Ryzen "pausing" when overclocked? (CPU-Z bug?)

I noticed this a few days ago, when I had some issues, and disabled my overclock, and then re-enabled it.

At stock speeds ("UEFI Defaults"), Windows 10 is fast and smooth, and my mouse movements are smooth.

If I set freq to 3800, voltage to 1.325V, DRAM to XMP Profile 1, DRAM speed to 2400, and disabled "Global C-States" (a Ryzen overclocking recommendation from another user early on), and then boot Windows 10 - I get mouse lag.

Like, I can move the mouse, and there's a slight delay, and when I circle the mouse, it moves smoothly, then lags, then moves smoothly, then lags. It's the weirdest thing.

And I thought that last time I had it overclocked to 3.80Ghz (3800 setting), that I didn't have any of these issues.

I do have an RX 570 4GB XFX video card, running 17.7.2 drivers, of which I had to roll back and re-install those, rather than the newest Crimson drivers, because my Start Menu and Notification Menu weren't coming up when clicking on them, after upgrading Windows 10 to 1709.

I think that I may have noticed this on another Intel rig too, when I was running the newest CPU-Z. Can anyone try out the newest CPU-Z, and leave it running, on either a Ryzen or a G4560 / G4600 CPU, and see if you get occasional "mouse lags", when circling the mouse?

If this is a hardware issue, that would really bother me, but I think that it's mostly a software thing, though I haven't been able to fully track it down.

Edit: I just ran CPU-Z 1.81.1 x64, with my Ryzen R5 1600 at stock, while Mining with NiceHash in the background, on both the CPU and RX 570 4GB dGPU, and my mouse movements were smooth.

Edit: Ok, I rebooted, set freq to 3600, voltage to 1.325V, should be a simple and stable OC, then booted into Win10. Had some lag before opening CPU-Z, then I realized that the reboot, had triggered Windows Update. So I let that finish, reboot, and then with Skype, Task Manager, and Firefox Nightly running, the mouse circles are mostly smooth, but if I start CPU-Z 1.81.1 x64, then I get pauses, pretty-much every second or so, when I circle the mouse.

Edit: Closing CPU-Z 1.81.1 x64, and opening CPU-Z 1.80.0 x64, does the same thing, pauses every second or so when moving the mouse in circles.

Edit: Closing CPU-Z, and running CrystalDiskMark 5.2.1 x64, on my SSD, does not produce any lag in the mouse.

I'll have to check next time I boot Win 10, but I don't recall any problems. Using 1.178.1 x64 (Asus version).

Which mobo do you have, and I wonder if HPET has anything to do with what you and I are seeing on our boards.

I've got an ASRock AB350M Pro4 in this rig.

Crosshair 6 Hero. I have Process Lasso running, I didn't notice any of my cores going high and RAM usage was low (I'm running 2x16GB DDR4-2400). I have power set as balanced. I get a chance later, I'll try High Performance and Bitsum Optimized High Performance to see if there's any difference.

No issues here. Still running 3850 @ 1.375v vcore, 1.35v RAM and 1.1 SoC.

I had this too. I think it's fixed with the newest Crimson drivers now, but if not, stopping and disabling the "AMD External Events Utility" service and rebooting fixes it. Found here: https://www.reddit.com/r/Windows10/...not_working_action/?ref=share&ref_source=link

increase the voltage by 0.1.. could just be its not getting enough juice with vdroop.
