OWC 16GB DDR4 2933MHz ECC RDIMM

This module provides 16GB of DDR4 ECC registered memory rated at 2933MHz with CL21 latency. It is designed for server and workstation platforms that require registered DIMMs. The part is validated for Supermicro X11SPi-TF, X11SPL-F, X11SPM-F, X11SPM-TF and X11SPM-TPF motherboards. It will not work in standard desktop computers.

Verify registered DIMM support before ordering

Confirm that your motherboard accepts 288-pin DDR4 registered ECC modules and that the CPU memory controller supports 2933MHz operation. The module runs at 1.2V and is backward compatible with 2133MHz, 2400MHz and 2666MHz speeds. Registered memory cannot be mixed with unbuffered memory in the same system.

Low-profile design without heat spreader

The 288-pin RDIMM lacks a heat spreader, keeping the height low for dense server chassis. Gold-edge connectors meet JEDEC and RoHS specifications for reliable insertion. The 2Rx8 rank organisation suits multi-channel server configurations. OWC tests every module in-house before shipment.

Questions sur cet article

Does the 16GB DDR4 2933MHz ECC Registered RDIMM ship alone or as a kit?

The module is sold as a single 16GB stick; add more sticks to reach the capacity your Supermicro board supports.

Should I pick the 2933MHz CL21 version or a slower speed for my X11SPM-F?

Choose this 2933MHz CL21 module; it runs at 2933MHz and also works at 2666MHz, 2400MHz and 2133MHz if the system requires it.

Will the advertised 2933MHz speed actually run at that rate in my Supermicro X11SPi-TF?

Yes, the board supports 2933MHz DDR4, so the module operates at its rated 2933MHz CL21 without manual tuning.
