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 16 MB 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.

Table 2-13Solving Memory Problems

System will not boot or does not function properly after installing additional memory modules.

Cause	Solution

A memory module is not installed in the XMM1 socket.

Ensure that a memory module is installed in the black XMM1 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.

Out of memory error.

Cause	Solution

Memory configuration may not be set up correctly.	Use the Device Manager to check memory configuration.

You have run out of memory to run the application.	Check the application documentation to determine the memory
	requirements.

Memory count during POST is wrong.

Cause	Solution

The memory modules may not be installed correctly.	Check that the memory modules have been installed correctly
	and that proper modules are used.

Integrated graphics may use system memory.	No action required.
