16GB DDR4 2933MHz ECC RDIMM Server Module

This 16GB registered DIMM uses DDR4 technology at 2933MHz with ECC error correction. It is built for servers and workstations that require registered memory for stable operation under continuous workloads.

Registered ECC RDIMM 2Rx8 CL21 1.2V

The module is a registered ECC RDIMM with a 2Rx8 organisation, CL21 latency and standard 1.2V operation. Systems must support registered ECC DDR4 DIMMs; desktop boards that accept only unbuffered non-ECC memory cannot use this part.

16GB Single Module Capacity Headroom

A single 16GB module adds substantial capacity for virtualisation, database caching and multi-user applications. Workloads that exceed 16GB per channel or require higher frequencies than 2933MHz will need additional modules or a faster memory tier.

Questions about this item

What does 2933 MHz mean for real-world throughput in a server?

The module transfers data at 2933 MT/s, so a dual-channel server sees roughly double that rate and a quad-channel system roughly quadruple it, scaling with the number of populated channels.

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

The registered DIMM tops out at the rated 2933 MT/s; the memory controller cannot push it beyond that without overclocking, which most server BIOSes disable.

Will this 288-pin RDIMM fit my 1U rack chassis?

The stick uses the standard 288-pin DDR4 DIMM form factor, so it fits any server or workstation board with DDR4 RDIMM slots regardless of chassis height.
