ASUS Rampage 3 Extreme - Shared PCI-e Slots?

post #1 of 3
Thread Starter 
Can anyone confirm which PCI-e slots on the R3E are shared?

I am wanting to do SLI for two GTX 580s and was wondering which slots I should put them in to allow for best performance.

Thank you.

Okay, the way the R3E lane switching goes is like this. Slots 1 and 2 are tied together sort of, and 3 and 4 are tied together. If you have cards in slot 1 and 2, it will run x8/x8. If you have cards in slot 3 and slot 4 it would be x8/x8. For full x16/x16 bandwidth, you must run the GPUs in slots 1 and 3 (most common installation method I would guess) or you could do slots 1 and 4, 2 and 3, or 2 and 4.

If you were to populate 3 slots, it will go down to x16/x8/x8, and for all 4 slots x8/x8/x8/x8. Hope this helps.
