HP Z400 Workstation - Memory

This section presents memory module (DIMM) configuration information and removal/installation

procedures.

DIMM installation guidelines

Install only HP-approved unbuffered DDR3 DIMMs. See /go/quickspecs to find

which DIMMs are compatible with the workstation

HP ships only 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.

DIMM installation order

Review the following figures to determine the correct installation order for DIMMs.

Supported DIMM configurations

The workstation supports these DIMM arrangements, depending on which Z400 product you order:

Up to six DIMM slots

(the Z400 v1 has 4 slots; the v2 has 6)

Memory range from 1 GB to 16GB for the 4-DIMM product

Memory range from 1 GB to 24GB for the 6-DIMM product

(the Z400 v2)

No support for mirroring

No support for DIMM sparing

BIOS errors and warnings

The BIOS generates warnings/errors on invalid memory configurations:

If the BIOS can find a valid memory configuration by disabling plugged-in memory, it does so and

reports a warning during POST. the workstation can still be started. The warning will indicate the

location of the failed DIMM on the system board or memory riser.

If there is no way for the BIOS to obtain a valid memory configuration by disabling plugged-in

memory, the BIOS halts with a diagnostics 2006 code for memory error (five beeps and blinks).

Removing a DIMM

To remove a DIMM:

down the workstation (see Predisassembly procedures).

nect power from the workstation (see Predisassembly procedures).

To prevent electrical damage to the DIMMs during removal or installation, power off the

workstation and unplug the power cord from the AC power outlet. Otherwise, the workstation

may not recognize the memory changes.

the side access panel (see Removing the side access panel).

your system has an airflow guide, remove it (see Removing the airflow guide).

gently outward on the DIMM socket levers

as shown in the following figure.

/hpsc/doc/public/display?=3718668&docId=emr_na-c01747797-3&docLocale=en_US[4/26/2016 5:18:14 AM]

the DIMM straight up and out of the socket, then store the DIMM in an antistatic bag.

Installing a DIMM

To install the DIMM:

down the workstation (see Predisassembly procedures).

nect power from the workstation (see Predisassembly procedures).

To prevent electrical damage to the DIMMs during removal or installation, power off the

workstation and unplug the power cord from the AC power outlet. Otherwise, the workstation

may not recognize the memory changes.

the side access panel (see Removing the side access panel).

your system has an airflow guide, remove it (see Removing the airflow guide).

gently outward on the DIMM socket levers as shown in the following figure.

4:

the DIMM connector key with the DIMM socket key, and then seat the DIMM firmly in the

socket as shown in the following figure.

DIMMs and their sockets are keyed for proper installation. To prevent socket or DIMM damage,

align these guides properly when installing DIMMs.

the socket levers .

a 6-DIMM workstation configuration, replace the airflow guide (see Installing the airflow guide).

e all components that you removed in preparation for component installation.
