Four green DDR5 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 256GB 4x64GB DDR5 6400 CL52 4Rx4 1.1V ECC RDIMM Supermicro X14SDV-32C-SP3F memory upgrade

SKU CH-38XH-R8SYF

256GB DDR5-6400 ECC RDIMM kit in four 64GB 4Rx4 modules at 1.1V CL52, validated for the Supermicro X14SDV-32C-SP3F motherboard

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

Size 256GB 4X64GB

  • 256 GB total capacity from four 64 GB modules
  • DDR5 6400 speed with CL52 latency for rated throughput
  • 1 V registered ECC design protects data integrity
  • 4Rx4 organisation enables full population on supported boards
  • 288-pin RDIMM form factor matches Supermicro X14SDV-32C-SP3F requirements

Exact-fit DDR5 ECC RDIMM kit

This 256GB kit contains four 64GB DDR5-6400 registered ECC modules built for the Supermicro X14SDV-32C-SP3F motherboard. Each DIMM runs at 1.1V with CL52 latency and a 4Rx4 organisation. The registered design lets the board run fully populated without overloading the memory controller.

4Rx4 registered ECC at 6400 MT/s

The single specification that decides fitment is the 4Rx4 registered ECC profile at DDR5-6400 (PC5-51200). Your motherboard must accept 288-pin RDIMMs with exactly that rank, voltage and timing; a UDIMM, SODIMM or different rank count will not be recognised. Verify the manual’s approved population table before ordering.

Tool-free press-in install

Align the notch on each 288-pin module with the slot key, press straight down until both latches click, and repeat for all four slots in the order the manual specifies. The most common issue is mixing ranks or skipping a required slot sequence, which leaves capacity unrecognised or forces the system to run at a lower speed.

Questions sur cet article

What does the 6400 MT/s rating mean once the modules are installed in a Supermicro X14SDV-32C-SP3F?

The kit runs at DDR5-6400 (PC5-51200) with CL52 latency at 1.1 V, so the memory controller recognises all 256 GB at the rated speed without down-clocking.

How does the 288-pin RDIMM interface and registered design affect what the motherboard can use?

The board requires 288-pin registered DIMMs; the buffered architecture lets every slot stay fully populated at 64 GB per module while ECC corrects single-bit errors on the fly.

What physical clearance or slot population rules apply when fitting the four 64 GB sticks?

Each module is a standard-height 288-pin RDIMM with no heat spreader; follow the X14SDV-32C-SP3F manual for the approved DIMM population order before installing all four.
