Go up in small increments and each time test it out in a game or someother graphically demanding app to make sure you dont get any articfacts. You know you have gone to far if you get artifacts, so if you do then take it back down to the last speeds that worked.

Yea you should be able to get the core to 540, you want to download coolbits for this.

Its a reg file, open it and add it to your registry, restart, then right click desktop, properties, settings, advanced, then click on your card (6600) and find clock frequencies, this is where you can overclock it.

like the best i have gotten is 380 core, and 571 mem

I thought you meant the core was 500 oops. Yea idk if you can get the core to 540, 400 is still pretty good and that other post the person might have had a 6600gt.

he had the "le"

when you are ocing, do you ahve to have checked, apply these settings at startup? if not does it apply them right then

ive had the rivatuner i didnt see much to do with that, still limits you to speeds, trying riva again now

umm ya, did i say it was correct, nope. did it say it was right, yep.

i wanna get it has high as possible while being stable, it was stable at 400 core, so obvivously that program is wrong.... will a card just blow out of no where if there is no artifacts.
