NEMIX RAM 64GB 4x16GB DDR5 4800 ECC RDIMM Supermicro H13SSW memory upgrade

Exact-fit DDR5 upgrade for Supermicro H13SSW

This 64 GB kit contains four 16 GB DDR5-4800 registered ECC RDIMMs built to the precise 1Rx8, 1.1 V, CL40 specification the H13SSW memory controller expects. Each module is a 288-pin RDIMM using major OEM DRAM from Samsung, Micron or Hynix so the server recognises the full capacity and runs at its rated speed without manual tuning.

Thermals noise and power in normal operation

Registered buffering offloads the memory controller, allowing all four slots to run fully populated at the rated 1.1 V without extra voltage overhead. The modules carry no heat spreaders, relying on standard server airflow to keep temperatures in check while the ECC function corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

What the kit contents change for the installer

The package delivers exactly four matched RDIMMs and nothing else — no cables, brackets, software licences or configuration tools. Because the kit matches the board’s population rules, the installer simply follows the motherboard manual’s slot order, seats the modules and powers on; no additional parts or downloads are required to reach the rated 64 GB at DDR5-4800.
