Exact-Match Server Kit

This NEMIX RAM kit provides 576GB of DDR5 memory across twelve 48GB modules built for the Supermicro H13SSW motherboard. The 288-pin Registered ECC RDIMM format matches the board's required form factor and population rules so the system recognises the full capacity at the rated DDR5-6400 speed.

Enterprise Thermals and Power

Registered architecture reduces electrical load on the memory controller allowing all twelve slots to run fully populated at 1.1V without exceeding platform limits. ECC corrects single-bit errors in real time preventing silent data corruption and unplanned reboots in production workloads.

Capacity and Compatibility Upgrade

The kit replaces smaller or mixed-capacity DDR5 RDIMM sets when the workload demands the maximum supported density per slot. It is not suited for systems that require unbuffered UDIMMs, SODIMM form factors, or voltages other than 1.1V.

Questions about this item

How do I install the 12 DDR5 RDIMMs on the Supermicro H13SSW, and which population step is often missed?

Populate all twelve 288-pin slots following the motherboard manual's exact DIMM order; the step most often missed is verifying the 2Rx8 rank layout and 1.10V setting in BIOS so the controller recognises the full 576 GB at 6400 MT/s.

What maintenance or replacement will the 576 GB DDR5 ECC RDIMM kit need later?

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

What limit appears first when the 12x48 GB DDR5 6400 CL52 kit runs sustained workloads?

The registered buffer and 1.10V operation keep electrical load low, so the first practical limit is the motherboard's maximum supported capacity and slot count, not thermal throttling or signal degradation.
