Capacity and fit

This NEMIX RAM module provides 32GB of DDR5 memory in a single 288-pin ECC RDIMM. It is built for the SuperMicro X14SBI-F platform and runs at 6400MT/s with CL52 latency at 1.1V. The 2Rx4 organization and registered buffer suit server and workstation workloads. No heat spreader is fitted.

Who this suits and who it does not

This kit suits administrators upgrading a SuperMicro X14SBI-F system that requires registered ECC DDR5 at 6400MT/s. It does not suit builders needing unbuffered UDIMMs, non-ECC memory, or a different pin count. Buyers who want a heat spreader or a multi-module kit should look at other options.

Deciding specification

The registered ECC RDIMM form factor with 2Rx4 organization is the single specification that decides compatibility. Only systems that accept registered DDR5 ECC modules at this speed and voltage will support this part.

Questions about this item

How does the 6400 MT/s speed translate once the module is installed in a SuperMicro X14SBI-F?

The module runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.10 V, delivering the rated throughput when the platform enables that data rate.

What does the 288-pin RDIMM form factor and registered ECC design mean for compatibility?

It fits a standard DDR5 288-pin RDIMM slot; the registered buffer and on-die ECC require a server chipset that supports registered ECC memory.

Will the 32 GB 2Rx4 stick fit the DIMM slots on the X14SBI-F without clearance issues?

The module is a standard-height 288-pin DDR5 RDIMM with no heat spreader, so it occupies a single DIMM slot and clears typical server heatsinks.
