Corsair XMS2 DHX DDR2 800MHz 2 x 2GB Review



Now I am excited about the testing phase. Being  intrigued by the design of the modules, I wanted to see how well they actually perform, since looks are not everything. I will be running a series of benchmarks on the Corsair XMS2 DHX memory that will stress and push the modules to the limits to see how well they stand up during tough use. I am also going to be comparing them against other memory sets at the same speeds and timings as the XMS2 DHX modules. To accomplish this, the other comparison sets of memory will be clocked at 800MHz and manually set to 4-4-4-12 timings at 2.1v. This will give an accurate side by side comparison between each set. All other hardware for the system will be set to their stock speeds, timings, and voltages to eliminate any variables from interfering with the scores.


Testing Setup:


Comparison Modules:



CPU-Z: This is a great program to use in order to view the settings that we've set in the BIOS including, CPU speed, 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:

  • Memory: Corsair XMS2 DDR2 800 @ 1000 with 5-5-5-15 and 2.1 volts

To start off the overclocking on the Corsair XMS2 DHX memory, I started pushing the frequency up by changing the memory dividers on the motherboard BIOS. I was able to get the memory to 1000MHz by loosening the memory timings to 5-5-5-15 and keeping the voltage at 2.1v. I did try to get the RAM to go to 1066MHz by raising the voltage to 2.2v, however it would not remain stable at 5-5-5-15. I was able to get them stable at 6-5-5-18, but the scores were lower than at 1000MHz (5-5-5-15) so that is what I stuck at. The overclocking tests will be run then at 1000MHz with timings of 5-5-5-15 at 2.1v which is a 20% overall overclock for these modules.



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


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