So...for personal reasons I've been working with AMD's (terrible) API on interfacing with their cards. So far I've gotten down to using their C++ example to throw over into C# for GUI reasons. I've accomplished reading everything (crudely...) and setting fan speeds+target temp and I'm down to the last part of dev'ing the clock+voltage "set" button out. After this, it'll be a complete WattTool with the exception of VRM modifications (which I doubt I could do, even if I had the datasheet for every I2C out there) but at least it SHOULD support the 500 series.
What I'm wondering is if there's any users out there who would use this tool over WattMan? If so, I'll upload the executable (I'm going to obscure it, so it's up to you whether you want to use it or not) and possibly Github the source (I have no issues with people looking at my source; I do have an issue with people "stealing" it).
Why this? I hated WattMan since the first day it came out. It's slow, it's clunky and it doesn't let you save profiles. Utterly useless as an OC tool. WattTool was an excellent solution to this, but it has become obsolete with the 500 series cards, and the dev seems to be MIA...so...why not?
EDIT: Excuse the terrible object names in the screenshot of Visual Studio behind the tool...I was rushing it between my 9am-5pm duties. I swear I'll properly name each and every XAML field in the final build!
