A-Tech 64GB DDR4 2666 ECC RDIMM kit

This A-Tech kit provides 64 GB of DDR4 server memory in two 32 GB registered DIMMs. Each module runs at 2666 MHz with CL19 latency and 1.2 V operation. The dual-rank x4 layout and ECC registration suit enterprise workloads that demand data integrity and sustained throughput.

Verify DDR4 RDIMM support before ordering

Confirm that your server or workstation accepts DDR4 registered ECC DIMMs on a 288-pin interface. Desktop and laptop platforms cannot use these modules. Check the system manual for qualified memory lists, maximum capacity per slot, and required population order for dual-channel operation.

Suits IT teams expanding compatible servers

Organisations adding capacity to validated DDR4 RDIMM platforms will benefit from the matched pair and lifetime warranty. Buyers needing unbuffered UDIMMs, higher frequencies, or memory for consumer desktops should select a different product class.

Questions about this item

Does the kit include two 32 GB modules or do I need to buy them separately?

The kit contains two 32 GB modules for a total of 64 GB. No additional modules are required.

Should I choose the 2Rx4 dual-rank x4 version or a different rank option?

This kit is the 2Rx4 dual-rank x4 configuration. Select it if your server or workstation specifies DDR4 2666 registered ECC memory with dual-rank x4 organisation.

Will the advertised 2666 MHz speed run at that frequency once installed in my server?

The modules are rated for DDR4 2666 (PC4-21300) at CL19 and 1.20 V. The actual operating speed depends on your platform's memory controller and BIOS settings.
