  • Validated for Supermicro H14SSL-NT with 288-pin RDIMM form factor and 2Rx4 organisation

Exact-match DDR5 kit for Supermicro H14SSL-NT

This 1.5 TB kit contains 12 modules of 128 GB each, built as 288-pin DDR5 RDIMMs rated at 5600 MT/s with CL46 timing and 1.10 V operation. Registered ECC architecture ensures the memory controller sees every module at full speed and capacity.

Suited for fully populated Supermicro H14SSL-NT

Designed for administrators who need maximum registered ECC capacity on this specific motherboard. Builders using UDIMM or SODIMM platforms, or boards with different population rules, should look elsewhere.

Handles 1.5 TB across 12 slots at rated DDR5-5600

The 2Rx4 organisation and registered buffering allow every slot to run fully populated without down-clocking. Capacity stops at 1.5 TB; larger configurations require a different motherboard or memory topology.

Questions about this item

Does the Supermicro H14SSL-NT motherboard need all twelve 288-pin DDR5 slots filled for this 1.5 TB kit to operate?

The kit contains twelve 128 GB modules; the H14SSL-NT has twelve DDR5 RDIMM slots, so full population is required to reach the rated 1.5 TB capacity.

Will these 1.1 V CL46 registered ECC modules run at DDR5-5600 if I keep older DDR5-4800 RDIMMs in the same server?

Mixing speeds forces all channels to the slowest installed module, so the 5600 MT/s kit would downclock to 4800 MT/s alongside the older RDIMMs.

How can I confirm the kit is running at its rated DDR5-5600 CL46 1.1 V settings after installation?

Enter the BIOS or use a tool such as dmidecode to verify each DIMM reports 5600 MT/s, CAS 46, 1.1 V and registered ECC status.
