Are you overclocking in the UEFI BIOS, or are you using software?

If I'm not mistaken I dont think you need to mess with the turbo. The only thing you need to do with the unlocked chips is adjust the multiplier and then adjust the voltage accordingly, and then you can tweak some other settings but its not necessary.

ooh sorry for the late reponse i have official just moved..but i just messed with the cpu ratio. didnt reallie mess with anything else left most with auto.
post #5 of 16
Auto is never good you should manually set voltages to as lower values as possible...auto tends to over-volt..
post #6 of 16
CPUz shows the current voltage and clock. If you want to see your overclock, run prime95, or download hwinfo64 or coretemp.

so im using the asus p8z68 motherboard do i change my cpu voltage to manual ad just go from there?
post #8 of 16
Yes set a manual voltage and do a prime95 test for 12 hours or so. If you BSOD Feed a notch more of voltage, you can mess with the PLL, VCCIO also but first start small just vcore and the turbo is disabled technically when you OC Disable c1e and c3 c6 eist for no Downclock in idle but it saves power and cools down the chip during idle so why not use it. im running fine at 4.6 ghz with power saving.

What do you mean by "and for some reason it doesn't show in CPU-Z"?

 

Regarding Turbo Ratio:  that should be set to "By All Cores".

 

Regarding CPU Ratio: that should be set to Auto.

 

I think this is why you're not seeing it in CPU-Z.

That's a good way to start.  Once you've reached a point where you are happy with the overclock and have tested it to be rock-solid stable, you can switch to an Offset voltage.  At that time, I can help you set the offset voltage.
