So...
I've been trying to get my two nVidia GeForce 6800 GT (256mb) cards to work in SLI under Vista Ultimate 32bit for some time now.
Same ultimate problem no matter what I've tried, done plenty of searching for answers, with little luck:
I only get one card recognized in device manager under display adapters, thus no option to enable SLI in nVidia controll panel.
First on a MSI K8n Neo4 Ultra (nForce 4 SLI)
Ran into so many issues that I assumed something funky was wrong with the motherboard's PCIx subsystem.
Things Tried:
-Each Card individually (both worked fine)
-SLI daughtercard in each position w/both cards inserted (stayed in 8x, wouldn't switch to x16, even with only 1 card)
-Wiping drivers (no luck)
-Tried with and without SLI bridge
-Udated to latest mobo bios (no luck)
-re-seated all connections
-enabled/disabled any pertinant bios settings (SLI Spread spectrum? and others I can't remember)
After giving up the MSI mobo, I decided to pick up a DFI LanParty UT NF4 SLI-DR, one of the best nForce4 SLI boards out there.
Did a clean install of windows vista ultimate 32 bit
udated mobo bios to latest
installed latest nvidia chipset and forceware drivers
===Same symptom, no option to enable SLI!
What am I doing wrong here, or is this a fool's errand?
