Another opinion please

From memory when I had a dual PIII 600mhz slot style server a few years ago. They were available, but uncommon.

As they say though, curiosity!

Btw, PCI-E 2.0 x 16 is backward compatible with PCI-E 1.0 x 16

I have an unconfirmed report that my 9600gt won't fly in that slot. I'll have a look at that too, i guess.

EggXpert - Asus P5Q Pro won't POST

well, we tried. I've some time trying to figure out why the video card won't work. The answer is Asus did not make the PCI-e 2.0 backward compatable. I've found it in a couple of places-here is the latest:

"The 8600 series won't work on the P5Q series. Reading on another forum that talked about the board, someone else was having that problem. The board is lacking PCI-E 1.1 support. Though the board has PCI-E 2.0, which is suppose to be backwards compatible with 1.1; ASUS left it out..somehow. I was frustrated myself having a XFX 8600GT XXX 256mb card that works perfectly in other machines, but put it on a P5Q board...forget it. I was only able to determine that it was the board, and not the card by testing a ASUS 9600GT card on the board, which has PCI-E 2.0 support, that I borrowed. I was testing on P5Q Deluxe, but it the same chipset on the P5Q Pro.

So, the only thing to do is to ditch you 8600gt and get a newer card with PCI-E 2.0 support. I just ordered an ASUS 4850 from newegg last night. I know it sucks to shell out more money, if you don't have it, on a new video card when you know perfectly well that it works great. But, that the solution... I did for a moment get my 8600gt working when I updated the BIOS to 1306, then swapped the 9600gt out and put in my 8600gt in for moment; but after I turned off the computer and tried turn it back on...nothing.

I hope this helps, b/c I was in the exact position you were for a few weeks now, trying to figure out what the hell is going on. I even RMA'd the board and swapped out RAM and CPU, just to figure out it was the board and no PCI Express 1.1 support. "
