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).

go/quickspecs
Do not intermix non-ECC memory DIMMs with ECC memory DIMMs.
●
CAUTION:
damage, align these guides properly when installing DIMMs.
HP ships only DIMMs that are electrically and thermally compatible with this
to find which DIMMs are compatible with the computer.
DIMMs and their sockets are keyed for proper installation. To prevent socket or DIMM
