never used refind here on real hardware and over longer time… still on systemd-boot
I got it finally.

Edit: This looks different now?

yes only two governors now…
I’m having a hard time deciphering the difference? Except frequency is higher now?
Edit: I changed from all core to per clock cycle and it jumps up.

Interesting, where do I find if it is ZNVER3 or MZEN3 based?
CPU:
Info: 8-core model: AMD Ryzen 7 5800H with Radeon Graphics bits: 64
type: MT MCP cache: L2: 4 MiB
Speed (MHz): avg: 2780 min/max: 400/4463 cores: 1: 3169 2: 2767 3: 3169
4: 3169 5: 2533 6: 2535 7: 2628 8: 2986 9: 2535 10: 2534 11: 2534 12: 2533
13: 2532 14: 2533 15: 3169 16: 3168
I add the repo to pacman.conf and then used akm kernel manager to install the amd kernel and headers.
Edit: Not sure if that is what you are asking?
ZNVER2 or ZEN3 should be the question?
I think so as it confused me?
Edit: Btw zen4 is out! Almost!
Copied and pasted:
linuxkernels/linux-amd 5.18.v.9-1 (82.6 MiB 144.9 MiB)
Linux kernel aimed at the latest AMD Ryzen CPU based hardware (ZNVER3/MZEN3)
Zen3 is only 5000 series correct? So Linux amd kernel on my 3800x is not really tuned for it?
amd namings and versions are very confusing i think
I don’t know but mine is listed under performance cpu in the list for the 3000 series anyway.
Yes… I need a zen3 or i wait for zen4
yea also a solution to the problem
It’s not really a problem…this cpu holds it’s own.
Thanks guys, installed linux-amd and all is well, but cannot see any noticeable difference (yet). Was running linux-zen which did feel snappier (compared to ‘linux’).
yes same for me only try out to see if it is causing difference… i see it is faster on building packages compiling and stuff but you will not see this on normal usage…
I am more interested in powersaving and silent fans … what was snot possible to set without loading these two modules on my hardware the amd-kernel was only to play
Compiled emacs-git (with my flags) :
took 1m 28s ➜
Will reboot to linux-zen and try it later
