iSeries 9406 Memory, #3093 512 MB Main Storage 520/550/800/810
The #3093 - 512 MB Main Storage DIMM (DDR - 256 Mb technology, unstacked) provides 512 MB of Main Storage for the following systems.
For a Model 520: Supported on the #8950, #8951, #8952, #8953, #8954 and #8955 processors. Install DIMMs in sets of four (quads) with one exception: A single pair of 256 MB DIMMs is allowed on the #8950 processor. Add an additional pair of 256 MB DIMMs to the original pair (to make a quad) whenever more DIMMs are added. Then one additional quad of DIMMs can be added to the system. For the #8950 processor, the first DIMM pair goes into DIMM slots J0A and J2A. The second pair of DIMMs goes into slots J0C and J2C. The first quad of DIMMs is plugged into DIMM slots J0A, J2A, J0C, and J2C. The second quad of DIMMs is plugged into DIMM slots J0B, J2B, J0D, and J2D.
For a Model 550: Supported on the #8958 processor. Install DIMMs in sets of four (quads). The 550 has two processor cards and best memory access performance is achieved when memory is balanced on each processor card: Plug the first quad of memory modules into memory module slots P1-C8-C1, P1-C8-C3, P1-C8-C6, and P1-C8-C8 on each processor card, or slots P1-C9-C1, P1-C9-C3, P1-C9-C6, and P1-C9-C8 on each processor card. Plug the second quad of memory modules into memory module slots P1-C8-C2, P1-C8-C4, P1-C8-C5, and P1-C8-C7 on each processor card or, slots P1-C9-C2, P1-C9-C4, P1-C9-C5, and P1-C9-C7 on each processor card.
For a Model 800: Supported on the #2463 and #2464 processors. A single main storage DIMM feature is allowed on Model 800 processors. When the total number of main storage DIMMs is increased greater than one, the single existing DIMM must be paired up with a DIMM of the same capacity. Any additional DIMMs must be added in pairs of the same capacity. Eight memory DIMM slots are available in the base system for main storage DIMMs, which plug directly onto the backplane.
For a model 810: Supported on the #2465, #2466, and #2467 processors. A single main storage DIMM feature is allowed on Model 810 processors. When the total number of main storage DIMMs is increased greater than one, the single existing DIMM must be paired up with a DIMM of the same capacity. Any additional DIMMs must be added in pairs of the same capacity. Eight memory DIMM slots are available in the base system for main storage DIMMs, which plug directly onto the backplane.
Minimum operating system level: OS/400 V5R2
