Server DDR4 ECC LRDIMM Kit

This A-Tech kit provides 64 GB of DDR4 2133 MHz ECC LRDIMM memory in two 32 GB modules. It uses a 288-pin DIMM form factor, quad-rank 4Rx4 organisation, and runs at 1.20 V. The modules are designed for server and workstation platforms that require load-reduced registered memory with error correction.

Platform Compatibility Check

Verify that your system supports DDR4 ECC LRDIMM modules with a 4Rx4 rank configuration and 288-pin DIMM slots. Consult the motherboard or server manual for qualified memory lists, maximum capacity per slot, and required population rules for multi-channel operation. This kit is not compatible with standard desktop or laptop computers.

Capacity and Rank Upgrade

The kit replaces lower-capacity or single-rank DDR4 LRDIMM modules to increase total memory bandwidth and allow larger datasets in memory. The jump is worthwhile when workloads exceed current RAM limits or when the platform can populate all channels with quad-rank modules for maximum throughput.

Questions about this item

What is included in the 64GB kit and do I need to buy anything else?

The kit contains two 32GB DDR4 2133 ECC LRDIMM modules. No extra parts are required if your server or workstation supports DDR4 ECC Load Reduced memory.

How do I decide between this 4Rx4 kit and other capacities or ranks?

Choose this 64GB 4Rx4 kit when your system needs quad-rank Load Reduced DIMMs at 2133 MHz. Match the rank, voltage and ECC type to your platform's qualified vendor list.

What does the 2133 MHz rating mean once the memory is installed in a server?

The modules run at DDR4 2133 with CL15 latency at 1.2V, delivering PC4-17000 bandwidth per channel when the memory controller is configured for that speed.
