I've received this Asus GF DDR that at first try didn't show an image at all but after a wash and cleaning, seems to get to windows without an issue, albeit only in safe mode or without the correct driver loaded. HWiNFO32 also recognises the card, in the screenshot pay attention to 16mb AND 64-bit. If I try to load the correct driver, windows won't load with said driver.

Other symptoms are the card sometimes showing 16, sometimes 32 megs of memory. So it's not one of those ULTRA RARE 16 megabyte monsters. Image sometimes gets garbled straight away at boot but other than that there's nothing to complain about in terms out output quality, compared to my other Geforce DDRs.

There are no obvious scratches, dents or bent/loose legs on the PCB/components, and after cleaning, the board seems to be in overall good condition. Caps haven't bulged, 3x Rubycon YXG 6,3V 1000uF and 1x no-name I assume 4V 510uF but that of course won't mean anything as the card runs hot. The fan for sure is dead so there's a 50mm replacement currently in place.

This sounds like a memory issue but is the memory itself bad if it occasionally gets fully recognised? Power delivery or bad joint somewhere (where?) maybe?
