A-Tech 16GB DDR4 2133MHz CL15 ECC SODIMM 260-Pin 1.2V Synology RAMEC2133DDR4SO-16G

16GB DDR4 2133MHz ECC SODIMM for Synology

This 16GB DDR4 2133MHz CL15 ECC SODIMM module is built for Synology systems using the RAMEC2133DDR4SO-16G part number. It targets administrators who need verified error-correcting memory to protect data integrity in NAS or entry-level server workloads. The unbuffered design keeps latency low while maintaining compatibility with supported platforms. Major-brand chips and factory testing aim to deliver dependable operation.

Fits 260-pin DDR4 SO-DIMM slots at 1.2V

Installation requires a free 260-pin DDR4 SO-DIMM socket operating at 1.20V standard voltage. The module runs at PC4-17000 speed with CL15 timing and uses a 2Rx8 organisation. It frees the system from non-ECC limitations by adding single-bit error correction without needing registered buffering. Verify the motherboard or NAS firmware supports unbuffered ECC before fitting the module.

Replaces non-ECC or smaller DDR4 SODIMMs

This module upgrades systems currently running non-ECC DDR4 SO-DIMMs or lower-capacity ECC sticks where data protection is now required. The jump is worth it when workloads demand 16GB per slot with error correction for ZFS, virtualization or database caching. Buyers who need registered DIMMs, speeds above 2133MHz, or capacities beyond 16GB per slot should look elsewhere.
