Memory
Latitude E5400 and E5500 support a maximum of 4GB of memory* when you use two 2GB
DIMMs. 32-bit operating systems, such as the 32-bit version of Microsoft® Windows® XP, can
only use a maximum of 4GB of address space. Moreover, certain components within the
computer require address space in the 4GB range. Any address space reserved for these
components cannot be used by computer memory; therefore, the amount of memory available
to a 32-bit operating system is less than 4GB.
Memory modules should be installed in pairs of matched memory size, speed, and technology
for optimal performance. However, even if the memory modules are not installed in matched
pairs, the computer will continue to operate.
