The way to verify that one set of memory modules is better than another is to run a series of benchmarks to put down some basic comparison data. When all things are equal and the only variable is the module being tested, the results are a great way to compare performance, good or bad. In order to eliminate the variables, the only settings that will be manipulated will be the memory timings and voltages when overclocking. The comparison modules will be run at the manufacturer specified timings and voltages at a speed of 1333MHz. In order to reach 1333MHz and 1600MHz, the processor used in the test setup will have a slight overclock from 266MHz to 333MHz and 400MHz. All of the comparison modules were run at 1333 MHz, with the Patriot run at both 1333MHz and 1600MHz to test the modules at each level.

The Patriot Viper Fin PC3 12800 was fairly easy to clock up to 962FSB (1924MHz). To get the most from this set of memory I will use the 1:2 divider to scale the memory as high as I can. This set of memory has the ability to run extremely tight latencies of 6-5-5-16 at 1333MHz. Starting at 1600MHz, I was able to scale up to 1840MHz with the stock 7-7-7 timings, using 1.9volts. Above that, even more voltage was required to maintain the the CAS latency of 7. At 1880MHz I needed to move the CAS latency to 8 to continue raising the clockspeeds. Once 1900MHz came around, more voltage was needed to maintain stability. By limiting the voltage, I ultimately limited the clockspeeds that could be achieved, but 1924MHz (962FSB) at 8-7-7-20 is nothing to shake a stick at. In fact, 38MHz more puts this memory into the 1000MHz club. Where is that 500FSB quad when you need it?
