Problem With Desktop PC - Page 4

I prefer Afterburner too. Rivatuner and Afterburner both use the same engine so they are very similar underneath. Afterburner offers a few more features and the interface is also alot better. I agree that overclocking your CPU from bios would be best but you can start out with Overdrive if you feel more comfortable doing that.

I'm assuming that your video card is some kind of green edition? Reference clocks for GTS 250 are 738/1836/1100. You should start overclocking by raising your clocks ~15MHz one at a time and testing for artifacts with FurMark or Kombustor (samething). Keep an eye on your temperatures and make sure that your GPU temp does exceed 100C. Make note of temperatures if they rise any higher than 90C. You shouldn't need to run it any longer than 5-10 minutes to test for artifacts. Once you encounter artifacts you should back off of your clocks ~10MHz, following in 5MHz intervals if necessary, and run FurMark one final time to confirm you no longer see artifacts. Once you've found the maximum clock for the core move onto shaders and then memory. You can use OCCT to check for vram errors after you've run FurMark artifact-free.

If you had a reference card I could give you an idea of what kind of clocks to expect. Given that you have a green card, I can't really tell you. I would hope you could atleast match my 8800GT's stock memory clock (900MHz) and hit reference core and shader clocks for the GTS 250. That might be a bit optimistic though. You should be able to do atleast 700/1750/900 but that's just a guess.

You have 230-240V which is the same in Ozzie, any major brand of PSU above 550W should do it.

Thanks for the answer... i was using EVGA Precision and overclocked core, shader and memory clock for +15% from the default values. And it was pretty stable... pc freezes only once... playing CoD MW at max. settings. The temp goes from 50-60C in gameplay and 30-35 in "idle" (browsing and few apps running). Here is a pic from the GPU default clocks. How high should i go? And please recommend me a software for overclocking the CPU except AMD OverDrive?
