NEMIX RAM 384GB (6x64GB) DDR5 4800 CL40 2Rx4 ECC RDIMM ASRock Rack SIENAD10HM3 memory upgrade

Exact-match DDR5-4800 kit for ASRock Rack

This 384 GB kit contains six 64 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 timings and 1.10 V operation. Registered ECC architecture and 2Rx4 organization match the memory controller expectations of the ASRock Rack SIENAD10HM3 motherboard so the full capacity is recognized at rated speed. It is built for servers that require registered modules rather than unbuffered or SODIMM alternatives. Buyers who need unregistered UDIMMs or a different pin count cannot use this kit.

Registered ECC design limits electrical load per

The registered buffer reduces the electrical load on the memory controller when all slots are populated, allowing stable operation across the full six-module configuration. ECC circuitry detects and corrects single-bit errors during normal operation, preventing silent data corruption and unplanned reboots. Modules run at the standard 1.10 V DDR5 voltage without heatsinks, relying on server chassis airflow for thermal management. Systems that cannot supply registered DIMM power sequencing or lack ECC support will not benefit from these features.

Six-module kit simplifies full-population upgrades

The package delivers six matched 64 GB modules in a single kit, eliminating the need to source individual DIMMs and reducing the risk of mixing revision codes. Population order must follow the motherboard manual to ensure correct channel interleaving and maximum bandwidth. No additional software, cables or cooling accessories are included. Administrators who require factory-matched sets for warranty validation or audit trails gain a single part number to track.
