Solving Memory Problems

If you encounter memory problems, some common causes and solutions are listed in the following
table.

CAUTION:

Power may still be supplied to the DIMMs when the computer is turned off (depending

on the Management Engine (ME) settings). To avoid damage to the DIMMs or the system board, you
must unplug the computer power cord before attempting to reseat, install, or remove a DIMM module.

For those systems that support ECC memory, HP does not support mixing ECC and non-ECC
memory. Otherwise, the computer will not boot the operating system.

NOTE:

The memory count will be affected by configurations with the Management Engine (ME)

enabled. The ME uses 8MB of system memory in single channel mode or 16MB of memory in dual-
channel mode to download, decompress, and execute the ME firmware for Out-of-Band (OOB), third-
party data storage, and other management functions.

Solving Memory Problems

Cause

Solution

A memory module is not installed in the XMM1 (or DIMM1)
socket.

Ensure that a memory module is installed in the black XMM1
(or DIMM1) socket on the system board. This socket must be
populated with a memory module.

Memory module is not the correct type or speed grade for
the system or the new memory module is not seated
properly.

Replace module with the correct industry-standard device for
the computer. On some models, ECC and non-ECC memory
modules cannot be mixed.

Cause

Solution

Memory configuration may not be set up correctly.

Use the Device Manager to check memory configuration.
