Title: Sapphire 7950 vapor - 2,5 slot
Post by: goemon888 on April 05, 2013, 07:11:50 AM
Hi! I can crossfire the 7950 vapor-x on this motherboard? It seems to fit, but 2,5 slot I want to be sure.. 2,5 slot is an issue on most motherboard? Thanks

Can't see any reason why not if they're the only cards :)

You can have a card in the 1st and 2nd x16 slot but not the 3rd x16 slot if there's a card in the 2nd slot.

I have a similar setup with the Vapor-X's and my top card gets 79C at 1950RPM while the one underneath it gets 79C at 1200RPM. Anything over 2200RPM becomes extra noisy with these cards.

Listen to this man when you are picking out your motherboards people!  Just because you have x pcie slots, does NOT mean that you are garunteed to be able to use them all at the same time.  Sometimes as soon as you populate a 2nd one, only two of the three will work.  Be sure to do your research and DO NOT assume!  All will be well in your mining ventures if you carefully pick your components!! :)  ;D
