BIOS vcore is different than cpuz! HELP - Page 2

post #11 of 19
Dunno if this helps but
On my motherboard there is no such thing as extreme, high, ultra high, LLC
just auto, enable, or disable.
enable causes my vcore to always be lower than bios
1.318v set in bios
1.304 in OS idle
1.312v in OS prime load

Those settings are used on all Asus SB motherboards, your mobo is x58 so I think that's why it's different tongue.gif

well seeing as how there are 3 potential LLC settings for each. the 3 x58 settings probably correspond to the SB settings

Can you post your OC settings?

Edit: Do you have the latest CPU-Z?

Well its not underload and it goes up
In idle cpuz shows 1.07v but like I said when prime95 kicks in the v goes up to 1.351-1.40

Probably has it on auto, which is then auto setting a very high LLC level. That's the only thing that can cause v to rise under load...it inherently wants to drop.

oh and btw, im using offset mode to set the vcore... cuz my mobo doesnt have manual setting vcore =/

There are 6 settings on SB boards not 3 - Auto, Regular (disable), Medium (25%), High (50%), Ultra High (75%), Extreme (100%).

doh.gif Yea that would explain a lot.

Offset will cause your voltage to be set dynamically, so when idling you'd have normal intel set volts running through the chip (1.07 as you said), then when under load your BIOS set voltage will kick in (in this case it happens to be 1.35v, once vdroop is accounted for).

If you've disabled LLC and you're getting 1.35-1.4v under load that means your BIOS set voltage must be very big! (because there must be significant vdroop with no LLC and yet you still mange to hit 1.35v under load).

Best thing to do is start again.
- Clear CMOS.
- Set your multiplier to 45.
- Bump your offest voltage up by a couple of notches only using the "+" key on your keyboard (2 or 3 times).
- Set LLC to High to reduce the vdroop.
- Test, see what your voltage is under load, see if it's stable with Prime.

- If stable, reduce offset voltage. If not, then go up by another notch.

I'll try to find a guide that will explain things more comprehensively as there are other settings you'll have to change (particularly in the Digi+ VRM section)

Are you saying that if LLC is disabled, then the difference between the BIOS and OS voltage should be very big?

I've been overclocking recently and was wondering why my VCORE is so much lower than my BIOS voltage setting (with LLC disabled). This would definitely explain why.

Underload, yes. Vcore will be less than what is set in the bios due to vdroop.
