  • 2Rx4 organisation using major OEM Samsung, Micron, Hynix chips
  • Verified fit for Supermicro X14SDV-36CE-SP3F motherboard

Exact-match DDR5 server kit

This 128 GB kit delivers two 64 GB DDR5 5600 RDIMM modules built to the Supermicro X14SDV-36CE-SP3F motherboard's precise rank, voltage and timing requirements. Registered ECC architecture with CL46 latency at 1.1 V ensures the memory controller recognises full capacity at rated speed.

Replaces mismatched or smaller DIMMs

The 2Rx4 registered design offloads the controller so every slot runs fully populated without down-clocking, while on-die ECC corrects single-bit errors before they cause silent data corruption. Upgrading is worth it when your current configuration limits total capacity or forces mixed-rank populations that reduce stability.

Fits 288-pin RDIMM slots only

Modules require a motherboard wired for DDR5 registered memory and will not work in UDIMM or SODIMM sockets. Populating both channels with this matched pair frees remaining slots for future expansion while keeping the memory subsystem at its validated 5600 MT/s operating point.

Questions about this item

Does the 288-pin RDIMM form factor fit the Supermicro X14SDV-36CE-SP3F motherboard slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the board requires — not UDIMM or SODIMM — so each module seats directly in the server's DIMM slots.

What is the correct population order when installing the two 64 GB modules?

Consult the Supermicro X14SDV-36CE-SP3F manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first for full 128 GB recognition.

Will the ECC and registered architecture need any firmware updates or battery-backed maintenance over time?

ECC error correction and registered buffering operate in hardware; no firmware updates or battery maintenance are required for the memory modules themselves.
