System-Specific DDR5 RDIMM for ASRock Rack

This 32GB DDR5 module is built for the ASRock Rack GENOAD12M3-2Q motherboard. It delivers registered ECC operation at the exact voltage and timing the board expects so every slot runs at full capacity without manual tuning. The 1Rx4 organization and 288-pin RDIMM form factor match the platform's population rules precisely.

Who this suits and who should look elsewhere

Server builders who need a verified, single-module upgrade for this exact ASRock Rack platform will benefit from the guaranteed fitment and lifetime support. Buyers who want more storage, non-ECC consumer memory, UDIMM or SODIMM form factors, or modules for a different motherboard model should look elsewhere.

The specification that decides compatibility

The DDR5 4800 speed with CL40 latency at 1.1V in a registered 1Rx4 288-pin package is the single specification that determines whether this module will be recognized and run at its rated settings on the target motherboard.

Questions about this item

Does the 1.1 V operating voltage stay within spec when the module runs continuously at 4800 MT/s?

The module is rated at 1.10 V, matching the DDR5 standard voltage for 4800 MT/s operation, so it remains within specification under sustained load.

How much heat does the bare 288-pin RDIMM produce when fully populated in a server chassis all day?

Without a heat spreader the DRAM relies on chassis airflow; registered buffering reduces electrical load on the memory controller, helping keep thermals manageable in typical server cooling.

What motherboard feature must already be present for this 1Rx4 registered ECC module to function?

The board must provide DDR5 RDIMM slots that support registered ECC memory and the specific population rules for the ASRock Rack GENOAD12M3-2Q.
