That's exactly the same RAM I'm looking at on Amazon. I wonder if the 5600 speed (if the Asus Tuf actually recognizes it properly) is enough to overcome the CAS 46.
EDIT: I ended up ordering the 32GB Kingston Fury RAM. 5600 and CL40. https://www.amazon.com/gp/product/B0BRTJ4Q94/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
