  • 192 GB capacity from six 32 GB modules enables full memory population
  • DDR5 4800 PC5-38400 speed matches the board's rated memory controller frequency
  • Registered ECC design corrects single-bit errors and offloads the controller for stability
  • 1Rx4 organisation with 1.10 V CL40 timing meets the exact rank and voltage spec
  • 288-pin RDIMM form factor fits the ASRock Rack SIENAD10HM3 motherboard slots

Exact-Match Server Upgrade

This 192 GB kit delivers six 32 GB DDR5 4800 RDIMMs built to the ASRock Rack SIENAD10HM3 motherboard's exact rank, voltage and timing requirements. The modules are registered and ECC-enabled so the memory controller sees every slot at full capacity and corrects single-bit errors before they affect production workloads.

288-Pin Registered Form Factor

Each stick uses the 288-pin RDIMM layout this board demands, not a UDIMM or SODIMM alternative, and carries no heat spreader to keep the profile low for dense server chassis. The registered architecture buffers the command bus, allowing all six slots to be populated without signal degradation while the 1.1 V operating voltage matches the platform spec.

Thermals, Noise and Power Draw

Running at 1.1 V across 192 GB keeps per-module power draw low, so standard server airflow handles cooling without extra fan speed or audible noise. ECC and registered buffering add virtually no latency overhead, letting the kit sustain its rated CL40 timing continuously in typical multi-threaded server workloads.

Questions about this item

What DDR5 speed and data-rate does this 192GB kit run at?

The modules operate at DDR5-4800 with a PC5-38400 data-rate, the exact speed the ASRock Rack SIENAD10HM3 memory controller is designed for.

What physical slot and form factor do these 32GB modules require?

Each module is a 288-pin Registered RDIMM, the only form factor the SIENAD10HM3 motherboard accepts; UDIMMs or SODIMMs will not fit.

In which order should the six RDIMMs be installed on this board?

Follow the motherboard manual's DIMM-population sequence for 1Rx4 Registered ECC modules; populating slots out of order is the most common reason the full 192GB is not recognised.
