PCIe x16 Bandwidth question

post #1 of 8
Thread Starter 
I have an ASUS P7P55D LE and inserted a GTX580 in the PCIe x16 lane 2. There is nothing in PCIe x16 lane 1. Am I still limiting my bandwidth to the slot by using lane 2? Should I have the 580 in lane 1? Reason I placed it in lane 2 was to keep the PCIe 1x lanes clear as I have a sound card in one.

It should really not matter as long as the 2nd slot is x16.

I think the second slot is X4.

What does GPUz say about link width?

Quote:
1 x PCIe 2.0 x16 (single at x16)
1 x PCI Express 2.0 x16 slot (at x4 mode, 2.5GT/s)

I'd say it is seriously limiting your video card bandwidth.

Had the case open since starting this thread. Stupidly I had just presumed this 580 was a triple slot like my DCUII 580 is, its actually just a dual slot. So I can infact move things around and get the 580 in slot one and still get my sound card in the 1x. Thanks for all the replies. Hadn't thought of using GPUz either thumb.gif

If you are not going SLI then you can put your sound card in the x4 slot as well to space it out from the graphics more

this too lol, Generally when I do a build though I only use boards with enough x16's for gpu's so this didnt cross my mind. tongue.gif

PCI-E 2.0 4x probably wouldn't result in much of a loss in performance with a single 580, but as has been mentioned there is no reason not to use the top slot for the GPU and the 3rd or 4th for your soundcard.
