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

SKU CH-0YEF-JH5ZP

16 GB DDR4 2666 MHz ECC RDIMM 1Rx4 server memory with 1.2 V operation and CL19 latency

  • Capacity16GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • ECC protection prevents data corruption in servers

  • DDR4 2666 MHz speed delivers PC4-21300 bandwidth
  • 2 V standard voltage reduces power consumption

Server Memory Upgrade

This 16 GB DDR4 2666 ECC RDIMM module targets administrators upgrading compatible servers or workstations. The registered design adds a buffer that stabilises the signal when multiple modules populate a channel. It replaces Micron MTA18ADF2G72PZ-2G6 and related part numbers in qualified systems.

DDR4 2666 Registered Limits

The DDR4 2666 interface caps throughput at the PC4-21300 data rate with CL19 latency at 1.20 V. Registered buffering introduces one clock cycle of latency but allows larger memory populations per channel than unbuffered DIMMs. System firmware must support ECC and registered modules for the DIMM to function.

16 GB Capacity Headroom

A single 1Rx4 16 GB rank suits moderate virtualization, database caching, or multi-user workloads that fit within the module count your platform allows. Workloads requiring more memory per channel will exhaust capacity once all supported slots are filled. Verify the maximum supported density and rank configuration before purchasing.

Questions sur cet article

Should I pick the 16 GB 1Rx4 ECC RDIMM or a different capacity for my server?

This module is a single 16 GB stick built with a 1Rx4 organisation. If your platform needs registered ECC memory and has free 288-pin slots, add one or more of these to reach the total capacity your workload requires.

What does the 2666 MHz PC4-21300 rating deliver inside a real machine?

The module runs at DDR4 2666 MT/s with a peak bandwidth of PC4-21300. At CL19 latency and 1.20 V it provides the throughput and error correction your server board expects from a registered DIMM.

How does the DDR4 288-pin RDIMM interface limit speed and capacity?

The 288-pin registered DIMM slot caps the module at DDR4 2666 and 16 GB per stick. Your system’s memory controller and qualified-vendor list determine the maximum number of ranks and total capacity you can populate.
