Hi there, hello.
I just became owner of a Strix X670E-E Gaming. Using Ryzen 9 7950x3d.
Thinking about chipset drivers, I see that Armoury Crate offers 5.03.24.2328. But AMD itself offers
AMD gives their partners access to non-public drivers. Given the lack of a comprehensive set of release notes, we have to assume that ASUS decided that there were features in 5.03 which were worth releasing it for their boards. Use the ASUS version when it's newer, unless you have a really good reason to use AMD's older public release, as it may well have something which is important for your ASUS board / BIOS. I really wish ASUS would do proper comprehensive release notes on everything, but c'est la vie.
Ryzen Energy Plan (or was it Ryzen Power Plan, I can't remember) hasn't been a thing in the Windows power options since 3000 series (maybe also 4000 series). It went away with 5000 series, being rolled into the standard balanced and high performance plans; just install the full AMD chipset drivers package and use the standard power plans.
