I put my ex athlon-xp 2800 heatsink with a 6000 round fan (noisy) and temps went down from 47°/64° to 39°/47° (idle/full load). Bios flashed with Sparkleultra from Seaman.
Nice job, but no much gain in OC 535/695 artifact free.
I think my VGA cannot go higher.
Someone have some ideas about how to go higher?

X seaman:
If you use the same bios, have you measured the real voltage of your card without Vmod? Does this bios really change the voltages or only it gives more relaxed memory timings?
It is strange that my GPU cannot go over 535 while the memory reach 700 (samsung 4.0) and now the temps are really low, so it is not a problem of overheating.
