8700k downclocks from 5.2 to 4.9ghz after stress tests on FPU, cache, and memory, assistance needed.
8700k downclocks from 5.2 to 4.9ghz after stress tests on FPU, cache, and memory, assistance needed.
I use AIDA64 focusing mainly on the CPU or running prime95 26.6, and it successfully overclocks to 5.2 GHz with a multiplier of 52 in the BIOS. However, during system-wide stress tests (not just CPU), the maximum clock speed falls to 4.9 GHz at full load. Could you clarify what you mean by this? Thanks!
It's probable your CPU temperature is the main issue, nearing its safety threshold and causing it to reduce performance to safeguard itself. Every CPU includes built-in protection features, regardless of whether it's Intel or AMD, and these cannot be disabled easily. By keeping temperatures below those throttling limits, you can avoid this limitation and let the CPU operate at its maximum capacity. However, your cooling system sets the boundary for how much heat it can handle.

It seems like the AVX feature is activating and reducing your CPU speed. This is typical when you leave the AVX setting enabled in BIOS as Auto...When running a system-wide test, you'll likely encounter AVX instructions too. Prime95 version 26.6 doesn't evaluate AVX at all. I don't believe this requires any concern.
