Supported DIMM Sizes
Supported DIMM sizes are 256 MB, 512 MB, 1 GB, 2 GB (HP 9000 rp3440 only), and 4 GB (HP 9000 rp3440
only). If 4 GB DIMMs are used (HP 9000 rp3440), only one configuration (8 X 4 GB in the first eight sockets)
is supported. Dissimilar DIMM sizes may 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.
