If GPU-Z still reports the card running @ x1 - then it it looks like you will have to adjust some jumpers on your motherboard to acheive the x16 /x4 config:

P965-S Jumper settings

If I may add, you may need to set your bios as PEG2 being the default during the time you have the top card removed. If you just remove the top card and don't adjust the bios, you might not get a picture at all. Just a caution, motherboards are different.

Good point. I did try to download the BIOS manual for that board but it was literally crawling down @ sub dial-up speeds, so I didn't get a chance to look through the available settings.

At any rate, good luck w1rex

I have an creative x-fi installed which I have disabled. The on board realtek (mb is an asus ph67) shows audio input to speakers in control panel but no sound at jacks (front or rear). Does the presence of the Creative SC disable the onboard audio?
