Safe voltage for 8800GT?

What's a safe voltage for a water cooled 8800GT?

I guess it's around 1.4-1.45 V. But you'll probably run into over current protection much earlier. My Gigabyte experienced it at 1.3 V. Anything above that and it would get the Vcore to 0 V after some gaming. There are some resistors you could remove from the card to go pass OVP, but that increases the chances to kill the card.

Well, it was my 1st attempt at modding and unfortunately one of the solder pads came off while trying to attach the variable resistor and I haven't been able to fix that part. So...I did a different mod where the vcore is stuck at 1.53v in the hopes of flashing the BIOS and getting a lower voltage but no luck with the flashing so now the voltage is stuck at 1.53v...I haven't tried getting into windows or anything...it boots fine though. I'm gonna point a bunch of fans at the VRMs and memory and hope that the card doesn't die.

1.53V is a lot and surely OVP will kick in at that. So even if it boots fine, it won't be stable in 3d. Is this the reference PCB?

No it's non-reference.
