Very Quick CF question? PCI-E Slot?

post #1 of 25
Thread Starter 
On my mobo i have 4 PCI-E Slots. 2 x16 and 2 x8.
If i run a card in the top slot and one in the very bottom slot (x16 and x8 slots are being used here) would that mean both run at x8?

Just keep a slot in between if yer on air. It doesn't matter x8 or x16.

I run in 1st and 3rd slot both x16 with a x8 in between. I wanna move the bottom card down to the 4th slot. Will it run x16 x8 or x8 x8?

I use First and third too.. Have a sound card that is PCI and have to do it that way. No problems here and my 3D Mark 06 scores are in the 18000s

I'm guessing x8/x8.

It will run x8/x8. I'm positive.
post #8 of 25
The cards will run at x8,x8. Like tsm said, it's not going to make a difference as the card will not use all of the x8 bandwidth anyways, if I am not mistaken. If it was x16,x4, then I wouldn't like it, but x16,x8 is good to go.

It won't make a difference to your senses, unless you can count in nano seconds?
