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

Because third-party DIMMs might not be electrically or thermally compatible, they are not supported by
