128GB DDR5 ECC RDIMM Kit for Supermicro H14SST-G

This 128GB kit contains two 64GB DDR5 5600 (PC5-44800) Registered ECC RDIMMs built for the Supermicro H14SST-G motherboard. The modules run at 1.1V with CL46 latency and a 2Rx4 organisation, matching the board's memory controller expectations for full-capacity recognition at rated speed. It is intended for server administrators who need to maximise the memory capacity of this specific platform.

Verify Motherboard Population Rules Before Ordering

The Supermicro H14SST-G has defined DIMM population rules and maximum supported capacities per slot that must be followed for stable operation. Consult the motherboard manual to confirm the approved installation order and any capacity limits per channel before installing this 2Rx4 Registered kit. Installing modules in an unsupported sequence can prevent the system from booting or reduce available memory.

Registered ECC Architecture for Fully Populated

The Registered (buffered) design reduces electrical load on the memory controller, allowing all populated slots to run at the rated 5600 speed when fully populated. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads. The 288-pin RDIMM form factor fits only DDR5 RDIMM slots; it is not compatible with UDIMM or SODIMM sockets.

Questions about this item

What comes in the 128GB kit and do I need anything else to install it in a Supermicro H14SST-G?

The kit includes two 64GB DDR5 5600 CL46 2Rx4 1.1V 288-pin ECC registered RDIMMs; no extra parts are required for installation in the Supermicro H14SST-G motherboard.

Should I choose this 2x64GB 5600 CL46 kit or a different capacity for my Supermicro H14SST-G?

This 128GB 2x64GB kit matches the board's DDR5 5600 registered ECC specification; select it when you need the full 128GB capacity, otherwise choose a smaller validated kit that follows the same 2Rx4 1.1V RDIMM profile.

What does the 5600 CL46 rating mean once the modules are running in the server?

The modules will operate at DDR5 5600 MT/s with a CAS latency of 46 cycles at 1.1V, delivering the rated bandwidth and error-correcting stability the Supermicro H14SST-G memory controller expects.
