Thread: How to Overclock an Nvidia GeForce Graphics

If you chose the real-world test Remember That you'll want to test That's not limited by the speed of your CPU, that's Consistent from one run to the next and that's repeatable. Therefor you need a game that's graphically Demanding, and to find a section of That Game That Does not Differ from one play-through to the next. This Can Be tricky, so to test synthetic Might Be Better.

Synthetic tests Have the Benefit of Being absolutely Consistent from one run to the next, and They require very little setup time. A dog real-world test required hours of double-checking numbers, Finding and Eliminating inconsistencies and general frustration. However, synthetic tests Are just that, and while a 3DMark score of 14.000 12.000 Rather Than Might sound great, It Does not tell you whether your PC now CAN play Crysis and Very High detail.



Make your own decision on Which method to use, based on What You Want to Achieve. For example, if you're Trying to get to play Bad Company 2 passes over, It's Probably best to try to Develop your own real-world benchmark for this game. Good examples of synthetic tests Are 3DMark Vantage and Unigine Heaven , while Many built-in games benchmarks Have to Give a semi real world test.

Once You Have your baseline performance, you'll Need an application to overclock your GPU. Most Nvidia partners Have Their Own Custom Applications, pero Applications work with most cards, so as You Could Easily use Zotac's Firestorm, MSI's Afterburner or Another favorite. Unfortunately It Seems That Gigabyte does not have a version of OC Guru with Nvidia cards to use as it does with ATI ITS alternatives. GPU-Z is an excellent way to determine whether your application has Actually overclocked overclocking your card,

Overclocking Your application will present three crucial sliders - Core, Shader and Memory - plus manual fan control. Some Applications Have more options, But These Are the important ones for overclocking. The Shaders (Usually Called stream processors) Usually run at Twice the speed of the Core. For example, we've Used MSI's Afterburner to overclock Our Gigabyte GTX 460 1GB OC and we Had to drag the slider Core to 855MHz and the shader slider to 1.710 MHz

his Was the limit of the card by steadily Increasing the GPU's frequency in Increments of 50MHz and 10MHz Then from the 1.430 MHz 715MHz core and stream processor clocks That it ships with. Each Applied After we overclock, we ran A Few Our benchmark test times to see whether the card STI Would overheat at speed and whether the new overclock added extra performance and Stock. By reading Our Efforts In Our overclocking reviews, You Should Be Able to take a short-cut and start overclocking near to the limit of your card, or the final overclock That You Wish to Achieve.

We next INCREASED the speed of the memory card, again by sliding the bar upward in 50MHz and 10MHz Then Increments. We Settled on a final speed of 2.100 MHz Actually this is my "report from Afterburner, as it's forgotten That the GTX 460 uses GDDR5 s, which is quad-pumped, Rather Than GDDR4 s, which is dual-pumped. Effective today the overclocked memory speed of Our 4.2GHz WAS.
