The previous-generation games do not actually require a lot of system memory. By adding another gigabyte of RAM into the system we do not really boost the gaming performance. However when there are four 512MB memory modules installed, the performance drops down because of the forced 2T Command Rate setting. The performance drop in this case is about 1-2%.
The results obtained in the new F.E.A.R. game suggest that the latest games feel quite comfortable with 1GB of RAM in the system.
However, the results obtained in Quake 4 do not prove this statement. Additional RAM provides a significant fps rate increase. In the best case (when you have 1GB modules installed) the performance gain may reach up to 10%. This is the biggest performance improvement so far in our today’s test session.
