Have you tried un OCing the P3 in the AOpen system? Using less RAM. Im trying to think of anything really.

Sometimes on these older computer part's, I've had to have the card installed at a certain angle for it to even get detected.

I've had that problem with other GPUs and cards too, but this one works fine at any angle as far as I can tell.

I reset everything to default settings and it still will not boot. I've tested the card with 32MB-1.5GB of ram before so it should work just fine from what I can tell.

I wouldn't recommend running the 5900xt on anything older then a KT266. Don't get me wrong, the card should work with that motherboard, but even if the machine posts, you might have driver issues.

Well I pulled the card from working at 2X AGP mode on a old slot 1 Techram P6Pro-A+ mobo, without any issues at all, so in theory it should be just fine with this newer board.

Damn thats crazy. I had this issue before with a GT 430. It works just fine in all my systems, but one computer will not boot with it in it.

Like I said - in theory it whould work, but running AGP 4x/8x cards in old AGP 2x/4x boards is sometimes more trouble then it's worth. It think it all boils down to how much power the AGP slot on the board can deliver (even if the card itself has a dedicated power connector) - since stuff like the FX5200 usually runs fine, but higher-end cards like fast FX5700 with the full 128bit bus and fast DDR memory have issues.

I've seen people run a 6800 in P3 machines, but aside from possible hardware incompatibility there's also driver issues to contend with - especially on earlier VIA chipsets where some versions of forceware work fine, while others BSOD, artefact or black screen due to incompatibility with VIA chipsets.

From experience I've concluded that if you want a reliable-painless and fast socket 370 rig, get a Geforce 4 Ti card. A ti 4200 is not that hard to find, nor is it expensive, it's perfectly compatible with older motherboards (the AGP 4x version of the card -the 4x/8x version has issues) and it's fast enough to drive ALL games you might play on a P3 rig at 1600x1200 with anti-aliasing.

At one point I had a Gigabyte FX5700 in my P3 rig, (i815 / 1.4Ghz tualatin) but due to driver incompatibility with some games (black screen issue in DK2 and Soul Reaver to name a few) I switched back to a Ti 4200 and forceware 41.09

An FX card is best suited for faster P4 and Athlon XP machines - witch both run win98 just fine.

Well I made a few modifications, by replacing the ram with three 512mb sticks at 133mhz, and updating the bios to the newest one available.

Sadly neither of these things effected the FX 5900XT and the ram is too unstable to allow the cpu to run overclocked on by increasing the fbs so it can only run at stock speeds now.

At this point I've decided to simply move the FX 5900XT back to it's original Pentium 4 based rig and search for another card to replace it that works with this board. I had a Geforce4 4800 Ti, but it's been broken for years so I can only spare a Nvidia TNT 2 to replace it for now.

Thanks for the advice everyone, If I ever find a fix later, I'll post it here.
