EVGA GTX 680 SC Struck on PCIe x8 2.0

post #1 of 3
Thread Starter 
I just installed WC in my rig. As per instructions I removed the heat sink and installed EK Full Cover CSQ water block. Now when I turn on my system, GPUz shows running at PCIe 2.0 @x8.
Done load test and still shows only x8? Re seated the card several times in the slot now and reset the bios and still only x8 PCIe 2.0.
I couldn't try other ports because I need to drain the loop and install a longer pipe to the GPU. Can you guys help me understand what the problem could be?

Well for one thing you wont notice a bit of difference running at 2.0 8x speed at all. You would need a Dual GPU card to tell a difference, and even then it would only be 1 to 3 frames difference at high resolutions.

Also, most motherboards set the highest bandwidth PCIe slot to the one closest to the CPU, and thats ONLY when the other slots aren't populated.

I have thoroughly checked the slot is x16. I had been using this slot since I got the card. I haven't had any issues until I did the water cooling recently. Is it possible I have somehow damaged the card??
