The HP Z1 Workstation has 4 DIMM slots and supports up to 32 GB ECC or 8 GB non-ECC unbuffered
DDR3 1600 MHz memory.

Four DIMM slots
●
Maximum capacity: 32 GB
●
Error checking and correcting (ECC) and non-ECC DIMMs only.
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 workstation can still be started. The warning will indicate the
location of the failed DIMM on the system board.
●
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 2006 code for memory error (five beeps and blinks).
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.
CAUTION: DIMMs and their sockets are keyed for proper installation. To prevent socket or DIMM
damage, align these guides properly when installing DIMMs.
