I'm currently using a stock cooler, I will receive my hyper 212 evo soon, and I want to overclock my i5 to 4.00Ghz exactly. I'm a bit of an amateur when it comes to overclocking, do you guys know which settings I should use?

Here are my specs:

Intel Core i5 2500k 3.3 Ghz
ASRock Extreme3 Gen3 Z68
Nvidia Geforce PNY XLR8 GTX 460 OC
8GB (2 x 4GB) 1600 Mhz Corsair Vengeance Blue
Ultra LSP650 650W

Settings-------
Advanced Turbo 50:
Load Optimized CPU OC Setting:

CPU Control------
CPU Ratio Setting:
Internal PLL Overvoltage:
Intel Speedstep Technology:
Intel Turbo Boost Technology:
Turbo Boost Power Limit:
Additional Turbo Voltage:
Core Current Limit:
Host Clock Override (BCLK):
Spread Spectrum:

Voltage Control------
Power Saving Mode:
CPU Core Voltage:
CPU Load-Line Calibration:
DRAM Voltage:
PCH Voltage:
CPU PLL Voltage:
VTT Voltage:
VCCSA Voltage:

Then there are CPU Fan settings and some other stuff. Thanks for your help! If there is any additional settings that will increase my performance on a ASRock E3 G3 Motherboard let me know :D

Use the BIOS or AXTU to OC if you are a newbie. You can go into the settings on the AXTU and set a 4.0 OC , but you may have to reboot after you reset.

BTW the AXTU settings are factory tested by ASRock.

Ok. I have the same mobo and CPU as you, and this is a 4.5ghz setting 100% stable.
Of course, if you so desire 4.0ghz, you should be able to leave everything at Default, and just change the CPU multiplier

CPU Multiplier x45
BCLK: 100mhz
Short and Long duration: 230/200.
core current limit 200
Vcore: OFFSET mode +0.020Volts
Load line calibration: LEVEL 4
Spread spectrum disabled
SpeedStep: on

Everything else leave auto.

max temps i get is 58C...H80 cooler. With a 212 expect like mid 60s

Everyone has a different 2500k, so test the voltage first. You might need higher or lower, but this is what worked successfully for me.
