Server DDR4 ECC RDIMM

This 32GB registered DIMM runs at DDR4 2666 with CL19 latency and 1.2V operation. It is built as a compatible replacement for Cisco part numbers UCS-MR-X32G2RS-H and 15-105081-01. The module targets server and workstation systems that require error-correcting registered memory.

288-pin registered build

The 2Rx4 organization and major-brand chipset support data integrity under sustained loads. A 288-pin DIMM edge connector fits standard DDR4 RDIMM slots in qualified platforms. Registered buffering reduces electrical load on the memory controller when multiple modules are populated.

DDR4 2666 platform ceiling

The PC4-21300 rating defines the peak transfer rate for this generation. Systems limited to lower DDR4 speeds will downclock the module automatically. Capacity per slot is fixed at 32GB, so total memory depends on the number of supported DIMM sockets in the host.

Questions about this item

Does the DDR4 2666 RDIMM run at 2666 MT/s or drop to a lower speed?

The module is rated DDR4 2666 (PC4-21300) and will operate at 2666 MT/s when the platform supports that data rate.

Will this 288-pin DIMM fit a standard server DIMM slot?

Yes, it uses the 288-pin DDR4 DIMM form factor used by registered server memory slots.

Do I need to populate specific slots for the 2Rx4 registered module to work?

Install the RDIMM in the slots recommended by your server’s memory population guide; registered DIMMs often require a specific slot order per channel.
