I've been having an odd performance issue with my rig, pretty much ever since I got it. If SLI is enabled when I start the machine, performance in all games is downright terrible - something like 1/4 of what a single card can manage. If SLI is disabled, or if I disable it then re-enable it, everything works normally. System as follows:
Asus A8N32-SLI Premium
Opteron 185
2GB Corsair DDR400
2x8800GTS 640MB
Windows XP SP2
It's not a huge problem but it is a pain in the backside, and I'm at my wits end trying to find the cause. I've done all the usual things i.e. latest BIOS, drivers, no overclocking etc. to no avail. Any ideas?
