Here is the card itself, I can't actually see any ram chips on it...?

EDIT: Cross checking with chatGPT:
If you're failing a "buffer memory test", it means the internal SRAM inside the KTC8801 is damaged — not an external chip.

Sounds like the card is toast.

I got around to installing the card in another system (First machine was a P200, second a Am5x86). Qstart passes all tests! No sign of the buffer memory failure.

Next step install the drivers and test it out...

Sounds like a resource conflict rather than a hardware failure. This is another example of why a story-telling AI is not something to trust with technical details or conclusions. It told you what was most likely based on other text online, not on whatever your card was actually doing.

If you hit driver issues, remember that this is a pretty generic RTL8019 card, so if you can't find specific Kingston drivers, just use the Realtek ones. They might actually still have them on their site...
