I recently built a new PC a few weeks ago and everything has worked out so far, however randomly throughout the day the core speed of my CPU drops extremely low. My computer could be idle, low stress like watching youtube / playing an indie game or midway during a heavy 3D render and my CPU clock speed will drop speeds for several minutes then return back to normal randomly. I'd understand if my CPU was throttling due to high temps but this is happening when I have 45c ~ 60c temps and I did high stress liquid bakes for 5 hours with no issues.
No experience of freezes or crashes. All my settings are stock in bios and I've adjusted my thermal paste twice, Could it be a hardware issue? Or something that needs to be enabled in my settings?

Secsal, what is the complaint? This is how Ryzen works. When a core has no work, it goes to sleep or very low clock. The problem is the reporting of clock speed for a multicore processor. Windows gets it wrong and even CPU-Z does not know what to do. Use Ryzen Master (RM) to see what is really going on on all cores. There are many threads here about this "problem". John.
Let me clarify then, Whenever I get these sudden Drops in clock speed my computer ceases to function and everything becomes extraordinary laggy for several minutes. This sudden drop happens randomly and abruptly even when my CPU is under heavy load working on something which I have to stop and put windows in sleep mode for a moment for a quick fix. This isn't how my 5950x nor how my 7950x worked.
Secsal, post a screenshot of RM when this is happening. John.
It took awhile for it to happen but here is a Screenshot of RMs. Top is sudden drop in performance while the bottom shot is normal performance. I took this while doing a few simple View-port renders in blender, however this also tends to happen even in low stress activities in the same duration.
Thanks, Secsal. Have to think on this. If you can get a screenshot of Task Manager Processes with maximum of the CPU column at the top while all the cores are very low clocks as showed in your top screenshot above. Thanks, John.
Here is a SS of Task manger CPU processes and performance. I've tried closing all processes when this happens but it doesn't really stop the laggy slideshow.
Secsal, this shows that there is no work assigned to Ryzen. This agrees with the RM SS and was the only thing I could think of when looking at all the cores at very low clocks. Windows is responsible for assigning task to the cores. Your processor is doing nothing because Windows assigned no tasks. Are you running a game via the Internet? Can you run a non-Internet game to see if you have the same behavior? John.
Nah no game is being ran via internet at the time of the screenshot. Just multiple tabs of youtube, a few streams and reddit threads. I've had this happen when running indie games on my my computer and when playing wow via internet.
However the conditions for the RM SS is different from the Taskmaster SS. I had blender rendering several hundred viewport frames when the slowdown occurred for the RM SS, While the Taskmaster SS I only had firefox running. If it's windows related is there something I need to enable or disable?
Thanks, Secsal. What was running when the RM SS was taken? John.
Thanks, Just a medium load blender render and firefox with roughly 26 tabs open.
Secsal, is this what you are complaining about? If not, I need to see a SS of RM and Task Manager when you see the clocks at minimum. There is nothing to consider so far, just that your processor has no tasks assigned. John.
michaljordan, I have no opinion about gbapp. I recommend you uninstall it, reboot and try again. If you still have a problem, open a new thread with all your parts and a screenshot of RM when this happens. John.
Hey I'm having the exact same issue with my 9950x, did you end up figuring out a solution?
