System-specific DDR5 upgrade

This 256GB kit contains four 64GB DDR5 RDIMMs built for the Supermicro H14SSL-NT motherboard. It targets administrators who need to maximise the memory capacity of that specific platform without mixing modules.

Registered ECC with 2Rx4 organisation

The modules run at 5600 MT/s with CL46 latency at 1.10V and use a 2Rx4 rank layout. Registered buffering and ECC are mandatory for this board; the kit matches those requirements exactly so the controller recognises the full 256GB at rated speed.

Low-voltage operation without heat spreaders

At 1.10V the DIMMs draw minimal power and run cool enough to operate without heat spreaders in a properly ventilated server chassis. Registered buffering also reduces electrical load on the memory controller during sustained workloads.

Questions about this item

What does the 5600 MT/s rating mean once the kit is installed in a Supermicro H14SSL-NT?

The modules run at DDR5-5600 (PC5-44800) with CL46 latency at 1.1 V, delivering the exact speed and timing the board's memory controller expects when all four slots are populated.

How does the registered ECC interface affect real-world capacity and stability on this motherboard?

Registered (buffered) architecture offloads the memory controller so every slot runs fully populated at the full 256 GB, while ECC catches and corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

What physical slot and form-factor does this 4×64 GB kit require on the H14SSL-NT?

Each 64 GB module is a 288-pin DDR5 RDIMM; the kit fills four DIMM slots in the population order specified by the Supermicro H14SSL-NT manual.
