Solving Memory Problems - HP Compaq dx7300 MT Reference Manual

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.
✎
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.

Troubleshooting Without Diagnostics
Solution
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.
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.
