Memory Configuration Guidelines
Memory Configuration and SIMM Installation
Memory in HP 3000 and HP 9000 servers can be added in many different megabyte combinations
depending on your model, your use of existing memory, your memory upgrade goals, and what
combination of memory modules you install.
The configuration guidelines presented in this chapter will successfully optimize most combinations of
memory modules. It is still possible, however, when adding memory to already-configured memory on two
extenders, to meet these guidelines and still generate a warning that your memory is not optimized. If that
happens, remove all memory modules from both extenders and re-install them following the guidelines
provided below.
Before You Begin
Before you begin, you should understand the following definitions:
A SIMM is a single memory Printed Circuit Assembly (PCA) or memory board. SIMMs have memory on
one side of the PCA only. All SIMMs have their size marked on the board near the upper left corner.
A DIMM is a single memory PCA with memory on both sides of the PCA. All DIMMs have their size
marked on the board near the upper left corner, also.
Note
Regardless of the availability of SIMM slots, the total amount of memory you can install is dependent
on your system model and your operating system. Refer to your system Owner’s Guide.
Note
The acronym SIMM is used throughout this document to indicate either SIMM or DIMM
