Exact-match server upgrade

This NEMIX RAM kit delivers 256 GB of DDR5 memory in two 128 GB Registered ECC RDIMMs built for the Supermicro X14SDW-36CE-SP9F motherboard. The modules operate at 5600 MT/s with CL46 latency at 1.1 V and use a 4Rx4 organisation that matches the board's memory controller expectations.

288-pin Registered ECC form factor

The DDR5 RDIMM format with 288 pins and registered buffering is the single specification that determines fitment; the board requires this exact physical and electrical interface and will not accept UDIMM or SODIMM alternatives.

Full-population capacity headroom

Two dual-rank modules fill both DIMM slots at the rated 5600 MT/s speed, providing 256 GB of error-correcting memory for virtualisation and database workloads. Adding further capacity would require a motherboard with additional memory channels or higher-density DIMMs not supported by this platform.

Questions about this item

How does the 5600 MT/s speed translate when the kit is installed in the Supermicro X14SDW-36CE-SP9F?

The modules run at DDR5-5600 (PC5-44800) with CL46 timing at 1.1 V, delivering the full rated throughput the board's memory controller expects when all slots are populated.

What does the 288-pin RDIMM interface cap in practice?

The 288-pin registered DDR5 form factor supports ECC and registered signalling, allowing every slot to operate at the full 256 GB capacity without the electrical loading limits of unbuffered modules.

What physical clearance does the 2 x 128 GB kit need to fit the motherboard?

Each 288-pin RDIMM uses the standard DDR5 height with no heat spreader, so it fits the Supermicro X14SDW-36CE-SP9F DIMM slots following the board's documented population order.
