System-Specific DDR5 Kit

This 64 GB kit contains four 16 GB DDR5 RDIMMs built for the Supermicro H14SSL-NT motherboard. Each module is a 288-pin registered ECC DIMM rated at 6400 MT/s with CL52 latency. The 1.10 V operating voltage matches the platform's memory controller specification. It is intended for administrators upgrading or populating that specific server board.

Registered ECC Architecture

The single specification that determines fit is the registered ECC RDIMM form factor combined with 1Rx8 rank organisation. The motherboard requires registered modules; unbuffered UDIMMs or SODIMMs will not function. This kit delivers the exact rank, voltage and timing the controller expects so all four slots run at the rated 6400 speed.

Thermals and Power

Modules operate at the standard DDR5 1.10 V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping per-DIMM power draw low during sustained workloads. In a properly ventilated enclosure the kit runs silently with no active cooling required.

Questions about this item

Will the 6400 MT/s speed run at full rate on my Supermicro H14SSL-NT?

The kit is spec-matched to the H14SSL-NT memory controller, so the four 1Rx8 registered DIMMs are recognised at the rated 6400 MT/s when populated per the board's rules.

Does the 288-pin RDIMM registered interface limit how many modules I can install?

Registered architecture offloads the memory controller, allowing all four slots to run fully populated at 64 GB total without signal degradation.

What physical clearance do the 288-pin modules need inside a 1U chassis?

The sticks are standard-height RDIMMs without heat spreaders, fitting the 288-pin slots on the H14SSL-NT without extra vertical clearance.
