Re: Voodoo card chip legs repair

I have done few of these and with my tools by far the easies method is to pull the chip off from the board, straighten/clean legs while the chip is off and then put it back.

Hello again! This time around i have another V5 5500 on the healing bench. The card belongs to a member of this forum. Basic info: - Non modified Rev 2500 V5 5500 AGP - Suddenly stopped working, heavy artifacting during POST/boot and crashes in windows - Judging from dust and fan motor wear the card …

And we have results. Most ceramic caps on graphics cards are just for power rail decoupling and their value or presence is not too critical. But this area of the card is different. Right at the other side of the card we can see PWM regulator ic LTC1929. Regulators may have capacitors other than just …

I can desolder and measure this capacitor for you. I have rev 2100 and 2500 cards on the healing bench right now.

Just for curiosity, are these GPU chips you bought original surplus ones, or does some Chinese company manufacture new chips for hobbyists? Original surplus for sure. More than likely after the shutdown of 3DFX manufacturing plants all unused proprietary ICs were sent to be scrapped as e-waste and …

^ My thoughts exactly. Large memory cards i have seen or heard of seem to be pretty difficult things to get running stable. The mod can be done with smd components, thinner green wire and no hot glue but it is still visible.

can you fix artifacts at bios on ATI Radeon 9xxx cards ? I might, but im not sure if its worth of doing Do you know how to upgrade the card to 128MB? Yes but so far only PCI version. AGP should be doable but the layout is little bit different so it would require some reverse engineering or asking …

To me this sounds like a missing component, break in solder joint(s) or in the pcb traces. There may be a signal or signals that need to be pulled to ground for example in order to card to function correctly. Now if that line is broken, or if the possible pull down resistor is broken or missing that …

BGA reflow is somewhat simple operation but this machine does more than just heat up the solder. It has prismatic camera aided pick and place function which of course is not needed for ICs this old and large :) It is extremely nice to have when you work on something that has 0,3mm balls and no silk …

VSA-100 3dfx cards have been altered to 1.5V AGP as well but they require more rework on the pcb than just cutting a notch.
