More of a question for the Offline section...My question is, who would use more than 4GB besides someone running a huge server?
A process can only use 4-gig. But I think the OS can swap processes into the 5-gig and use it all. The OS will keep track of which memory segments are being used for which process. I don't know is a 4 gig OS can use the swap space over 5 gig. The extra gig could be used for I/O buffers.so you guys basically mean that 4gb is slighty better than 3gb but 5gb is equivalent to 4gb (on a standard 32 bit machine)
