Exact-match DDR5 RDIMM upgrade

This 32 GB DDR5 4800 module is built to the precise rank, voltage, and timing the Supermicro H13SSL-NT motherboard expects. It installs as a 288-pin Registered DIMM with ECC and CL40 latency at 1.1 V. The memory controller recognises the part at full capacity and rated speed without manual tuning. Builders who need a different form factor or non-ECC memory cannot use this kit.

Sustained enterprise stability

Registered architecture offloads the memory controller so every populated slot runs at the rated 4800 MT/s continuously. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 2Rx8 organisation keeps signal integrity high across full population. Workloads that exceed the board's approved DIMM count or require unbuffered modules will not be supported.

Verified fitment and daily handling

The 288-pin RDIMM keying matches the H13SSL-NT slots exactly, so the module seats securely without forcing. No heat spreader is fitted, leaving the chips exposed for direct airflow in dense server chassis. Population order must follow the motherboard manual to activate all channels correctly. Buyers who need taller heatsinks or tool-less retention clips should verify clearance before ordering.

Questions about this item

How much heat and power does the 1.1V DDR5 4800 RDIMM draw when the server runs all day?

The module operates at 1.10V with no heat spreader, so it relies on chassis airflow to stay cool under continuous load.

What must my Supermicro H13SSL-NT already have for this 288-pin RDIMM to work?

The board needs an available DDR5 RDIMM slot and a BIOS that supports 2Rx8 registered ECC modules at 4800 MT/s.

Will this 32GB 2Rx8 CL40 kit run alongside older DDR5 sticks I keep in the other slots?

Mixing ranks or timings can force the controller to downclock; populate slots per the motherboard manual for matched 2Rx8 modules at CL40.
