what is the maximum amount of ram memory that windows xp recognizes
32 bit Windows XP has two well-known memory limits. Each process is limited to 2GB of memory (or 3GB if you change a setting). The maximum memory that Windows XP will use in total is 3.25GB. There is no fundamental 4GB limit for memory in 32 bit operating systems - Windows Server 2003 can use more than 4GB. The key limit that defines a 32-bit system is per-process (the virtual address space for one particular application).
