A-Tech 16GB DDR4 3200 ECC UDIMM 1Rx8 CL22 1.2V HMAA2GU7CJR8N-XN Server Memory

SKU CH-JK0X-TSFS3

16 GB DDR4 3200 ECC UDIMM with CL22 latency and 1.2 V operation for server and workstation upgrades

  • Capacity16GB
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredUnbuffered
  • 16GB ECC UDIMM adds reliable capacity for server workloads
  • DDR4 3200 speed accelerates data throughput in compatible systems
  • CL22 latency at 1.2V balances responsiveness with standard power draw

Capacity and Compatibility

This A-Tech 16GB DDR4 3200 ECC UDIMM serves as a compatible replacement for the Hynix HMAA2GU7CJR8N-XN module. It targets server and workstation systems that require error-correcting unbuffered memory at the standard 1.2V operating voltage. The single-rank 1Rx8 organisation uses major-brand components validated through quality-assurance testing.

Suitability and Limits

The module fits platforms that accept 288-pin DDR4 ECC UDIMMs running at PC4-25600 speeds with CL22 latency. It is not intended for systems that demand registered or load-reduced DIMMs, nor for boards limited to lower DDR4 data rates. Builders needing non-ECC memory or higher-density multi-rank modules should look elsewhere.

Deciding Specification

The critical match point is the ECC unbuffered UDIMM format combined with the exact 16GB 1Rx8 configuration at DDR4 3200 CL22. Verify that your motherboard or server documentation lists support for this specific rank structure and voltage before ordering.

Questions about this item

How much power does the 1.20V DDR4 3200 ECC UDIMM draw when the server runs continuously?

The module operates at the standard DDR4 voltage of 1.20V, keeping power draw low during all-day workloads.

What motherboard slot and memory controller features are required for this 288-pin ECC UDIMM to function?

A DDR4 UDIMM slot with ECC support in the memory controller is needed; registered or load-reduced DIMM slots will not accept this unbuffered module.

Will the CL22 1Rx8 16GB DDR4 3200 module run at its rated speed when installed beside slower DDR4 DIMMs?

The system will clock all installed DDR4 modules to the speed of the slowest DIMM, so this 3200 MT/s module will downshift to match slower memory.
