Exact-match upgrade kit

This 1TB kit contains eight 128GB DDR5 RDIMM modules rated at 4800MHz PC5-38400 with CL40 latency and 1.10V operation. Registered ECC architecture with 2Rx4 organisation ensures full-capacity recognition and single-bit error correction on the Supermicro H13SST-G motherboard.

Registered form factor and pinout

The 288-pin RDIMM form factor matches the board's registered memory slots and cannot be used in systems that require UDIMM or SODIMM modules. Buffered signalling offloads the memory controller so all eight slots can run fully populated at the rated speed without signal degradation.

Verify population rules and capacity limits

Server memory support varies by model, so check the motherboard manual for approved DIMM population order, maximum capacity per slot and any BIOS version requirements before ordering. This kit is built for the H13SST-G and will not fit platforms that use a different DDR generation or unregistered memory.

Questions about this item

What DDR5 speed and PC5 rating does this kit run at?

The kit operates at DDR5 4800, which corresponds to the PC5-38400 standard.

How many 288-pin RDIMM slots are required on the Supermicro H13SST-G?

This is an 8-module kit of 128 GB each, so eight 288-pin RDIMM slots must be available and populated.

What is the correct population order when installing all eight modules?

Follow the motherboard manual's approved DIMM population sequence for the H13SST-G to ensure the memory controller recognises the full 1 TB capacity.
