post #1 of 19
Thread Starter 
Hi guys.. just got my other 580 today.. for some reason sli is not detected in my computer... i tried driver sweeper then reinstalled the latest driver.. but still no luck... it showed that theres two card's being installed but I couldnt find any options in my nvidia control panel to enable sli... and yes both cards are bridged...

any idea what's going on?? might it be a bad bridge??

You need a SLI mother board board to SLI. Yours isnt a SLI board (even thought i has 2x PCI-X x16)

You can use the SLI hack to enable SLI..

Heres a guide:

All P67 boards have SLI

ensure the proper updated drivers are installed

make sure the bridge is in full contact

make sure both cards are plugged in fully

and make sure the bios's on your cards aren't modded, make sure their on stock or modded from stock

I couldn't enable SLI once and I did my head in trying to find out why I had no SLI option because I flashed a modded voltage bios onto one of my cards that Nvidia control panel didn't like so it denied me the SLI option.

after using a correct bios, SLI option was available again.

For me i had to go to the device manger select uninstall on one card and reinstall and it worked..

Every other tim i SLI'ed

(9500gt, 8800gtx, 9800gx2, gtx 260) i didnt have to do it..

Weird huh..

Won't matter.

After installing the second card, you need to make sure you reinstall the drivers so they can detect the SLI configuration.
That should fix your not detected SLI issue.

Doesn't really matter.
I'm usually using the outside one. A friend of mine usually use the inside one.
