Hi guys,
I have an issue where even the slightest overclock causes random hangs. For example, If I run at full BIOS defaults, the system is stable. But as soon as I bring my cpu up to even 4.2GHz (which is its stock turbo boost) it will at some point within a hour or two just stall. This is the buzzing of the last sound played, no BSOD or event viewer event beyond unexpected shutdown, just a hard stop and requires a hard reset to fix. For history, my CPU was previously stable 4.5GHz @ 1.34v with super crappy, mix and match ram, but due to prior air cooling constraints was down clocked to 4.4GHz @ 1.28v. I recently upgraded from SLi 660 Ti to an MSI GTX 1070 Gaming x. I was seeing 60% GPU usage and 90% CPU usage in certain games with poor framerates, but couldn't afford to get an intel CPU and board. So I replaced the venerable Hyper 212 evo with a corsair H110i and got a decent RAM kit to really push the ol' 8350 to reduce the CPU bottlenecking. At first, everything seemed to be working fine at 4.7GHz 1.45v (51c under Prime95) after a few days the freezing began, I started reducing the clock speeds a little, it would be fine for a week or so, then start again (if I didn't reduce speed it would happen every hour or so) Then I thought it could be that my IMC couldn't handle the 2133 speed, so I dropped my RAM to the rated 1866, didn't help, I went so far as to drop it all the way down to 1333 with the SPD timings for said speed, no difference. I reset the bios back to default and stability returned, started grasping at straws and furmarked my GPU, and noticed that my overclock on the GPU started dropping within the first minute, but the temp was only 61c. So I fired up GPUz and looked at the perf cap, which was pwr. However TDP was capping out at 87% (when it's set to 125%), running a 7 threaded prime95 alongside of furmark exacerbates this problem, further dropping GPU TDP down to 79%, which is what lead me to thinking that my PSU is dying. I purchased my PSU in Jan 2011, so I won't lose any sleep if that's the case. I just don't want to throw money at the problem without a reasonable degree of certainty.
PS: I 12 hour memtested the ram as soon as I installed it
My apologies if this sort of thing has already been addressed, I couldn't find any definitive answers on my own.
