Not sure if I can rma my cpu

I have an i5 9600k. I got it from overclockers back in December. It has started to degrade and die on me. I had to disable turbo boost just to get it stable. I'm wondering if I can rma it. I overclocked it for a couple of hours when I first got it. Also I was running xmp for a few months before the failures started and as far as I'm aware, intel dont like that.
 
If you OC your CPU you void your warranty, even on a K chip. I'd ask OCUK if they are willing to look at it for you.

Have you swapped out the RAM to check it isn't that?
 
I figured as much. I'm not sure I want to go bothering them with it either. I just need to take it as a loss and get on with it.

Yep I swapped out the ram. It was the first thing I thought of. I actually bought another kit to test it and it made no difference.

Fyi, the errors im getting.

First sign of anything was blue screens. DPC Watchdog violation. Caused by intelppm.sys. It stops responding. This was happening through certain games and cpu intensive apps. Benchmarks for example.
Then came the errors in prime 95. Rounding errors while running small fft. "FATAL ERROR: Rounding was 0.5, expected less than 0.4 Hardware failure detected, consult stress.txt file." This started as an occasional thing. Now it happens every time i run prime95 small fft with the cpu at stock turbo boost speeds.

Like i said but, i figured out that if i turn off turbo boost, it starts running stable.
 
To be honest if it is a retail boxed CPU, just RMA it with Intel, 99.9% of the time they will just swap it anyhow.
 
I'd try to RMA it but make sure you set all the values so that they are not overclocked. That way I'm pretty sure Intel won't realise it has been overclocked. Might as well try!
 
I doubt very much they will even look at it. They will see if it works, if it doesn't it's in the bin and replace it. Are you sure though it's not the motherboard? Most overclocks involve the motherboard in some way and CPU failures are pretty rare. It's more likely to be the motherboard.

There is no way to tell, the board tells the cpu what to do not the other way around ;)

It's def the cpu. I tested it in my brothers rig. It does the same thing no matter what board it's in. Also I only overclocked it for 2 hours when I first got it. Its been running at stock ever since. Interesting little fact, its always the same core that fails prime95. It probably has a faulty or weak core.

You got a dud. If Intel are anything like AMD they will pay for all the postage and have a new chip out to you in a few days. I RMA'd a 2700x (because i fried it) a month or so ago and it was the easiest RMA ever. Sent the chip, had a retail box new chip on my desk a few days later. I would expect the same to happen here.

Okay I didn't know that! Only built my first PC a couple of weeks ago!

Awesome stuff, welcome to the fold :D How are you enjoying the new machine? I'm sure one day cpu manufacturers might try and put some sort of way to tell in them but I can assure you there is nothing like that in any current gen cpu so far as we know. Providing the chip is clean they are very unlikely to be able to tell exactly what happened to it without inspections which are likely not worth it on the odd rma within a given batch. At a guess it goes in some sort of batch database that they monitor for unusual failure rates, once some sort of marker gets ticked they might then look closer into that batch to have a look if there was any production issues. Given the volumes and rate of failure within warranty, my bet is they barely look at the duds.
 
Just an update.

Atm intel have me doing loads of tests and screenshots. I enable turbo boost (which I turn off to keep the cpu stable) gave them screenshots of the prime95 failure and run some intel based tests. I will say my cpu passed those intel test but they don't run the cpu as hard as prime95. I added a "whocrashed" screenshot of a blue screen dump that shows the intel cpu driver stopped responding and triggered a dpc watchdog violation blue screen. Just waiting on a reply to that.

Intel Burn Test does stress the CPU harder than any day to day scenario.

But it still doesnt stress the cpu as hard as prime95. The temps give it away. Max temps under the intel tests was 55c. Max temps while running prime are 65c. Prime95 generates more heat.

The new machine is great! Feeling a little down about the new RTX 3000 series. I got an RX 5700 XT but it's nice for gaming nonetheless.
