SLI PROBLEM!

[coopermckay]

My friend just got another video card for sli, both cards are by the same brand; evga. we installed them fine, and then we get a message saying to enable sli, but when we do so, we get the blue screen of death. i uninstalled the drivers, restarted, installed new drivers, and still had the same problem. I reinstalled windows, and that didn't help. I updated the bios that didn't work either. the sli bridge is connected. I don't think its a hardware problem becuase windows says: "You have an SLI capable system, enable sli to take advantage of muti gpu rendering" but then when we go to enable sli in his video card settings, blue screen of death >_< . I can't read the error becuase the computer restarts very quickly. Here is his specs:

athlon 64 3200
MSI platinum SLI
1 gb ram
EVGA 128 mb 6600 GT x2

I don't know if this is the case but since you spaced out the buying of the cards they could be running a different BIOS from one another (compatibility problem).

is he supplying enough power to the cards?

try uninstalling the current driver first, then reinstall it

I was thinking it could be the bios, he bought the first card back in december 2004, and this card a year later, december 2005. As for the power, hes got an ultra 600 watt psu, should be enough. Also , 6600 gt's don't have a power connector like 6800's. I tried uninstalling the drivers and reinstalling drivers that didn't work. How do you change the bios of a video card? Shoudln't nvidia's drivers do that?

They aren't overclocked are they.

My friend never could get his EVGA 6600GT's working properly in SLI and ended up returning them and is now running EVGA 7800GT's with no problem. His 6600GT's were ordered at the same time and were about as identical as they come.

Just for grins, try these drivers. They're pretty much the last drivers to come out before the 8x.xx series. I know they're old and beta, but give it a try, enable SLI, and tell me if it still BSODs.

im not at my friends house, ill going to call him and tell him to try the drivers when he gets home from work

 

[coopermckay]

Tried those drivers, same problem . I tried removing the bridge and that didnt work. then i tried switching the cards that didnt work either. Whats the problem >_<

I htought with the latest drivers you can mix-and-match different brands of the same chipset?
