After reading about the 3/GB switch option in Windows I am still unsure of when to set it. It describes the allocation of the 4/GB of virtual address space between apps and the kernal. Does the 3/Gb switch have anything to do with the amount of physical RAM in the PC? I just increased the amount of RAM in a PC to 2.5/GB so that I can run Adobe CS3, this is when I began reading about the switch. I always thought it was related to physical RAM not virtual memory.
Any help would be appreciated.
