Exact-match 768GB DDR5-4800 kit for Supermicro

This 768GB kit contains eight 96GB DDR5-4800 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13SSF memory controller expects. Each module runs at 1.1V with CL40 latency in the required 288-pin RDIMM form factor. The kit is designed for servers that need maximum capacity across every slot.

Thermals noise and power draw in normal use

Operating at 1.1V, the modules draw minimal power for their density and run without heat spreaders in standard server airflow. Registered buffering reduces electrical load on the memory controller when all eight slots are populated. No active cooling is included, so chassis airflow must handle the thermal load.

What the bundled accessories

The package supplies only the eight RDIMMs; no cables, brackets or software utilities are included. Compatibility is validated against the H13SSF motherboard population rules, so the kit installs directly into the approved slots. Buyers who need UDIMM or SODIMM form factors, or capacities beyond the board's supported limits, cannot use this kit.

Questions about this item

How do I install the 8x96GB DDR5 RDIMM kit in my Supermicro H13SSF and which step is most often missed?

Populate all eight slots following the motherboard manual's DIMM population order; the step most often missed is verifying the exact slot sequence before seating the modules.

What maintenance or replacement will the 768GB DDR5 ECC Registered kit need over its service life?

The modules have no heat spreaders and require no scheduled maintenance; ECC corrects single-bit errors on the fly, and a lifetime replacement warranty covers any module that fails.

What is the first limit I will hit when running the 4800MHz CL40 DDR5 kit at full load continuously?

The CAS latency of CL40 at DDR5-4800 sets the timing ceiling you will encounter first under sustained use.
