Server Memory Kit

This 384GB kit contains six 64GB DDR5 4800 RDIMM modules rated at CL40 and 1.1V. It is built with ECC and registered buffering for data integrity in multi-socket server boards. The 288-pin form factor matches the DDR5 RDIMM slot standard used in compatible Supermicro platforms.

Supermicro Platform Fit

The kit is validated for the SuperMicro X13SEI-F and X13SEI-TF motherboards, making it a direct upgrade path for administrators expanding memory on those specific server models. Builders using different motherboards or non-ECC consumer platforms should verify qualification before purchasing.

Capacity per Module

Each module provides 64GB in a dual-rank 2Rx4 organisation, so the total 384GB is only reached when all six DIMMs populate the available channels. Systems with fewer than six slots cannot use the full kit as supplied.

Questions about this item

Should I pick the 6 x 64 GB kit or a different capacity for my SuperMicro X13SEI-F?

This kit provides 384 GB total across six 64 GB modules, matching the board's six-channel DDR5 architecture.

What does DDR5 4800 actually deliver once the modules are installed?

The rated 4800 MT/s speed runs at 1.1 V with CL40 latency, giving the maximum JEDEC-standard throughput this platform supports.

How does the 288-pin RDIMM interface limit what I can do with these modules?

The 288-pin registered DIMM form factor with ECC and 2Rx4 organisation fits only server boards wired for DDR5 RDIMMs, not desktop UDIMM slots.
