Zotac CA621 /AMD RYZEN 3 3200U TURBO BOOST

yanakis

Hi everyone.
I just got installed 2.6.0 on Zotac Zbox Nano CA621 and working quite well, stable overall.

This cpu has a boost clock of 3.5 Ghz but pfsense sees as 1400-2600 Mhz. PowerD active, amdtemp running and showing correct temps.

Any advice would be great!
Many thanks!

There's a good chance it's working anyway but just not showing.
If it isn't though powerd would need a driver to be able to enable it.

Try running: sysctl -a | grep freq and look for available frequency levels.

@stephenw10 Thanks! here is the output:

Hmm, after looking into this I'm not sure there is a driver for this. It just works and isn't shown.
For example: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249889

@stephenw10 using stress-ng and going for 100% cpu usage, the current cpu freq (sysctl dev.cpu.0.freq) was 2600 :(.

So no turbo boost at all.

stephenw10

Well, it shows that in the returned frequency but if you read through that bug report that is probably never going to show the turbo frequency because it's not a p-state.

Intel CPUs show similarly though they usually use a +1 to indicate turbo is active. For example:

[2.6.0-RELEASE][root@xtm800.stevew.lan]/root: sysctl dev.cpu.0
dev.cpu.0.temperature: 36.0C
dev.cpu.0.coretemp.throttle_log: 0
dev.cpu.0.coretemp.tjmax: 105.0C
dev.cpu.0.coretemp.resolution: 1
dev.cpu.0.coretemp.delta: 69
dev.cpu.0.cx_method: C1/mwait/hwc C2/mwait/hwc
dev.cpu.0.cx_usage_counters: 68133 0
dev.cpu.0.cx_usage: 100.00% 0.00% last 265us
dev.cpu.0.cx_lowest: C1
dev.cpu.0.cx_supported: C1/1/1 C2/2/59
dev.cpu.0.freq_levels: 3201/77000 3200/77000 3100/73079 3000/69986 2900/66950 2700/61045 2600/58188 2500/55374 2400/52614 2300/49215 2200/46570 2100/43989 1900/38963 1800/36528 1700/34144 1600/31811
dev.cpu.0.freq: 3201
dev.cpu.0.%parent: acpi0
dev.cpu.0.%pnpinfo: _HID=none _UID=0 _CID=none
dev.cpu.0.%location: handle=\_PR_.CPU0
dev.cpu.0.%driver: cpu
dev.cpu.0.%desc: ACPI CPU

3201 indicates turbo is active but that can be variable depending on how many cores are used. That particular CPU can go to 3.6GHz on 1 or 2 cores.

@stephenw10 said in Zotac CA621 /AMD RYZEN 3 3200U TURBO BOOST:

sysctl dev.cpu.0

So we don't know for sure which is a bit frustrating when using AMD, I guess Intel gets the goodies always. Could be a bios thing or is just freebsd?

Anyway, many thanks for you time, appreciated!

It's probably just lack of driver support in FreeBSD. It will likely come at some point.

@stephenw10 most probably. I booted a windows 11 instance and benchmarked the cpu, It went easily over 3 Ghz mark. On idle went below 1.4Ghz. So there it is.

I saw on some thread I lost, there are some amd specific modules, I need to look into it.
