a 3600 with 200mhz less base and 400mhz less boost, or if sold into an even lower sku like a ryzen 3 where 4 cores on a die would be disabled instead of 2.

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.

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.

[@MacCheetah3]

Preface: I may have a Ryzen 5 5600X with a failing memory controller. ... Throughout the past few weeks, I've been troubleshooting one of my PC builds. Around the same time as swapping graphics cards, my SFF rig became quite unstable, lots of random restarts. It freezes or reboots anywhere from immediately after POST to maybe 30 min in. The instability can be at idle, launching an app, activating the Start menu, closing an app, during a benchmark, etc. I've (re)verified the GPU, an RTX 4070 Ti, stability in another system. The previous card, an RX 6900 XT, is just as or more power hungry, therefore, I doubt(ed) a PSU problem. Many "clean" Windows 10 and 11 installs with various attempts at driver versions and driver install order made no improvement. When they would/could complete, benchmarks were fairly on par. I also changed the memory setting to Auto (i.e., base 2133 MT/s) and disabled onboard components (e.g., audio, Wi-Fi, BT) one-by-one via BIOS. Believing I've narrowed the culprit to RAM, CPU, or motherboard, I decided to do another DIMM reseating, though I swapped slots this time. Welp... This resulted in the board not making it through POST, lighting the DRAM Q-LED. No matter what, I couldn't get it passed the DRAM stage, that is, until I ran the system with only one DIMM. We're back to booting but still very unstable. I felt it improbable both DIMMs had failed. So, I swapped in a single stick of Kingston Fury (also DDR4-3200). System again boots, although, no improvement of stability. So, the problem appears to be down to the motherboard or CPU. And after recalling the failures you showcase in this video, I'm leaning CPU. A PC enthusiast wonders: is there any confidence to be had in either platform at this time? P.S. The PC in highlight is a boutique SI build, so no AMD warranty.

That CPU was part of a pre-built that had a warranty on the whole system, not by component (around here its not uncommon for a pre-built with off-the-shelf parts to have individual warranties) AND IT HAD A WARRANTY STICKERS ON THE CASE SIDE PANELS. My friend broke them since he isnt an animal and wouldn't keep his PC uncleaned for two years and because of that they denied warranty... I wasn't a fan of the company before and frankly their prices are far from great, but needles to say I don't even open their site anymore.

Techyescity tested few ryzen 3000 series cpu's and what he noticed that they are running pretty hot. He came to conclusion that running those "older" cpu's with modern graphics cards makes them run a bit too hot, which will shorten their lifecycle. Like the modern gpu asks too much from cpu. He was able to bring cpu temps down with undervolting

[@JoshsTechWorkshop]

I am curious what speeds the RAM was running at in the systems these CPUs with dead memory channels came from. Because, if I remember correctly, the RAM speed could affect the Infinity Fabric speed, and maybe there's a certain speed that, on certain chips, causes the Infinity Fabric to damage the Memory Lanes? Idk, I am just spouting off ideas that are popping into my head at 1 AM. Great work as always Greg!

[@p0gits02]

TechYesCity also had this overheating issue with ryzen 3600s. You can also try disabling cpu cores if undervolting doesn't work and see if it works.

[@lauciannailor8884]

I built a new AM5 system with an 7950X in November. A couple of weeks ago it wouldn't wake from sleep so after a power cycle, got the DRAM debug light (ASUS Tuf B650 plus). I couldn't believe that two sticks of corsair vengeance had both failed at the same time. After testing the memory (single sticks in all slots - 8 tests) then RMA'ing the motherboard and CPU; turns out the CPU had died. CPU always ran cool as I was running it on a 120w envelope rather than 170w, with an AIO cooler. Never had a CPU fail in 40 years until now.

[@joakimedholm128]

try disabling one of the cores or try baking them in the oven 150c for 30 min. the oven method has worked many times for me and some of the pc tech still works fine after 2 years. oh, and Greg u love being right, dont u;) pz

[@paulphillips8906]

Love the graded Yu-Gi-Oh cards in the back !

[@dareczek2974]

The last processor is not a problem with temperatures, only this processor is already degraded. So lowering the clocks helped.

[@ibanix2]

But can any of these get replaced under warranty?

[@randy206]

I have a viewsonic version of that portable monitor. I absolutely love it. High refresh rate and relatively good brightness and color. It’s a really nice thing to have around.

[@ericcales1598]

IIRC The 3600's have a max listed compatibility on XMP of 3200. I ran into a Ryzen 2700x that is listed as 2933 and it, more or less, meant it! I managed to get it set at 3000 and stable 99% of the time. I've learned to leave everything at "Auto" while testing, then once it's a fix or replace, I start playing with settings. The issue with the 2700x didn't start until they "upgraded" the DRAM to a faster, RGB type. The "upgrade" worked fine in my RIG and a test rig but I'm running 5000 series AMD and Gen 11 Intel. Just a thought. Understand that tis video is 11 months old as my eyes see it so you may, or may not, have already thought of this, retested or got answers from AMD about these CPU's.

[@dominicgoudos5859]

I got a problem similar to this, I got a MSI B 550 A Pro motherboard with a Ryzen 5 5600. Worked great for a month, no heating issues. One day I go to power on the PC and it does nothing. Changed out the PSU and ram, gpu. still the same. Then I took out the CPU and it fired right up, but the motherboard will no longer let me bios flash. Keep in mind you do not need ram or cpu in most msi boards with bios button.

[@jakesnow96]

Is that a Blue-Eyes Toon Dragon in the background? 😍 I think I also see The Winged Dragon of Ra and Relinquished, I could be wrong. I can’t tell what the other two are.

