128 GB DDR5 6400 ECC RDIMM kit

This NEMIX RAM kit delivers 128 GB of DDR5 memory across four 32 GB registered DIMMs. Each module runs at 6400 MT/s with a CAS latency of CL52 at 1.1 V. The 2Rx4 organization and on-die ECC are designed for the SuperMicro X14SBI-F platform.

Suited for servers needing maximum registered

The four-module population fills all slots on compatible SuperMicro boards, so administrators who need to leave DIMM slots open for future expansion should consider a smaller kit. Systems that require unbuffered UDIMMs or non-ECC memory cannot use these registered modules.

288-pin DDR5 RDIMM form factor

Installation requires a motherboard with DDR5 RDIMM slots and support for 2Rx4 registered modules at 6400 MT/s. Verify the platform memory qualification list before purchase to ensure the correct population rules and voltage are met.

Questions about this item

Will the four 288-pin DDR5 RDIMM modules fit the SuperMicro X14SBI-F memory slots?

Yes, the kit contains four 32 GB 288-pin DDR5 RDIMM modules designed for the SuperMicro X14SBI-F motherboard.

What is the correct installation sequence for the 2Rx4 registered DIMMs on this board?

Populate the slots in the order specified by the SuperMicro X14SBI-F manual, typically starting with the slot furthest from the CPU for each channel.

When should the 1.10 V registered ECC modules be replaced in a 24/7 server?

Replace modules if ECC correctable-error counts rise sharply or if the system logs uncorrectable memory errors during sustained load.
