Solving Memory Problems

Ä 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 system will not boot the operating system.

Replace module with the correct
industry-standard device for the
computer. On some models, ECC
and non-ECC memory modules
cannot be mixed.
Use the Device Manager to check
memory configuration.
Check the application
documentation to determine the
memory requirements.
Check that the memory modules
have been installed correctly and
that proper modules are used.
No action required.
Delete any TSRs that you do
not need.
Check the memory requirements for
the application or add more
memory to the computer.
1. Reseat DIMMs. Power on the
system.
2. Replace DIMMs one at a time to
isolate the faulty module.
3. Replace third-party memory
with HP memory.
4. Replace the system board.
