3D Mark 05/06
Here we see how FutureMark's 3DMark 05/06/Vantage are affected by the increase of the installed memory. The previous versions of the 3DMark 05/06 benchmarks seems to be designed to work with 1GB or 2GB of system memory in order that they can be run on the widest possible range of systems. As a result, increasing the memory (2x2GB) did not show any performance improvements here, in fact we got even lower scores..
3D Mark Vantage
The 3D Mark Vantage scores were slightly better in the 4GB setup, mostly at the resolutions of 1280x1024 and 1920x1200 resolutions.
Company Of Heroes, Half Life 2
This is another popular game title for many users. Again, adding more memory did not provide any significant performance gain neither in low nor in high resolutions.
Finally the e Half Life2-Episode 2 game title also did not run any better after installing the 4GB memory modules.
