64GB ECC RDIMM for Cisco M5 servers

This single 64GB DDR4 2933 module delivers registered ECC memory for Cisco HX220c M5, HX240c M5, HXAF220c M5, HX-E-220M5SX and C480 ML M5 systems. It targets IT teams maintaining or expanding these specific server platforms where data integrity and registered buffering are required.

Sustained operation at 2933MHz with CL21 latency

The module runs at a steady 1.2V and is validated for continuous server workloads rather than short bursts. Backward compatibility with 2133MHz, 2400MHz and 2666MHz buses lets it slot into existing configurations without forcing a full memory refresh across every slot.

Verify registered ECC requirement

This RDIMM will not work in standard desktop boards or in systems that only accept unbuffered or load-reduced ECC memory. Confirm your Cisco model appears in the supported list and that a free 288-pin DDR4 slot is available before ordering.

Questions sur cet article

How much power does this 1.2V DDR4 ECC RDIMM draw under continuous server load?

The module runs at 1.2 volts, the standard DDR4 voltage, which keeps power draw low during all-day operation in Cisco HX220c M5, HX240c M5, HXAF220c M5, HX-E-220M5SX or C480 ML M5 servers.

What must my system already have to accept this 288-pin registered ECC DIMM?

A server or workstation motherboard with DDR4 RDIMM slots that supports 2Rx4 registered ECC memory — such as the listed Cisco HX and C480 M5 platforms — and an available 288-pin DIMM socket.

Will this 2933 MHz CL21 module run stably alongside existing 2666 MHz DDR4 RDIMMs in my Cisco server?

Yes, the spec sheet confirms backward compatibility with 2133, 2400 and 2666 MHz speeds, so the module will downclock to match the slowest installed DIMM while maintaining ECC registered operation.
