Troubleshooting Without Diagnostics
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.
Solving Memory Problems
Problem Cause Solution

does not function properly
after installing additional
memory modules.
A memory module is
not installed in the
XMM1 socket.
Ensure that a memory module is
installed in the black XMM1 socket

must be populated with a memory
module.

during operation.
Too many Terminate
and Stay Resident
programs (TSRs) are
