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	Single processor	Dual processor
per 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.
