128GB DDR5 Kit for ASRock Z790 Riptide

This 128GB kit contains four 32GB DDR5 UDIMM modules rated at 5600MHz with CL46 latency. It is built specifically for the ASRock Z790 Riptide WiFi motherboard using unbuffered non-ECC memory. The kit targets users who need maximum supported capacity on this platform.

Check DDR5 Slot Count and CPU Support

Verify your motherboard has four DDR5 slots and that your installed processor supports 128GB total capacity at 5600MHz. The modules require 1.10V operating voltage and fit standard 288-pin DDR5 sockets. Confirm the board accepts 2Rx8 dual-rank modules before ordering.

Four Modules Fill Every Slot

Populating all four slots delivers the full 128GB capacity without leaving empty sockets for future expansion. The dual-rank 2Rx8 organisation works with the memory controller at the rated PC5-44800 speed. No heat spreaders are fitted so clearance for large CPU coolers remains unrestricted.

Questions about this item

Does the kit include all four 32 GB modules or must any be purchased separately?

The package contains the full 128 GB kit — four 32 GB DDR5 5600 UDIMMs — so nothing else is required for installation.

Should I pick this 128 GB CL46 kit or a lower-capacity option for the ASRock Z790 Riptide WiFi?

Choose this 128 GB (4 x 32 GB) CL46 kit if you need maximum capacity; select a smaller kit only if 128 GB exceeds your workload requirements.

What does the 5600 MT/s rating mean once the memory is installed in the Z790 Riptide WiFi?

The modules will run at DDR5 5600 (PC5-44800) with CL46 latency at 1.10 V, delivering the rated speed and timing on this motherboard.
