Can't use custom voltage? A7V133

[Becks2k]

I have a 900Mhz Tbird and a A7V133

Right now its running at 9x116 and ram is at 149/150 i forget and for core voltage it's "default"

if i try doing user defined 1.85v even, it won't post at any speed

i have the newest bios i don't get why i can't use a diff core v.

Doesnt make sense, but try using the VCore jumpers instead then.

:/

if i use jumpers it works fine... ut runs fine at 9x125 1.85v i tried 9x133 for the hellof it and it crashed booting windows

why can't i change the v in the bios? :/ that sucks

Humm... Saw this figured I would put my .02 in... I have the same problem I cant change the voltage via the bios and yes I have the newest bios as well (did not work with any bios). I have the board jumpered for voltage but would like to know whats up with this???

This appears to be a known problem with the ASUS mobo.
