HP Z238

◦
Connect a media card reader USB cable to the USB connector on the system board labeled MEDIA. If
the media card reader has a 1394 port, connect the 1394 cable to the 1394 PCI card.
Drive installation and cabling scenarios
This section presents cabling guidelines for the most common maximum storage congurations. If you add or
remove drives, HP recommends you follow these guidelines for highest drive performance and ecient cable
routing.

Memory
Supported DIMM congurations
●
Four DIMM slots
●
Unbuered ECC/nECC DIMMS only
●
Maximum capacity: 64 GB
NOTE: Mirroring and DIMM sparing are not supported.
BIOS errors and warnings
The BIOS generates warnings/errors on invalid memory congurations:
●
If the BIOS can nd a valid memory conguration 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 conguration 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 dierent technologies. ECC Unbuered DIMMs (UDIMMs), Registered DIMMs
(RDIMMs), and Load Reduced DIMMs (LRDIMMs) are supported on your workstations. Supported DIMM
congurations on page 44 species 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.
