A-Tech 16GB DDR4 2133MHz ECC UDIMM

This 16GB DDR4 module runs at 2133MHz with CL15 latency and operates at 1.20V. It uses a 2Rx8 unbuffered ECC design built with major-brand chips. The 288-pin DIMM fits standard server and workstation slots. It is a compatible replacement for the Synology RAMEC2133DDR4-16G part.

DDR4 2133MHz ECC UDIMM practical limits

DDR4 2133MHz PC4-17000 ECC UDIMM modules require a platform that supports unbuffered ECC memory at this speed and voltage. The system must accept 2Rx8 organisation and 1.20V operation. Registered or load-reduced DIMMs will not work in the same slots. Mixing non-ECC or different-rank modules can disable error correction or prevent boot.

Check your system before ordering

Verify that your motherboard or NAS lists support for 16GB DDR4 2133MHz ECC UDIMM 2Rx8 modules at 1.20V. Confirm the maximum capacity per slot and the total number of available 288-pin slots. Ensure the BIOS or firmware is current enough to recognise this density and rank configuration. Buyers who need registered ECC or higher-speed modules should look elsewhere.

Questions about this item

Should I choose the 16GB module or a smaller capacity for my Synology?

The 16GB module matches the RAMEC2133DDR4-16G specification exactly; select it when your system requires that capacity and has a free 288-pin slot.

What does the 2133MHz rating deliver in a real server?

It runs at 2133MHz with CL15 timing and 1.2V, providing DDR4 17000 bandwidth for ECC error correction in compatible Synology units.

Is this DDR4 ECC UDIMM compatible with standard 288-pin DDR4 slots?

Yes, it is a 288-pin DDR4 ECC UDIMM operating at 1.2V, designed for unbuffered DDR4 slots that support ECC memory.
