GTS8800 640MB OC?

[Dave0w]

I am looking for ways to over clock my Point of view 8800GTS 640mb. I have been told best way is to use ATItool? i cant get this to work but the name leads me to thing it's for ATI cards? or it's my 64bit OS.

second i have been told try GFX BIOS flashing, i have no idea about this at all.

The only Bois option i have for OC'ing are below (image from MSI site)

any help would be super.
It's a second card in a soon to be updated media centre so killing the card is no problem, i am open to all ideas

The BIOS can only change CPU,system RAM and motherboard settings.

So changinf the PCI-e frequency will not change the card in the slot?

all so what about the cards BIOS flash
