Odd thing...maybe

I thought the ASUS PGA to Slot 1 adapter automatically overwrites all voltage settings in your BIOS??? (if you already knew this to be untrue stop reading, as this will be no revelation to you):)
I have been running my celery 633@791 sHSF with the voltage set to 1.65 on the adapter. My celery will NOT even post at anything above 83mhz fsb at 1.65.
So i was fiddling with the voltage in the bios not expecting it to do anything and i set the voltage to 1.7 and the fsb to 100 and it did post but then stopped, so i changed the voltage to 1.75 (again in the bios) and it got to th windows screen. I didnt go to 1.8 coz im only using the sHSF and i know ill probably get 100 at 1.7 if i get a better HSF.
But anyway the point is i CAN set the volatge through BIOS and i didnt know this and found it very annoying to have to change the jumpers. Is this common knowledge or what !?!? BTW: its an abit BH6.

What the slocket does is fool the bios into thinking that whatever voltage it is set to is the default voltage for the cpu.

What I do with mine is to set the voltage on the slocket to 1.95v and then I can adjust the voltage from 1.3v to 2.3v in the bios. This way the bios thinks that 1.95v is the default and then you can adjust it from there with the bios adjustments...

Hmmm, that doesn't make sense (to me), i can change my voltage through my BIOS even when the adapter is set to 1.65v, why go to 1.95v?
Why does the card need to trick the BIOS into think what is set is the default voltage, when i can set the volatge higher anyway?

With most MB's the bios only allows a certain amount of voltage adjustment, as such I read about a lot of Asus MB's that only allow a max of like 1.85v. A lot of times you will need more than 1.85v. By setting the default voltage higher it allows for more voltage adjustment. You can always lower the voltage more than the bios will let you raise it.

Basically, if the bios only lets you up the voltage by 15% from the default voltage, tricking the bios into beleiving that the default voltage is 1.85v gives you the possability to up the voltage that same 15% but starting at 1.85v.
So at 1.65v default 15% more equals a max of 1.85v apx.
if you start at 1.85v 15% more equals a max of 2.10v apx.

OK, i'm with you now.
