[QUOTE="cwa107, post: 684310, member: 24098"] A 32-bit operating system can address up to 3GB of RAM. If you have more RAM beyond that, you'll need a 64-bit operating system to address it, otherwise it will be inaccessible. A 64-bit operating system doesn't require a certain amount of memory, it's just a prerequisite to addressing anything above 3GB. [/QUOTE]
