So begin the actual overclock process by increasing your CPU multiplier by .5x increments at stock voltage. Test the viability of the change by running a 20 minute Prime95 blend test after each .5x increase with HWMonitor always open on the desktop to monitor max core temps. When you first fail the 20 minute stress test, go into bios and increase the CPU core voltage by one small increment and retest. If you still fail, add a bit more core voltage. Repeat this cycle until your core temps reach 55 C., the "wall". Report back at that time with pics of CPU- z and your last run of HWMonitor. Then we will give you more instructions about tweaks. In the end you will be running two hour or more Prime95 stress tests to confirm stability and make any final necessary adjustments.
Bed time for me.
