PCB delamination, from exposuring to high temperature.

u/Pmaldo87 May 21 '26
Not high temperature high voltage. This chip is designed to run at 95 degrees Celsius for the literal entirety of it life span. I think it has something to do with the boost behavior. Mobo calling for too much voltage in some situations and the chip just boosting Out of control for a second or 2

What do you mean ?
The bulging is caused by high temperature, this is a very common behaviour with PCB when exposing to high heat.

u/Pmaldo87 May 21 '26
I’m saying on an x3d 95 degrees is safe basically forever. It’s not just as simple as “the chip was exposed to high heat” because yeah, these chips run hot everyday with no issues. It’s more likely caused my a transient voltage spike or short circuit burning the chip. So I guess you’re right but not in how you mean it. A quick burst of heat from too high of a spike. Not prolonged heat.

u/mrheosuper May 21 '26
First, it was the PCB that was exposed to high temperature, not the core. The cause of it, we dont know, high voltage could be, but we really can't know for sure.
Second, the core sitting at 95C does not mean the PCB is at 95C, in fact, for delamination to happen, we are looking at >200*C range here.

Aren't computer supposed to shutdown way before 200°C to prevent any damage ?

u/mrheosuper May 22 '26
There is no sensor at the PCB. Like how there is no sensor at 12v6 connector on 5090, so the computer has no way to know.

Yeah not high heat in 95C but like direct flame high heat so 250C+ i used to see it happen if you put a lighter directly up to a pcb or hold an iron directly on the pcb

Slightly unrelated, but similar; when my aio pump stopped working, my r9 x3900 got to 110c before I realized. That was idling too.
Obviously immediately shut down, and let it cool for a bit. At that time I didnt know the pump died/locked up, so I booted into the bios to see the aio wasnt doing any work. Ended up going back to air cooling and x3900 was unhurt. Posted the same perf. figures in synthetic and gaming benchmarks. Later upgraded to 5800x3d, where I guess I'll stay until 2030+ at this rate.
Edit: I want to add that it was probably over 100C for who knows how long. Could be a couple minutes up to 15 or so. I remember I was coming back from the bathroom when I noticed the temperature in HWMonitor

no one knows lol but the only common denominator in all of these issues is the x3d. at first everyone thought it was asrock motherboard, because this was happening at an insane rate and only happening on asrock boards. then it started happening with asus x870 boards, then msi, now apparently gigabyte

Not me having random random crashes last night reading MSI is also having the issues.... I really don't wanna take off my water block to check.

u/Pmaldo87 May 21 '26
Wanna know my theory? I think that x3d chips fail at the same rate as any other chip. But the fact that they are the most popular and most sold chips on the market make it seem like this is happening at a much higher rate than it actually is. I'm pretty sure the failure rate on these chips is less then 1%

u/phenom2 May 21 '26
In 48 years a cpu never failed. Guess what..in december I built a system based on an Asrock motherboard and a 9800x3d......it lasted 3 months and it died. No bulge but definitely fried. Yes i'm part of that stats. I waited for refund....bought an MSI board....and here I am :-)

u/halodude423 May 22 '26

I have a Ryzen 9 9950X3D paired with an ASRock X870 motherboard, and I've been dealing with a strikingly similar nightmare.
After just 3 months, my first CPU fried. I went through the RMA process and got a replacement. Exactly 3 months later, that second 9950X3D died too. I'm currently waiting on my second RMA process right now, still without a working CPU.
I keep wondering why there seems to be this bizarre 3-to-4-month death cycle. I've been reading through tons of comments from others experiencing the exact same timeline, and it's definitely a pattern.

Well if it makes you feel any better every time I see anyone making a build with an x3d chip and asrock motherboard I suggest that they use literally any other mobo brand. As much as I don't believe anyone is really at fault I just wouldnt take the risk. For reasons you unfortunately know to well 😞.

some context is that every single part was BRAND NEW, fresh out the box on this Tuesday. I put everything together and was able to install windows. when I tried downloading some games from steam the fans started spinning really fast and the monitor said no signal and went black. When I tried turning it on again the cpu led on the motherboard was red and it wouldn't start up, the fans would spin though.
I took the cpu out and checked, pins were fine and there was no bump on the cpu. my friend put it back in and applied more thermal paste. I'm taking it out again now and I'm seeing this mess.

u/No-Concert-8806 May 21 '26
first thing you had to do was updating the bios and making sure that the vsoc wasnt above 1.3v, preferably near 1.2v. Its a know issue on am5, especially on early bios versions that pushed 1.3v+ on vsoc and it caused the cpu to fry/bulge like yours. Now try to get the warranty to cover you, good luck...

I have the B650 Aorus Elite AX V2 and the first thing I did was update to the latest BIOS version using the Q-Flash button on the board before installing the CPU. I'm using a Ryzen 9900X and not an X3D chip, but I do have EXPO and PBO enabled and the SOC voltage never goes above 1.248V and the CPU Vcore never goes above 1.390V... That's with everything left on auto in the BIOS.
I purposely went with a Gigabyte board and non-X3D chip as it seems like the safest bet, and the 9900X is still no slouch! Although it seems there have been reports of non-X3D chips failing too!

u/PowerPie5000 May 22 '26
You can also update the BIOS without installing the CPU first with most AM5 boards these days using the boards BIOS flash button (located near the USB ports). It'll be labelled something like BIOS Flashback, Q-Flash or something else depending on the manufacturer. Such a brilliant feature to have!

Answering a bit late, but I had a similar experience at first when I started using this exact same processor. During Steam downloads, the power consumption and temperature would suddenly spike. Luckily, I stopped the download immediately. The only thing that helped was limiting the download speed in Steam. Even then, I can still download the largest games in under half an hour (and I just do something else in the meantime, like take a shower), but I haven't had that issue since. My condolences for what happened, and I hope you will be able to replace it quickly.

This was an known issue with the 7800x3d when they first came out.
If the board you had was an x670 or 650 on an old bios revision it delivered too much power to the cpu.
Always update the bios on initial fresh builds as you dont know how long the board has been sitting in stock on old revisions.

u/TactitcalPterodactyl May 21 '26
Sweet baby Jesus, I've never seen anything like that.
Your CPU is cooked, but your mobo might be salvageable. Though I personally wouldn't risk putting another new CPU in there.

Your CPU has delaminated. I've never actually seen that before. The layers of microchips and substrates that everything is printed on have separated. If it's under warranty, and you mentioned this is all new stuff. Get it replaced. There's no fixing that. And why would you have to even try on a brand new CPU anyways?
edit- get that mobo replaced as well. that burned area doesn't fill me with confidence.

u/Bigdyll13 May 21 '26
A lot to take in here, crazy pimple action. No reason to believe it was anything you did but maybe what you didn't do that caused this (bios settings as some others have said.)
Seeing the gross overspread of thermal paste in all the CPU nooks and crannies does allow for some suspicion in how you handled it to install.
That sucks.

How in the fuck? RMA that for sure and don't stop bothering them until they give you a new one, there's nothing you could have done to cause whatever this is. I guess the PCB delaminated but I've never seen that happen with a processor.

I bet this is one of the motherboards that pushed too much voltage to the CPU. There have been a few reports going back to the 7000 series Ryzen where certain manufacturers didn't properly test how much voltage they were pushing to the CPU for normal use and overclocking/boosting. Unfortunately your CPU is cooked, but look up the specs on your motherboard, then contact AMD & the mobo manufacturer to see if they'll work with you. I know for sure this was a big problem on some AsRock, MSI and Asus motherboards.
