Exact-match DDR5 RDIMM kit

This 384 GB kit contains eight 48 GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H14DSG-O-CPU memory controller expects. It is intended for administrators who need to populate every slot at full capacity without manual tuning.

Registered DDR5 population limits

Registered architecture offloads the memory controller so all eight slots can run fully populated at the rated 4800 MT/s speed. The motherboard's own population rules still dictate which slots must be filled first and the maximum capacity per channel.

288-pin RDIMM build implications

Modules use a standard 288-pin RDIMM form factor without heat spreaders, relying on server chassis airflow for cooling. ECC corrects single-bit errors on the fly to prevent silent data corruption, while the registered buffer adds one cycle of latency that is normal for this class of memory.

Questions about this item

Should I choose the 384GB 8×48GB kit or a smaller capacity for my Supermicro H14DSG-O-CPU?

The 384GB kit provides eight 48GB modules that match the board's 288-pin RDIMM slots and population rules, delivering full capacity at the rated 4800MHz speed.

What does the 4800MHz rating mean once the modules are installed in the server?

The memory controller will run the kit at DDR5-4800 (PC5-38400) with CL40 latency at 1.1V, giving the bandwidth and timing the platform expects when all slots are populated.

How does the registered ECC RDIMM interface affect real-world operation?

Registered buffering offloads the memory controller so every slot runs fully populated at full speed, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
