Exact-Match Server Upgrade

This 576GB kit provides twelve 48GB DDR5 5600 RDIMMs validated for the Supermicro H13SSW motherboard. Each module is a registered ECC DIMM with 2Rx8 organisation and CL46 timing at 1.10V. The precise rank, voltage and latency match the board's memory controller requirements so the full capacity is recognised at rated speed. Builders populating every slot on this platform get the exact configuration the firmware expects.

Thermals Noise Power

Registered buffering reduces electrical load on the memory controller, allowing all twelve slots to run fully populated without extra stress. The modules operate at the standard 1.10V DDR5 voltage and carry no heat spreaders, relying on server chassis airflow for cooling. Power draw scales with the 5600 MT/s data rate and 48GB density per DIMM. Acoustic output is determined by the system fans rather than the memory itself.

Sustained Load Behaviour

ECC circuitry corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. Registered architecture keeps signal integrity stable across all populated channels when the memory subsystem is saturated. The kit is specified for continuous operation at DDR5 5600 with CL46 latency. Buyers needing capacities beyond 576GB or different DIMM types must consult the motherboard manual for supported configurations.

Questions about this item

How do I install the 12 DDR5 RDIMM modules in the Supermicro H13SSW, and which population step is often missed?

Populate all 12 slots following the motherboard manual's exact DIMM order; the step most often missed is verifying the approved population sequence for full 576GB capacity before powering on.

What maintenance or replacement will the 2Rx8 ECC RDIMM kit need over its service life?

The modules have no moving parts or heat spreaders; maintenance is limited to keeping server airflow clean, and replacement occurs only if ECC logs report uncorrectable errors on a specific DIMM.

What limit appears first when the 576GB kit runs sustained workloads at DDR5 5600 CL46?

The registered buffer and 1.1V operation keep signal integrity stable, so the first limit is typically the platform's maximum memory-controller throughput rather than the DIMMs themselves.
