Exact-match upgrade for Supermicro H13SSF

This 768GB kit delivers six 128GB DDR5 RDIMMs rated at 4800MHz with CL40 latency and 1.1V operation. Registered ECC architecture ensures the memory controller recognises every module at full capacity and rated speed. It is built for servers that require 2Rx4 registered DIMMs and will not accept unbuffered or SO-DIMM alternatives.

Simple slot installation with population rules

Each 288-pin module seats in the standard DDR5 RDIMM slots, but the H13SSF motherboard enforces a specific population order that must be followed. The manual lists approved capacities and slot sequences; skipping a step can leave capacity unseen or prevent the system from posting. No heat spreaders are fitted, so clearance around adjacent components is generous.

Sustained enterprise stability under full load

Registered buffering offloads the memory controller so all six slots run fully populated without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during continuous operation. The 1.1V DDR5 baseline keeps power draw consistent across extended workloads.

Questions about this item

How can I confirm the kit is running at 4800MHz with CL40 after installation?

Enter the BIOS or use a tool such as CPU-Z to verify the memory frequency reads 4800MHz and the CAS latency shows CL40; the registered ECC design also lets the server log corrected errors during POST.

What does the 768GB kit contain and is anything else required?

The package includes six 128GB DDR5 288-pin RDIMM modules; no extra cables, brackets or cooling parts are needed for installation.

Which capacity should I choose if my Supermicro H13SSF manual lists 128GB per slot as the maximum?

Select this 768GB kit (six 128GB DIMMs) to fully populate every slot at the board's rated per-slot limit.
