System-Specific DDR5 Kit for ASRock Z790 PG Sonic

This 64 GB kit contains two 32 GB DDR5 UDIMMs built for the ASRock Z790 PG Sonic motherboard. It targets builders and upgraders who need a validated, plug-and-play memory solution for that specific board.

64 GB capacity at DDR5 5600 CL46

The two modules deliver 64 GB total at 5600 MT/s with CL46 latency and 1.10 V operation. That headroom suits heavy multitasking, content creation and gaming workloads; systems requiring ECC, registered DIMMs or speeds above 5600 MT/s will need a different kit.

288-pin DDR5 UDIMM, non-ECC, unbuffered, 1.10 V

The decisive specification is the 288-pin DDR5 UDIMM form factor with non-ECC, unbuffered signalling at 1.10 V. Only motherboards that accept this exact electrical and physical interface can use the kit.

Questions about this item

Will the 5600 CL46 kit run with the 4800 DDR5 modules I already have installed?

The kit is rated at 5600 MT/s with CL46 at 1.10 V; when mixed with slower DDR5 the system will typically downclock all modules to the lowest common speed and loosest timings.

How can I verify the 64 GB kit is operating at 5600 MT/s after installation?

Open the BIOS or a tool such as CPU-Z and confirm the memory frequency reads 5600 MT/s (PC5-44800) with timings of CL46 at 1.10 V.

Does the package contain only the two 32 GB UDIMMs or are any cables or brackets included?

The box includes the 64 GB (2 × 32 GB) 288-pin DDR5 UDIMM kit and nothing else; no cables, brackets or additional accessories are supplied.