[@AshtonCoolman]

Did you clear the CMOS for every CPU?

[@lieutent2654]

The 5900x is a lot like a 9900k I had once. If you overvolt the snot out of it (1.45V Vcore or something) it’ll go into windows and work fine for a while, then it will degrade and eventually require more voltage or lower clocks. It eventually got to the point on the 9900k for me where I was down to disabling 4 of its 8 cores, and locking clocks at 4.0GHz at 1.4V. I just trashed it at that point.

[@MorDreadful]

The last one I wonder if de-lidding and some thermal paste renewal, then replace the IHS (I know it can move around after de-lidding but still) and then carefully apply the CPU cooler again and try running it on normal just as an experiment to see if it will run on auto for vcore etc. Just because cheap paste is usually used. I just wonder if it has been run too hot and the paste is too crappy and now failed. I think that would be a good experiment.

[@dasdoin9600]

i think the ihs is soldered on all ryzen cpus

[@DyceFreak]

I've been in IT for over 30 years and I've personally only seen 1 failed processor. Two users with failed processors would have been crazy to me, but 5!? Intel isn't the best but this is shenanigans.

[@Dan-Simms]

Would love to see a further video with a deeper dive somehow, or if AMD gets back to you with an update. And I love how you said at the start about learning from mistakes, that is one of the best ways, especially showing it off to us viewers.

[@616-j4r]

I got a little problem. If i use the recommended DRAM slots and use XMP the pc won’t boot. But if I turn off xmp it will boot. If I use another set of DRAM in the same slots and with xmp the computer boots… But if I use another slots and use xmp, the computer boots… with the difference DRAMS.

[@chrisblandford8971]

im about to get a 7800x3d and first amd cpu for me since athlon, should i be worried about the quality of these amd chips?

[@wisnudJat]

17:55 recently I also experienced this issue (boot to automatic repair), my solution is disable fast boot and longer time for display bios (3s to 5s)

[@iffyifferson]

I had a perfectly fine cpu in storage and gave it away to a friend, but it wouldn't boot. What made it work was rubbing the tip of the pins with tissue paper as if cleaning the tips. Thermal paste might have gotten to the tips somehow while I was handling it but we were just glad we didn't have to throw away a perfectly fine cpu

[@AmaraTheBarbarian]

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.

[@CrunkFunk]

You could set up one test bench with a dedicated PSU and just change out the motherboard on it when needed. It's not too much work considering what you go through with each build that comes into your studio. It would make troubleshooting GPUs a lot easier because you could just pop it into any MoBo you already have mounted on it. Love your content so any time you could save when creating the videos would mean more content you could put out accumulatively.

[@CrunkFunk]

Also, I have an AsRock B450m Steel Legend and on the bios page of the website, they recommend not to update the bios if you are using first or second gen Ryzen. Only to update it if you are upgrading or planning to use 3rd gen or above. So just referring to the tidbit about your B550 board being fully updated, it could have some compatibility issues with older CPUs.

[@smakfu1375]

The answer as to why the 5900x is stable in the UEFI environment, but not once Windows starts loading is pretty simple: UEFI environment is uniprocessor (e.g. only running on core 0). Windows' NT kernel, upon initialization, not only runs on each CPU (core), it has to initialize certain per-cpu data structures, etc.. A problem with one of the CPU cores, beyond 0, is likely crashing the system early in the OS boot process. My guess is it was overclocked and overvolted to the point of damage.

[@shotglass6334]

Maybe you should write the episode number on chips you mark as bad to make it easier to find what initially led you to decide the chip (or any other component) was bad. The one that you wrote "overheats" on might be a thermal expansion issue where either a trace on the substrate or bad solder joint(s) become disconnected as the chip heats up.

[@em6xn]

time for Hollister sponsorship ! Love this brand 👌

[@mubarkroyal7894]

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

[@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.

[@HardWhereHero]

I have 2 "Dead" 3600's and if i undervolt them they work fine. I also have a 3900x that only boots if PBO is disabled. We have a few 1600's with the dead memory controller. My guess? These are all low quality binned chips that were created close to the end of the MFG cycle and were bottom bottom bottom of the barrel, they were sent out into the wild. Overclocked and that was that. I could be wrong but I have ran into so many degraded chips that work if you undervolt / underclock them. All of them are Ryzen. That flash that you seen when the mobo powered off and then back on is Ryzen memory training. it takes literally a few seconds.

[@definiteIynotkenji]

Greg did you notice the spark at 6:28 would that be the cause of the issue?

[@skitx31]

Oh shit! Good catch

[@grumpyratt2163]

Another great video. Always learn something new

[@abdulhkeem.alhadhrami]

Been waiting for this!

[@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.

[@thomasallen531]

I always learn so much more from making a mistake then I ever would from getting it right every time.

[@Rayu25Demon]

I was expecting you to talk about these dead ryzen CPUs. Also, we may need another video about dead ryzen mobo as well

[@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

[@joelcarson4602]

Chiplets are one of the ways from now on to increase performance, but when first announced, I wondered about how long term reliable the early specimens would turn out to be. Interconnection issues because of thermal expansion and contraction seemed like a real possibility, especially when overclocking your CPU. Remember a few years back when there lots of Nvidia GPUs failing because of interconnect failures inside the chip between the silicon die and it's connections inside the chip package itself? Some folks were blaming the solder connections between the BGA pads on the bottom of the chip carrier and the circuit boards but that turned out not to be the case. I'm not sure that I would really overclock a chiplet based CPU, and would certainly get a better cooler than the one that came with it in the box. I guess we'll get a bunch of data before long with the Apple M series System In a Package which are basically micro system boards stuffed with various chiplets.
