OWC 2R9D42R816GB 16GB DDR4 2933MHz CL21 ECC RDIMM Server Memory Upgrade

SKU CH-QJTE-7001R

16GB DDR4 2933MHz ECC registered DIMM for compatible Supermicro server motherboards

  • Capacity16GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes

Capacity 16GB

  • ECC registered design protects data integrity in servers
  • 16GB capacity expands memory for demanding workloads
  • DDR4 2933MHz CL21 speed matches system specifications
  • 2V operation reduces power draw per module
  • Validated for Supermicro X11DPF and X11DPG motherboards

Server ECC RDIMM upgrade

This 16GB DDR4 2933MHz CL21 registered DIMM is built for Supermicro X11DPF and X11DPG motherboards. It targets administrators who need error-correcting memory in 288-pin slots and cannot use unbuffered desktop modules.

Capacity and headroom

The single 16GB rank 2Rx8 module runs at 1.2V and steps down to 2133MHz, 2400MHz or 2666MHz when the platform requires it. Headroom ends at the registered ECC ceiling; workloads that demand higher density per slot or unbuffered operation will not be served.

Build and connectors

A plain green PCB without a heat spreader fits tight server chassis and standard 288-pin RDIMM sockets. The registered buffer adds one clock cycle of latency but keeps signal integrity stable across fully populated channels in rackmount and workstation boards.

Klausimai apie šią prekę

Will this 2933MHz CL21 ECC RDIMM run with my existing 2666MHz DDR4 modules?

The module is backward compatible with 2133MHz, 2400MHz and 2666MHz DDR4 speeds, so it will run at the speed of the slowest installed module.

How can I confirm the 16GB 2Rx8 RDIMM is detected and ECC is active after installation?

Enter the server BIOS or UEFI and verify the total memory shows 16GB per module with ECC status reported as enabled or active.

Does the 288-pin 1.2V RDIMM ship with a heat spreader or any cables I need to buy separately?

The module has no heat spreader and requires no additional cables; only the RDIMM itself is included.
