Exact-fit DDR5 upgrade for Supermicro H13SST-GC

This 48GB DDR5 4800 PC5-38400 registered ECC RDIMM is built to the precise rank, voltage and timing the Supermicro H13SST-GC memory controller expects. It delivers 48GB at 1.1V with CL40 latency in a 2Rx8 configuration. The module is intended for servers and workstations that require registered memory with error correction.

Straightforward DIMM installation

The 288-pin RDIMM seats in the standard DDR5 slots on the H13SST-GC board. Because the platform uses registered memory, every slot can run fully populated at rated speed when the correct population order is followed. The most common issue is inserting modules in the wrong sequence or mixing ranks, which prevents the system from recognising the full capacity. No heat spreader is fitted, so clearance is minimal, but the motherboard manual must be consulted for the approved slot order before fitting.

Verify capacity limits

Check the Supermicro H13SST-GC manual for the maximum supported capacity per DIMM and the required population sequence for 2Rx8 registered modules. Confirm the board's qualified vendor list includes this specification and that the BIOS version in use supports the full 48GB density. Systems that only accept unbuffered UDIMMs or SODIMMs cannot use this RDIMM.

Questions about this item

How do I confirm the module runs at 4800 MT/s with CL40 after installing it in the Supermicro H13SST-GC?

Enter the BIOS or use a hardware-info utility and verify the memory speed reads 4800 MT/s and CAS latency shows CL40; the registered ECC design ensures the controller recognises the 2Rx8 rank at its rated timing.

What comes in the package and is anything else required for installation?

The box contains a single 48 GB 288-pin DDR5 RDIMM; no heat spreader or extra cables are included, and no separate components are needed beyond a compatible DIMM slot on the motherboard.

Which capacity or version should I choose for the H13SST-GC?

This part number MR38400-4828K1 is a 48 GB DDR5-4800 2Rx8 registered ECC module built to the board's exact voltage and rank requirements; select it when your configuration calls for a 48 GB registered DIMM.
