Maximum Memory Allowed; Hpikl/Factory Preinstalled Systems - HP xw3400 User Manual

Summary
Various HP Linux Workstations can support large memory configurations (greater than or equal to
4GB). To use large memory configurations, an SMP, hugemem, or bigmem kernel must be installed
and configured. Even though a system may have more than 4GB of memory, 3GB is the maximum
amount of memory that can be used by a single process for HP Workstations running the uni-
processor kernel.

Maximum Memory Allowed

The maximum amount of memory that can be physically supported on HP xw Workstations:
1 CPU*
xw4100 4GB
xw4200 4GB
xw4300 8GB
xw4400 8GB
xw6000 8GB
xw6200 8GB
xw6400 16GB
xw8000 12GB
xw8200 16GB
xw8400 32GB
xw9300 16GB
xw9400 16GB
*If there is only one CPU but Hyper-Threading Technology is enabled, the maximum amount of
memory supported equals the value in the 2 CPU column. Although you can physically install 4GB
memory, only 3 to 3.5GB will show up as addressable with a uni-processor kernel.
The maximum amount of memory for each workstation is limited by the number of memory slots on the
system board and the maximum size of the supported memory sticks. The maximum amount of
memory recommended for each Linux version varies depending on the kernel that it includes. See the
current Linux Hardware Support Matrix (
maximum memory currently verified for your configuration.

HPIKL/Factory Preinstalled Systems

If your Linux system has 4GB or more of memory and the Red® Hat Linux OS was either preinstalled
at the factory or installed using the HP Installer Kit for Linux, the correct kernel for supporting the large
amount of memory should be automatically installed and configured.
