Cant get SLI to work on my sysytem. Any help? :(

[nib95]

basically, I've tried so many things to get SLI running on my system with no avail.
It thinks that either a card got disconnected or says the message "please remove any non SLI cards etc etc"

I'm just not sure why it wont work.

Cards are two 7900 GT's and mobo is a DFI lanpart Expert.
Tried drivers 84.20, 84.21 and 84.25.

Bump? Anyone?

Which 2 7900GT's do you have and which DFI Lan Party do you have?

 

[nib95]

DFI Lanparty Nforce 4 SLI-DR Expert.
Both EVGA 7900 GT Extreme editions.

Did you flip all the switches on the motherboard to set the lanes to two x8?

There are 6 jumper blocks i believe next to the first pci-e 16x lane they have to be moved from the 1-2 position to the 2-3 position.

Even on the Expert?

If I'm correct enabling SLI is done through the bios on the expert. Don't think I've seen jumpers on this board for SLI. I'll have to check.

you could be right i have the dfi sli-dr and it has jumpers but i know some dfi boards do not.

Thanks for all the help guys.
Managed to sort it in the end, via settings in the BIOS.

Plus many re-installs of drivers.

I now have the Opteron running at 2.7ghz on air (30 degrees temp) and both 7900 GT's at 550/1600.
Both running cool, as I have lots of extra fans in my set up.

Getting Oblivian today or tomorrow, will post pics and benchies.
