Absolutely possible. That bios looks very much like the same as a ga-z68-ud3h I used for a bit, and I found it cumbersome to overclock compared to other boards. Can you find any kind of Load Line Calibration (LLC)? If so, try a mid range setting, set frequency to 4.2, vcore to manual at 1.25v, then run prime95 keeping an eye on temps and see if you have any failures. 24 hours of prime will verify a rock solid overclock. If it fails, bump voltage up a little (1.28 for instance). Watch temperatures! Although you can let the cpu run as hot as 90C+, most people like to keep temps in the high 60's, or low 70's to help prevent degradation.
Just point, and click.

You're in luck, I have that exact motherboard and processor! wink.gif
I've gotten to 4.6GHz before I saw issues so I keep mine at 4.4GHz and it's 100% stable.
Here's a step by step:

  1. Go in to M/B Intelligent Tweaker
  2. Advanced Frequency Settings - 44x
  3. CPU Ratio - 44x
  4. Advanced CPU Core Features - Press Enter
  5. Internal CPU PLL Overvoltage - Enabled
  6. Real Time Ratio Change in O/S - Enabled
  7. Intel Turbo boost tech - Auto
  8. Turbo power limit (watts) - set to 150
  9. Core current limits (Amps) - set to 150
  10. Intel Turbo boost tech - Disabled
  11. Press Esc
  12. Advanced Voltage Settings - Press Enter
  13. Load-line Calibration - Enabled
  14. Dynamic Vcore - +0.050v (make sure it's + not -)


Now press F10 and press "y" then enter.
Hope this helps! Obviously if you just want 4.2 then change the multiplier to 42 instead of 44 biggrin.gif

can we set it manually? I read that Vcore has not to pass 1.37 value cause it can deteriorate CPu and do some mess. In the way you wrote are we sure it is stable under that value?

Thank you for the patience.

You can set it manually, try 1.33V to start off. That should be stable at 4.4GHz smile.gif
