Memory

This workstation has 16 memory slots, labeled 0A, 0B through 7A, 7B. Memory can
be configured from 32 MB to 2 GB (3.2 GB on J2240 only or 4 GB if you are run-
ning HP-UX 11.x). Memory can be configured in combinations of pairs of 32 MB,
128 MB and 256 MB DIMM pairs. Memory DIMMs must be installed in pairs of
equal size, with 256 MB DIMM pairs installed first, followed by 128 MB, then 64
MB and finally, 32 MB DIMM pairs. Figure 3–11 gives the recommended order for
installing pairs of DIMMs.

NOTICE:
Any combination of memory may be used although,
for maximum performance, the use of common-sized
memory boards is recommended; either all 32 MB,
128 MB, or 256 MB board pairs. Therefore, users
who wish to achieve both maximum performance and
maximum future capacity are advised to use 256 MB
board pairs exclusively.
See chapter 5 of this manual for details on installing memory modules.
