Quick question about PCIe

[BLiTzKRiEG]

I am working on the main rig in my signature,

Quick question: Can I place my 7800GTX into the 2nd PCIe 16x slot and still get the machine to function and run properly? (as in with nothing in the first 16x slot).

I am wanting to move it to the second slot as to not have to have my water tubing at such an extreme bend, and saw this as a simple practical solution.

Thanks in advance!

Im going to take a good educated guess and say yes you can. The only thing I can see is that the second slot will be eletrically x8 instead of x16. But even x8 speeds is way than enough bandwidth for today games.

Second slot down to 8x? Why would it do this... I am not running SLi at the current time, and the slot is said to be another PCIe 16x slot... So if I am not running anything in the first PCIe 16x slot, and place my card in the second PCIe 16x slot, why would it only run 8x?

You should be fine. They are both physical and electrical x16s, so says [H] & DFI.

Thats what I thought... I understand about the splitting if in SLi where each runs at x8... but wasnt sure how if using a single card would make it only render at x8 even though its an x16 slot.

put it in and check with CPU-Z, current gen cards only really need 4x in single card mode before performance hits occur

I did alot of reading... it is apparently true that the second x16 slot ON ANY MOTHERBOARD is not x16.... it holds an x16 card, but will only run at a max of x8 in dual card mode... if in standard mode, it will run at x2... chalk one up to everyone's marketing department.
