Memory congurations

and optimization

Below is an overview of the memory congurations for the HP Z1 G2

Workstation and recommendations to optimize performance.

Supported memory modules

The types of memory supported on a Z1 G2 are:

• 4 GB PC3-14900U 1866MHz DDR3 Unbuered non-ECC DIMMs

• 2 GB, 4 GB and 8 GB PC3-14900E 1866MHz DDR3 Unbuered ECC DIMMs

• Single and dual rank 2 Gb and 4 Gb based DIMMs

See the Memory Technology White Paper for additional technical information.

Processor and memory support

* If ECC memory is added to the system, the ECC function is disabled and the DIMMs will appear to the system as non-ECC memory.

Platform capabilities

Maximum capacity: 32 GB

• Z1 G2 has a total of 4 memory sockets

• 2 channels with 2 sockets per channel

Speed

• 1866 MHz and 1600 MHz DIMMs are supported

• Memory will operate at the speed of the slowest rated installed processor or DIMM

Memory features

ECC is supported on Unbuered ECC DIMMs.

• Single-bit errors are automatically corrected

• Multi-bit errors are detected and will cause the system to immediately reboot and halt with an F1 prompt error message

Although HP does support non-ECC memory on this platform as a lower cost option, it should be noted that non-ECC

memory does not detect or correct single-bit or multi-bit errors which can cause instability or corruption of data in the

platform. See Memory Technology White Paper for more information.
