  • 256 GB capacity from two 128 GB modules expands server memory headroom
  • DDR5 6400 speed with CL52 latency delivers rated throughput for demanding workloads
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 10 V operation at 4Rx4 rank matches the memory controller's exact requirements
  • 288-pin RDIMM form factor fits Supermicro X14SRG-TF motherboard slots precisely

Exact-match kit for Supermicro X14SRG-TF

This 256 GB DDR5 kit contains two 128 GB registered ECC RDIMMs built to the board's precise rank, voltage and timing requirements. It is intended for administrators upgrading that specific Supermicro motherboard with memory the controller will recognise at full capacity and rated speed.

Registered 4Rx4 ECC at 1.1 V

The modules run at DDR5 6400 (PC5-51200) with CL52 latency and a 1.10 V operating voltage. Registered architecture and 4Rx4 organisation let the memory controller drive every slot fully populated while on-die ECC corrects single-bit errors before they affect production workloads.

256 GB headroom for dense virtualisation

Two 128 GB DIMMs fill two slots and deliver the maximum capacity this kit provides, supporting large VM counts and in-memory databases. Builders needing more than 256 GB or a different form factor such as UDIMM or SODIMM must look elsewhere.

Questions about this item

What does the 6400 MT/s speed mean once this kit is installed in a Supermicro X14SRG-TF?

The modules run at DDR5-6400 (PC5-51200) with CL52 latency at 1.1 V, delivering the exact data rate the motherboard's memory controller expects for full-capacity operation.

How does the 288-pin RDIMM interface limit or enable use on this board?

The 288-pin Registered DIMM form factor is required by the X14SRG-TF; it will not accept UDIMM or SODIMM modules, and the registered design allows every slot to be populated at 128 GB per DIMM.

What physical clearance and slot layout does this 2 x 128 GB kit need?

Each 288-pin RDIMM fits a standard DDR5 server DIMM slot with no heat spreader, so verify the motherboard's population order in the manual before installing both modules.
