Exact-match DDR5 RDIMM kit for ASRock Rack servers

This 768GB kit contains twelve 64GB DDR5 5600 RDIMMs built to the precise 2Rx4 1.1V CL46 specification the memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors on the fly. It is intended for administrators who need full-capacity population on the ASRock Rack TURIN2D48G-2L+/500W motherboard.

Verify motherboard population rules before ordering

Consult your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps. The board requires 288-pin Registered RDIMMs, not UDIMMs or SODIMMs, and population rules differ by model. Buyers who need a different capacity, a different rank configuration, or non-ECC unbuffered modules cannot use this kit.

Sustained-load behaviour with registered ECC

Registered buffering keeps every slot stable when all twelve modules run continuously at DDR5 5600. ECC corrects single-bit errors during extended workloads, preventing silent data corruption and unplanned reboots. Modules operate at 1.1V without a heat spreader, so adequate chassis airflow is required to maintain thermal limits.

Questions about this item

Does the 768GB kit arrive as twelve 64GB modules or must I buy extra DIMMs?

The package contains twelve 64GB DDR5 RDIMMs for a total of 768GB; no additional modules are required.

Why choose the 12 x 64GB CL46 kit over a smaller capacity?

This exact-match kit fills all twelve slots on the ASRock Rack TURIN2D48G-2L+/500W motherboard with 2Rx4 registered ECC modules at 1.1V, giving the maximum supported capacity at the board's rated 5600MHz speed.

Will the CL46 timing run at 5600MHz once installed in the server?

Yes, the modules are spec-matched to the motherboard's DDR5-5600 (PC5-44800) memory controller, so the registered ECC DIMMs operate at the full 5600MHz data rate with CL46 latency.
