So, got this Quadro4 750 XGL card, which obviously have some vram problem. The BIOS font characters are garbled, video artifacts in VGA mode, higher resolutions than 640x480 8bpp won't work at all. Ran "Video Memory Stress Test", and it reported tens of thousands of memory errors.
Thinking of trying to reflow the vram chips as a last resort. There are eight of those chips, and the problem really is broken solder joints, I'd be really surprised if more than one or two of them suffers from it. There's probably no need to reflow all of them at least, and since reflowing with the crude tools I've got at my disposal isn't completely risk free after all, I'd like to keep it to a minimum.
VMT produces logs with the faulty memory addresses. Is it possible somehow to pinpoint what specific physical chip(s) those addresses corresponds to, and in that case, how do I go about it?
