Exact-match 512GB DDR5 kit

This 512GB kit contains eight 64GB DDR5 4800 registered ECC RDIMMs built for the Supermicro H13DSG-O-CPU motherboard. Each module runs at 1.1V with CL40 timing and a 2Rx4 organisation that matches the board's memory controller requirements. The registered architecture allows full population of every slot at rated capacity and speed.

Thermals noise and power

Operating at 1.1V keeps power draw low across all eight modules in normal server workloads. No heat spreaders are fitted, so airflow through the chassis manages thermals without added acoustic contribution from the memory itself. Registered buffering reduces electrical load on the memory controller during typical operation.

Sustained load behaviour

ECC corrects single-bit errors on the fly during continuous operation, preventing silent data corruption that could otherwise accumulate over long runs. The registered design maintains signal integrity when all channels remain fully populated under sustained throughput. Consult the motherboard manual for approved population order and maximum supported capacity before installation.

Questions about this item

How do I install the eight 64 GB RDIMMs in the Supermicro H13DSG-O-CPU and which population step is most often missed?

Fill all eight DDR5 slots following the motherboard manual's exact population sequence; the step most often missed is skipping the prescribed order, which prevents the board from recognising the full 512 GB at 4800 MT/s.

What maintenance or replacement will the 2Rx4 registered ECC modules need over their service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement is only needed if a DIMM fails, which the lifetime warranty covers.

What limit appears first when the kit runs at 4800 MT/s CL40 under sustained load?

The CAS latency of 40 cycles at 1.10 V sets the timing boundary; the registered buffer and ECC logic keep every slot stable at the rated 4800 MT/s before any other bottleneck emerges.
