So I finally got my board but now SLI doesn't work :( (Asus EFI + Windows 7 SP1 SLI)

post #1 of 38
Thread Starter 
Got both cards under water and yeah... After spending a good 6 hours trying to get windows installed off a disk I finally gave up. I pulled my laptop HDD and use that to install Windows from an ISO onto the new HDD.

However my troubles did not end there

I can not get SLI to become an option. I've tried reinstalled windows twice now, used three different drivers, disabled, enabled, driver sweeper, and whatever else I could think of.



I'm not sure what is going on. When I put my 9800GT in it also shows up, but I removed it to remove it from the equation.

The only thing I can think of is installing windows with both cards in is causing a problem. Can that cause it? I'll try removing one and reinstalling again tomorrow, its late and I'm tired.

Anyone have any other suggestions I can try out?


(Solved)

Yeah, I know a lot of that doesn't make sense (lol)... But in the end I got it all working, I don't need to use my laptop HHD as the boot drive either.

God, that took me from 2pm yesterday, until 6am this morning, slept until 10:30am, and finished at 7:30pm...

Too bad I wasn't getting paid by the hour




+1 all around thanks for the support guys.

Installing windows w/one card only is worth a try. Make sure you let windows do it's thing w/installing drivers ... even let it download from windows update and install if it wants to ... then when all that's done, restart, and install forceware using clean install. Then shut down, install 2nd card, reinstall drivers over top of the current ones, restart, and hopefully SLi will enable.

I'd also check and make sure your board came w/the latest bios version installed and if not obviously flash to newest.

Weird. I actually just installed my SSD w/a clean windows install and didn't have any issues with both of my cards plugged in the entire time. I agree with brett about checking for updated BIOS revisions.

Bios is updated to the latest version, it came that way.

I can't sleep without trying another reinstall

i had the same problem before its related to the nvidia drives try GeForce/ION Driver v266.58 WHQL or 260.99 or if these don't work try installing the same drives again (2 time try this with the latest drives).

Have you tried swapping the SLI bridge to another one?
Could be that the bridge is DOA.

This was a no go, it made me restart a lot and windows installed the chipset drivers I had already installed... twice..

Still showing two cards, still no SLI option.

I have tried a second SLI bridge (the B3 board that came today had another so I tried that one).

Are you using two monitors?
Try to disconnect the monitor connected to the second GPU.
