High-density server memory kit

This NEMIX RAM kit delivers 1 TB of DDR4 capacity across sixteen 64 GB modules. Each LRDIMM operates at 3200 MHz with a CAS latency of 22 and runs at 1.2 V. The load-reduced design and 4Rx4 organisation are built for registered ECC server platforms that accept 288-pin DDR4 memory.

Suited for dense virtualisation hosts

The kit targets administrators scaling memory in compatible DDR4 servers that support LRDIMM population rules. It is not for desktop PCs, workstations that require standard RDIMM or UDIMM modules, or any system that cannot address 4Rx4 load-reduced DIMMs. Buyers needing lower capacities or non-ECC memory should look elsewhere.

Straightforward module installation

Insert each 288-pin LRDIMM into the correct slots following the server vendor's population guide for 4Rx4 load-reduced memory. The most common issue is mixing LRDIMMs with RDIMMs or populating slots in an unsupported order, which prevents the system from posting. Verify BIOS revision and maximum per-socket capacity before installation.

Questions about this item

Does my server need 16 DDR4 288-pin LRDIMM slots to use this 1 TB kit?

Yes, the kit contains 16 modules of 64 GB each, so the motherboard must provide 16 DDR4 288-pin LRDIMM slots.

Can I mix these 4Rx4 ECC LRDIMM modules with existing 2Rx4 RDIMMs in the same server?

No, Load Reduced DIMMs and standard Registered DIMMs use different buffering and rank structures; they cannot be mixed in the same memory channels.

After installation, how can I confirm the kit is running at DDR4 3200 with CAS latency 22?

Check the BIOS or UEFI memory information screen — it should report 3200 MT/s speed and CL22 timings for all 16 modules.
