As a long time passive thread reader, I've just registered to share interesting information with you regarding S3 standby on renoir:
As known, neither on A300 nor X300 standby (ACPI S3) does work/is available when a Ryzen 4XXXG (Renoir) is installed.
Many users had the assumption that this is due to the PRO cpu. Me too, as AMD explicitely states on their website that standby is disabled by default on PRO cpus for security features.
However, other users confirmed that on other motherboards standby is working well, also with Renoir PRO cpus.
I had the chance to get a NON-PRO Renoir 4300GE. So i checked out this thesis with an interesting (and depressing!) result: S3 does still NOT work (is unavailable, see screenshot below:
Conclusion: The unavailable standby has nothing to do with the PRO cpus, but with Renoir in general!
Therefore, I'm really angry: with respect, ASRock gives a f*** about their customers!!! Non working standby on renoir still not fixed, not even on X300 (which officially supports Renoir). Ridiculous how such basic feature is "not available"!!!
PS: Coil-whine - also never fixed!
PPS: Some users would call it scam that they sell the X300 which is basically the same as the A300 (mainboard with sticker).
