Help with i5 3570K


I recently re-installed my OS and updated my BIOS losing my OC settings, i did have it set at 4.2GHz.
Now I've been trying to get it back to that but for some reason it doesn't stick... In my BIOS my CPU Ratio is set to 42 but when i stress test using Prime CPU-Z and HWiNFO only show's that i reach 3.4GHz max (Stock speed for the CPU).

CPU-Z does mention that my CPU Turbo is a multiplier of 42 and i'm unable to disable Intel Turbo Boost Tech in my BIOS

Any idea on this?

My specs:

AsRock Z77 Extreme6
Intel i5 3570K
CoolerMaster 1000W

  1. Try clearing CMOS and trying again.
  2. Just tried clearing CMOS didn't work.
    Not sure what's up.
  3. Did you reinstall all the latest chipset and motherboard drivers from the ASRock website?
  4. Yup all drivers and chipsets are upto date.
    I dont know if this would make a difference but i've recently RA'd my gfx card so its currently running on the intel graphics until a new card is sent out.

    here is a screenshot of HWiNFO, in the BIOS it tells me that the CPU speed is 4.2GHz but here it says otherwise...

  5. You are overclocking by increasing the chip multiplier right and not just the Turbo multiplier? You can do it both ways. That's what it looks like anyway. The only other thing I notice is your RAM is at DDR3 1333. You need to enable XMP to run at it's rated DDR3 1600. Should not have anything to do with the CPU clockspeed though.
  6. I dont have turbo enabled apart from Intel Turbo Boost Tech but i cannot change this setting while not on CPU Ratio Auto....

    heres a screenshot of my BIOS

    the above is without any OC just stock BIOS settings.
    To OC i just change CPU Ratio to All Cores and change the multiplier to 42 then adjust voltage.
  7. Try CPU-Z and HWMonitor and see what they report your CPU speed to be.

    Get both here.

    When BIOS and Windows report different things that sounds like a driver to me.
  8. Heres a screenshot of both CPU-Z and HWmoniter still getting the same information.
    It does mention that my turbo boost is 4.2GHz but i cant find anywhere in my BIOS where to turn turbo off, as i said when i change the CPU Ratio the setting"Intel Turbo Boost Tech" is untouchable.

    below is a snippit from CPU-Z report.

  9. You can't turn Turbo off before upping the multiplier? Turbo should be disabled before overclocking.

    You can tell BIOS to Load Failsafe Defaults or whatever ASRock calls it and try starting over. Just make sure your SATA ports are set correctly before rebooting into Windows.
  10. Im having the same issue with extreme4-m bios 1.40 windows was ok with windows 7....multiplier locked to 38...when i try to change it,it just keeps returning to 38...tried keyboard + and - but still max 38
  11. yer not sure anymore, reset to stock, updated BIOS and all drivers/chipsets i think AsRock may have made it turbo on all the time not sure, HWiNFO tells me that 4.2GHz is the turbo speed, but try as i might i cannot disable turbo while changing the CPU Ratio manually.
  12. Dude you have max non turbo ratio lower than max turbo ratio.. As someone else said - if you have having trouble with turbo disable it completely.

    I do not have that type of mobo bios to play with, but it appears to me you are entirely the wrong section trying to overclock turbo etc....
