Server Memory Upgrade

This 48 GB DDR5 module is built for the Supermicro H13SST-G motherboard and delivers 4800 MHz speed with CL40 latency. Registered ECC architecture and 1.10 V operation provide the stability required for production servers and workstations.

Installation Requirements

The 288-pin RDIMM form factor fits only registered DIMM slots; it will not work in UDIMM or SODIMM sockets. Motherboard manuals dictate the exact population order for 2Rx8 modules, so follow the documented sequence to avoid a no-post condition.

Pre-Order Checklist

Confirm that your H13SST-G system supports 48 GB per slot and the total capacity you intend to install. Verify the approved DIMM population rules and any BIOS version requirements before ordering.

Questions about this item

How can I confirm the 48GB DDR5 4800 CL40 module is running at its rated 4800 speed after installing it in my Supermicro H13SST-G?

Check the BIOS memory information or use a tool like CPU-Z to verify the module reports DDR5-4800 (PC5-38400) with CL40 timings at 1.1V; the registered ECC design ensures full-speed operation when populated per the board's rules.

What exactly ships in the package and do I need any extra brackets, cables or cooling for this 288-pin RDIMM?

The box contains the 48GB DDR5 4800MHz PC5-38400 2Rx8 1.1V CL40 288-pin ECC Registered RDIMM only; no heat spreader is included and none is required, and no additional brackets, cables or adapters are needed for the standard DIMM slot.

My H13SST-G has multiple DIMM slots — should I choose this 48GB 2Rx8 registered kit or a different capacity or rank?

Select this 48GB 2Rx8 Registered ECC RDIMM when your motherboard manual lists 48GB dual-rank registered modules in the qualified vendor list and your target capacity matches the board's maximum per slot and population order.
