Patriot Viper DDR3 2000MHz 2x2GB Review

» Discuss this article (1)


The best 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, whether good or bad. In order to eliminate the variables, the only settings that will be manipulated are the memory timings and voltages when overclocking. The comparison modules will be run at the manufacturer specified timings and voltages at 1333MHz, the common DDR3 speed. The Patriot Viper 2x2GB kit will be run at stock timings and voltages at 1333MHz, 1600MHz and finally overclocked to the highest frequencies reachable. The G.Skill kit just could not make the 1600MHz mark, so it was excluded from that level of testing.

Testing Setup:

Comparison Modules:


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 (%).



Overclocked settings:

  • Processor: Intel Q9450 @ 425x7 with 1.368 volts
  • Memory: Patriot Viper DDR3 2000 @ 1700MHz @ 9-9-9-24 and 2.0 volts

When it came down to overclocking the Patriot Viper DDR3 kit, I was very disappointed as I was unable to hit the rated 2000MHz on my X38 chipset.  However, I was able to reach 1700MHz with the rated voltages as well as the rated timings. I was able to increase the FSB by about 10-15MHz every attempt and run MemTest to make sure that the overclock was stable.

As an enthusiast community, we tend to push our hardware to the max all the time. At OverclockersClub, we do not condone running your hardware outside of the parameters set by the manufacturer and will not be responsible for any damage to your hardware while trying to duplicate the results of our testing. With that out of the way, let the testing begin.


The benchmarks that will be used in this review include the following programs:


  • CPU-Z Version 1.45
  • Windows Task Manager
  • PCMark Vantage
  • SiSoft Sandra XII
  • Company of Heroes
