Supermicro H14SHM memory kit

This 384GB kit contains twelve 32GB DDR5 RDIMMs built for the Supermicro H14SHM motherboard. It targets administrators who must populate every slot with registered ECC memory that the board recognises at full capacity.

Registered ECC stability

Each module uses a 288-pin registered design that buffers address and command signals so the memory controller stays stable across all twelve slots. ECC corrects single-bit errors on the fly, preventing silent data corruption during long production runs.

4800 MT/s at CL40

The kit runs at DDR5-4800 (PC5-38400) with a CAS latency of 40 and 1.1V, matching the exact speed, timing and voltage the H14SHM memory controller expects for full-rated operation.
