Hi, I have a fx-6300 and I'm trying to overclock it on a Gigabyte 78lmt-usb3 mobo. I know it's a bad idea and it's a bad mobo but I still want to try, I have a Gammaxx 400 CPU cooler and on full 100% load and 3.8 GHz im at 33 degrees Celsius. On AMD overdrive whenever I turn the multiplier for 17.5 to 18 it instantly turns off my PC. Help pls
