I have what appear to be two identical GeForce FX 5500s but only one (the one with the fan) works in my Intel 440EX motherboard. The other will cause the system to emit an error beep that there is no video connected.

Using the same card in a Socket 775 shows that it works just fine.

My 440EX also rejects a working FX 5500 for PCI.

Does anyone know what might cause only one of these seemingly identical cards to not work? I can only guess it's something with the cards BIOS but it's an interesting thing to see.

I retested these and both cards report an identical BIOS version 4.34.20.69.04 at startup. So this doesn't seen to be the issue.

I removed the heatsinks and snapped some photos of the GPU and found that the part numbers were slightly different. I wonder if this is somehow related.

The chip labeled with QA6035.1 0508B1 also has a manufacturing date on the back of week 5 of 05 and this is the card that works in the 440EX. The other one labeled GK3697.1T 0544B1 as a manufacturing date of week 12 of 05 and is the one which doesn't work in the 440EX but does work in socket 775.

I also have a third card here to add as a sample. It does not work at all. I suspect that it's actually dead and not just pretending to be like the other one.

All that I can tell from the labels is that these cards were made by XFX.
