Exact-fit DDR5 ECC RDIMM kit

This 256GB kit (4 x 64GB) delivers DDR5 5600 (PC5-44800) registered ECC memory at CL46 and 1.1V. It is built for the Supermicro H14SHM motherboard where 288-pin RDIMM form factor and 2Rx4 rank layout are required for full-capacity recognition.

Registered buffer and ECC limits

Registered architecture reduces electrical load on the memory controller so all four slots can run populated at rated speed. ECC corrects single-bit errors on the fly, but the kit cannot add ECC to a platform that lacks ECC support in its firmware or CPU.

Upgrade from partial or slower kits

Replaces smaller-capacity RDIMM sets or lower-speed DDR5 modules that leave slots empty or force down-clocking. The jump is worth it when the workload needs maximum registered DIMM capacity and the board's population rules allow four 64GB 2Rx4 modules at once.

Questions about this item

Should I choose the 256GB kit with four 64GB modules or a different capacity for my Supermicro H14SHM?

The kit provides 256GB total using four 64GB modules. Check your motherboard manual for supported capacities and the approved DIMM population order before deciding.

What does the DDR5-5600 (PC5-44800) speed rating deliver once installed in the H14SHM?

The modules run at 5600 MT/s with CL46 latency at 1.1V. Registered ECC architecture lets every slot run fully populated at the rated speed while correcting single-bit errors on the fly.

How does the 288-pin RDIMM interface and registered ECC design affect real-world limits?

The 288-pin RDIMM form factor fits the H14SHM's DDR5 slots. Registered buffering offloads the memory controller so all four slots operate at full capacity, and ECC prevents silent data corruption.
