Cpu stopped working 3950

no, it won’t post at all
This is what i'm saying, that little fella could well be done. I've literally even had a single stick of ram go bad before that caused odd boot issues. Replaced on lifetime warranty which was good but you never know when one of these things might go. Millions of tiny little transistors and whatnot all working together and allowing you to sit on a chair and have a random chat with some fella over the internet, tbh i'm surprised the failure rate is as low as it is. Either way something gone bad and ive pulled chips that look a lot worse than that and still work. That is what I would consider an enthusiastic but minor charing.
Will find out tomorrow when the new cpu comes, not had any issues at all with it prior to this, gpu is overclocked so I guess that’s possibly a suspect too, it’s only really the colour of those pills that’s making me think it’s cpu
Id be interested to find out when you do. Im pretty sure my TR isn't pristine under there any more and had a little bit of discolouration last time I had it out. Not sure what my little EPYC chip I have as an ornament looks like but one of the two I had was a little charred as well but that little fella still worked.
welp, replacement cpu no different, tried without the gpu and nothing so it must be the board.
Must be? Could still be the gpu or ram no? When you say tested without the gpu do you mean with a different gpu? Its not going to post without a gpu?
The motherboard has onboard HDMI on it
To allow any CPU with integrated graphics to output display, which the 3950X isn't.
I suspected the GPU when I read the thread yesterday and Vince mentioned the possibility. You likely have a dead GPU and it won't be the first that's died playing a Rockstar-made game. Had a GTX 680 that died in the middle of GTA V lol. System wouldn't power on with it installed.
You need to try with another, known working, GPU.
ah gotcha, will stick an old card in to check.
Pain in the behind however glad its not the CPU. What MB do you have ? could well be bad vrms for the power draw the 3950X pulls. Best check the GPU first though.

Not read all the thread but by the look of it, it looks like it's over heating. I've seen a few CPUs look like that after they have been clocked high and subjected to, to much heat.
It's like a tarnish/smoke damage sort of thing. Most should wipe off. If it's under warranty you should be good to send it back once cleaned up.

Well there's my above theory *crying-laughing-face*

Temps in the high 80's for 4 hours ? 1.35v with what is plainly not good enough cooling is enough to do that damage to a 7nm cpu.
The voltages you see under "Auto" are not sustained voltages. To give you an example, just running PBO on mine with a 360 AIO cooler i get an all core clock in CB20 of 4.18Ghz and a sustained vcore of 1.215v to 1.219v and temps of 65c to 68c.
I can also get an all core clock of 4.4Ghz at 1.35v, but temps go into the high 70's, not the high 80's. That is where your problem is, too high a temperature, as proved by the burning on the back of the cpu.
What motherboard is it ? I'm shocked that someone that has spent probably getting on for £1300+ on a GPU and £750 on a CPU didn't know that his cpu didn't have an onboard GPU
Bah its minor charing that is. I just checked and my epyc chips have chared pads in several areas of the chip similar to that and they are perfectly fine, I used them not long ago to upgrade some servers. Guess what the server cannot overclock them either.
Also doesnt matter on the nm of the cpu, those pins are not 7nm pins
my money is on the PSU either blew from load/age/power surge or the Motherboard died - it's the most common outcome for OP's symptoms. Next would be dead RAM, GPU and finally CPU. Dead CPU's with no other components affected are rare.
I've only ever had one CPU die on me, an Athlon 3800 x2 - it died during a lighting storm - power surge fried the PSU, Motherboard, CPU, and Hard drives - GPU and RAM was fine.

So took the whole pc apart and trying one component at a time.
Took the cpu out and cleaned it all, then took the motherboard out and dusted it thoroughly to make sure there was nothing shorting anywhere, maybe a loose bit of thermal paste or something, there was a couple of tiny spots around where the cpu went.
Just need tidy everything up again, cables everywhere, but happy to be up and running again without having to RMA anything.
