P55a-UD3 PCI-E Slot question Tags: Motherboards SLI Pci Express Last response: October 30, 2010 12:23 PM in Motherboards Share cammo2066 October 30, 2010 11:13:43 AM Thinking of crossfiring 2 x 6850's, since I've learnt that a x4 2.0 PCI-E SLI/Xfire is of hardly any noticeable disadvantage. I just want to clarify something since the manual isn't clear. On my P55a-UD3 there are 2 PCI-E slots. x16 (2.0) and a x4 (???) Can someone tell me whether or not the x4 slot conforms to 2.0 standard? ------ If it doesn't I will probably reconsider xfiring.

(20 minutes because I have to re-arrange cables etc) For those wondering the x4 slot, IS 2.0!!! http://i288.photobucket.com/albums/ll198/DeathFrogg/20....
