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.

The PCMark memory tests indicate that the Corsair XMS PC3200 memory is faster than the PC4000 memory. This mainly has to do with the timings and not with the running frequency. You can easily set the Apacer Real500 memory to operate at the same timings as the Corsair memory (2-2-2-5). We experimented with the timings at 2-2-2-5 and got similar results to those of the Corsair XMS memory. However, we chose to do ours tests without making any changes of this kind, since most users will operate the memory at its standard settings.
