Will my lanes become x8/x4 if i get more cards?

post #1 of 4
Thread Starter 
My motherboard, the Evga x58 LE runs PCIe x16/x8/x4. I was wondering if the lanes will decrease to x8/x4 if I would add a GTS 450 for physix/folding. If I add this, I will have a total of 4 PCIe cards running. GPU, Soundcard, NIC, Physix.

Basically I want all these cards but I dont want to be running my 580 at x8

Yes, but iirc you won't really take a noticeable hit with x8. But then again, the 580 is the latest greatest thing so who knows how much data it pushes.

EDIT: Actually, it seems that what cards you put in doesn't matter. The manual says that Slot 1 is always x16, slot two is always x8, slot 3 is always x4 and slot 4 is always x8.

Which card will make it run x8? Or is it any PCIe card in will make it do that?

A graphics card by itself won't force the motherboard to run the pci-e slots at a certain speed, multiple graphics cards will and even then it varies from motherboard to motherboard.
