Exact-match 32 GB DDR5 RDIMM

This NEMIX RAM module is a 32 GB DDR5 4800 registered ECC RDIMM built to the 2Rx8 CL40 1.10 V specification. It plugs into a 288-pin slot and matches the memory controller expectations of the Supermicro H13SST-G motherboard so the server recognises full capacity at rated speed.

Suited for populated Supermicro H13SST-G servers

The registered design offloads the memory controller allowing every slot to run fully populated while ECC corrects single-bit errors on the fly. Builders who need unbuffered UDIMMs or laptop SODIMMs should look at something else because this module uses the 288-pin RDIMM form factor only.

2Rx8 CL40 1.10 V DDR5 4800 specification

The single specification that decides fitment is the 2Rx8 CL40 1.10 V DDR5 4800 registered ECC profile. Your system manual must list this exact rank voltage and timing combination for the module to be recognised at full capacity and rated speed.

Questions about this item

How do I install the 288-pin RDIMM in the Supermicro H13SST-G, and which slot order does the manual require?

Align the module's key notch with the slot, press straight down until both side clips lock, then follow the board's DIMM population sequence shown in the motherboard manual to ensure the 2Rx8 registered ECC kit is recognised at 4800 MT/s.

What maintenance will this 32 GB DDR5 ECC RDIMM need over its service life?

No scheduled maintenance is required; the registered ECC design corrects single-bit errors on the fly, and the module has no heat spreader or moving parts to service.

What limit appears first when the RDIMM runs fully populated at 4800 MT/s under sustained load?

The memory controller's maximum supported capacity and population rules become the limiting factor before the CL40 1.10 V modules reach any thermal or electrical ceiling.
