  • Massive 768 GB capacity from eight 96 GB modules for memory-intensive workloads
  • DDR5 4800 speed with CL40 latency delivers high throughput for server applications
  • Registered ECC architecture ensures data integrity and stability under full population
  • 1 V operation reduces power draw across all populated DIMM slots
  • Verified compatibility with ASRock Rack SIENAD10HM3 motherboard for guaranteed fitment

Exact-match server upgrade

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.

Check your configuration

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.

Thermals noise and power

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.

Questions about this item

Does the 768GB kit arrive as eight 96GB RDIMMs or do I need to buy extra modules?

The kit contains eight 96GB DDR5 RDIMMs for a total of 768GB; nothing else is required to reach that capacity.

Should I choose this CL40 4800MHz kit or a different speed for the ASRock Rack SIENAD10HM3?

This kit matches the board's DDR5 4800 PC5-38400 specification with CL40 timing, 1.1V voltage and 2Rx4 registered ECC — the exact profile the motherboard expects.

What does the 4800MHz rating mean once the modules are installed in the server?

The memory controller will recognise each 288-pin RDIMM at DDR5 4800 speed, delivering PC5-38400 bandwidth with ECC error correction across all eight slots.
