SLI question.

[RetrogamerX]

On my mobo I have 3 PCI-e slots. I have my two 770's in the first 2 pci-e slots. I cant fit my sound card because the lightnings are so big. I want to know can I SLI in slots 1 and 3 without losing speed? This way I can put my sound card in the middle instead.

Your first lane runs at x16, the second x8 and the 3rd x4, so yes, you will loose speed.

the way you currently have it it is running at x8 / x8 (which is the same as PCIe 2.0 x16 / x16)

if you want to switch to 1 & 3 you will be at x8 / x4 (equiv to 2.0 x16 / x8 )

so yeah, you will be losing a bit of raw bandwidth, but it might not have very much impact in actual gaming

I guess I can live without a sound card. I can use onboard sound. It wont be DD but stereo will do

You can always get a raiser?

I did get it installed, but when I do nvidia control panel doesn't work and also the display goes to 800x400? I take the sound card out and everything works again? I don't understand?

Does anyone know why when I install my sound card the nvidia control panel doesn't work and my screen goes to 800x400? Also my second display disappears? If I take out sound card all is well again. It's weird?

Sounds like some kinda of hardware resource conflict, may be the motherboard can't handle it, needs a firmware update or one of the GPUs is slightly loose in the socket or something.

I check both gpu's. Their in. Bios is up to the latest. don't know really?

Edit: Not to worry....I'll just use the on-board sound. It's not bad on my high end mobo.

I'll just return the sound card I bought and get something else.
