128GB DDR5-4800 ECC RDIMM kit

This NEMIX RAM kit provides 128GB of DDR5 server memory as four 32GB Registered DIMMs. Each module runs at 4800MHz with CL40 latency at 1.1V. The 2Rx8 ECC RDIMM design matches the Supermicro H13SSW motherboard requirements for registered, error-correcting memory.

Who this suits and who should look elsewhere

System builders upgrading a Supermicro H13SSW motherboard with validated DDR5 Registered ECC modules. Not for desktop PCs that require unbuffered UDIMMs, laptops needing SODIMMs, or any platform that does not support 288-pin DDR5 RDIMM population rules.

The specification that decides fit

DDR5 4800 Registered ECC RDIMM with 2Rx8 organization at 1.1V CL40. The memory controller must accept this exact rank, voltage, timing, and registered architecture for the kit to be recognized at full capacity and rated speed.

Questions about this item

Should I pick this 128 GB kit or look for a different capacity for my Supermicro H13SSW?

This kit delivers 128 GB across four 32 GB modules, matching the board's RDIMM slot layout and population rules for full-capacity operation.

What does DDR5 4800 actually give me once the modules are installed?

The memory runs at 4800 MT/s with CL40 latency at 1.10 V, providing the rated bandwidth and error-correcting stability the server expects.

Is the 288-pin RDIMM interface the right one for my H13SSW, and does it limit speed or capacity?

Yes, the 288-pin Registered DIMM form factor is exactly what the H13SSW requires; it supports the full 4800 MT/s speed and 128 GB capacity with ECC enabled.
