Cisco HX220c M5 compatible DDR4 RDIMM

This 16 GB DDR4 2933 MHz registered ECC module is built for the Cisco HyperFlex HX220c M5 server. The 1Rx4 organisation and CL21 latency suit enterprise workloads that demand error correction and signal stability. It operates at 1.2 V and uses the standard 288-pin RDIMM form factor.

Verify registered ECC support

Confirm the server BIOS recognises registered ECC DDR4 RDIMMs and check the memory population guide for the HX220c M5 before ordering. The module runs at DDR4 2933 (PC4-23400); mixing speeds or ranks may force the channel to a lower rate. Ensure the system requires 1.2 V operation.

Plain green PCB with major-brand DRAM chips

Samsung, Micron or Hynix ICs are used without a heat spreader, relying on server chassis airflow for cooling. The 288-pin RDIMM edge connector keys only into registered DDR4 slots, preventing accidental insertion into unbuffered or UDIMM sockets. Single-rank 1Rx4 layout helps signal integrity in dense configurations.

Questions about this item

Does the package contain a single 16 GB module or the full 192 GB kit?

The listing describes a 192 GB kit made up of twelve 16 GB DDR4 2933 ECC RDIMM modules.

Should I choose the 1Rx4 CL21 variant or a different rank and latency?

This module is 1Rx4 with CL21 at 2933 MT/s; select it when your Cisco HX220c M5 requires that exact rank and timing.

Will the 2933 MT/s speed run at that rate in my HX220c M5?

The module is rated DDR4 2933 PC4-23400; the server’s memory controller will set the final operating speed.
