So I am having the PC on my sig. The CPU is having a FSB of 533 MHz and 2 MB L2 Cache. It scores 4.8 on the Windows Experience Index(WEI).When I bought this notebook it had only 1GB DDR2 667 MHz RAM (2X512 MB) which I later upgraded to 2GB DDR2 667 MHz(2X1024 MB). Even though both the RAM modules were functioning in dual channel mode, my WEI for memory remained constant at 4.4 even after upgradation which I think is pretty much low. Do you think the RAM modules are running at 533 MHz because of the FSB of the CPU ? Now if I upgrade to say a T7200(667 MHz,4 MB L2 Cache),will it improve my situation and make the memory run at normal speed?
