System setup utility reports unprogrammed EEPROM Use this information to troubleshoot the computer. Cause Unprogrammed EEPROM. Solution Contact an authorized service provider. Solving memory problems If you encounter memory problems, some common causes and solutions are listed in these tables. IMPORTANT: Power can 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 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.

Solution Verify that a memory module is installed in the DIMM1 or 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. Out of memory error Use this information to troubleshoot the computer. Cause You have run out of memory to run the application. Solution Check the application documentation to determine the memory requirements. Memory count during POST is wrong Use this information to troubleshoot the computer. Cause The memory modules might not be installed correctly. Solution Check that the memory modules have been installed correctly and that proper modules are used. 52 Chapter 5 Troubleshooting without diagnostics

Unprogrammed EEPROM.
Solving memory problems
If you encounter memory problems, some common causes and solutions are listed in these tables.
IMPORTANT:
Power can 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 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

Use this information to troubleshoot the computer.
Solution
Cause
Verify that a memory module is installed in the DIMM1 or XMM1 socket on the
system board. This socket must be populated with a memory module.
A memory module is not installed in the DIMM1
or XMM1 socket.
Replace module with the correct industry-standard device for the computer.
