My mistake, I wrote the wrong chip earlier—the CPU is actually an i5 4670k.I'm running into some serious overclocking headaches here, and honestly, I’m starting to suspect the software itself is being inconsistent. It’s maddening. When I fire up Prime95, the whole system just freezes and reboots on me. Then there's OCCT, which is a total disaster; the error count just skyrockets, hitting 100 errors in a matter of seconds. Meanwhile, AIDA64 runs perfectly fine for two hours straight, and the Intel Burn Test holds steady through 10 rounds of the Very high 10 setting. I've got some screenshots to prove this madness.
Right at the start of the test... either CPU-Z is glitching out or it's giving me completely bogus voltage readings.

Just look at how fast those errors pile up.

Intel Burn Test

Prime95 after just a few seconds...

I've already cycled through the BIOS settings, trying it both with XMP enabled and without it. No difference whatsoever. Just more of the same headache.


At 4.3GHz and 1.230v, everything stays rock solid on AIDA64 and IBT. But the second I touch OCCT? Immediate Blue Screen of Death.
If I push to 4.4GHz at 1.95v, it manages about 15 minutes on OCCT before it falls apart, then Prime95 crashes instantly. Yet, strangely, AIDA64 and IBT act like nothing is wrong. Even at 1.75v, they stay stable while OCCT just collapses immediately.


I'm planning to delid the processor and apply liquid metal. I mean, it’s probably overkill since the temps aren't even that bad—even under the Intel Burn Test, it doesn't get scorching—but I've been using this chip for years now, so why not? A buddy of mine is lending me some Rockit 88 for the delidding process. I'm just waiting on the thermal interface material to arrive; I ordered some Grizzly CONDUCTONAUT and KRYONAUT from overseas, so I'm just playing the waiting game. It's just this weird instability across different programs that's eating at me. Up until now, it was perfectly happy at 4.0GHz with 1.200v.
