When I got my Cpu I overclocked to 3,8ghz base speed and didn’t have pbo turned on idk why then I overclocked my r5 3600 to 4ghz manually in ryzen master but heard some guy say it’s better to oc on default cpu settings in bios and to reset oc before changing anything in bios. Put default settings it lagged a lot when stress tested and constant 4.1ghz 1.35 volts. Reset bios to default but turned off any oc options pc ran ok but +12voltage is at 9.8 max in hwmonitor and in bios it’s 10.3v. Also system interrupts is draining 5-10% cpu usage when it used max 1% before. And core 0 is at a constant 90% usage 1.35-1.4v when idling. When stress tested core voltage goes to 1.25 how do I fix and is it bad for my pc?
