1.1TB DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 1.1TB of DDR5 4800MHz registered ECC memory across twelve 96GB modules. It uses a 2Rx4 organisation and runs at 1.1V on standard 288-pin RDIMM slots. The modules are built with major OEM DRAM from Samsung, Micron or Hynix.

Suited for high-density DDR5 servers

The kit targets servers and workstations that require registered ECC DDR5 at 4800MHz with a 2Rx4 rank structure. It is not for desktop PCs, laptops or any system that accepts only unbuffered non-ECC memory. Buyers needing lower capacities, different speeds or unregistered DIMMs should look elsewhere.

Straightforward RDIMM installation

Installation follows standard 288-pin RDIMM procedures: align the notch, press firmly until the latches click, and populate slots per the motherboard manual for optimal channel balance. The most common issue is mixing registered ECC with unbuffered memory or exceeding the platform's supported rank count per channel.

Questions about this item

What motherboard slot and memory type are required to install these 288-PIN DDR5 RDIMMs?

A server motherboard with DDR5 RDIMM slots that accept 288-pin registered modules is required.

Can I mix these 4800MHz 2Rx4 modules with slower DDR5 RDIMMs already in my server?

The system will run all modules at the speed of the slowest installed kit, so slower DDR5 RDIMMs will reduce overall bandwidth.

How can I verify the 12 modules are running at 4800MHz with CAS latency 40 after installation?

Check the memory speed and timing in the server BIOS or use a hardware information tool inside the operating system.
