Hey guys,
Posted here a little while back when my CPU died the first time and got a lot of great advice so thanks again for that. Long story short:
i7 5820k/i7 6800k
Gigabyte x99p-SLI
Corsair H100i
Samsung Evo 850 pro 500gb
Corsair Vengeance 24gb RAM
Corsair RM650i PSU
Had a 5820k running in my Gigabyte x99p-SLI. This was overclocked to 4.4ghz I believe, can't remember the voltage but RealTemp said it never exceeded 65 degrees during stress tests. After a few weeks of heavy use in audio production, the computer began hanging, then one of the screens stopped working, then blue screens, until finally the computer would not get to post and was in a permanent boot cycle. I reset BIOS settings to optimized defaults before the final blue screens, which either made no difference to what was causing the damage, or the damage had already been caused. After extensive testing and troubleshooting, I ended up taking it back to the shop I bought the components from and they diagnosed it as a dead CPU and offered me to upgrade to a 6800k for $50, rather than going through the whole RMA process.
After having installed the new 6800k, everything is back to normal, no issues for a couple of weeks. I had a project in which I had a lot of processing going on, which relied on the overclocked CPU to be able to playback audio in the session. I went through the OCing process again, and settled on 4.5ghz at 1.5v which was stable and temps never went above 69 degrees in stress testing. A week a two later brings us to now, and the same symptoms as before have happened. This time I managed to grab the blue screen error code before the computer stopped being able to POST. "Crypto Library Internal Error". A bit of research suggests this is again a CPU failure, as well as the fact that it is exactly the same story as last time. I have a few ideas as to what could be causing it and I'd really appreciate the input of all you guys.
I feel like 1.5v is quite a lot of voltage, and 4.5ghz is quite high for a 6800k. RealTemp and CPU-Z both read the correct clock speed and say the CPUs aren't overheating, but is there a chance that RealTemp was inaccurate, and both times I have been overheating the CPU, but not to the point that it shuts itself off and never knew about it? Or is it more likely that the PSU or MOBO have an issue? Also, what's the likelihood of receiving two CPUs that were both faulty?
I need to get this rig back up and running for work. My solution at this point is to replace the CPU one more time, see what I can get done without the overclock, and wait until the shop's technician returns from holidays and is available to test all the components.
Many thanks, I look forward to any and all replies.
Cheers
