So I just put together a new system. It worked flawlessly - until I tried to enable SLI. Now it has problems. I have installed 191.07 for the graphics cards, as well as SLI update v2. All other drivers for everything are installed and up to date. Here are the specs:
Intel Core i7 920 2.66GHz
EVGA E760 Classified
2 EVGA GTX 275's
6 x 2GB 1600 Corsair XMS3
BFG EX-1200 PSU
2 1TB Western Digital Caviar Blacks
LiteOn Bluray drive
Sony DVD Burner
I think I've limited it down to one of the graphics cards:
- If the problem card is plugged into the top slot, I get a black screen after Vista's loading screen. This is regardless of whether the second card is plugged in or not.
- BSoD if both cards are plugged in and have the SLI bridge
- Freezes immediately after log in with both cards in without the SLI bridge
- I've tried switching the 6 pin cables, as well as putting another PCI-E power cable in and trying that.
- With the working card only - No problems at all. I'm using it to type this message right now, and I've been playing Unreal Tournament 3 without any issues.
Here's what else I have done which haven't changed anything and have the exact same results as above:
- Cleared CMOS
- Put the bios back to default
- Swapping the PSU for an Ultra X3 1000w, as well as a Corsair HX-1000 - no change. I borrowed both PSUs from friends and those PSUs are used with other systems and are in good working order. One powers a Core 2 Quad 9650 (OC'ed) and has two GTX 295's. The other is powering a Core 2 Quad 9550 with two 9800 GX2's. I'm pretty dang sure my PSU isn't the problem.
- Checked Memory with memtest - it all good. Windows 7 also checked it - showed up as good again.
Can anyone think of anything else to try before I contact EVGA? Its not a problem to RMA it, but I know its out of stock on NewEgg... not sure about EVGA.
