So long as you have a mobo with two PCIe slots and a second GPU, you can always flash it back.

I found the right Ultra BIOS, and it flashed successfully, the voltage as before is reporting 1.35, but the hardware is still 1.285, or 1.3 rounded... I'll have to hard mod plain and simple. Any benefit of the ultra bios over the stock bios for my gtx? Or should I just flash it back to its stock, with modded OC clocks. Stock is 576, and my card is perfect at 648 on 1.3.

I dont have second pci-e or card, but I can blind flash if it fails...

I'm trying to Vmod a 650 Ti. Another member, FXVIZI, is trying to do the same thing. Here's his thread: http://www.overclock.net/t/1350960/help-me-vmod-a-gtx-650ti
To fast forward a bit I mapped out most of the pins on the core controller. I've searched for a datasheet for the chip but I cannot find one has numbers that match with what is on this chip.

His chip has 08 EH V0K
Mine has 08 MJ E0F

Here's what I have traced out so far. Ignore the red square.
So far I have tried pencil modding the 3.193K, 15.45K, 8.74K pins without any success. One of those could still be the right pin though.
