for older cards you have to move strap resistors

Incorrect, see my second edit a couple of posts above.

I think you're on to something.... no matter what I change it to, it always goes to Device ID 0329. I don't suppose you would know which are the hardware strap IDs? I can reference my FX5200, but I wouldn't know where to look

ok
i was playing yesterday with fx5200 bios using NiBitor,
changed id to 5200 Ultra, have 5200 Ultra installed on board
but it is still detecting as a regular 5200

what i doing wrong?

On these older cards you will have to physically change the strap id resistors on the back side of the GPU. You'll have to reference a actual 5200 ultra to see how the resistors should be set up.

Well, if anyone has that info, I'd appreciate it (Quadro FX500 to FX5200). RivaTuner also works in the meantime.

Here's a pic of the back of the FX500:

Does anyone know how to mod the Quadro4 NVS200 to a GeForce 4 MX440?

Rivatuner does it partially but has "Use ROM straps for PCI DeviceID programming" greyed out... So it only does a very soft mod which does not fool the driver and performance is much lower than it should be.

The only thing I could find was from this article from 20 years ago:

Did not find any Quadro FX1100 to FX5700 /5700U straps.

Hello

trying to change straps for fx5200 using nvflash and it did not work.

second value is out of range. if i remove one digit from second value nvflash accept and doing reflash but it's going wrong and card does not work anymore.
