768GB DDR5 ECC RDIMM Kit for SuperMicro X13SEI

This 768GB kit contains six 128GB DDR5 4800 CL40 registered ECC modules built for SuperMicro X13SEI-F and X13SEI-TF motherboards. It targets IT professionals running memory-intensive server workloads that require error correction and registered signalling.

Verify six free DDR5 RDIMM slots and CPU support

Confirm the motherboard has six available 288-pin DDR5 RDIMM slots and that the installed processors support 4Rx4 registered modules at 4800 MT/s. The kit operates at 1.1V with CL40 latency and requires a platform qualified for PC5-38400 registered memory.

Replaces smaller-capacity DDR5 RDIMM kits

The jump is worthwhile when moving from lower-density kits that leave slots empty or force mixed-rank populations. Six matched 128GB modules fill the board in a single validated configuration for maximum capacity.
