The HMCT04AGERA is an SK Hynix 128GB DDR5 registered DIMM rated at 5600MT/s, built on A-die silicon. It is a 288-pin 4Rx4 module operating at 1.1V, supplied in trays of 50. The four-rank organisation packs twice the rank depth of a standard dual-rank module, which is how the HMCT04AGERA reaches 128GB on a single DIMM.

128GB RDIMMs are bought when memory capacity per socket is the binding constraint rather than cost per gigabyte: in-memory databases and analytics, large-scale virtualisation and consolidation, HPC nodes, and AI training and inference hosts feeding accelerators from system memory. The HMCT04AGERA fills a channel with four ranks, so platform support and per-channel population rules should be checked against the server's memory reference guide before specifying it. The x4 organisation supports the stronger ECC and device-correction modes enterprise platforms rely on. Buyers are typically server OEMs, hyperscale and enterprise datacenter operators, system integrators and memory channel distributors.
