thanks for the reply, i play games with 1024 x 768 resolution but even if I lower the resolution the game is still slow, anyways if i try to trouble shoot it by replacing the memory instead of dr2 667 change it to ddr2 800? or just simply replace my cpu?
Upgrading from DDR-667/PC2-5300 to DDR2-800/PC2-6400 may not work unless your motherboard is designed to work with the faster RAM. I have found that some motherboards do work with faster than manufacturer's specified RAM. CL 4 is faster than CL 5. Some brands of RAM are better than others. I use MemTest to test the speed and for errors. It is best to run at least two passes.
