Server Memory Kit

This 64 GB kit contains four 16 GB DDR5 RDIMMs built for the Supermicro H13SST-GC motherboard. Registered ECC architecture offloads the memory controller and corrects single-bit errors, keeping production workloads stable when every slot is populated.

Sustained Load Behavior

Registered buffering maintains signal integrity across all four modules during continuous operation, allowing the full 64 GB to run at the rated 4800 MT/s without throttling. ECC correction runs transparently in the background, preventing silent data corruption during long compute runs.

DDR5 Interface Limits

The DDR5 4800 standard provides 38400 MB/s of peak bandwidth per module at 1.1 V. CL40 timing and 1Rx8 rank organisation define the latency floor the controller must meet; exceeding the board's validated population rules will reduce speed or prevent boot.

Questions about this item

How much power does this 4800MHz DDR5 ECC RDIMM kit draw when the server runs continuously?

Each 16GB module operates at 1.1V, so the four-stick kit runs at the standard DDR5 voltage without extra power overhead.

What motherboard slot and memory controller features are required for this 288-pin Registered kit?

The board must provide DDR5 RDIMM slots and a memory controller that supports Registered ECC modules at 4800MHz with 1Rx8 organisation.

Can I mix this 1Rx8 CL40 kit with existing DDR5 RDIMMs of a different rank or speed on the same Supermicro H13SST-GC?

Mixing ranks or speeds is not recommended; the board's memory population rules expect matched 1Rx8 CL40 modules for stable operation at full capacity.
