Green 288-pin DDR4 LRDIMM module with black memory chips

A-Tech

A-Tech 64GB DDR4 2933 ECC LRDIMM 4Rx4 288-Pin 1.2V CL21 Server RAM

SKU CH-XN9A-8219H

A 64 GB DDR4 2933 ECC load-reduced DIMM with quad-rank x4 organisation, CL21 timing and 1.2 V operation for server and workstation memory expansion

  • Total capacity64 GB
  • Rated speedDDR4 2933 (PC4 23400)
  • ChipsetMajor Brand Chipset
  • CAS latencyCL21
  • Rated voltage1.2 V
  • Buffer typeLoad Reduced

Capacity 64GB

  • 64 GB capacity handles larger workloads and more virtual machines
  • DDR4 2933 MHz speed accelerates data throughput for demanding applications
  • ECC Load Reduced DIMM corrects errors and reduces electrical load on the memory bus
  • Quad Rank x4 organisation maximises density within a single 288-pin module
  • 2 V standard voltage lowers power draw while maintaining server stability

Target Platform

This 64 GB DDR4 module is built for servers and workstations that require ECC load-reduced memory. It will not function in desktop or laptop systems. Buyers who need standard unbuffered DIMMs or non-ECC memory for consumer platforms cannot use this product.

Installation Notes

The 288-pin DIMM seats like any DDR4 module, but the quad-rank 4Rx4 organisation means each slot presents a heavier electrical load. Systems with strict rank-per-channel limits may not accept a full complement of these modules. Always consult the platform manual for population rules and channel guidelines before installing.

Capacity and Headroom

A single 64 GB stick running at 2933 MHz with CL21 latency at 1.2 V provides substantial memory headroom for virtualisation, large databases and compute-intensive workloads. Workloads that exceed the module count supported by the memory controller will require a platform with more channels or higher-density modules.

Questions about this item

How can I verify the module is running at 2933 MHz and CL21 after installation?

Enter the server BIOS or use a hardware monitoring tool; the memory should report DDR4-2933 speed and CAS latency 21 at 1.20 V.

What comes with the 64 GB module and is anything else required?

The box contains one 288-pin LRDIMM; no extra parts are needed if your server supports DDR4 ECC load-reduced memory.

Should I choose the 4Rx4 version or a different rank for my server?

Select this 4Rx4 module only when your system's qualified-vendor list specifies quad-rank x4 LRDIMMs; other ranks will not be compatible.
