I bought a motherboard a few months back that was used with bent pins but fixed they said when it came in I built my computer and the performance was amazing it overclocked my CPU to 4.5 GHz with 100 FPS avg on Rust and gta 5
Now I get errors saying my overclocked failed and then I restart and it works in games I get 60 in gta 5 locked but no v-sync on at all even turned off in the nvidia settings and 34 FPS avg on rust

PC specs:
i5-6600k @4.5GHz
12gb ram
Gtx 1060 6gb ssc
Asus z170-a - bent pins but fixed by the seller and 2/4 broke ram slots
