16GB DDR4 ECC RDIMM for servers

This 16GB DDR4 module runs at 2933MHz with CL21 latency and 1.20V operation. It is a registered DIMM with ECC and a 2Rx8 organisation, built for server and workstation platforms that require error-correcting registered memory. The 288-pin form factor matches standard DDR4 DIMM slots in compatible systems.

Registered DDR4 limits at 2933MHz

Registered DIMMs add a clock cycle of buffering, so the memory controller must support registered operation and the specific 2933MHz data rate. Mixing registered with unbuffered modules will prevent boot, and populating all slots may force the controller to drop below the rated speed. Verify the platform’s qualified vendor list before installation.

Major-brand chips on a 288-pin RDIMM

The module uses major-brand DRAM components assembled to a standard 288-pin registered DIMM PCB. Gold-edge contacts resist oxidation in continuously powered racks, and the registered buffer reduces electrical load on the memory bus. The single-module 16GB capacity lets you fill slots incrementally without exceeding per-channel rank limits.

Questions about this item

Should I choose the 16GB DDR4 2933MHz ECC RDIMM or a different capacity for my server?

This module provides 16GB in a single 2Rx8 registered DIMM; select it when your system requires one 16GB stick at DDR4 2933MHz with ECC and registered buffering.

What does the DDR4 2933MHz (PC4-23400) rating deliver in an actual server?

The module runs at 2933MHz with CL21 latency at 1.20V, providing ECC error correction and registered signal buffering for stable operation in compatible server and workstation platforms.

How does the 288-pin DDR4 RDIMM interface limit performance in practice?

The 288-pin registered DIMM form factor operates at the DDR4 2933MHz standard with CL21 timing and 1.20V; maximum throughput is determined by the platform's memory controller and channel population.
