Flashing Cards

post #1 of 9
Thread Starter 
So in my folding rig i have a 9600GSO and a 8800GS (one i bought, one i won from OCN) when i have friends over id like for them to play on my folding rig, seeing that the 8800GS and the 9600GSO are the same thing would it be possible to flash one of them so i could do SLI? Also what would be the risks of failure? Thanks and rep + *JaKe*

You would first need to find either the 9600GSO bios or 8800GS bios. And if you don't know what you're doing your chances of bricking your card are a lot higher.

go to Google and type in graphic card bios and theres some site that has pages of down loadable bio's from different cards and brands. just as marin said worst comes to worse you brick a card. i saw go for it!!!

1. Find compatible bios
2. Flash it.
3. Throw holy water onto card. Don't worry, its holy.
4. ???
5. Profit !!


Don't do it... you will mess up your cards pretty bad.

Well to put it simply. When the card is bricked you need to perform an exorcism to unbrick it, thus holy water.

@OP, here's how I would do it

Since you have 2 cards, it's 10 times easier that if you have only one because of one simple reason: if you make a bad flash, you can always boot from the second card and flash the one with the bad flash with the stock BIOS. With that in mind, here are a few steps:
  • find the one with the lowest clocks; let's say you have the A card and the B card, and the B has the lower clocks. We'll call B the main card.
  • make BIOS backups of both cards calling them Abackup and Bbackup; here's a great guide on OCN on how to flash BIOSes; you will be using a soft called nvflash to update the BIOSes
  • now B is the main card due to the lower clocks; take the Bbackup BIOS, make a copy named Bnewbios, it will have the extension .rom like Bnewbios.rom
  • very important - now is the fun part - shut down and remove the B card from the computer; place the A card on the uppermost PCIe slot; start and enter the BIOS, set the BIOS to boot from the uppermost PEG PCIe (called usually PCIe0 or PEG0) - check the manual if unsure. Restart.
  • now you'll be using nvflash like in this guide: from the windows make/insert a bootable floppy, copy onto it the nvflash soft and the BIOS called Bnewbios.rom; restart and boot from the floppy
  • use this command in the command prompt: nvflash -4 -5 -6 Bnewbios.rom
  • now the BIOS from the B card is updated on the A card - two things can happen:
  1. all is ok, you'll have 2 B cards
  2. the A card with B bios won't boot; then you'll have to make a blind flash; you can shutdown, remove the A card, insert the B card, boot in Windows and put on the floppy the Abackup.rom BIOS - next you'll swap back in the A card with the bad flash, and make a blind flash with the new BIOS: wait for it to boot from the floppy and after it doesn't make any noise type nvflash -4 -5 -6 abackup.rom
In case all went fine with the flash, you have 2 identical cards to put in SLI; if it didn't you'll be back to square 1 with an A and a B card; in the latter case you can search on the web for BIOSes that are likely to work on both cards, thus you'll have a Cnewbios.rom to flash on both of them.

Hope something works as they're 2 identical cards only with different names, the chance of a bad flash is real slim.
