Server-grade DDR4 RDIMM

This 16GB DDR4 2933 module is built for server and workstation platforms that require registered ECC memory. The single-rank 1Rx4 design and 1.20V operation match standard DDR4 voltage for compatible systems. It serves administrators and integrators who need dependable capacity upgrades for qualified hardware.

Fits registered DIMM slots

The 288-pin RDIMM form factor installs only in motherboards that support registered ECC DDR4 at the specified speed and voltage. Registered buffering reduces electrical load on the memory controller, which helps stability when multiple modules are populated. Systems without registered DIMM support cannot use this module.

Lifetime warranty and US support

A-Tech backs every order with a lifetime warranty and provides complimentary United States-based technical support before, during, and after purchase. All modules undergo quality assurance testing to verify reliable performance. This coverage assists builders who want direct assistance if compatibility questions arise.

Questions about this item

Will the 1Rx4 registered design limit capacity scaling on my four-channel server board?

Each module is a single-rank 1Rx4 registered DIMM, so you can populate all four channels per CPU without hitting the rank-per-channel limit that dual-rank modules would impose.

How much heat and power does a 1.20 V DDR4 2933 RDIMM add under continuous load?

At the standard 1.20 V DDR4 voltage the module draws minimal power and produces little heat, letting it run all day in a cooled server chassis without extra airflow.

My motherboard has 288-pin DDR4 slots — is anything else required for this ECC RDIMM to work?

You need a server or workstation platform that supports ECC registered DDR4 memory; consumer desktop boards will not initialise the module.
