1.5 TB DDR5 ECC RDIMM kit for Supermicro H14SHM

This 1.5 TB kit contains twelve 128 GB DDR5 4800 MHz Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H14SHM motherboard expects. It is intended for administrators who need maximum supported capacity in every slot of that specific platform.

DDR5-4800 Registered ECC limits

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V using a 2Rx4 registered layout that offloads the memory controller so all twelve slots can operate at full capacity. ECC corrects single-bit errors on the fly to prevent silent data corruption. The 288-pin RDIMM form factor is mandatory; UDIMM or SODIMM modules will not fit or function in this board.

Upgrade from partial or lower-capacity populations

Replacing a partially filled configuration or smaller RDIMMs with this fully populated 1.5 TB kit lets the server address the full memory ceiling the H14SHM supports. The jump is worth it when workloads demand the maximum registered ECC capacity the board can accept and the population rules allow all twelve slots to be used.

Questions about this item

Should I buy the 12-module 1.5TB kit or a smaller capacity?

The kit contains 12 modules of 128GB each for a total of 1.5TB. Choose this kit only if your Supermicro H14SHM motherboard supports 12 DIMM slots and the manual lists 128GB RDIMMs in the approved population order.

What does the 4800MHz rating mean once installed in the H14SHM?

The DDR5-4800 (PC5-38400) speed is the rated data rate. With 12 registered ECC modules installed, the memory controller will run the full kit at 4800MHz provided the motherboard firmware and CPU support that frequency at full population.

Is the 288-pin RDIMM interface compatible with the H14SHM and what limits apply?

Yes, the 288-pin RDIMM form factor matches the H14SHM slots. Registered buffering and ECC are required by this board; the 2Rx4 rank structure and 1.1V voltage must match the platform's memory-controller limits for full 1.5TB operation.
