CPU does not want to boost

[defensie]

Hello. First of all, yes I have pbo enabled, yes its on +200, and no im not overheating.

 

My CPU does not want to boost in any high usage workload (p95, r23, even games) it reaches about 4,2ghz, whichs is 0,6ghz less than it SHOULD boost, and most of the times it even caps at 4ghz. However, when not doing anything cpu heavy, like sitting on desktop, it boosts up to 4,6 ghz, doesn't really make sense to me.

I run a Ryzen 7 5700x on a B550 Aorus Elite V2 with a Cooler Master Ml240L v2 Liquid Cooler.

For all-core loads, your CPU is going to boost less than for lightly threaded loads. This has been the norm since Intel introduced Turbo Boost 15 years ago. You only get the max boost when 1 or 2 cores are in use.

Sounds to me like it is operating properly. I have a 5900x and it boosts for short period of time to 4950GHZ but overal hangs anywhere around 3.6 on normal everyday tasks. Cinebench 23 my scores on all  cores average are 22702 and it sits at 100% unilization but its speed over all cores is rock steady on 4.5ghz with zero fluctuations.

I also undervolted my CPU as the power savings to perfomane are just so good.

Yea, well mine dont even get to 4,5 running cinebench, and the air out of my exhaust fans is ice cold haha. Only hits 4ghz steadily and hangs around 50 degrees, but outside of cinebench it idles at 4,2...

before i tweaked my system i was hitting higher clock speeds on idle but in real workloads the performance was about the same.

your first screen shot shows that it hits 4.8 in cinebench but settles in at 4.1 which is quite normal. cinebench will uitlize the CPUs efficiency for workloads not just balls to the wall speed test scenario. too often people see it as a speed test but it is a test of its efficiency for rendering. it is designed specifically for a user to gauge what suits their needs in a work environment.

your temps are good that it settles in across the cores at a stable speed is good if you thnk your idle speeds are high then tweak the performance with undervolt for example. At the end of the day your CPU the 5700x looks to me like it is performing very well compared to mine which is a 5900x. 

Also you must consider that the reading of idle speeds are often the AIDA64 as an example showing a single core boost not an all core boost which is totaly different. So you need to look at where the idle speeds appear to look higer than the worload speeds.

And finally lots of little factors to consider. is windows set to performance mode that tries to leverage best speeds and is maybe to daft to see if you are under basic workloads or pushing the system on a heavy render for example.Has the motherboard got settings that influence the CPU behavior that has been overlooked ? I still think your CPU is performing fine looking at the info in HWinfo sensor panel screenshots.
