32GB DDR4 2133 ECC LRDIMM Kit

This A-Tech kit provides 32GB of DDR4 2133 ECC LRDIMM server memory across two 16GB modules. It uses 288-pin Load Reduced DIMMs with 2Rx4 organisation and runs at 1.20V with CL15 latency. The kit is built for registered server and workstation platforms that require error-correcting, load-reduced memory.

Suited for servers needing ECC LRDIMM

This memory suits administrators upgrading compatible DDR4 servers or workstations that specifically accept 2Rx4 Load Reduced ECC DIMMs. It will not work in desktop or laptop computers, nor in systems that require standard Registered ECC RDIMMs, Unbuffered ECC UDIMMs, or non-ECC memory. Buyers needing higher speeds, different ranks, or larger single-module capacities must look elsewhere.

Verify DDR4 LRDIMM support and slots

Before ordering, confirm your motherboard or server manual lists support for DDR4 2133 ECC Load Reduced DIMMs in a 2Rx4 configuration. Check that two 288-pin DIMM slots are available in the correct channel arrangement for dual-channel operation. Ensure the platform voltage is 1.2V and that the BIOS can train CL15 timings at 2133 MHz.

Questions about this item

Does my server need DDR4 288-pin LRDIMM slots to use this 32GB kit?

Yes, the kit requires a server or workstation that accepts DDR4 288-pin ECC Load Reduced DIMMs; it will not fit desktop or laptop memory slots.

Can I mix these 2Rx4 PC4-17000 modules with existing DDR4 2133 registered DIMMs?

Mixing LRDIMMs with standard registered DIMMs is not supported; all slots must use the same Load Reduced technology for the system to operate correctly.

How do I confirm the kit is running at 2133 MHz with ECC active after installation?

Check the BIOS memory information or OS hardware report; it should show 32 GB total, 2133 MT/s speed, CL15 timing, 1.20 V and ECC enabled.
