Overview and Common Procedures—Server Upgrade

Memory DIMMs

Your system has 12 memory sockets for installing DDR SDRAM memory modules. Supported DIMM sizes are

256 MB, 512 MB, 1 GB, 2 GB and 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. The system supports combinations from 512

MB up to six GB in an HP 9000 rp3410 server and from one GB up to 32 GB in an HP 9000 rp3440 server. No

restrictions are applied to the use of 2-GB DIMMs. You can use 2-GB DIMMs together with other sizes (all

DIMMs of a quad must be equal) and you can create a 24-GB memory using 12 2-GB DIMMs.

NOTE If you are installing 4 GB DIMMs, you must upgrade the system firmware before DIMM

installation.
