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.

Table 7-12Solving 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 DIMM1 socket.

Ensure that a memory module is installed in the 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. ECC and non-ECC memory modules cannot be mixed.
