Are they artifacts or errors?...

[Tyranos]

Ello.. system in question in sig (only changes are 768mb pc2100 and 136x11 fsb multi 1.5ghz) When I'm running 3d mark there will be 3 tests in which the geometry will flicker from normal to black. Dragothic (not as bad), Nature (bad), and the donut thing bump mapping. Though the last doesn't have any black, it looks more like little lighting flashes all over the surface. I was wondering why these things are showing up? Do you think they're artifacts? If so, why would they show up on a non overclocked card? :\

I've also ran artifact tester, and according to it, I don't have any artifacts. hmm

Yeah I still get the black flickers even at 299.3 core and 570mem
