A-Tech 16GB DDR4 2666 ECC RDIMM 1Rx4 1.2V Server Memory

SKU CH-ZKPQ-9AEXE

16 GB DDR4 2666 ECC registered DIMM with CL19 latency and 1.2 V operation

  • Capacity16GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 16 GB DDR4 2666 MHz boosts server responsiveness
  • ECC RDIMM with registered design protects data integrity
  • 1Rx4 single-rank layout supports dense memory configurations
  • 2 V DDR4 standard voltage reduces power draw
  • 288-pin DIMM form factor fits standard server slots

What This Module Is

This is a 16GB DDR4 2666 ECC Registered DIMM built as a compatible replacement for specific Micron server parts. It runs at 1.2V with CL19 latency and a 1Rx4 organisation on a 288-pin form factor. The module targets administrators upgrading or repairing enterprise platforms that require registered error-correcting memory.

Who This Suits

Suits technicians replacing a failed Micron MTA18ADF2G72PZ-2G6D1 or equivalent module in a validated server chassis. Not suited for desktop boards that accept only unbuffered non-ECC DIMMs, nor for systems needing higher density ranks or faster data rates than 2666 MT/s.

Deciding Specification

The registered ECC design with 1Rx4 layout is the single attribute that determines fit. Only platforms qualified for registered DDR4 2666 at 1.2V will recognise and stabilise this module.

Perguntas sobre este artigo

Will the 288-pin DDR4 RDIMM fit the DIMM slots on my server motherboard?

Yes, the module uses the standard 288-pin DDR4 RDIMM form factor that matches server DIMM slots designed for registered memory.

Can I add this 1Rx4 CL19 module alongside existing 2Rx8 DDR4 2666 RDIMMs in the same channel?

Mixing 1Rx4 and 2Rx8 ranks in one channel is not recommended; the memory controller may downclock or disable ECC, so use identical rank configurations per channel.

How do I confirm the 16 GB module is running at 2666 MHz with ECC active after installation?

Enter the BIOS or run a tool like dmidecode; it should report 2666 MT/s, PC4-21300, registered ECC, 1.20 V and 16 GB per DIMM.
