128GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers 128GB of DDR5 registered ECC memory across four 32GB modules. It operates at 4800MHz with CL40 latency at 1.10V. The 2Rx8 288-pin RDIMM form factor is built for the Supermicro H13DSG-O-CPU motherboard.

For Supermicro H13DSG-O-CPU servers

Suits administrators upgrading that specific Supermicro platform with a validated, fully populated memory configuration. Not for systems that require UDIMM or SODIMM modules, nor for boards that do not support registered ECC DDR5 at this speed and rank.

Kit of four matched modules

The package contains four 32GB RDIMMs pre-configured as a 128GB set. This eliminates the need to source individual sticks and ensures consistent rank, voltage, and timing across all populated slots for stable operation.

Questions about this item

Do I need a Supermicro H13DSG-O-CPU motherboard with 288-pin DDR5 RDIMM slots to use this 128GB kit?

Yes, this 4x32GB DDR5 4800MHz ECC Registered RDIMM kit is built for the Supermicro H13DSG-O-CPU motherboard and requires its 288-pin registered DIMM slots.

Will these 2Rx8 CL40 modules run at DDR5 4800 if I populate all four slots alongside any existing RDIMMs?

The kit is spec-matched to the board's memory-population rules; mixing ranks or speeds can downclock the bus, so the manual should be checked for approved DIMM order before adding other modules.

How can I confirm the 128GB kit is running at PC5-38400 with ECC active after installation?

Enter the BIOS or use a tool like dmidecode to verify each 32GB module shows DDR5 4800, CL40, 1.1V, 2Rx8 registered and that ECC is reported as enabled.
