Solving memory problems

If you encounter memory problems, some common causes and solutions are listed in the following table.
IMPORTANT:
the Management Engine (ME) settings). To avoid damage to the SODIMMs or the system board, you must
unplug the computer power cord before attempting to reseat, install, or remove a memory 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 8 MB 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.
System will not boot or does not function properly after installing additional memory modules.

Solution
Contact an authorized service provider.
Solution
Ensure that a memory module is installed in the SODIMM1 socket
on the system board. This socket must be populated with a
memory module.
Replace module with the correct industry-standard device for
the computer. On some models, ECC and non-ECC memory
modules cannot be mixed.
