Server memory kit for Supermicro H14DSH

This 512GB kit contains eight 64GB DDR5 registered ECC RDIMM modules rated at 6400MHz with CL52 timing and 1.1V operation. It is built for the Supermicro H14DSH motherboard and matches the exact rank, voltage, and timing the memory controller expects.

Installing eight registered DIMMs

The 288-pin RDIMM form factor fits only the slots defined by the H14DSH population rules; UDIMM or SODIMM modules will not seat. Follow the motherboard manual for approved slot order and capacity limits before inserting any module.

DDR5 registered ECC limits

Registered architecture offloads the memory controller so every slot can run fully populated, while ECC corrects single-bit errors on the fly. Maximum capacity and speed depend on the specific CPU and BIOS revision installed in the server.
