128GB DDR5 4800 ECC RDIMM Kit

This 128GB kit contains eight 16GB DDR5 4800 registered DIMMs with ECC. It operates at 1.1V with CL40 latency and uses a 288-pin form factor. The modules are 1Rx8 rank and built with major OEM chips from Samsung, Micron or Hynix.

Suited for SuperMicro X13SEM servers.

These modules suit SuperMicro SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-TF systems that require registered ECC memory. Builders using consumer motherboards or workstations without registered DIMM support should look elsewhere.

Registered ECC with 1Rx8 organisation

The single specification that decides fit is the registered ECC RDIMM design with 1Rx8 organisation. Only systems that explicitly accept this module type will POST and run stably with this kit.

Questions about this item

What comes in the box and is anything else required for installation?

The kit contains eight 16 GB DDR5 4800 ECC RDIMM modules totalling 128 GB; no extra parts are needed to install them in a compatible SuperMicro system.

Which version or capacity should I choose for my SuperMicro server?

This 128 GB kit with eight 16 GB 1Rx8 registered DIMMs matches the specifications for the SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-TF platforms.

What does the CL40 latency mean when the memory is running in my server?

CL40 is the CAS latency at the native DDR5 4800 speed, so the modules operate at their rated timing without downclocking in supported SuperMicro systems.
