384GB DDR4 ECC LRDIMM Kit

This 384GB kit contains six 64GB DDR4 2666 LRDIMM modules rated at CL19 and 1.20V. It is built for servers and workstations that require very high memory capacity with error correction and load-reduced signalling.

Check Motherboard LRDIMM Support

Verify that your server board accepts DDR4 LRDIMM modules at 2666 MT/s and can populate six slots with 4Rx4 ranks. The platform must also support ECC operation and supply 1.20V to the 288-pin slots.

Replaces Smaller RDIMM or Non-ECC Kits

The jump is worthwhile when workloads exceed the capacity of standard RDIMM configurations or when data integrity demands ECC. It is not suited for consumer desktops that lack LRDIMM support or for builds needing only modest memory amounts.
