8GB DDR4 ECC UDIMM for servers

This A-Tech module provides 8GB of DDR4 2133 ECC unbuffered memory in a single 288-pin DIMM. It operates at CL15 latency with a standard 1.2V voltage and uses a 2Rx8 rank configuration. The module is built with major brand chips and designed for server and workstation systems that require error-correcting code memory.

Suits Synology NAS upgrades and ECC workstations

This memory suits administrators upgrading a Synology system using the RAMEC2133DDR4-8G part or any platform that accepts DDR4 2133 ECC UDIMM modules. It is not for builds that need registered or load-reduced DIMMs, nor for consumer boards that only support non-ECC memory. Buyers who want higher capacities or faster speeds must select different modules.

Check motherboard ECC UDIMM support first

Verify that your motherboard or NAS explicitly supports DDR4 2133 ECC unbuffered DIMMs and accepts a 2Rx8 organisation. Confirm the maximum memory per slot and the total number of available 288-pin slots. Ensure the system BIOS or firmware is updated to recognise the module capacity and ECC functionality.

Questions about this item

What type of memory slot must my motherboard have to accept this 288-pin DDR4 module?

Your motherboard needs a DDR4 UDIMM slot with 288 pins; the module is unbuffered ECC and runs at 1.2 V.

Will this ECC UDIMM work in a system that currently uses non-ECC DDR4 memory?

Most consumer boards disable ECC when non-ECC modules are present, so the error-correction feature would not be active.

How can I confirm the module is running at 2133 MHz with CL15 timing after installation?

Check the memory speed and CAS latency in the BIOS or a system-information tool; they should show 2133 MHz and CL15.
