what should my core voltage be

[arden]

kt7a mb,1200tb,I set voltage to auto which says 1.75 in bios,mbm says it is 1.8-1.81 is this right for my proc.Thought I seen somewhere this proc was 1.8 but cain't remember where.

That's something you have to be aware of, voltage differences from what you set in SOFT MENUIII & it's usually higher in the Health Menu. The old faithful TBirds usually were set at 1.75V so adjust till you get the proper hang of it. My KT7A-RAID added .1V to my VCore & 3.3V rail.

from what I have seen, voltage always shows .5V higher once you boot to the OS...keep this in mind when raising your voltage...

BIOS > OS

1.75 = 1.825

.5V increase when you boot to the OS?!

VCore 1.75V
VCore +.5V
---------------
VCore 2.25V

That's one hell of a change

sorry, I should have said .05, and my math was wrong...too early in the morning!

I don't know how accurate it is, but if I set my BIOS at 1.7 (like it is now), and boot into XP, every monitoring program I use will show 1.75...

It differs from MoBo to MoBo. Some give .05V & some more. The MoBo manufacturer adds more voltage to increase stability.

Thanks for the info,was starting to wonder why when I man. set to 1.75 mbm allways reports 1.8.
