Product Description
IBM 3022 128MB Main Storage DIMM
128MB Main Storage DIMM (feature code 3022), a proprietary DRAM memory module designed for capacity expansion in older IBM iSeries/AS/400e and select Power Systems servers. This ECC DIMM provides 128 MB of main storage per module, manufactured to IBM specifications for reliable operation in mission-critical legacy environments running AIX or IBM i (formerly OS/400). It is a plug-in module for compatible processor or memory riser slots, often requiring installation in pairs or specific configurations to maintain system balance and performance.
This older-generation memory supports upgrades, replacements, or preventive maintenance on discontinued platforms like iSeries Models 250, 270, and 810.
Key Specifications
| Specification | Details |
|---|---|
| Capacity | 128 MB per DIMM |
| Memory Type | Main Storage DIMM (DRAM, ECC) |
| Form Factor | Proprietary IBM DIMM (legacy slot-specific) |
| Feature Code / Part Number | 3022 |
| Installation Rules | Often in pairs (e.g., Model 250 plugs directly into processor); cannot mix with certain other features like #3029 in pairs/quads |
| Compatibility Notes | Verify system model, slot type, firmware, and max memory config before use |
Configuration Options
No specific bundles or additional feature codes are detailed on the DataTech page beyond the base module (3022). Use standard IBM-compatible practices:
- Installation: Add in pairs/quads as required by model (e.g., sequential order without gaps on risers)
- Mixing: Avoid mixing with dissimilar capacities/technologies in same bank/group
- Other: Compatible only with listed legacy models; no modern upgrades or adapters
These guidelines ensure stable operation in supported legacy setups.
Compatibilities
The IBM 3022 128MB Main Storage DIMM is compatible with select legacy IBM systems:
- Models: iSeries/AS/400e Models 250, 270, 810 (9406 series); specific processor features (e.g., #2248, #2250, #2252, #2253, #2422-#2454 on Model 270; #2469 on Model 810).
- Operating Systems: IBM i (OS/400 V4R3+), AIX on compatible Power processors.
- Installation Notes:
- Model 250: Plugs directly into processor; added in pairs; max 6 modules.
- Model 270: Supported on listed processors; on some (#2434/#2454) only #3022 allowed.
- Model 810: Supported on specific processors (e.g., 2-way 2700 CPW).
- Restrictions: Cannot mix in pairs/quads with #3029; requires matching configurations for balance; not compatible with modern Power Systems or non-listed models.
This ensures reliable memory expansion in older iSeries/AS/400e environments.
The unit comes with a 60-day warranty for added assurance.
