Exact-match DDR5-6400 RDIMM kit

This 192GB kit contains six 32GB DDR5-6400 CL52 registered ECC RDIMMs that run at 1.1V. It is built to the precise rank, voltage and timing the Supermicro H14SSL-NT memory controller expects so the server recognises the full capacity and operates at the rated 6400 MT/s speed.

Suits fully populated H14SSL-NT servers

Ideal for administrators upgrading a Supermicro H14SSL-NT motherboard that requires 288-pin registered ECC modules and can populate all six slots with 2Rx8 RDIMMs. Not for systems that accept only unbuffered UDIMMs, SODIMM form factors, or lower-density DIMMs, nor for boards limited to fewer populated slots.

Verify manual before ordering

Check the H14SSL-NT manual for supported total capacity, approved DIMM population order and any BIOS version requirements for six-module configurations. Confirm the board accepts 2Rx8 registered ECC RDIMMs at 1.1V and that the memory controller can run all channels at DDR5-6400 with this density.

Questions about this item

Does my Supermicro H14SSL-NT motherboard need all six DDR5 slots free to install this 192GB kit?

The kit provides six 32GB RDIMMs that fill every DDR5 slot on the H14SSL-NT, so no other modules should remain installed when you populate the full 192GB configuration.

Will the registered ECC design of these modules work with any unbuffered DIMMs I might leave in the system?

No, the H14SSL-NT requires registered RDIMMs only; mixing unbuffered UDIMMs with this 2Rx8 registered kit will prevent the server from posting.

How can I confirm the kit is running at its rated DDR5-6400 CL52 1.1V after installation?

Enter the BIOS and verify the memory speed shows 6400 MT/s, CAS latency reads 52, and voltage reports 1.1V across all six populated slots.
