I have the MP3,1, where only slots 1 and 2 are PCIe ver. 2.0. In these two slots I have installed an Accelsior card, and a GTX680 graphics card.

Wondering if all is OK, I checked the interface speed on the GTX card, and saw it was "only" 2.5GB/s, where I thought it should be 5.0GB/s. So, of course I wondered what could be going on :confused:

I have the Accelsior card in slot 1 and the GTX card in slot 2, so I swapped them around, and now nothing worked correctly. I do not usually have a boot screen (due to the GTX card), but nothing came up, not even after waiting for a few minutes.

What I noticed was that usually (with the Accelsior card in slot 1), the card flashes a few times during boot, but not when the card is in slot 2.

When I switched it back to "normal" it all works. What can be going on?
