Memory Configuration Guidelines C-5
Procedure for Single Memory Extenders — Detailed
Step 1. Remove any modules pairs from the memory extender.
Step 2. Combine the removed and new memory modules and organize them into four groups:
• 512MB modules
• 256MB modules
• 128MB and 64MB modules (combined in the same group)
• 32MB modules
Step 3. From each memory group, create as many pairs of modules (sets of 4 SIMMs) as possible. A
128MB module and a 64MB module can be used as a pair of modules since they are from the
same group. Set aside any remaining modules of each size for installation last. Remember, each
module consists of 2 same-size SIMMs. Any remaining single SIMMs are "unusable."
Step 4. Locate and identify each available slot by its slot number and letter (e.g., 0a, 0b) on the memory
extender. Identify the sequence of available slots from lowest to highest.
Step 5. Install any pairs of modules (sets of 2 modules) first.
A. Install pairs of modules in decreasing size: start with the largest memory size and end with the
smallest. Within a mixed-group of 128MB and 64MB modules, install the 128MB modules first.
B. Install pairs of modules beginning with the lowest available slot number, then the next higher slot
number. In an empty extender, for example, the first pair of modules will go in slots 0a/0b and 1a/1b;
the next in 2a/2b and 3a/3b, and so on.
Step 6. Install any remaining modules, starting with the largest memory size first.
Note
Even though 128MB modules and 64MB modules are in the same group, the SIMMs for each module
size cannot be mixed, i.e., do not combine a 64MB SIMM and a 32MB SIMM as one module.
