Inquiries regarding AVX and Non-AVX frequencies
Inquiries regarding AVX and Non-AVX frequencies
Are the voltage needs consistent, like 4.3ghz at 1.10v for both cases, or does it require higher voltage for the same frequency? Specifically, would it be better at 4.3ghz @ 1.14v instead of 4.3ghz @ 1.10v with AVX, considering the offset function makes sense if that’s the scenario? I’m struggling to find the optimal OC and my motherboard doesn’t support disabling AVX.
Hi Phaaze88,
The AVX instruction requires higher voltage to stay stable compared to a non-AVX version at the same frequency.
This is why people often add an AVX offset of 1 or 2. For instance, at 5GHz with non-AVX and 4.9 AVX, a CPU needs 1.35V, so you apply an overclock of 5GHz at 1.35V with an AVX offset of 1.

That's the situation. The goal of the offset is stability, which has proven effective based on my tests—temperature changes are minimal at least. Without the offset, temperatures remain stable between -3, -10, or even -15, with my board handling up to -31 (probably). Working around the AVX feature would be better, as the other approach could cause excessive heat once AVX activates and the offset fails to prevent it. Thanks Rodolphe!
