NEMIX RAM
Eight 96GB DDR5 RDIMMs deliver 768GB of registered ECC memory at 4800MHz with CL40 timing and 1.1V operation for the ASRock Rack SIENAD10HM3 motherboard
Size 768GB 8X96GB
This 768GB kit contains eight 96GB DDR5 4800 modules built to PC5-38400 specification. Each stick is a 288-pin registered ECC RDIMM running at 1.1V with CL40 latency and 2Rx4 organisation. The kit is validated for the ASRock Rack SIENAD10HM3 motherboard and uses major-brand Samsung, Micron or Hynix chips.
Confirm the motherboard manual for approved DIMM population order, maximum supported capacity per slot and any BIOS version requirements before ordering. The registered RDIMM form factor is mandatory; unbuffered UDIMM or SODIMM modules will not work in this platform. Verify that all eight slots can be populated simultaneously at the rated speed.
Modules operate at the standard DDR5 1.1V level with no integrated heat spreader, so airflow across the DIMM area is required for thermal management. Registered buffering reduces electrical load on the memory controller when fully populated. Power draw scales with all eight ranks active; ensure the server chassis provides adequate cooling for sustained workloads.
