Modify leadtek A280 VIVO - 128mb <64mb?

[gstanford]

I have a client who has a Geforce 4200 (leadtek A280 VIVO).

The card overheats and has corrupt graphics due to a faulty ram chip on the back of the card at the top (card has never been overclocked). I suspect the wrap around heatsink may not have been contacting the chip correctly.

Is it possible to desolder the rear ram chips and flash the card to be a 64 mb model?

I suggest that the surface-mount soldering skills for BGA RAMs is beyond the capability of most consumers. If you live in the SF bay area, Solectron does this kind of thing one-off, but buying a new video card would be less expensive.

Yes, the client has bought a new 6600GT. He was interested in the possibility of saving the GF4 (I already pointed out the cost would be more than the resale value of the card anyway).
