PCI-E/GPU slot question

[Kalnos]

Motherboard: Asus Sabertooth P67
GPU: Gigabyte GTX 460

Hey, I'm having a small issue with my motherboard and I'm not sure if it's just a design configuration or if a pci-e slot is dead.

If I install my GPU into the first 16x pci-e slot my computer boots fine and I can obviously go into Windows, run anything, no problems. If I switch my single GPU to slot two though (runs x8 mode, according to manual), I can hear Windows start and the computer appears to boot fine, but no video and a red vga light is lit on my motherboard indicating a problem.

Is this a sign of a dead pci-e slot, some bios configuration, or is this x8 slot solely meant for a second video card in SLI?

Thanks for any help.

Might be either a BIOs config issue, you didn't plug in the power/GPU correctly, or dead PCI-E slot. Generally PCI-E slots are not meant specifically for a certain type of hardware

I don't think I entirely agree with you Danny. I know on my OLD Asus S775 board the card would work only in the first slot, but the second PCIe slot ran my RAID controller just fine. Have you tried googling the problem?

I believe that the second slot is meant for SLI/CF. In many motherboards, the first PCI-E x16 slot (from the top) is designed to serve as the primary slot.

Yeah, I'm thinking maybe it's solely for SLI since it still boots into windows. If not, then I guess it's a dead pci-e slot.
