Intel i5-2300 2.8GHz Sandy Bridge CPU Review - Testing Methodology

The Test System:

CPU: Intel i5 2300

Motherboard: MSI P67A-GD55

RAM: 2x2GB Patriot Viper Xtreme 1600MHz DDR3


HDD: Seagate 1TB 7200.12 and Patriot Pyro 60GB SSD


Testing Methodology

We will be testing a number of settings, measuring an array of performance parameters, and then making comparisons, using the results to draw relationships between clocks, voltages, power draw, and resulting performance.  We will be modifying the voltages in the BIOS at a given clock, then running Prime 95 to test for stability, and once we get a stable configuration, we will push the voltage down until we become unstable, then run our  tests at the lowest stable voltage.  We will use our results to draw conclusions about the relative efficiency of the chip as it is stock, and other relationships that become apparent through our comparison testing.

Thanks, I really needed this. I moved to a Picopsu and bought a very high efficiency adapter but failed to see that 12V only operates up to 4.5A. Thus whenever I opened a video file, the computer would die. Underclocking solved the problem beautifully, and now I can run two HD videos side by side if I want!
