yes, the voltage has to be tweaked with the FSB.

like a few minutes ago, I was testing 458, and I had to get 1.145 volts.
but thats really pushing it, cause 1.150 volts almost always equals a quick freeze of the OS.

I tried to see if I could bypass this freeze, by booting at 1.110 volts, then adjusting the VR to 1.150 volts and higher, but that doesnt seem to help at all.

I can try some 3D but I have 1 problem.

1. I have a block on my southbridge that makes my 8800GTX impossible to use, since the block is too tall, for the card to get into the PCIE slot securely, and it blocks the lowest two, so those arent a option, and I really dont want to rebuild my loop at the moment, as I am more anxious to try the quad core overclocking, then I was to mess with my 8800GTX.

sooo...
the card you see in my pic of the voltage... is a X850XT PE.
not a bad card in itself I know, but not too interesting in 3dmark on vista
vistas just slow...

so, if you want them, I will give them a shot, but dont be surprised if the numbers are low.

its vista.... what can I say? haha...
