Installing Additional System Memory
The server has 12 memory sockets for installing DDR SDRAM memory modules. System memory DIMMs are
located on the system board.
WARNING
Ensure that the server is powered off and all power sources have been disconnected
from the server prior to removing or replacing system memory.
Voltages are present at various locations within the server whenever an ac power
source is connected. This voltage is present even when the main power switch is in
the off position.
Failure to observe this warning can result in personal injury or damage to
equipment.
CAUTION
Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD
safety precautions can result in damage to the server.
Supported DIMM Sizes
Supported DIMM sizes are as follows:
•
256 MB
•
512 MB
•
1 GB
•
2 GB)
•
4 GB (HP 9000 rp3440 only). If 4 GB DIMMs are used, only one configuration (8 X 4 GB in the first eight
sockets) is supported.
Dissimilar DIMM sizes can be used across the entire system board (except when 4 GB DIMMs are used) but
both DIMMs in a pair (first group of four, connectors 0A and 0B of HP 9000 rp3410) and all four DIMMs of
any quad must be identical.
