BIOS errors and warnings
The BIOS generates warnings/errors on invalid memory congurations:
●
If the BIOS can nd a valid memory conguration 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 conguration by disabling plugged-in memory,
the BIOS halts with a diagnostics 2006 code for memory error (ve 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 workstation.
Because third-party DIMMs might not be electrically or thermally compatible, they are not supported by
HP.
●
Install only HP-approved DDR3 DIMMs. See http://www.hp.com/go/quickspecs to nd DIMMs that are
compatible with the workstation.
●
Do not intermix DIMMs of dierent technologies. ECC Unbuered DIMMs (UDIMMs), Registered DIMMs
(RDIMMs), and Load Reduced DIMMs (LRDIMMs) are supported on your workstations. Supported DIMM
congurations on page 53 species which technologies are supported on each platform.
CAUTION: DIMMs and their sockets are keyed for proper installation. To prevent socket or DIMM damage,
align these guides properly when installing DIMMs.
