Your call: hype or real?
Real = it will matter in daily use. Hype = louder than it is. One vote, and it can’t be changed.

Why it matters
Linux users have no official tool like Ryzen Master on Windows, and this is a first step toward one.
Watch: Linux support keeps improving.
The details
- An AMD engineer, Shyam Sundar S K, submitted patches for the AMD Overclocking Driver to the Linux kernel.
- It connects Linux to the processor firmware and exposes controls through the sysfs interface.
- It adjusts three limits, PPT, TDC and EDC, and reads the allowed ranges and current memory speed.
- It can switch SMT on or off at firmware level, and changing the three limits needs a reboot.
- It exposes only a small part of AMD's options, does not replace Ryzen Master, and kernel inclusion is not yet confirmed.
