DIMMs

Memory configurations

The server has 12 DIMM slots that support up to 96 GB maximum system memory. If you add or replace
memory modules, follow these guidelines:
•
You can install a maximum of 12 DDR3 240-pin RDIMMs (SR, DR, QR) or UDIMMs (SR, DR) slots (6
DIMMs per CPU).
•
Channel 0 is located farthest from the processor, followed by channel 1, and then channel 2.
•
Of the two DIMMs in a given channel, DIMM 0 is the farthest from the processor.
•
Each DIMM can have a maximum capacity of 16 GB.
•
CPU speed is 800 MHz, 1067 MHz, or 1333 MHz depending on DIMM population.
•
DIMM voltage is 1.5V and LV 1.35V.
•
All valid DIMM configurations are supported, provided the total node power is rated below the
maximum value.
Follow these guidelines when installing DIMMs in the server:
•
Install DIMMs in pairs while following the population rules listed in the following table.
•
Install DIMMs in decreasing capacity with the largest DIMMs installed in the banks farthest away from
each processor.
•
Use only HP DIMM part numbers listed in the server QuickSpecs.

The server memory protection mode is Advanced ECC memory. In Advanced ECC, the server does not fail
because of correctable memory errors. The server provides notification if the level of correctable errors
exceeds a predefined threshold rate. Advanced ECC provides additional protection over standard ECC,
because it is possible to correct certain memory errors that would otherwise be uncorrectable and result in a
server failure. For example, standard ECC can only correct single-bit memory errors, whereas Advanced
ECC can correct single-bit memory errors and multi-bit memory errors if all failed bits are on the same DRAM
device on the DIMM.

Installing a DIMM

CAUTION:
expansion slot covers, or blanks installed. If the server supports hot-plug components, minimize
the amount of time the access panel is open.
To install the component:
Power down the server (on page 17).
1.
Disconnect all peripheral cables from the server.
