Cisco Compatible 32GB DDR4 2666 RDIMM

This module delivers 32GB of registered ECC memory built to Cisco UCS specifications. It operates at 2666 MT/s with CL15 latency and runs at 1.2V using a 2Rx4 organisation. The 288-pin DDR4 form factor fits servers that require registered DIMMs with error correction.

Suitable for Cisco UCS memory upgrades only

This part matches the Cisco UCS-MR-X32G2RS-H part number for direct replacement or capacity expansion. It is not for systems that require unbuffered UDIMMs, load-reduced LRDIMMs, or a different DDR generation. Buyers who need non-ECC memory or a different voltage should look elsewhere.

Registered ECC with 2Rx4 organisation

The registered buffer and ECC logic ensure data integrity and signal stability in multi-DIMM server configurations. The dual-rank x4 layout supports higher density per channel compared to single-rank alternatives. Verify that your platform accepts registered ECC RDIMMs before purchasing.

Questions about this item

Does the 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR4 RDIMM matches the standard server DIMM slot for this form factor.

What BIOS setting must be enabled for the registered ECC module to initialise correctly?

Ensure the memory mode is set to registered ECC so the 2Rx4 module initialises at 2666 MT/s with CL15 timing.

When should the 32 GB DDR4 module be replaced to maintain ECC integrity?

Replace the module if the system logs report uncorrectable ECC errors or if the module fails a full memory diagnostic test.
