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
http://www.hp.com/go/quickspecs
to find
which DIMMs are compatible with the workstation.
CAUTION:
HP only ships DIMMs that are electrically and thermally compatible with this workstation.
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:
●
Twelve DIMM slots
●
Both Unbuffered ECC and Registered DIMMs
●
Memory configuration from 1 GB to 192GB*
●
Total DIMM count:
Independent channels
per processor
Single processor
Dual processor
Single
Two
Four
Dual
Four
Eight
Three
Six
Twelve
●
In dual processor configurations, the workstation can be configured for NUMA** or non-NUMA
modes
●
No support for mirroring
●
No support for DIMM sparing
NOTE:
Do not intermix unbuffered ECC with registered DIMMs.
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.
