The point is CPU-z & HWMonitor show fake frequencies. Everything else is good.

Why fake?
Because whenever I use MSIAfterburner in programs, it shows me that I dont know - game works at 900-1900MHz and the performance is very shit (90-150FPS at like 6 years old game at lowest settings).
So, all the other programs besides MSI afterburner are wrong? That's, extremely unlikely. MSI Afterburner hasn't like, been updated in quite a few years now.
Are you complaining about "low" CSGO FPS? There's so many other reasons for that besides a "fake" CPU. If your CPU was fake, it'd be obvious in all these other programs.
90-150 FPS isn't "bad" either, it more likely means the game can't push the CPU to work any harder.
And are you sure MSI Afterburner isn't show you the GPU clock? which can max out around 1900mhz.
Also MSI Afterburner comes bundled with a much older version of RivatunerStatistics Server (which is what the OSD actually is). It;s up to version 7.0 now:

And use HWInfo64 to add the other values to be displayed in RSS:

Turn off MSI Afterburner because it will, conflict.
