Exact-fit DDR5-5600 kit for Supermicro H13SSF

This NEMIX RAM kit delivers 768 GB across 16 modules of 48 GB each. Registered ECC DDR5-5600 RDIMMs run at 1.1 V with CL46 timing, matching the memory controller expectations of the Supermicro H13SSF motherboard. The 2Rx8 organization and 288-pin form factor ensure full-capacity recognition at rated speed. It is built for servers that require registered error-correcting memory in a validated population.

Registered ECC architecture for full-slot stability

Registered buffering offloads the memory controller so every slot can run fully populated at the rated 5600 MT/s. On-die ECC detects and corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots in production workloads. The kit uses major OEM DRAM from Samsung, Micron, or Hynix without heat spreaders, fitting standard DIMM clearance. Installers must follow the motherboard manual for approved population order and maximum supported capacity per channel.

Replaces smaller or slower DDR5 RDIMM sets

This kit upgrades systems currently running lower-capacity DDR5 registered modules or mixed-rank configurations that limit total memory or force reduced speeds. The jump is worth it when workloads demand the full 768 GB at DDR5-5600 without downclocking. It is not for platforms that accept only unbuffered UDIMMs, SODIMMs, or earlier DDR generations.

Questions about this item

What is the voltage and CAS latency that define the power and timing limits of these DDR5 5600 RDIMMs under sustained load?

The kit runs at 1.10V with a CL46 latency, the exact voltage and timing the memory controller expects for stable operation at full capacity.

How do the registered ECC design and 1.10V voltage affect heat and noise when all 16 slots are populated continuously?

Registered buffering reduces electrical load on the controller and the low 1.10V operation keeps power draw modest, so the modules add minimal heat and no audible noise of their own.

Which motherboard and form factor must already be installed for this 288-pin RDIMM kit to function?

A Supermicro H13SSF motherboard with 16 available 288-pin DDR5 RDIMM slots is required; the modules will not fit UDIMM or SODIMM sockets.
