Exact-Match Server Upgrade

This 1.5TB kit contains twelve 128GB DDR5 RDIMMs built to the exact rank, voltage, and timing the Supermicro H13SST-G memory controller expects. The modules are recognised at full capacity and run at their rated 4800MHz speed without manual tuning. Registered ECC architecture keeps every slot stable when fully populated.

Replaces Mismatched Or Partial Kits

The kit upgrades a server running on smaller-capacity DIMMs or mixed-rank modules that force the controller to down-clock or limit total memory. The jump is worth it when your workload needs the full 1.5TB address space at native DDR5-4800 throughput and you cannot tolerate silent data errors.

DDR5 RDIMM Platform Constraints

DDR5 RDIMMs require a motherboard wired for 288-pin registered memory and a BIOS that supports the 2Rx4 organisation at 1.1V. The Supermicro H13SST-G must be configured with the approved population order; other boards, UDIMM slots, or SODIMM sockets will not accept these modules.

Questions about this item

Does the 288-pin DDR5 RDIMM form factor fit the Supermicro H13SST-G motherboard slots?

Yes, the 288-pin Registered DDR5 RDIMM form factor matches the slots required by the Supermicro H13SST-G motherboard.

What is the correct population order when installing all 12 modules on the Supermicro H13SST-G?

Follow the motherboard manual's approved DIMM population sequence for full 12-module installation to ensure the memory controller recognizes the entire 1.5TB capacity at DDR5-4800 speed.

Will the ECC Registered RDIMM modules require any firmware updates or scheduled replacement?

No firmware updates are needed for the memory modules themselves; ECC corrects single-bit errors on the fly, and the modules are backed by a lifetime replacement warranty if a hardware fault ever occurs.
