Best way to populate pci-e lanes p67-ud7

post #1 of 3
Thread Starter 
What is the best way to populate the pci lanes on a p67-ud7? There are probably different answers depending on gpu water loops, temps/airflow etc. but I am asking about my personal setup. What do you feel is the best way to populate?

I currently have my pci lanes populated as follows (from closest to cpu moving down):

pci-e 1x: empty
pci-e 16x: gtx 470 (stock cooler double slot)
pci-e 16x: blocked by gpu1
pci-e 16x: empty
pci: sound card
pci-e 16x: gtx 470
pci: blocked by gpu2

My other question is: Are all the pci-e lanes 16x except the 1x slot up top?

I know I could take out my cards and look at the lanes themselfs to see how much bandwith they have, but I just re did my cable management yesterday and really dont want to mess with it again(unless there is a better way to populate my slots).

Thanks

Run GPU-z and look at the bus interface info on the main tab.

If it's at x16 2.0 then your all set.

The first and third slot run at x16 if both slots are populated, if you populate the fourth slot with anything, it will drop all lanes to x8. If you have populated the first and fourth both will run at x8 (i think)
