So I recently received two Radeon 9200 cards.

1) Red / PowerColor: This one works (after some tests atleast) but two capacitors have been replaced by previous owner, they Chonxing / Chanxing brand and I was wondering what the original values were, 1000uf most likely but they probably were rated lower than 16v? Reason I ask is that I already have 1000uf solid caps which are however rated 6.3v.

2) Green / Sapphire This second one does seem to have clear VRAM issue. Picture is corrupted mess of varying degrees, however aftrr messing Radeon bios editor I created bios which had only 64MB enabled (half of actual) and I was able to run 3D Mark 2001 without a single issue / artifact, however on next boot it was back to garbled mess, sometimes picture is messed in bios already, sometimes not etc. so it changes. This probably is simply VRAM issue, not capacitor?

Those two caps are rated 1000µF low ESR on the VDDC (gpu core voltage) which is 1.62V nominal. You're completely fine using 6.3V parts here, nothing to worry.

The error pattern you see is very "memory-esque", so you could try a graphics card memory test. Unfortunately there is no R2MEMID that I could find, so you'd have to check with generic tools like here: Re: Radeon R200 and R100 memory test tool

You changed the memory to 64MB, however it'll most likely still use the full 128Bit memory bus (as stated by GPU-Z as well) - You could try flashing a BIOS from a 64MB/64Bit card for testing, that'd give you an idea which memory channel is affected.

You can use R6XMEMID to check the faulty memory chip: Re: VGA Repair report collection
