I then bumped it up a little more to 303/303. Again, I ran 3DMark2001 SE and it ran fine with a little bit of improvement, of course. My question is, since this is the first I OC'ed a card, how do I know when artifacts are present? Are they easily visible? How far should I go with OC'ed my card?
Thanks.
Artifacts are visible. On the memory, you will see flecks of white "snow" in 3d operation, and if it's too high even 2d will get really screwed up (often when you're testing how high a card will o/c, you will bump the memory too high and get lines everywhere in windows.. not a pleasant site).
On the core, you will get triangular/polygonal popups and weird screw ups in rendering. Basically you will notice something is screwed up with the 3d image.
I usually just set the card higher (ie up the core by 40 MHz or something) and then run 3dmark 2k1. If you get artifacts, immediately quit and drop the o/c a bit. Rinse, repeat.
You won't screw up your card this way as long as you're careful. Many people even run entire 3dmark benchmarks with lots of artifacts and popups at o/c's that are obviously too high to sustain because they get a higher score, and it's all a prestige thing to them (having the highest score). I usually just quit after seeing a few artifacts because there is no point in running anything 3d in this way in the first place.
