Specifications
Memory
This section presents memory module (DIMM) configuration information and removal/installation
procedures.
Supported DIMM configurations
The computer supports these DIMM configurations:
●
Four DIMM slots
●
Memory configuration from 1 GB to 16GB
●
No support for mirroring
●
No support for DIMM sparing
●
Error checking and correcting (ECC) and non-ECC DIMMs are supported.
DIMM installation guidelines
●
Install only HP-approved DDR3 DIMMs
CAUTION: HP ships only DIMMs that are electrically and thermally compatible with this
computer. Because third-party DIMMs might not be electrically or thermally compatible, they are
not supported by HP.
●
For ECC DIMMs, use only industry-standard ECC unbuffered DIMMs. See
http://www.hp.com/
go/quickspecs to find which DIMMs are compatible with the computer.
●
Do not intermix non-ECC memory DIMMs with ECC memory DIMMs.
DIMM installation order
The numbers in the following figure show the correct installation order for DIMMs.

BIOS errors and warnings
The BIOS generates warnings/errors on invalid memory configurations:
●
If the BIOS can find a valid memory configuration by disabling plugged-in memory, it does so and
reports a warning during POST. the computer can still be started. The warning will indicate the
location of the failed DIMM on the system board or memory riser.
●
If there is no way for the BIOS to obtain a valid memory configuration by disabling plugged-in
memory, the BIOS halts with a diagnostics code for memory error (five beeps and blinks).
