Capacity and purpose

This 384 GB kit contains twelve 32 GB DDR5 6400 ECC RDIMM modules built for the Supermicro H14SSL-NT motherboard. The registered design and 2Rx8 organisation let every slot run fully populated at the rated speed of 6400 MT/s with CL52 latency at 1.1 V.

Who this suits and who it does not

It suits administrators upgrading that specific Supermicro platform to its maximum supported capacity with registered ECC memory. Buyers who need unbuffered UDIMMs, SODIMM form factors, non-ECC modules, or a different speed or voltage should look elsewhere.

What to verify before ordering

Confirm the motherboard manual approves 384 GB total capacity and the required 12-module population order for this board. Ensure the system BIOS is current enough to initialise all twelve registered DIMMs at DDR5 6400. Check that your chassis and CPU cooler leave enough clearance for the full 288-pin module height.

Questions about this item

What motherboard must I already own for this 12-module kit to be recognised at full 384GB capacity?

The kit is validated for the Supermicro H14SSL-NT motherboard; the board's memory controller expects DDR5-6400 registered ECC RDIMMs at 1.1V with CL52 timing.

Will these 2Rx8 registered DIMMs work if I keep older DDR5 modules in the remaining slots?

Mixing ranks or speeds can prevent full-speed operation; the board's population rules should be followed and all slots ideally filled with identical 2Rx8 DDR5-6400 RDIMMs.

How can I verify the ECC function is active after installing all 12 modules?

Enter the BIOS and confirm ECC is enabled, then check the OS reports the full 384GB with corrected-error counters incrementing without uncorrectable errors.
