Pictures of the card's back would be appreciated.

Done!

If someone is able to fix it (but isn’t something I could do). Happy to give the card away.

Since they aren’t making more of them feels wrong for it to be trashed.

i would gladly take it to fix it... pm me for details

Dibs.

Repeating patterns are typically memory errors. With so few artifacts visible this would appear to be a single bit or single address line.

I’ve not had chance to look at the photos in detail, but I wouldn’t be surprised to see some physical damage.

You can test broken traces by squeezing individual memory chips with your fingers and then starting up computer, or running something rendering graphics on whole screen and squeezing ram chips one by one. Order of operations is important because just reconnecting broken trace wont show up on the picture without system refreshing memory with bad data.

That's exciting news that it might just be the memory chips!

Does anyone know if I need to order the exactly same SGRAM chips? I see https://www.ebay.com/itm/153351528490 but no idea if it will work.

KM4132G512Q-7 means 7 ns memory chips, to slow for a Voodoo3 3000, because 7 ns is specified for 143Mhz like the Voodoo3 2000 PCI card with SGRAM. The 3000 SGRAM version needs 6 ns (166 MHz specified) SGRAM memory chips. Your broken card has 6 ns chips. I would look for the faster 5,5 ns SGRAM chips (183MHz), then you have more leeway when overclocking and install a fan on the heatsink or use a case fan behind the card, because the Voodoo3 cards are getting very, very hot without any active cooling!

I had the same problem but it was vertical red lines. It was one of the memory modules that was dead. I found a compatible module on another video card that I don't remember the model. I easily replaced it using a simple hair dryer and a little solder flux.
