A-Tech 4GB DDR4 2133MHz Desktop Module

This 4GB DDR4 module runs at 2133MHz with a CAS latency of CL15. It uses the standard 1.2V operating voltage and a 288-pin DIMM form factor. The unbuffered, non-ECC design fits typical desktop memory slots.

DDR4 2133 standard practical limits

The DDR4 2133 standard sets the baseline speed and voltage for this memory class. Systems that only support this frequency will not run the module faster, even if the platform allows higher data rates. Mixing with faster modules forces the entire kit to operate at 2133MHz.

Non-ECC unbuffered compatibility check

This module is built without error correction or registered buffering. It will only work in desktop platforms that accept non-ECC UDIMMs. Verify that your motherboard or Synology unit specifies non-ECC unbuffered support before installing.

Perguntas sobre este artigo

Will this 4 GB DDR4 module fit my Synology NAS that uses the D4N2133-4G part number?

Yes, the module is listed as a compatible equivalent for the Synology D4N2133-4G and matches the required 288-pin DDR4 2133 MHz specification

Does my desktop motherboard need to support ECC or registered memory for this RAM to work?

No, this is a non-ECC unbuffered DIMM, so it works in standard consumer desktop boards that accept regular DDR4 memory

What do the CL15 and 1.2 V ratings mean for everyday use?

CL15 is the CAS latency timing at 2133 MHz, and 1.2 V is the standard DDR4 operating voltage, giving normal power draw and response times for typical desktop workloads
