if 3dmark would just let me print screen you would see it a whole bunch better ...

to get these effects i raised my mem clock from (317.5)635 to (330)660 BTW

Ok, thanks for the pics. I kind of figured thats what they were as I could see something just like that in the sky in 3dmark01. So that just comes from too much o/c and not enough cooling? Also is it usually too much o/c on the core or RAM or can it be both?

It tends to be that a too high mem oc produces artifacts, while a too high core oc produces crashes.

Yes, it often results from bad cooling, but cooling isn't the only limit to overclocking; the chips themselves are too.

i found its usually the ram going edgy from too much oc'ing not enough cooling ; when u oc the core too much it usually just freezes

[HeXenViRii]

ahh , beat me to it :D

[wannaoc]

Very nice, I have sinks coming in for my RAM this week so hopefully I'll get a little more out of it. Now I'm off to see if I can pull a little more out of my core. :)

good luck !
