A few days ago, I bought the following machine. Intel Core i5-2500K COOLER MASTER Hyper 212 Plus SAPPHIRE Radeon HD 6950 2GB G.SKILL Ripjaws Series 4GB DDR3 1600 9-9-9-24 Crucial RealSSD C300 64GB SATA III ASRock P67 PRO3 COOLER MASTER HAF 912 XFX P1-650X-CAG9 650W ATX12V 2.2 Microsoft Windows 7 Home Premium 64-bit While I’ve been waiting for it to show up, I’ve come up with a plan for over-clocking it. I would appreciate it if you let me know how I can make my plan better. I am looking to increase the performance of games like Mass Effect 2 and Left 4 Dead 2. I am going to use these benchmarks to measure my improvement: Far cry 2 Stalker call of Pripyat Heaven In principle, my strategy for the CPU, CPU memory, GPU, and GPU memory is: 1) Ensure that the component I bought is stable at advertised speeds. 2) Assuming it is, identify a maximum voltage given my risk tolerance. 3) Set the voltage to the highest value I will tolerate. 4) Identify a maximum temperature given my risk tolerance. 5) Increase the clock 6) Test whether the component is stable and that I am below my temperature tolerance. 7) If unstable or above my temperature tolerance, then decrease clock and test again. My goal with the voltage and temperature tolerances is to hit a point where I am getting a good performance increase, but not seriously diminishing the longevity of the part. Please let me know if any of the values I provide below are too conservative or aggressive given this goal. I don’t want to run stress tests for too long, because I don’t want over-clocking the machine to take forever. However, if I run them for too short, I may miss stability issues. I am inclined towards an hour per test. Is this a reasonable place for striking this balance?
