I just used rivatuner to Overclock my 4870 and after doing so and running Empire: Total War I'm getting luminous lights and dots with lines that look like graphical glitches, any idea what it is?

EDIT: I can post a screenshot if completely necessary, although it would be a hassle as this isn't the same computer.

during or after the overclock?

Im assuming during the overclock.. i think theyre called artifacts or something, just reduce the amount you overclocked by until you get a good amount

Well, I can only assume it worked, first time trying this thing(manually). I kept the sliders within the highlighted areas and it was after I overclocked(if I done it correctly), playing a game. My GPU Clock is at 840 and my Memory Clock is at 1050. When I originally used CCC overdrive it set it to 750/1095 however, I changed it to that and still had the same problem. My temps actually didn't change that much from my idle temps because I had the problem before I actually got into the action.

Yup it's artifacting. However you mentioned when you clock to your default 750/1095 you still had the problem? If you're dead set sure that you artifact at default, with a clean install of the driver, it might be time to RMA... Do you get the problem with other games though?

it should be fine if you haven't touched the voltage.

You are artifacting it sounds like. I have my 4870 watercooled and only run GPU Clock @ 825 and memory clock at 1025. I'd say turn them down a notch and you will be fine. As long as you aren't adjusting the voltage, you won't damage it.

Yeah I just turned them down a little, seems to be fine so far besides the temp increase, but I can just turn the jet powered fan up.. at least I think its jet powered, it sure sounds like it.

Thanks for the answers.

That's the downside of a "reference" cooler. Next time when buying a videocard look for one with an aftermarket cooler
