High-capacity DDR4 LRDIMM kit

This NEMIX RAM kit delivers 512 GB of DDR4 memory across four 128 GB LRDIMMs. Each module runs at 3200 MT/s with a CAS latency of 22 at 1.2 V. The load-reduced design lowers electrical load on the server memory bus.

Suited for dense server deployments

The 4Rx4 organisation and ECC support target multi-socket platforms that need maximum capacity per channel. Workstations or desktop boards that accept only standard UDIMMs or RDIMMs cannot use these modules.

Steady throughput under load

LRDIMM buffering keeps signal integrity stable when all ranks are active during sustained workloads. The 1.2 V operating voltage helps maintain consistent power draw across long compute runs.

Questions about this item

What server platform is required to run the DDR4 3200 PC4-25600 ECC LRDIMM modules?

The modules require a server motherboard with DDR4 DIMM slots that support 288-pin ECC Load Reduced DIMMs at 1.2V and can address 4Rx4 density.

Can the 4Rx4 LRDIMM kit operate alongside existing RDIMM modules in the same server?

LRDIMMs and standard RDIMMs use different buffering architectures; mixing them in the same channel is not supported by server platforms.

How do I verify the 512 GB kit is detected at 3200 MHz with CAS 22 after installation?

Enter the server BIOS or UEFI and confirm all four 128 GB modules show 3200 MT/s, CL22, 1.2 V and ECC enabled.
