128GB DDR5 RDIMM kit for SuperMicro servers

This 128GB kit delivers eight 16GB DDR5 4800 registered DIMMs built for SuperMicro X13SEI-F and X13SEI-TF motherboards. It targets administrators who need validated ECC memory for production workloads. Modules run at 1.1V with CL40 latency and use major OEM DRAM from Samsung, Micron or Hynix.

Eight 1Rx8 modules at 4800 MT/s with ECC

The kit populates eight slots with single-rank 1Rx8 RDIMMs rated at PC5-38400. Registered buffering and on-die ECC protect data integrity under sustained load. Capacity scales to 128GB across the supported platform; headroom ends when all DIMM sockets are filled or the board’s memory controller limit is reached.

Heat-spreader-free design simplifies dense

No heat spreaders are fitted, allowing tighter module spacing in 288-pin server boards. The package contains only the eight RDIMMs; no extra cables, software licences or mounting hardware are included. Installation follows the motherboard manual’s population rules for registered memory.

Questions about this item

Will this 8 x 16 GB DDR5 4800 CL40 kit run alongside my existing DDR5 RDIMMs on the same SuperMicro motherboard?

All eight modules are 1.1 V DDR5 4800 CL40 1Rx8 ECC RDIMMs; match speed, voltage, rank and ECC with any installed sticks and populate identical channels per the board manual for stable operation.

How can I verify the 128 GB kit is detected at 4800 MT/s with ECC active after installation?

Enter the BIOS or UEFI and confirm total memory shows 128 GB, data rate reads 4800 MT/s, and ECC status reports enabled or active for each populated slot.

Does the box include only the eight 16 GB RDIMMs or are there extra brackets or cables?

The package contains exactly the eight 16 GB DDR5 4800 CL40 1.1 V ECC RDIMMs; no brackets, cables or additional accessories are supplied.
