Exact-match DDR5-4800 kit for ASRock Rack

This 576 GB kit delivers six 96 GB DDR5-4800 Registered ECC RDIMMs built to the exact rank, voltage and timing the motherboard expects. It is intended for administrators who need the full supported capacity recognised at rated speed without manual tuning.

Capacity and headroom

The six modules populate every slot with 2Rx4 registered DIMMs, giving the maximum 576 GB the platform allows while ECC corrects single-bit errors on the fly. Workloads that exceed this ceiling will require a different motherboard or a higher-density platform.

Thermals, noise and power

Modules run at 1.1 V with no heat spreaders, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw low and silent in normal server operation.

Questions about this item

Will the 6x96GB DDR5 4800 RDIMM kit run at full speed alongside any existing DDR5 modules I keep in the ASRock Rack SIENAD10HM3?

The kit is rated DDR5 4800 CL40 at 1.1V with 2Rx4 registered ECC. For full-speed operation every installed DIMM must match those specifications; mixing different speeds, ranks or voltages will force the memory controller to run at the lowest common settings.

How can I verify the 576GB kit is recognised correctly after installation in the SIENAD10HM3?

Power on the server and check the BIOS memory summary or the operating system memory report; both should show 576GB total across six slots at DDR5 4800 with ECC active.

What does the MR38400-9624K6 package contain and is anything else required?

The box includes six 96GB 288-pin DDR5 4800 ECC registered RDIMM modules; no additional hardware or accessories are needed for installation.
