AMD Ryzen 3 2300U | Is 3.4GHz but says 2.0GHz.

Hi! =)

According to this page:
https://www.amd.com/en/products/apu/amd-ryzen-3-2300u

My CPU max frequency should be 3,4GHz. (boosted)
But in various output commands always says 2.0GHz Max.

Im think I losing 1,4GHz of processing power, how can I solve this?

plug the laptop into mains electric and try again, also may not be possible without some coding, anyhow use the benchmarks mentioned in this blog to find out exactly what is going on with your apu:

It's already plugged, always is plugged.

Its secure to put this in "src/mainboard/pcengines/apu2/OemCustomize.c" ?:

VOID
OemCustomizeInitEarly (
    IN  OUT AMD_EARLY_PARAMS    *InitEarly
    )
{
    InitEarly->GnbConfig.PcieComplexList = &PcieComplex;
+    InitEarly->PlatformConfig.CStateMode = CStateModeC6;
+    InitEarly->PlatformConfig.CpbMode = CpbModeAuto;
}

I don't even have the folder mentioned there ...

no, don't start messing with anything, just try the benchmarks and see what happens. the single core boost should happen within thermal allowance even if your system reports only 2.0GHz in the utilities you are using to try and detect 3.4GHz being recognised by the system.

Ok, doing the first test in the blog.
I will posting results in a minute.

#7

fine, i'm off to bed so happy hunting. also try phoronix test suite and compare it to the existing results for your system someone's already posted from Fedora 31.

Night night! Thanks for helping.

Also, bad news for me I think.
In a Fedora 31 Benchmark says that this CPU have 2.0GHz too, a benchmark comparison will be useless maybe...

please post the output of 'systemctl status cpupower.service ' . Is the service disabled ?
if the service is not active please use 'sudo systemctl enable cpupower.service' and then 'sudo systemctl start cpupower.service'. after this recheck the status, but the problem should be solved after this. please reboot and confirm that everything is ok after rebooting.

Hi olli!
Well, it was actually diseabled!
I going to reboot and see what happens.

GHz

Don't work, the cores keep running at 2.0GHz.
(same for a single core.)

#13

you're on the right way, now let's see what settings are avaiable with 'cpupower frequency-info'
post the output.
with 'sudo cpupower frequency-set -g performance' you'll set it up to max. with 'sudo cpupower frequency-set -g powersave' you'll redirect to energy safing mode.

Before

[admin@inspiron3585 ~]$ cpupower frequency-info
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 1.60 GHz - 2.00 GHz
  available frequency steps:  2.00 GHz, 1.70 GHz, 1.60 GHz
  available cpufreq governors: performance schedutil
  current policy: frequency should be within 1.60 GHz and 2.00 GHz.
                  The governor "schedutil" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 1.43 GHz (asserted by call to kernel)
  boost state support:
    Supported: no
    Active: no

Then (with 'sudo cpupower frequency-set -g performance')

  boost state support:

    Active: no

Now I see that it says 2.58Ghz! That's good!

#15

open a terminal, use 'watch grep "cpu MHz" /proc/cpuinfo' to check the speed periodical, open some powerconsumpting software and you'll see that it will boost to max. that should be fixed now.

Yes, the cores now reach 3.0GHz and beyond.
Problem Solved, thank you so much.
