A-Tech 32GB DDR4 2666MHz ECC Registered RDIMM 2Rx4 288-Pin Server Memory

SKU CH-9R0E-YGBA9

32 GB DDR4 2666 MHz ECC registered RDIMM, dual-rank 2Rx4, 1.2 V, Supermicro certified with Micron chips

  • Capacity32GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • ECC registered design protects data integrity in critical workloads
  • 32 GB capacity expands server memory for demanding applications
  • DDR4 2666 MHz speed delivers PC4-21300 bandwidth for responsive performance
  • Supermicro certified module ensures validated compatibility with qualified platforms
  • 2 V standard voltage maintains efficient power consumption across 288-pin RDIMM form factor

Server Memory for Enterprise Workloads

This 32GB DDR4 RDIMM targets servers and workstations that require error-correcting registered memory. It fits systems validated for the Supermicro MEM-DR432L-CL05-ER26 part number and Micron chipset. Builders needing unbuffered DIMMs or non-ECC modules cannot use this product.

Capacity and Speed Headroom

A single module delivers 32GB at 2666MHz with CL19 latency and 1.20V operation. The dual-rank 2Rx4 organisation helps populate high-density configurations. Workloads exceeding 32GB per slot or requiring speeds beyond PC4-21300 will need additional modules or a faster platform.

Build Quality and Daily Implications

Registered buffering and ECC protect data integrity in multi-module arrays. The 288-pin RDIMM form factor locks into standard server DIMM sockets. Each unit undergoes validation testing before shipment. Systems without registered ECC support will not POST with this module installed.

Perguntas sobre este artigo

Will this 2666 MHz DDR4 RDIMM run at its rated speed when installed alongside slower DDR4 modules already in my server?

The module is rated for DDR4 2666 (PC4-21300) at CL19; when mixed with slower DDR4 DIMMs the memory controller will downclock all modules to the lowest common speed.

How can I confirm the ECC registered function is active after installing the 32 GB module?

Check the BIOS or operating system memory report — it should show 32 GB detected, ECC enabled, and registered (RDIMM) status at 2666 MHz with CL19 timings.

Does the single 32 GB 2Rx4 RDIMM ship with any brackets, cables or a heat-spreader, or must those be purchased separately?

The box contains only the 288-pin DDR4 RDIMM module; no brackets, cables or additional heat-spreader are included or required for standard server DIMM slots.
