IBM 53P3226 server / storage / networking hardware Server Hardware / Parts

The IBM 53P3226 is a 512MB PC2100 DDR-266MHz registered ECC DIMM, 208-pin, supplied as part of IBM feature #4452, a 2GB (4x512MB) memory kit for pSeries POWER4-generation systems. Fitted in matched sets to populate a system’s memory subsystem, DIMMs of this specification are required to restore full memory capacity after a module failure or to bring a system back to a validated configuration, since pSeries memory of this era generally requires matched pairs or quads for correct interleaving. POWER4-generation pSeries systems remain in service across a number of established enterprise Unix deployments, and genuine, correctly speed-matched DIMMs such as this one are a routine maintenance requirement on hardware that predates newer memory generations. Specifiers should confirm their system’s exact memory population rules before ordering. Tech-Star (UK-based, shipped worldwide) supplies the 53P3226 for engineers maintaining pSeries memory capacity.
