Best RAM for your PC...
Always go for the fastest memory that your motherboard can support (and your budget can stretch too). But be aware that some of the new motherboards will always have bugs which may limit performance and compatability in the early stages of release - keep an eye out for BIOS upgrades and if affected, throttle back the speed to stabilise the system.
Bear in mind that 32 bit applications can only access a limited amount of RAM, so do not exceed 4GB and take a look at this page for more information:-
Memory Limits for Windows Releases
Windows 7 64 Bit Operating System is not so constrained and supports up to 192GB of RAM ... but, be aware that running a 32 bit application on a 64 bit system entails creation of an emulation mode which in turn is limited to 2GB of RAM!
More Information on Random Access Memory can be found here at Wikipedia
We always choose good quality RAM which is extensively tested before despatch.
