Exact DDR5-4800 ECC RDIMM kit for Supermicro

This 128 GB kit contains two 64 GB registered DIMMs built to the DDR5-4800 standard with CL40 timing and 1.1 V operation. It is designed for servers that require ECC Registered memory in a 288-pin form factor.

Registered 2Rx4 architecture matches the board's

The modules use a 2Rx4 organisation and registered buffering so the memory controller can address every slot at full rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption.

288-pin RDIMMs install like standard server DIMMs

Align the key notch with the slot and press until the latches engage; no heat spreader is fitted so clearance is generous. Verify the motherboard manual for approved population order and maximum supported capacity before fitting.

Questions about this item

What does the DDR5-4800 speed rating mean when the modules are installed in a Supermicro H14SSL-N?

The memory controller will initialise each 64 GB RDIMM at 4800 MT/s with CL40 timings and 1.1 V, so the kit runs at its rated data rate across both channels.

How does the 288-pin registered ECC interface affect usable bandwidth and error handling?

Registered buffering reduces electrical load on the memory controller, allowing full-speed operation with both slots populated, while on-die ECC corrects single-bit errors before they reach the OS.

What physical clearance and slot requirements must the H14SSL-N meet for this 2Rx4 kit?

The board needs two adjacent 288-pin DDR5 RDIMM slots with enough height clearance for modules without heat spreaders, and the population order must follow the manual's 2Rx4 guidelines.
