[SOLVED] AVX/AVX512 settings on z590 boards and i7 11700k

[vladakv]

Hello.

In order to prevent overvolting using avx apps, I'd like to know what settings should I use in bios? The main problem is, when I run apps what use avx, voltage [VCore] spikes up to 1.52V. When I use avx and avx512 with negative offset to -2, max voltage load is 1.350V, which is ok.

So, in my bios I have another avx options - ''AVX voltage guardband scale''. What is it? Can I change it to some value?

Are there other ways to drop down avx/avx512 voltages?

i keep AVX @ -2,
AVX 512 @ -4.

but i have a manual overclock of 5.2GHz all cores and at 5.2GHz v1.305.
even with a manual lower voltage set, with AVX set to 0 offset usage would spike temps to >80°C which i don't like to see.
my current setup keep temps <75°C when stressing with AVX.

I dont oc, just using Vcore negative offset -0.080. Can I apply this avx avx512 settings?

you could use any offset or none at all if you desire.
if you're happy with current temperatures and stressing with them both at 0 doesn't cause you to crash or throttle, i'd just leave it 0.
