Rampage III Extreme 480gtx not recognized

post #1 of 4
Thread Starter 
OK here is my situation. I have the Asus Rampage III Extreme motherboard with dual 480 gtx graphics cards. If I put either of the 2 cards into pcie slot 1, they will not get recognized, meaning my monitor will not get a picture and just cycles saying no input detected. If I try either of the cards in pcie slot 2, 3 or 4, they are recognized fine. Here is the kicker, I inserted a different pcie graphics (low end ATI) card into pcie slot 1 and it works fine.

The setup with the 480gtx graphics cards was working a few weeks ago, then I had a cpu waterblock issue and had to take everything apart.

Any suggestions?

Thanks.

When you fire up the board with the 480 in slot 1, do any diagnostic LEDs light up? (the LEDs near the 24-pin connector)

Do you have power going into the 4-pin molex on the mobo for the PCI-E slots?

Have you tried clearing CMOS via the switch on the backplane?

Do you get the same results with the second BIOS?

Are you on the latest BIOS?

What was the nature of your waterblock problem?

...sorry for all the questions, but these boards have TONS of features which means there are TONS of variables that could be tough to troubleshoot. It might help if you fill out your sig rig info.

Hmm, I did not notice, I will look.

When everything was working a few weeks ago I did not and I do not have them connected now.

Have you tried clearing CMOS via the switch on the backplane?

Yes and it work once, but now it is not working.

Do you get the same results with the second BIOS?

I have not tried the second bios...I will try that tonight.

Are you on the latest BIOS?

I am running 1005.

What was the nature of your waterblock problem?

There was no water flow going through the block...I replaced the block with a new one.

Does 1005 bios support 990X? It's not on Asus cpu support list.
