Exact-fit 64GB DDR5-5600 ECC RDIMM kit

This NEMIX RAM kit delivers 64GB as two 32GB DDR5-5600 registered ECC modules built for the Supermicro X14SDV-36C-SP3F motherboard. Each 288-pin RDIMM runs at 1.1V with CL46 timing and 2Rx8 organisation so the memory controller recognises the full capacity at rated speed.

DDR5-5600 registered ECC bandwidth ceiling

The PC5-44800 interface caps usable throughput at the DDR5-5600 data rate while registered buffering and ECC add latency overhead versus unbuffered non-ECC alternatives. Full-slot population on this platform is limited by the board's own memory-population rules rather than the modules themselves.

Verify Supermicro X14SDV-36C-SP3F DIMM rules

Confirm the motherboard manual for approved capacity per slot, required population order and any BIOS version needed before installing this 2Rx8 registered kit. Systems needing unbuffered UDIMMs, SODIMMs, or a different voltage cannot use these modules.

Questions about this item

Should I choose the 64GB kit or buy single 32GB modules for my Supermicro X14SDV-36C-SP3F?

The 64GB kit contains two matched 32GB modules (2Rx8) tested together for dual-channel operation. Buying singles risks timing mismatches that can prevent the board from running at the rated DDR5-5600 speed.

What does the DDR5-5600 (PC5-44800) rating deliver once installed in this Supermicro board?

The modules run at 5600 MT/s with CL46 latency at 1.1V, giving the maximum bandwidth the X14SDV-36C-SP3F memory controller supports when both slots are populated with registered ECC DIMMs.

How does the 288-pin RDIMM interface and registered ECC design affect real-world capacity limits?

The registered buffer lets the memory controller drive both 2Rx8 modules at full 5600 MT/s without signal degradation, while ECC corrects single-bit errors on the fly — essential for the 64GB capacity this board validates.
