System will not boot or does not function properly after installing additional memory modules.

Cause Solution

A memory module is not installed in the DIMM1 or XMM1 socket. Ensure 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.

Memory module is not the correct type or speed grade for the

system or the new memory module is not seated properly.

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.

Cause Solution

You have run out of memory to run the application. Check the application documentation to determine the memory

requirements.

Memory count during POST is wrong.

Cause Solution

The memory modules may not be installed correctly. Check that the memory modules have been installed correctly and

that proper modules are used.

Integrated graphics may use system memory. No action required.

Insucient memory error during operation.

Cause Solution

Too many Terminate and Stay Resident programs (TSRs) are

installed.

Delete any TSRs that you do not need.

You have run out of memory for the application. Check the memory requirements for the application or add more

memory to the computer.

Power LED ashes Red ve times, once every second, followed by a two second pause, and the computer beeps ve times. (Beeps

stop after fth iteration but LEDs continue ashing.)

Cause Solution

Memory is installed incorrectly or is bad. 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.
