Exact-fit DDR5-6400 RDIMM

This 32 GB registered ECC module is built for the Supermicro H13DSH motherboard. It delivers the precise 2Rx8 rank, 1.10 V voltage and CL52 timing the board's memory controller expects for full-capacity operation at rated speed.

Thermals and power draw

Operating at the standard 1.10 V DDR5 voltage, the module draws minimal power per DIMM slot. With no heat spreader fitted, airflow across the PCB handles thermal load in typical server chassis configurations.

Build and daily implications

The 288-pin RDIMM form factor locks into the board's registered DIMM slots and cannot be used in UDIMM or SODIMM systems. Registered buffering offloads the memory controller so every populated slot runs at full capacity, while on-die ECC corrects single-bit errors to prevent silent data corruption.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in the Supermicro H13DSH, and which slot population rule is often missed?

Insert the module into the DIMM slots specified in the H13DSH manual for registered memory, following the exact population sequence; the board requires RDIMMs not UDIMMs, and skipping the prescribed slot order prevents the system from recognising the full 32 GB capacity at 6400 MHz.

What maintenance or replacement will this 1.1 V ECC RDIMM need over its service life?

No routine maintenance is required; ECC corrects single-bit errors automatically, and the module is covered by a lifetime replacement warranty if a hardware fault develops.

What limit appears first when this CL52 2Rx8 kit runs sustained workloads?

The registered buffer and ECC logic keep every slot stable at the rated 6400 MHz speed, so the practical ceiling is the motherboard's maximum supported capacity and population rules rather than a thermal or timing bottleneck.
