Remove it and try the card without it, if everything else is OK it should work. You can replace it with a 4.7uF-10uF 6.3V 1206 cap.

I haven't released the files yet, during bring-up I made some changes to the board, but didn't change the project files at the time. I need to find the board first, check what I did and then update the files. Even if I upload the files now, it's kinda useless, as some of the ICs aren't in stock for …

Only digital signals there, scanlines are visible probably due to some sync issues, in the SLI connector there is a SYNC signal, and only 1 RAMDAC is outputting video, but both RAMDACs are feeding clocks to the FBI (and TMUs from there), so maybe the issue is that there are two freerunning clock …

3.3V and VIO can be connected together for AGP 1.0 only, after that VIO is lower, 1.5V or 0.8V for AGP 2.0 and 3.0. No clue how much the 5V and 12V rails are used on old AGP cards. I can highlight, but a bit later today.

I have an AGP footprint in Eagle, would that help?

Wow, the old logo turned out great! Nice job! The bridge actually passes dogital signals, when SLI is active only 1 of the 2 RAMDACS is used (the one that detects the 75R VGA load). The signals passed through the bridge are digital signals from the FBI that go to the RAMDAC and some SLI sync …

There's no schematic available for it as far as I know, but there also isn't much on the board. What's wrong with it?

I think the 3dfx Donut demo lets you do that. Check the FBI pins as well.

Or get 2 blank PCI brackets and get creative with some tools. https://eu.mouser.com/c/electromechanical/har … uter%20Brackets

Poke FBI/TMU pins gently, most likely at least one pin is loose. 99% the RAM and TMUs are fine.

Damn, that's a nice to have card. The RAM might be SGRAM instead of the usual SDRAM (didn't check the partnumber, but usually SGRAM ICs are packaged like that). Edit: the boot screen also says SGRAM.

You can buy blank brackets and make what you need, if you have a drill, a small saw blade and some files. The end result can look extremely good.

It doesn't look that bad. Do you have a multimeter?
