Hi Michael,
Do you know if there are chipsets on both sides of your DDR5 or not?
Sorry that we could not find the PCB photo of your DDR5 ram.
If your DDR5 RAM only one side has the chipsets, our water block Bitspower 4-DIMMS RAM Water Cooling Module (DDR5, Single-sided) is compatible.
If both sides have chipsets, you can choose BP-RAMS44D-D5.
Or you can send us photos of both sides of the PCB. We will check and reply to you.

2. Motherboard - ASUS Z790 Hero is compatible with 4 pcs of DDR5 RAMs.
