Memory

This section presents dual inline memory module (DIMM) configuration information and removal/
installation procedures.

DIMM installation guidelines

Install only HP-approved ECC unbuffered DDR3 DIMMs. See
which DIMMs are compatible with the workstation.
CAUTION:
Because third-party DIMMs might not be electrically or thermally compatible, they are not supported by
HP.

Supported DIMM configurations

This workstation supports these DIMM configurations:
●
●

NOTE:
For maximum performance, install the same number of DIMMs per CPU. Install them in pairs of the
same size if your workstation has two CPUs.
* The 1110W power supply is required for a 96 GB or greater configuration.
** NUMA mode provides contiguous address space for each CPU such that a CPU can access its own
local memory faster than it can access memory local to another processor, or to memory shared between
processors.
