1. What was the old one's model that you were using and the new one that you upgraded to?

2. Are you using the same PCIe lane?

3. Are you reading the x8 speed from GPU-Z or within the BIOS?

Reseat the GPU. Then proceed to clear the CMOS. See if that solves your problem.

Download GPUz

Open GPUz

Look to the middle right hand side.

See that ? mark.

Now click it and let the test run.

Your new graphic card clocks down as a power saving mode.

Does the x16 come back now?

I use the PCIe 1 and PCIe 2b for my two cards. So no problem there.

is your vga card take 3 slots as mine? if you use pcie 1 and 2b are they going to be extremely hot?i try this today, i put ati 6950 to the 2b slot( give the power and let it run free didn't connect any screen) and play skyrim for about 2 hour and gtx 680 gets near to 70 degree Celsius. room temperature about 18 degree. in summer it might go up to 90?
