I finally topped out the FX 5200 Ultrta at 380c /750m, actually thats a lie, the memory did 760MHz and was still going strong but for some reason I thought it would impinge on my core speed so knocked it down. I'll try it again this weekend.
3dmark2001 score was 13 800 which is higher than any 5600 or 5600U as well , not bad for a cheap card though it ended up with a LOD of 6.5
I tried my Peltier cooler on a copper cold block ( rather than the card ) to see how it went ..very well, except for the massive condensation
so I will have to rethink that .
