Server memory kit

This A-Tech kit supplies 128GB of DDR4 ECC registered memory across eight 16GB modules running at 2666 MHz with CL19 latency. It is built for servers and workstations that require registered DIMMs and error-correcting code for data integrity.

Registered DIMM requirement

The modules suit administrators upgrading compatible DDR4 server or workstation platforms that accept 1Rx4 registered memory. They will not work in desktop or laptop computers that use unbuffered non-ECC DIMMs.

288-pin installation

Each 288-pin DIMM seats in a standard DDR4 registered slot; follow the system manual for correct channel population and seating order. The most common issue is installing these registered modules in a consumer board that only supports unbuffered memory.

商品問答

What type of system must I already have for this 288-pin DDR4 2666 ECC RDIMM kit to work?

You need a server or workstation that supports DDR4 registered ECC memory; desktop and laptop platforms will not accept these modules.

Can I keep my existing DDR4 2666 registered ECC DIMMs and add this 1Rx4 kit alongside them?

Yes, provided your platform accepts mixed ranks and the total capacity stays within the motherboard and CPU limits; all modules will run at the lowest common speed and voltage.

How can I confirm the kit is running at the rated 2666 MT/s with CL19 latency after installation?

Check the memory speed and timings in the system BIOS or UEFI, or use a hardware information utility inside the operating system to verify DDR4 2666 and CL19 values.
