SLI Issues

[josh6079]

I just got a EVGA 7800 GT N515 and I am trying to put it in SLI with my EVGA 7800 GT N518. Latest drivers have been installed, both cards are there, but when I go to the 7800GT properties to where I can enable SLI, there is no check box to click in order to enable it. All that is there is text saying,

"You must remove any graphics cards that are not compatible with NVIDIA Scalable Link Interface (SLI) technology before you can enable SLI."

I went through the walk through at slizone.com in order to set it up and it still didn't work. I was concerned about the bios's being different, but slizone.com said that as long as it is the same GPU, the bios or even vendor doesn't matter. They gave an example of pairing a BFG with a EVGA.

I'm probably missing something very simple, but if anyone might know what to do any help would be appreciated.

make sure SLI is enabled via jumpers on your mobo or through the BIOS if you have a jumperless SLI board.

Yeah, I did the SLI lane transfer through the bios on my DFI Expert nF4, it showed my bios and everything on the screen and it showed Windows loading, but when my desktop was supposed to pop up, the screen just stayed black, all I heard was the intro music.?.?.? I'll try uninstalling the 84.20 drives, doing the lane switch, then reinstalling them and see if that works.

Once again, if anyone else knows what I'm doing wrong, don't hesitate to bash/tell me.

Hmmm.... no video when u enabled SLI through the BIOS?

Thanks Matt2 for you trying to help. I unistalled the drivers, had to use a driver cleaner to make sure they were gone, then went in the bios and changed the lane transfers, reinstalled the drivers and it worked. Thanks a million for you suggestions though.

Glad to hear u got it working. Now enjoy! You wont be disappointed.

How do you change the lane transfers?

I'm having the same problems, using a DFI Lanparty eXpert and 2 x 7900 GT.
Someone please help! So I can get some Oblivion 7900 GT SLI benchmarks on the go!

Drivers are 82.40

Please! bump!

Sorry, I haven't looked at this for a while. Go into your bios and change the PCIe lane rates. I think it is under your Genie Bios section one the main list. Change it to 8, 2, 4, 8 or something like that.

Once again sorry for the wait.
