two GTX280's
Hello, I have installed 2 gtx280's in my I7 box and it will boot but hangs until I removed the second 280. If anyone may have some ideas I would appreciate their help. System is brand new, I built a I7, 6gigs 1600mhz OCR on a EX58-UD3R. System case is loaded with fans, 2 Raptor 150's and 1 wd 1TB drive. Works great, clock at 4.0 ghz on all 4 cores and not one glitch after a 48 hour intense burn-in. As long as only one 280 is installed its fine. Install the second SLI'd and boots past post to drive discovery and hangs???? Thanks so much in advance.
Regards, J |

Re: two GTX280's
The 280 doesn't have a light on the back to indicate a power failure like the 295 does it? That would tell you right away.
Try swapping out the cards and see if it boots with the secondary card in the primary slot all by itself. That will at least let you know the card is good. |
