384GB DDR5 ECC RDIMM kit for Supermicro H14SSL-NT

This 384GB kit contains six 64GB DDR5 registered ECC RDIMMs built for the Supermicro H14SSL-NT motherboard. Each module runs at 4800 MT/s with CL40 latency at 1.10V. The 2Rx4 organization and registered buffer let the memory controller address every slot when fully populated.

DDR5-4800 registered ECC limits

DDR5 at 4800 MT/s sets the baseline bandwidth for this platform; the registered buffer adds one cycle of latency but allows full-slot population without signal degradation. ECC corrects single-bit errors on the fly, yet it cannot recover multi-bit failures. The 288-pin RDIMM form factor fits only boards wired for registered memory.

Six 64GB modules fill the board

Six 64GB DIMMs deliver 384GB total capacity, the maximum this kit provides. Population rules on the H14SSL-NT may restrict which slots can be used together, so the full 384GB is only available when the manual's approved configuration is followed. Beyond this kit, larger per-module densities would be required to increase capacity further.

Questions about this item

Should I choose the 384GB kit or a smaller capacity for my Supermicro H14SSL-NT?

The 384GB kit provides six 64GB modules. Choose it only if your board's population rules and CPU support allow all slots to run at DDR5 4800. A smaller kit may be required for full-speed operation with certain processors.

What does the DDR5 4800 rating deliver once installed in the H14SSL-NT?

The modules run at 4800 MT/s with CL40 latency at 1.1V. Registered ECC buffers the command bus so all six slots operate at rated speed without downclocking, while ECC corrects single-bit errors in real time.

How does the 288-pin RDIMM interface limit performance on this platform?

The 288-pin RDIMM form factor is mandatory for the H14SSL-NT. It caps the kit to DDR5 4800 (PC5-38400) dual-rank operation; UDIMM or SODIMM modules will not fit or function in this server board.
