Server Memory Kit

This 768GB kit contains twelve 64GB DDR5 RDIMM modules rated at 6400 speed with CL52 latency and 1.1V operation. It is built for the Supermicro H14SHM motherboard and targets enterprise servers that require registered ECC memory for data integrity.

Verify Compatibility

Consult the Supermicro H14SHM manual for supported memory capacities, approved DIMM population order, and installation steps before ordering. The motherboard requires 288-pin registered RDIMMs; unbuffered UDIMMs or SODIMMs will not fit or function in this platform.

Build Integration

Registered architecture offloads the memory controller so all twelve slots can run fully populated at the rated 6400 speed while ECC corrects single-bit errors on the fly. The modules have no heat spreaders, so ensure the server chassis provides adequate airflow across the DIMM banks.

Questions about this item

What comes in the box and does it need anything else to install?

The kit includes twelve 64 GB DDR5 6400 CL52 2Rx4 1.1 V registered ECC RDIMMs for a total of 768 GB. No extra parts are required, but verify the Supermicro H14SHM population order in the motherboard manual before installing.

Why choose the 12 × 64 GB kit over smaller capacities?

This 768 GB kit fully populates the H14SHM with the exact rank, voltage and timing the board expects, so every slot runs at the rated DDR5 6400 speed without down-clocking.

What does the DDR5 6400 CL52 rating mean once the modules are in the server?

The memory will operate at 6400 MT/s with a CAS latency of 52 cycles at 1.1 V, delivering the bandwidth and error-correction the H14SHM memory controller is designed for.
