Memory matched to Cisco UCS OEM part numbers. If you have a UCS-MR-X or UCS-ML code off a Cisco quote, a spec sheet, or a module already in the chassis, this is where you find the compatible equivalent — same density, same rank, same speed, without Cisco's memory pricing.
The cross-reference covers Cisco part numbers across all UCS server models, spanning B-Series blades and C-Series rack servers from M2 through M5. All modules are registered ECC RDIMM or load-reduced LRDIMM, DDR4 and DDR3, from 8GB up to 256GB per module, at 1333MHz through 3200MHz.
Cisco encodes the module type into the part number itself: UCS-MR- is registered, UCS-ML- is load-reduced, and the trailing code carries rank and speed — X32G2RW is a 32GB 2-rank DDR4-3200, X64G4RS-H a 64GB 4-rank. Those are not interchangeable, and a UCS chassis is unforgiving about mixing rank configurations across a channel.
