HP EliteBook 8540P Specification

DDR3 PC3-10600 SDRAM (1333 MHz) *
Two or four SODIMM slots supporting dual-channel memory
SODIMM sizes supported: 2048 MB and 4096 MB
NOTE: Four memory slots only on models with quad-core processor.
Standard Memory 2048 MB (2048 MB x 1)
4096 MB (4096 MB x 1)
4096 MB (2048 MB x 2)
8192 MB (4096 MB x 2)
8192 MB (2048 MB x 4) **
12288 MB (4096 MB x 2 + 2048 MB x 2) **
16384 MB (4096 MB x 4) **
Optional Memory Upgrades Support for up to 16384 MB ** of memory with the installation of optional DDR3 SDRAM
memory kits. All memory slots are user-accessible. Please refer to the Hardware and
Software Guide for installation procedures. Maximized dual-channel performance requires
SODIMMs of the same size and speed in both memory channels.

* With some processors, memory bus runs at a maximum of 1066 MHz.
** Requires quad-core processor configuration with four memory slots.
NOTE: This chart does not represent all possible memory configurations. Due to the non-
industry standard nature of some third-party memory modules, we strongly recommend using
only HP- branded memory modules to ensure compatibility. If you mix memory speeds, the
system will perform at the lower memory speed. Full availability of 4 GB or more of memory
requires a Windows 64-bit operating system or Linux. With Windows 32-bit operating
systems, the amount of usable memory is dependent upon your configuration, so that above
3 GB all memory may not be available due to system resource requirements.
