Patriot Viper Fin Extreme Latency PC2 6400 Review

Testing:

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 800MHz. In order to reach higher memory speeds, the memory will be run unlinked to take the CPU speed out of the equation and allow the memory speed to be the only variable for my performance measurements.

Testing Setup:

 

 

CPU-Z: This application shows us the settings that we have chosen in the BIOS. Items shown in this application include CPU speed and bus settings, motherboard manufacturer, BIOS revisions, memory timings and SPD chip information.

 

Task Manager: We use this utility to show physical memory, kernel memory, page file usage and processor usage (%).

 

Overclocking:

Overclocked settings:

  • Processor: Intel Q6600 266-272 x 9
  • Memory: Patriot Viper Fin PC2 6400 617fsb (1234MHz) 5-4-4-10

So just how well did the PC2 6400 Viper Fin modules perform? Well at CAS 3 (3-4-3) the limit was reached fairly quickly. At 420 FSB the limit was reached. 2.4 and 2.5 volts would not let it past this mark. Moving the CAS latency to 4 (4-4-3) provided a whole new world of speed. The maximum speed for 4-4-3-was 520 FSB. At 4-4-4 540 FSB was achieved. Thinking there had to be some more left in the modules I moved the CAS latency to 5 (5-4-4). At CAS 5 I was able to reach a bit over 600 FSB, 617 FSB to be exact. Based on how you wish to run these modules there will be a speed that can be used at a 1:1 ratio. 217 FSB worth of overclocking headroom is pretty phenomenal. While it took an increase in the latencies to reach the final speed of 1234MHz, the other modules have the same issue. Overclcoking is a game of compromises, a tweak here, a bump in the voltage there, it all works out to get the final result.
