PCMark05 is an application-based benchmark and a premium tool for measuring overall PC performance. It uses portions of real applications instead of including very large applications or using specifically created code. This allows PCMark05 to be a smaller installation as well as to report very accurate results. As far as possible, PCMark05 uses public domain applications whose source code can be freely examined by any user.
PCMark05 includes 4 categorized suites for benchmarking your computer. These include CPU, Graphics, Memory and a Hard Disk Drive benchmark. In our case, we selected to run only the Memory test suite.
In this test, although all results were similar, the Corsair TwinX2048-4000PT memory was the fastest of the three.

You should always remember that most PC memory benchmark software can indicate the operating performance according to the speed of the RAM memory. However, in real life, having 2GB of RAM is surely a big boost to any system's performance, over 1GB. But in numbers, the timings used for 1GB are 2-2-2-5, while timings for 2GB are 3-4-4-10 or 3-4-4-8. Also, keep in mind that the Corsair memory we are testing here operates at 500MHz, like the Apacer memory did. In some tests, the Corsair memory running at 400MHz with 2-2-2-5 timings might report better results than the same memory running at 500MHz with 3-4-4-8 timings.
