Why are the frequencies dropping to as low as 3.5ghz during a Geekbench4 benchmark run? I thought the base frequency was 3.9ghz on the 3800x?
In the video you can see the 3800x frequencies drop as low as 3.5ghz... Can anyone confirm this is how the cpu is suppose to act and react? yes I'm hitting the max boost, but the low base frequecies are questionable to me.. Default bios settings, xmp profile 1 for gskill 3600mhz royal memory, bios version 1.8, amd's latest chipset drivers, windows 10 latest updates running Ryzen balanced powerplan.. I'm also running a 280mm aio, cpu doesnt get over 35c during the benchmark run.. video of a Geekbench4 run.. https://www.youtube.com/watch?v=lur6O871cEY |

no load no base clock

That video is taken while running a geekbench 4 benchmark.. There should be some load on the cpu the entire time..

Use HWInfo instead of HWMonitor!
Make your own powerplan based on Ryzen balanced powerplan -> Performance, to see the base frequency when CPU is in idle state Make a testrun with this powerplan, one with the Ryzen balanced and compare. |

if its underload the entire time cpu utilization will be 100% in the whole test....

Setting to performance doesn't mean 100% load, just use high CPU clock even if there is 0% load. CPU also goes to idle.

i was answering his reply
performance mode only sets the min cpu perfomance to 100% speed thus negating CnQ to base clock |

not with exactly with Ryzen3000, it isnt at a full load when under load.. If that makes sense..
If I run a cinebench run it will load all cores equally, like 4.2ghz, but only one, two or sometimes even three cores will hit max boost at any various time, usually when first initializing the test, then settling to 4.2 across all cores... Running something like geekbench or 3dmark timespy or firestrike, I get wild fluctuation's like shown in the video, dipping well below the advertised base frequency.. I cant believe no one hasnt noticed this before.. This fluctuation has to reduce the cpu's overall performance. I dont feel like there is anything wrong with the cpu, as it runs within margin of other 3800x's.. But dipping as low as 3.5 ghz (400mhz below base clock) while running these various benchmarks doesnt seem right, that means it would do it while gaming also. I think it has something to do with the power delivery, either through the bios or actual power delivery of the board not reacting correctly. Like the voltage is dropping too low when its not suppose too or its dropping the voltage like its suppose to and not recovering fast enough.... I feel cpuid hwmonitor reports better than hdwareinfo, according to amd reps on their forum hwinfo was reporting wrong early on and they said to use cpuid hwmonitor, so I stuck with it and Ryzen master. |

adding to above comment..
Is there a way to core park the base frequency? |

how are you not getting this if you run something like prime95 on all cores it will never go below base clock. running geekbench firestrike or whatnot will have parts when it doesnt stress the cpu thus cnq will be in effect be it for a split sec or in between the test. CNQ & boost clocks are updated in split second
"cool and quiet" when enabled will dip the clock when the core isnt under load which is stated by Ray62 if you dont want it to dip either disable CNQ or set "processor power management> mininum processor state" to 100% under power options in windows or set it to performance as stated by ray62 |
