STRANGEST THING Turbo Ratio in BIOS ok but won't change in Windows 8.1


Ok, so here is the story. I used to overclock a lot but haven't done it in a while till yesterday. This is the most strangest thing I've ever seen

I started overclocking step by step changed turbo ratio up by 1 each stable boot. I received a stable boot in turbo ratio 43 so proc was running at 4,3 Ghz. Wanted to go up some more so went to 44 but after I booted to windows 8.1, it stayed at 4,3 Ghz.

So here is the strange part, even if I lower it back to 38 or whatever turbo ratio I use, windows will still run at 4,3 Ghz! And what's even worse, when I change my vcore it changes in windows but my clock speed stays the same!

I'm at work atm but my guess is to reinstall windows right? 'That's the only logical explanation or am I wrong? PLEASE HELP ME


ASUS p8z77-v
Cooler Master Silver Pro M1000 (1000 Watt)
i7 2700k
Corsair Vengeance 2x4 GB 1600MHz (but running on 1333MHz)
660TI (soon 660TI SLI)
Windows 8.1

Any help is appreciated!

  1. so just to be clear.. was overclocking slowly from 3.8 ghz and it was all working up to 4.3 ghz. now setting it higher or lower is ok in the bios and gets calculated good in the bios. but in windows it stays at 4.3 ghz. changes in vcore gets accepted in windows but changes in clock speed doesn't. even if I put everything back to default, windows cpuid and other hardware monitoring tools say 4.3 ghz.
  2. When you say you put everything back to default, did you go into the BIOS and hit F9 to completely reset everything? Or did you simply change settings back manually?
  3. AMD turbo core doesn't kick in until under load. However, it is recommened to disable while overclocking. And if you are using a program to overclock in Windows, you're doing it wrong. They conflict with BIOS settings, and aren't very reliable. You want to make all your changes in the BIOS, not a program, unless you are increasing the voltage by one increment to test stability without having to reboot-but then Don't forget to make the change in the BIOS.
    And do you set it to default, or optimized defaults? And do you set the BIOS to default? Or the OS default in the program?
