Horrible VDroop problems

Ratman43 · 21 Jul 2022 at 00:13

Just overclocked my Asus P5K mobo with a quad core Q6600 from 9x267 to 9x333.
My bios is the latest 1201 bios but modded to enable AHCI on all sata ports.
VDrop from bios to idle is about 0.7, so I set bios voltage to 1.425 and get a vcore of 1.35.
That’s fine and good but when I run Prime95 the vdroop takes me down to 1.27 and sometimes even 1.22.
LLC is enabled and I’m not comfortable setting my BIOS voltage past 1.45 or 1.475, should I try out one of those pencil mods where you put graphite on a resistor?
Those don’t seem very safe but people claim they work.
Thanks for any replies!

Forgot to mention my VID is 1.2125
And running prime95 for around 10 minutes doesn’t get me any errors despite the crazy low voltage

At 1.45 bios voltage running Prime95 I’m getting 1.288, 1.264, and a minimum of 1.256 vcore

And my multiplier keeps dropping to x6 despite intel speed step being off

Setting CPU ratio to auto and leaving speed step on disabled seems to keep it at x9, before it was set to 9 but it being manual causes the speed step option to disappear.
Testing with and without LLC seems to only give an additional 0.08 vcore which is nothing

This forum post seems to have a lot of the issues I’ve been experiencing: https://forums.extremeoverclocking.com/showthread.php?t=290266
Really bad VDroop and LLC not working for ****.
Will try downgrading my BIOS before doing a pencil mod.
