My r7 1700 uses only 1 cpu while gaming, maxing it out. it happens almost on every game - rocket league, overwatch etc.
This causes huge fps drops (from 200+ to 120 out of the blue), stuttering (which is my main problem).
Latest GPU drivers (gtx 1080), latest bios (Gygabyte ab-350gaming 3 f51)
My cpu is OC'd to 3.8ghz 1.32v (as of rn)
corsair vengeance 2x8 2666 oc
if any other information is required please let me know
thanks!
edit: also, is this normal? https://prnt.sc/uon259

Were the games in question installed and running from an earlier installation with earlier different hardware, perhaps?

Often configuration is done at a game's installation, and although it may appear the OS is doing fine with new hardware/driver updates without a nuke and pave, perhaps the game must be removed/reinstalled from scratch.

CPU-Z score is right for that frequency but I'm not sure why are games running on one core. Do you have latest chipset drivers ?

I do. chipset 606 19.10.16, as on the motherboard's website.
I've seen CPU-Z scores around 15k for that frequency... Is it possible?
example:

edit: another example
https://community.amd.com/thread/214319
That was an old version of CPU-Z and it's benchmark. On latest one (19.01.64 beta) my 3700x scores 1860 and on standard 17.01.64 b4nchmark scores 5678/529.
You may want to try with Cinebench R20, it shows number of threads used as it runs. Score is not that important at the moment.

...
The '19.10.16' could mean it was released in late 2019. That would be way out of date, but then mfr's often don't keep things as up-to-date as they should with deprecated product so not unexpected. Do yourself a favor and go get the latest from AMD's support site. They were released in July of 2020.

When you install the chipset drivers it will install an AMD power plan...the Ryzen Balanced power plan. Run that plan and do not make changes to it.

Also check that your BIOS is up to date as early BIOS rev's on B350 and 1st gen, in particular, were very bad for memory support in particular. Be sure to reset CMOS after updating BIOS.
