128GB DDR5 ECC RDIMM kit for SuperMicro X13SEI-F/TF

This 128GB kit (2x64GB) of DDR5 4800 CL40 ECC registered DIMMs is built for SuperMicro X13SEI-F and X13SEI-TF motherboards. It targets administrators and integrators who need maximum supported capacity on these specific server platforms.

288-pin registered modules at 1.1V with Samsung.

Each 64GB module uses a 2Rx4 organisation and runs at 1.10V without a heat spreader. The registered buffer and ECC function reduce electrical load on the memory controller and correct single-bit errors, which is essential for 24/7 server workloads on the named boards.

Replaces lower-capacity

The jump is worth it when the workload demands the full 128GB registered capacity with error correction. It is not for desktop boards that cannot address registered ECC modules, nor for platforms requiring a different DDR generation or pin count.

Questions about this item

Does the DDR5 4800 interface cap bandwidth at PC5-38400 speeds?

Yes, the kit runs at DDR5 4800 which corresponds to the PC5-38400 bandwidth ceiling.

What motherboard slot and pin count do these 288-pin RDIMMs need to fit?

They require a standard 288-pin DDR5 DIMM slot on a SuperMicro X13SEI-F or X13SEI-TF board.

How are the two 64 GB modules installed, and what sequencing step is often missed?

Insert both modules into the matching channel slots indicated in the server manual, locking each ejector until it clicks.
