Bios Errors And Warnings; Dimm Installation Guidelines; Dimm Installation Order - HP Z1 G2 Maintenance And Service Manual

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:
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. Go to
quickspecs
● 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.

CAUTION: Internal components might be powered even when the computer is off. To prevent damage,
