Hello,
I had to move my graphics card from top PCIe 16x to the next PCIe 16x and it seemed to be doing fine until I tried to benchmark it or play a game. My whole screen go wack and the whole computer fezzes. I've tried it in the 16x (half pin slots) and it ran fine yet I would want it to be in a true 16x full pin slot. I've never used this slot before. Any idea why this would be happening? Maybe I have to config something in BIO's?

I've looked more into this and I've notice the Bus type is 3.0 x16 and its running at 2.0 x16 (in both slots where I was thinking it was running 2.0 only when changing to the lower slot.

Mobo = SaberTooth 990FX r2.0
Grahpic card = Sapphire 280x 3G Tri Toxic

why did you move the card?


see the little "?" next to the bus interface


click on it and run the benchmark


does the pcie speed go up?



if it's running at 2.0 x16 then that is way more than good enough for a little 280x
