Exact-fit DDR5 kit for Supermicro H13SSL-NT

This 256 GB kit contains four 64 GB registered ECC DDR5 modules built to the precise 2Rx4 rank, 1.1 V voltage and CL46 timing the H13SSL-NT memory controller expects. It is intended for administrators upgrading that specific server platform to its full supported capacity with modules that will be recognised at rated speed.

Straightforward slot population if the manual is

Each module uses the standard 288-pin RDIMM form factor this board requires, so installation is a matter of seating the sticks in the approved population order. The usual problem is ignoring the motherboard manual’s slot sequence or mixing ranks, which prevents the system from booting or seeing the full 256 GB.

2Rx4 registered ECC at DDR5-5600 is the deciding

The combination of registered buffering, ECC, 2Rx4 organisation and 5600 MT/s speed is what the H13SSL-NT memory controller validates; modules with a different rank, voltage or timing will not train at the rated frequency. Builders who need unbuffered UDIMMs or a different capacity per module cannot use this kit.

Questions about this item

How can I verify the kit is running at DDR5 5600 CL46 after installation?

Enter the BIOS or use a tool like dmidecode to confirm each module shows 5600 MT/s, CL46 timings, 1.10 V, and 2Rx4 registered ECC operation across all four slots.

What is included in the box and do I need any extra parts?

The box contains four 64 GB DDR5 5600 CL46 1.10 V 2Rx4 ECC registered RDIMMs for a total of 256 GB; no additional components are required for installation.

Should I choose this 256 GB (4x64 GB) kit or a different capacity for the Supermicro H13SSL-NT?

Select this 256 GB kit when your workload needs maximum capacity per channel and the motherboard manual confirms 64 GB RDIMM support in a four-module population.
