Setting SLI....

post #1 of 11
Thread Starter 
Alright I have another 8800 GTX headed my way....

I am on 175.16 WHQL Nvidia Drivers, both of my cards will be the EVGA types

  1. Do I need to uninstall/reinstall drivers when putting in the seccond card?
  2. Do I need to use only 1 Bridge or Two?
  3. Using EVGA preision, does OCing do both cards at the same time, or just one at a time?
  4. 750Watts is enough for SLI right?

1. uninstall and reinstall works better, ive done it both ways with my 2 cards
2. 1 bridge is fine
3. Not really sure about that, but nTune / Rivatuner will OC both cards in tandem (assuming everest isnt lying to me )
4. Should be ok, GTX's use a bit more power then G92's and mine recommend 700 for SLI

Hope i could help

Forgot one important step:
flash them to the same BIOS if they are different cards.

OK that concern though i think around during the 7800-7900 series the same brand for sli was not a problem you could at that time run a evga and BFG card in sli fine with the drivers.

Yeah Ive seen people SLI BFG and PNY cards...

But for the record: Both of the cards will be the EVGA Black PCB style cards, not sure if there is something else to that but on EVGAs site... theres no BIOS updates for the GTX's

Why? I've run half a dozen mixed sets in SLI. card brand and bios is irrelevant.
