Gupsterg a user on here and OCN had same memory kit same motherboard and x2 1700's 1 could do 2933 the other could do 3200.
Plenty of users on the same bios same ram kit are getting mixed results.
Yeah can link several user experience where they change CPU and gain higher RAM. Fugger, has extreme cooling as well, OC experience. Then you got other members like Chew who are hitting 3200MHz with dual rank ram.
1TM1 has 1800X Hynix M used same setup on C6H + Asus Prime X370 Prime 3200MHz, 1700X 2993MHz. Disasterpiec99 1700 3200MHz, 1700X 2933MHz, same board/ram. There was a post on the OCN owners thread where I also linked lots of posts, older UEFI on C6H have 3200MHz, newer not. Then you have other members hitting 3200MHz regardless of UEFI versions. Recently this member on TPU, stuck at 2133MHz and states seen others with same board/RAM have 2400MHz.
All in all mixed bag.
