Which PCIE Slot for single card, can I use either?

Recommended Posts

I'm almost ready putting my system together. I have replaced the stock chipset cooler with the Evercool VC-RE. Everything is installed properly. When I tried to put a 7900gtx it was a little to close to the VC-RE for comfort infact I think some of the card sticking out slid between the fins on the VC-RE. Being this is the most expensive video card I've ever owned and probably most expensive PC I've ever had I really did not want to risk it and put the video card in PCIE slot 2 near the bottom.

 

Will I have any problem running on this slot or will the system not boot unless it sees a card in PCIE slot #2, also my first PCIE system.

 

Thank you in advance.

Only thing you have to do is to move the jumpers located between PCI-E slots to the other position (SLI-mode). This way you'll have 8x for PCI-E 4.

What if I don't? Is 16x only available on PCIe #1? It says they both are 16x capable slots. I don't want to sacrifice performance but I don't understand how everyone recomends the Evercool VC-RE and yet and I can't the card in the 1st PCIe slot. I could not have mounted it wrong as it uses the mounting holes from the original unless people bend fins and risk the fan rubbing against the PC board of the video card? I just want the best performance possible.

If you don't the slot will remain at x2 speeds, and yes x16 is only available on PCIe 1. They are both x16 capable in that the physical size allows for x16 cards. I think you can probably still use the first slot if you want, its going to be close but just watch it. Otherwise you'll need to change the jumpers so PCIe 2 runs at x8, which is more than fast enough for your card.
