PCI-E 8x BUS

Xer0x · 01-14-2006, 11:33 AM

I have geforce 6600GT, pci-e 16x, or so it the motherboard manufacturer says. I go into the nvidia display options, and it reports it's only running pci-e 8x, instead of 16x. I feel I am losing performance, and it should have more bandwidth than that.

^First mobo

I only use 1 card, so it's not SLi running two in 8x. But the BUS speed isn't what it should be supposedly.

You might have the motherboard set to SLi mode. Even if there is only one card pluged in, it will still split the PCI-e x16 to 2x PCI-e x8.
Check the small adapter card between the two PCI-e slots is set to single or standard mode, and not SLi.

by the card do you mean teh card that's at the base at a 45 degree angle?

hah, problem resolved.

Apparently I had that card that's goes in between the 2 sli cards, set to SLi mode when I only have 1 card. I just flipped the card around and that's all folks.
