Recently I have bought very nice Xpertvision Geforce 4 MX440 8x 128MB for my Win98 PC. Build quality is very nice, the passive cooling is very pleasant for my ears and the video output is super sharp. The reference card from Nvidia is clocked at 275 MHz (GPU) and 500 MHz (memory) and even though my card has full speed GPU according to those specs, the memory is underclocked to disappointing 300 MHz. Tried to overclock it higher but couldn't get past 325 MHz - not surprising considering the memory chips are 7,5 ns.
I wonder, would it be possible to buy some DDR RAM module with sufficiently fast and compatible memory chips, salvage them and solder them on the graphics card? Then flash the BIOS so the memory speed is 500 MHz at default (would probably need 4 ns chips)? I have necessary equipment and enough experience with soldering to make it happen but I'm not sure if those chips are compatible at all.
Of course I could just buy another card but there is no guarantee that the next will be in full speed. So I would rather upgrade the RAM and be done with it.
