AMD laptop APU usage

[stereo839]

While I am playing for example Battlefield 3 my CPU usage is only 45% and clockrate is about 1,7Ghz in Task Manager, but in MSI Afterburner is everything on 100%, is this normal?
next example:
1. Opened Chrome with few tabs(YT,FB...), hearthstone and CPU usage is 1.4Ghz a usage 55%..
2. OBS streaming just Hearthstone and open Chrome is CPU usage 60% and 1.7Ghz usage but OBS is saying something like "Check settings, frames encoding takes long time..."

The main problem: While I am doing some of this things I cant do anything because everything is laggy(ex. if I open next tab and open some site it stuck in homepage of browser and nothing happening, low frames in games, droping frames in OBS...)

1.4 - 1.7 GHz is well below the base frequency for this CPU. Is this happening with the charger plugged in? Or on battery power?

Plugged in.

If the laptop isn't overheating, then this could be a voltage issue. The CPU should run at 2.5-ish when not a lot of stress is put on it, and closer to 3.5 Ghz under heavy load.

Check your temps with software (HWiNFO64 or HWMonitor). If it's running hot (90 C +) when doing a lot of work, the laptop needs cleaned out and/or the thermal compound needs replaced.

If that's not it, it could electrical related (possibly hardware defect).

Voltage is OK, temperature I think I cant check because in both programs temperatures were about 140C and in AMD Overdriver -25C. I decided to update all drivers from AMD and now its better.

140 C is way overkill. Usually a system will shut down once a component reaches around 100 C (and -25 C never happens).

Glad the driver update helped.
