Four green DDR5 RDIMM modules without heat spreaders in a 256GB kit

NEMIX RAM

NEMIX RAM DDR5 6400 256GB 4x64GB CL52 1.1V 4Rx4 ECC Registered RDIMM memory upgrade

SKU CH-F37T-GNFG2

256 GB DDR5 registered ECC server memory kit, four 64 GB modules at 6400 MHz CL52 1.1 V, validated for Supermicro X14SDI-36C-SP3F

  • Capacity256GB (4 x 64GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 256GB 4X64GB

  • 256 GB total capacity lets you fully populate four slots with 64 GB modules
  • DDR5 6400 speed with CL52 latency matches the motherboard's rated timing for stable operation
  • Registered ECC architecture offloads the controller and corrects single-bit errors to prevent data corruption
  • 1 V operating voltage meets the board's spec for efficient server memory performance
  • Verified compatible with the Supermicro X14SDI-36C-SP3F motherboard for exact-fit installation

Targeted Server Upgrade

This 256GB kit delivers four 64GB DDR5 6400 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro X14SDI-36C-SP3F memory controller expects. The 4Rx4 organisation and 1.1V operation let every slot run fully populated at rated speed without manual tuning.

Replaces Lower-Capacity Kits

Swapping a smaller or slower DDR5 kit for this 4x64GB set adds the full 256GB the board can address in a single validated configuration, eliminating the guesswork of mixing modules. The jump is worthwhile when workloads need the maximum registered capacity this platform supports.

DDR5 RDIMM Constraints

Registered DDR5 modules require a motherboard wired for 288-pin RDIMM signalling and a BIOS that recognises 4Rx4 density at PC5-51200 speeds. Systems limited to UDIMM, SODIMM or lower rank counts will not post with this kit installed.

Questions about this item

Will these 288-pin DDR5 RDIMMs physically fit the Supermicro X14SDI-36C-SP3F motherboard slots?

Yes, the kit uses the 288-pin RDIMM form factor that the X14SDI-36C-SP3F requires; it is not a UDIMM or SODIMM.

What is the correct installation order for the four 64 GB modules on this board?

Consult the Supermicro X14SDI-36C-SP3F manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first.

Do the modules need any firmware updates or thermal-pad replacement during their service life?

No firmware updates or thermal-pad changes are required; the registered ECC design runs at 1.1 V without a heat spreader and is covered by a lifetime replacement warranty.
