Hey I just bought an ASUS PZ877 V LK motherboard and by default its got turboboost turned on and its running my i5-3570k at 4.4 instead of 3.4, this is causing some instability during games and i get severe lag/hang from my pc. I need to know how to turn it off. I checked the bios and couldnt find anything to disable it, only to lower it from 4.4 to 3.8. In the ASUS UI program I can manually lower it via software to 3.4 but I dont know if i need to update the voltages and what not as well. It would be fine if lowering it also automatically adjusted the voltage settings as well. Any help is appreciated.
1) Download the appropriate BIOS-version from http://support.asus.com
2) Copy the .ROM file to FAT32-formatted USB memory stick
3) Restart computer, open BIOS, open "Asus EZ Flash 2"
4) Load & apply the newer BIOS
Then change the turbo preset to 3.8 GHz and you should do fine. If you still have issues, run Memcheck to detect RAM errors / reinstall OS.
