GTX260 Core 216 running at pci-e x1

[ddogg]

I purchased this card about a week ago and noticed my frame rates were lower than my previous card which was a HD3870. After formatting my pc, the problem still wouldn't go away. I just realized after running GPU-Z that my card is running at pci-e x1. I've tried flashing the BIOS, clearing the CMOS, re-seating the card, running at stock voltages and speed, nothing seems to work. However, my old x300 runs at pci-e x16 on this board. Has anyone else encountered this problem.

My specs:
C2D E6750 (currently at stock speed)
4GB DDR2 GSKILL
EVGA GTX 260 Core 216 Superclocked
Gigabyte P35-DS3R F13C
Rosewill 600W

Bump your NB (MCH) voltage one notch.

I tried that, still doesn't work. I played around the PCI-E frequency as well, still no luck.

I had a similar problem. I have a GA-P35-DS3L and all I had to do was update the bios for my motherboard and it was working. Maybe give EVGA a call?

Alright I'll try calling them. I'm beginning to think it might be an issue with Gigabyte's P35 boards and this card.
I looked at your post, and I have the same issues you did (audio crackling when I scroll).

is there a chipset driver for your mobo?

I had simiar issue on my old agp board when it would only run at 2x agp speeds.

Yes, it's installed.

Update your BIOS and chipset drivers.

Alright the problem seems to be solved atleast for now. I removed the card and put it in my old Dell Dimension. It ran @ x16 there. After plugging it back here it's now running at x16. I hope it doesn't revert back though. I was able to overclock my CPU and memory as well. My 3dMark score jumped from 6800 to 14300.
