Hello so i have Ryzen 7 3700x and b450m plus motherboard i updated bios to newest version so it would detected the processor and it all worked fine.. i saw high temperature spikes on processor so i went to lower the voltage and i turned on some option in bios and it automaticly switched from 1.45v to 1.10v..then i changed profile in amd ryzen software to gaming profile and pc freezed.. i turned it off and back on again changed the option in bios back to how it was and the pc has black screen from then on.. any idea?

I also tried switching to ryzen 7 2700x and it worked just fine...

just reset bios, and drop in 3700X again. I personally will avoid using software to adjust. To me, there is some conflict between set profiles and the options you touched in bios. You may remove CMOS battery for 1 min and then put back, didn't see jumper.

i removed battery for around 25seconds and it didnt work.. should it be longer ? cuz its weird the ryzen 7 2700x did startup the 3700x doesnt..

if you boot with 2700X, disable the Ryzen Master. Then reset bios directly in the bios and then retry. I doubt you have broken the CPU...
there is one more thing when i was updating bios i removed the CPU cooler and the cpu stuck to the cooler and i rolled few pins abit but not too much.. i fixed it and the processor was working until that happend what i wrote above..(i suppose thats not the problem i have black screen or could it be?) only thing is i cant get 2700x in my mobo anymore cuz i dont have it was lending it from a friend.. any other thing i can do except the bios battery removal?
