System-specific DDR5 server memory

This 128 GB kit contains four 32 GB DDR5 RDIMMs built for the SuperMicro X14SBW-F platform. Registered ECC modules with a 2Rx4 organisation provide the error correction and signal integrity that multi-socket server boards require. IT teams upgrading memory in validated SuperMicro systems receive a matched set tested for that platform.

Registered ECC with 2Rx4 organisation

The registered buffer and on-die ECC are the single specification that determines compatibility with the target motherboard. Unbuffered or non-ECC DIMMs will not function in this server design. Each module operates at the standard 1.10 V DDR5 voltage and carries a CL52 latency rating at the rated 6400 MT/s data rate.

Sustained load stability under AI workloads

Modules are stress-tested under continuous load to verify reliable operation during extended AI training and inference runs. The registered design reduces electrical loading on the memory controller, helping maintain signal quality when all fourteen ranks are populated. Samsung, Micron or Hynix DRAM components are selected for consistent thermal behaviour during prolonged high-utilisation periods.

Questions about this item

How does 6400 MT/s perform once the modules are installed in a SuperMicro X14SBW-F?

The kit runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.1 V, delivering the rated transfer rate on the supported server platform.

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

These are 288-pin DDR5 RDIMMs with registered buffering and ECC, matching the X14SBW-F memory slots and chipset requirements.

Will the four 32 GB sticks fit the X14SBW-F without a heat spreader?

Each module is a standard-height 288-pin RDIMM without a heat spreader, so all four occupy the board's DIMM slots normally.
