Exact-fit DDR5 RDIMM for Supermicro H13SSL-N

This 48GB DDR5 4800 CL40 registered ECC module is built to the precise rank, voltage and timing the Supermicro H13SSL-N memory controller expects. The 2Rx8 288-pin RDIMM operates at 1.1V and runs at its rated speed when installed in a compatible server.

Who this suits and who should look elsewhere

Designed for administrators upgrading a Supermicro H13SSL-N motherboard that requires registered ECC DDR5 RDIMMs with a 2Rx8 organisation. Builders needing unbuffered UDIMMs, SODIMMs, non-ECC memory or a different capacity or speed should select another module.

Installation ease and common issues

The 288-pin RDIMM seats in the standard DDR5 server slot; no heat spreader is fitted, so clearance is minimal. Common issues include ignoring the motherboard's population order, mixing ranks or voltages, and forgetting to enable ECC in the BIOS. Consult the system manual for the approved DIMM sequence before installation.

Questions about this item

What motherboard must I already have for this 48GB DDR5 4800 CL40 2Rx8 ECC Registered RDIMM to work?

This module is verified for the Supermicro H13SSL-N motherboard. It uses the 288-pin RDIMM form factor that board requires, so it fits the correct slots and follows the board's population rules.

Can I keep my existing DDR5 4800 Registered ECC modules and add this 48GB 2Rx8 kit alongside them?

Yes, provided the other modules are also DDR5 4800 Registered ECC. The memory controller will run all populated slots at the lowest common speed and timing, so matching voltage (1.1V) and registered architecture keeps the system stable.

How can I confirm the 48GB DDR5 4800 CL40 kit is running at its rated speed after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report 4800 MT/s (PC5-38400), CL40 latency, 1.1V voltage, and the full 48GB capacity per module.
