I'm about to do a crazy thing!

well, I've got an ASUS 8800gt 512MB GDDR3... and here on the GPU BIOS database I found the ASUS 9800GT 512MB GDDR3 Hybrid Power BIOS, which allows voltage increments of up to 1.2v!!!

My 8800gt is already BIOS volt-modded to 1.1v which increased my OC significantly.

But as 8800gt and 9800gt are basically the same card, I was thinking of flashing it to a 9800gt with 1.2v! This should make it able to overclock even higher!

Does this sound too crazy?

I know they're the same card, but I'm just not too sure about this Hybrid power thing... plus, the BIOS i downloaded is for the 55nm 9800GT. The 8800gt is 65nm...

This isn't gonna work, is it? And even then, would 1.2v be too high for the 8800gt?

Because of the die shrink? 65nm -> 55nm?

Will it fry it? How about 1.15v then?

Would this flash be possible? Or not really?

Well, so long as you have 2 pcix slots and a backup card there is always recovery from a bad bios flash... Just backup the old one...

I don't think it will even post though. The bios for the 9000 series has surely goen through substantial changes.

Well, Im not particulary well versed in Nvidia flashing tools.. But with atitool it is as simple as 1 and 0.

Provided the card in slot 0 (the top one) works (that is you can actually see the screen ) you simlpy boot to dos, use atiflash tool and aim teh flash at slot 1 (where the dead card sits) instead of the default 0. The syntax for doing this and the program required someone else will have to point you towards. I have not played with an nvidia card this extensievly in years.
