How high is max Vcore? Most boards set a unreasonably high limit even without unlocking anything (like 1.6V for my board, I know some can do even 1.8V) which kills CPUs.

It didn’t tell me how much, there only was a +0,68V I think

 

Edit: +0,68V was the highest

So, I wanted to overclock my CPU and experimented around in the bios (my first CPU overclock btw.) and I cranked the CPU  Vcore to the max because it didn’t work before (I got an boot fail) . Then I reseted the cmos (I put the battery out and waited 10 mins) now my PC is starting and my mouse and keyboard are lighting up (didn’t happen before the reset) but my monitor shows black (it gets a signal). I don’t think it doesn't boots in Windows because when I press the shutdown button it’s off almost instantly. Pls help and tell me if u need the specs

Your probably fried your CPU from maxing out the VCORE voltage. That's is literally the one thing you do not want to do that too, and if you did any kinda of researching on overclocking you would have been warned about cranking voltage like that.

Even though you havent mentioned what CPU you're using, you're smoked since most CPUs run 1V to 1.2V at stock. +0.68V is enough to push idle voltage way deep into unsafe territory for any CPU still worth using today

I’m using amd fx 6350. It was time for a new cpu anyway so who cares :(

Like most of them said, you most likely killed it but if you do want to see if it was some how okay, re-seat the MOB BIO's battery to see if you still have a working system. Or just trip the BIO's pins if you know which ones.  I am on the FX-8320 set to 1.3850V "STOCK" for most 8000-FX chips. Also if it does work, here's a video i recommend to get started with overclocking if you still even want to. 

 

Ty, sry I went to sleep
