Supermicro H14SSL-NT DDR5 RDIMM kit

This 384 GB kit contains six 64 GB DDR5-6400 registered ECC modules built for the Supermicro H14SSL-NT motherboard. The 288-pin RDIMM form factor matches the board's memory slots exactly. Each module runs at 1.1 V with CL52 latency and a 2Rx4 rank layout. The registered buffer lets every slot run fully populated at rated speed.

Who this suits and who should look elsewhere

Server administrators who need the exact capacity, voltage, and timing the H14SSL-NT memory controller expects will find a drop-in upgrade. Builders using consumer motherboards, workstations that require unbuffered UDIMMs, or systems limited to lower densities cannot use this registered ECC kit.

Deciding specification — registered ECC DDR5-6400

The combination of registered buffering, ECC, 6400 MT/s speed, 2Rx4 organization, and 1.1 V operation is what the H14SSL-NT platform requires for full-capacity recognition. If your board calls for a different voltage, rank structure, or unbuffered modules, this kit will not be compatible.

Questions about this item

How can I confirm the 384GB DDR5 kit is running at 6400MHz CL52 after installing it in my Supermicro H14SSL-NT?

Enter the BIOS on first boot and verify the memory speed reads 6400 MT/s with CAS latency 52; the registered ECC modules should also report 384GB total capacity and 1.1V operation.

What ships in the box and do I need any extra parts for the H14SSL-NT?

The package contains six 64GB 288-pin DDR5 RDIMMs for a total of 384GB; no additional cables, brackets or cooling are required for the Supermicro H14SSL-NT motherboard.

Should I choose this 6x64GB kit or a different capacity for the H14SSL-NT?

This 384GB kit (6 x 64GB, 2Rx4, CL52, 1.1V) matches the board's DDR5 RDIMM population rules; select it when you need the full 384GB across six slots.
