Corsair Vengeance 8GB Dual Channel DDR3 Memory Kit (CMZ8GX3M2A1600C9)

Feb 12th, 2011 | By Simon


Detailed below are the specifications of the system used during testing:

  • Memory and Frequency

  • Corsair Vengeance 2x4GB DDR3-1600 9-9-9-24 – CPU @ 2.891 Ghz
  • Corsair Vengeance 2x4GB DDR3-1680 9-9-9-24 – CPU @ 2.865 Ghz
  • Corsair Vengeance 2x4GB DDR3-1880 9-10-9-27 – CPU @ 2.813 Ghz

You will noticed that the highest memory speed resulted in the lowest CPU speed. I tried to keep the CPU speed as close as possible to minimize the amount of variables that can affect the benchmark results. You’ll end up seeing some of the DDR3-1600 results beating the DDR3-1680 and DDR3-1880 as a result of this.

All benchmarks and tests were executed five times and an average was taken to derive the most accurate results.


3D Mark Vantage is a perfect example where CPU speed is far more important than memory speed. A 100 Mhz drop results in an overall score that’s a few hundred points less!


In PC Mark Vantage we can see what applications are more dependent on memory performance. This just shows that if I left the CPU multiplier alone the overall system performance would really take off!

Hyper Pi is more memory dependent than both PC Mark and 3D Mark and we can see a slight gap developing with increasing memory frequency and the results are further amplified in Everest when we look at individual Read, Write and Copy results for the memory.



The change didn’t negate the effects of increasing the frequency. Overall, we see a measurable gain in performance by overclocking even when reducing CPU speeds.
