It should be on by default, but it doesn't hurt to check either way. If you want to enjoy significantly better performance in any app or game, make sure that you enable Precision Boost. This comparison has proven that the Precision Boost feature is not a marketing gimmick. I was checking my CPU frequency with cpupower frequency-info:Ĭurrent CPU frequency: 1.Maximum CPU frequency (single-core): Precision Boost enabled, Precision Boost disabled Precision Boost has a significant positive impact on the performance of AMD Ryzen processors Anyway, I found the problem, it was my approach. I would be happy if some Linux driver developer would take a look and say what is wrong with my approach or provide documentation for open source driver team if Linux kernel is broken at this point:ĪMD responded my distribution is not supported. Yeah, of course, I could use Catalyst driver, but it's so outdated that it wouldn't work anyway. My CPU is supposed to go up to 3,8GHz with Turbo Core technology but all I get is 3,1GHz because it seems that something is not properly initialized by radeon driver. I really didn't expect that my CPU clock frequency will be lowered just because I'm using Linux. I bought your CPU AMD A8 7600 (AD7600YBJABOX), my motherboard is Asrock A88M-G/3.1. I tried with 1, 2 and 3 threads but unfortunately 3,1GHz is the ultimate barrier I came to the conclusion that CPU needs to have some free power to "boost" frequency, so I tried with less threads stressing the CPU. I must have done something wrong yesterday. cpupower frequency-info doesn't show 2,4GHz but 3,1GHz. Truely, I have such a limit set, as it can be seen in this file:
I read further and I found information about BIOS limits ( … clnk&gl=pl). I tested it with mprime torture test and frequency reported by cpupower frequency-info never exceeds 3,1Ghz.
