Server memory kit

This NEMIX RAM kit provides 512GB of DDR4 server memory across two 256GB LRDIMM modules. It operates at 2933MHz with a CAS latency of 21 and a voltage of 1.2V. The load-reduced design reduces electrical load on the memory controller for high-density configurations.

Suited for compatible servers only

These modules are built for servers that support DDR4 2933MHz PC4-23400 8Rx4 ECC LRDIMM memory. They are not for desktop PCs or workstations that require standard UDIMM or RDIMM form factors. Buyers needing non-ECC memory or lower capacities should look elsewhere.

Sustained load behaviour

Under continuous operation the ECC function detects and corrects single-bit errors to maintain data integrity. The load-reduced architecture keeps signal integrity stable when both modules populate the 288-pin slots. The 1.2V rating supports consistent power draw during extended workloads.

Questions about this item

What server motherboard slot and voltage does this 288-pin DDR4 LRDIMM kit require?

The modules fit 288-pin DDR4 slots and run at 1.2V; the board must support DDR4 LRDIMM at 2933MHz.

Can I mix these 8Rx4 256GB LRDIMMs with standard RDIMMs already installed?

No — Load Reduced and Registered DIMMs cannot share a channel; all slots must use LRDIMM for this 512GB kit to operate.

How do I confirm the kit is running at 2933MHz with CL21 ECC after installation?

Check BIOS or OS memory info for 2933MT/s speed, CL21 timings, and ECC status showing active on both 256GB modules.
