Load-reduced (LRDIMM) memory for Cisco UCS servers: the module type that reaches the largest capacities, up to 256GB per module, on DDR4 and DDR3 Cisco platforms from M3 through M6. To find yours, type your server model (for example C240 M5) or your Cisco part number (for example UCS-ML-128G4RW) into the search bar at the top of the page. Cisco load-reduced part numbers start with UCS-ML.
This collection holds two kinds of listings. Server listings (titled "Cisco UCS" + model) are matched to one UCS model and offer every supported size in single modules and matched kits. Part-number listings (titled with a Cisco PID such as UCS-ML-X64G4RT-H) are matched to one Cisco memory part number: use them when you are replacing or adding to modules you already have, or ordering from a Cisco quote.
Do not mix: a Cisco UCS server runs either LRDIMMs or RDIMMs, never both. Match the type already installed; if your server has registered modules (UCS-MR parts), see DDR4 Cisco memory.
When to choose LRDIMM: for the highest total capacity, using 128GB and 256GB modules. On M5 servers these need 2nd Gen Xeon Scalable processors.
DDR5 servers: Cisco UCS M7 and M8 servers use DDR5 RDIMMs; see DDR5 Cisco memory.
