yes i started the system up with a single card i did both cards one after another just incase one of my cards failed on me but they both work fine another thing the bottom slot where i inserted the second card it didnt want to latch on when i inserted the card i manually latched it in myself XD im sure thats a big no no? i dont think that would make sense though the card itself should lock in itself but it didnt when i plug them both in they light up and both fans spin during boot up another thing i noticed i went into bios and no cards were found i did a bios flash update and went into bios again to find that one of my cards were now showing it said somthing like this ( slot: PCIEX 16/8_1 type: running at X16 Native )
the other slot (SLOT: PCIEX1_2 ) says no VGA card found
