asus pn50 and cpufreq/boost

I’ve been using an ASUS PN50 (that’s a mini pc, with an AMD Ryzen 4800u processor – so sort of a laptop without a screen) as my desktop for ages.

Increasingly I’ve found it sluggish and I was contemplating replacing it with something newer, and then I discovered why the CPU speed in /proc/cpuinfo was always 1400mhz….

I needed to :

echo 1 > /sys/devices/system/cpu/cpufreq/boost

Once that’s done, the CPU cores can go up to about 4.2Ghz … #doh

In other news – looks interesting.

Unfortunately now my minipc’s fan is always speeding up / slowing down when it used to be pretty quiet :-/

Thanks to
