Memory Performance

We measured memory performance using the memory performance module of PCMark05 Professional program. The results are given in a specific unit of the program. The methodology we used you can check on the “How We Tested” section.

We also ran the system benchmark provided by PCMark05. However, the system performance remained on the same level with all memory modules we installed.

The results you can see on the chart and table below.

Patriot PDC21G8500ELK DDR2-1066 PC2-8500

Memory Module Score Difference
Corsair CM2X512-8500C5 (DDR2-1066) 5,898 0.10%
Patriot PDC21G8500ELK (DDR2-1066) 5,892  
DDR2-800 Simulation (5-5-5-16) 5,689 3.57%
Corsair CM2X1024-6400C3 (DDR2-800) 5,684 3.66%
Corsair CM2X512A-5400UL (DDR2-667) 5,633 4.60%
DDR2-667 Simulation (5-5-5-13) 5,582 5.55%
DDR2-533 Simulation (4-4-4-11) 5,473 7.66%
Corsair CM2X512-4200 (DDR2-533) 5,464 7.83%

Keep in mind that a higher performance of the memory subsystem does not necessarily translate into a higher system performance.
