I have a G3258 CPU, currently at 4.1 ghz. Im curious if i could increase it more, without harming my pc. For a runt like me, the temps seem to be good still. I never changed anything on voltages, i just bumped the number 32 (default) to 41 in my Bios.
Do a OCCT to see max temps/stability and if you can cut some vcore, but I wouldn't go further than this or 4.2 on stock unless you got a golden sample or something.
