4GB DDR4 2133MHz ECC RDIMM

This 4GB DDR4 2133MHz ECC RDIMM module is built for servers and workstations that require registered, error-correcting memory. It suits administrators upgrading compatible Samsung M393A5143DB0-CPB slots or expanding capacity in systems qualified for PC4-17000 registered DIMMs.

Registered 288-pin DIMM with 1.20V operation

The registered 288-pin DIMM design adds a buffer that reduces electrical load on the memory controller, a requirement for many multi-module server boards. Operating at the standard 1.20V DDR4 voltage, the module fits existing power budgets without extra cooling considerations.

Major-brand chips tested for compatibility

A-Tech assembles the module with major-brand chips and validates each unit through quality-assurance testing to confirm reliable operation in qualified platforms. The bundled lifetime warranty and US-based technical support provide a direct path for verification assistance if compatibility questions arise during installation.

Questions about this item

What DDR4 speed does this PC4-17000 ECC RDIMM run at?

The module operates at DDR4 2133 MHz, which corresponds to the PC4-17000 data-rate standard.

Will this 288-pin registered DIMM fit my server's memory slots?

Yes, it uses the standard DDR4 DIMM 288-pin form factor and requires a motherboard that supports registered ECC memory.

Do I need to change any BIOS settings when installing this 1Rx8 registered module?

Install the module with the system powered off; most servers auto-detect registered ECC RAM, but verify the memory mode is set for registered operation if the BIOS offers a choice.
