Exact-match server kit

This NEMIX RAM kit delivers 512 GB of DDR5 memory in four 128 GB Registered ECC RDIMMs. It is built for administrators upgrading a Supermicro X14SDW-42C-SP9F motherboard that requires the precise rank, voltage and timing the board expects.

Registered ECC stability

The Registered architecture buffers each command so all four slots can run fully populated at the rated 5600 MT/s speed. On-die ECC detects and corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots in production workloads.

4Rx4 organisation decides fit

Each module uses a 4Rx4 layout that the memory controller must support; boards limited to dual-rank or single-rank DIMMs will not recognise the full capacity. Verify the motherboard manual for approved population rules before ordering.

Questions about this item

Will the 128 GB modules need replacement as server workloads grow?

The 4Rx4 DDR5-5600 ECC RDIMM kit is validated for the Supermicro X14SDW-42C-SP9F motherboard, so the 512 GB capacity is recognised at full speed without further upgrades.

What limits sustained throughput first on these CL46 4Rx4 modules?

The registered architecture offloads the memory controller, allowing all four slots to run fully populated at DDR5-5600 with CL46 timing as the primary latency boundary.

How much heat and power do the 1.1 V DDR5 RDIMMs draw in continuous operation?

Each module operates at 1.10 V with no heat spreader; the registered design reduces electrical load on the controller, keeping thermals and power draw within standard DDR5 server limits.
