replacing gpu on voodoo 5500?

[flaming gerbil]

i have a voodoo 5500 and was wondering if anyone knew if i could replace one of the gpu's with a gpu from the v3 3000? are they the same chip? i was thinking since i can only overclock the v5 to 187mhz and i could get my v3 to 218mhz that perhaps one of the chips on the v5 was holding me back. if it is possible how would i go about doing it? is it as simple as pulling the chips of the v3 and replacing the v5, guess it could be the sli instructions also. thanks.

Goodluck i doubt it would work

Yeah, I dont think that would work, as the Voodoo3 GPUs arent made from the VSA-100 design, like the 4500 and the 5500.

Yeah, the V5 has VSA-100 chips and V3 was sometin else.

And the chips arent likely pin compatible, meaning that the traces on the board would go all wrong, be useless or get left unconnected. And the chips are PGA, meaning that they dont have such "legs" as yer CPU, but just little contact surfaces underneath, which are impossible to solder. They are attached at the factory with special assembly machines.

You know what I think, try using a heat gun from Menards or Home Depot and direct the hot air under the GPU with it, when it's hot enough the solder will melt and you can pull the GPU off the board, I don't think the heat gun will be hot enough to harm the GPU. I would think getting it soldered back would be the same method. If you do try it let me know how it works.

That would likely get all the other parts fall off too, so I dont recomend. Those little resistors etc. are set by a machine at the factory with a fraction of a millimeter accuracy, so trying to finger them back to their places would be very ... nerve wrekin.

Besides, this conversation is rather pointless, as removing the chip wouldnt help anything (different chips, V3 doesnt even do 32bit rendering nor support multiple chips). And attempting anything such (with heat blower etc.) WILL result in a wasted board.

The arcitecture of those two cards are totally different. Even if by some miracle you could get the chip to fit and get everything connected. You'd have to create your own bios to make everything work together with the new chip. You would'nt get FSAA either anymore. As thats a product of the VSA 100 chip.

But all in all I'd find it pretty well impossible without revamping the whole card.

thanks, ain't gonna try it.
