I increased my 9700k to 4.8ghz with a voltage of 1.335 volts and attempted to push it to 4.9ghz. It worked well without overheating, staying under 84 degrees, but crashed when I tried running a test with avx2 enabled. After resetting the overclock to 4.8ghz, it now fails with avx2 when I didn’t expect it to. I’m using Intel Extreme Tuning Utility for this. Can you help me understand how to fix this or which apps use avx2?

If your CPU operates smoothly at 4.9Ghz with the offset enabled when an AVX instruction is present, it will slow down to 4.7Ghz. Using AVX512 would reduce it further to 4.6 or 4.5GHz. AVX puts more strain on the processor, likely causing instability due to insufficient power supply, leading to crashes. My 8700k runs at 5.1Ghz without issues and remains stable, so I don’t need AVX offset. Reaching 5.2Ghz demands excessive voltage, making it impractical.

In the BIOS, adjust the AVX offset to -2 and AVX512 to -3 or -4.

What effect will it have? Will it resolve the issue? Are there any other changes?
