Exact-match kit for Supermicro H13SST-GC

This 512GB kit ships as four 128GB DDR5 4800 registered ECC RDIMMs built to the memory controller's precise rank, voltage and timing expectations. It targets administrators who need full-capacity population on this specific server board without trial-and-error compatibility issues.

Verify your board's population rules before ordering

Consult the Supermicro H13SST-GC manual for supported capacities per slot, approved DIMM installation order and any BIOS requirements for registered memory. The 288-pin RDIMM form factor will not fit UDIMM or SODIMM slots, and registered modules must match the board's qualified vendor list to initialise correctly.

Registered architecture

Registered buffering offloads the memory controller so all four slots run fully populated at rated speed while ECC corrects single-bit errors on the fly. Modules operate at 1.1V without heat spreaders, so adequate chassis airflow across the DIMM banks is required for sustained operation.

Questions about this item

What does the 512 GB kit contain and is anything else needed?

The kit includes four 128 GB DDR5-4800 CL40 2Rx4 registered ECC RDIMMs at 1.1 V. No extra parts are required for installation.

How do I decide between this 512 GB kit and a smaller capacity?

Choose this 512 GB kit when your Supermicro H13SST-GC motherboard supports full 4-DIMM population and your workloads need the maximum registered ECC capacity.

What does the DDR5-4800 rating mean once the modules are installed?

The modules will run at 4800 MT/s with CL40 latency at 1.1 V, delivering PC5-38400 bandwidth per DIMM when the motherboard populates all four slots.
