r5 3600 stuck in all core boost

[Whagwan]

Hi all,

I'm at a bit of a loss at to why my r5 3600 is sat in all core boost at ~4.0Ghz in idle and under load.

M/board is the MSI B450 tomahawk max. I have the latest chipset drivers and windows version, Power plan is set to Ryzen balanced.

I've tried lots of options as to turning on/off PBO, overclocking in both bios and Ryzen master, clearing CMOS to reset BIOS settings to stock etc.

Whatever I do it always sits with all cores boosted at the same speed. If I run prime 95 or load the CPU speed drops slightly, if I try and run a single thread test in CPU mark all cores continue to sit at the same speed.

Any help much appreciated!

Doesn't look like anything unusual running to load the CPU, and as you said, temps are cool and so is power. When I run P95 or Folding@home, power draw, temps and fans rise.

Open VPN @ 3.5% wouldn't be enough to keep the CPU in boost surely?

All seems a lot lower now for some reason, with utorrent still running. Still showing 99% utilisation though, any ideas whats going on here? I'm stumped...

Only firefox tabs open last night were Twitter, facebook, gmail, overclockers and tom's hardware so nothing too dodgy there?

Ran a deep malware scan, killed firefox and torrents and CPU is still running on all-clock boost.

I ran CPUmark and am getting an average score for the r5 3600 so not concerned about whatever it is taking too much CPU power, so for now I've set just set a manual OC with Voltage of 1.3V and all-core boost of 4.1GHZ
