How to disable CPU powersaving on Gigabyte boards?

Smoogels · 9 Feb 2013 at 07:35

Hey.

How do you stop power managment settings for your CPU in Gigabyte boards (Z77X-D3H)?

I have overclocked my 3570K to 4.6GHz and it always run's at 1.28v yet the CPU still clocks down to 1.6GHz at idle. How can I stop it from clocking down?

Here are the options I see:

I tried turning off EIST but then Windows only detects the speed as it's stock 3.4GHz even though in BIOs it's set to 4.6GHz.

Thank you in advance for your help

Turn off EIST then check your CPU with CPU-Z for an accurate reading.

When EIST is turned off, CPU-Z says it's 4.6GHz but all other software (such as real temp, Windows, sidebar gadget) all say it's 3.4GHz. CPU-Z seems to be the only application I have which shows the overclock.

How reliable is this?

Thanks.

If you are unsure, run a benchmark before and after turning off EIST, and see if they're similar.

You need to turn c3/c6 state support off

use an updated version of cpu-z

keep all power saving on,its usefull,its not the pc its cpu-z not showing correct idle voltage

MORE SPEED I'll give that a try in a second, thanks

Done that and the problem still persists

I have got the most recent version but it's still displaying the manually set voltage. Tried with AIDA64 to but that still says the same.

Look in easytune/cpu

Yep, still says 2.8v even when it's clocked down to 1.6GHz.

All to do with the a power plan on windows.

Change the power plan to balance will show CPU-Z 1.6GHZ.

Thank you, that was the issue.

My computer was on balanced by default so I changed to high performance and the CPU stays at the overclock

I then created a new power plan based off balanced but just modified the processor section and it seems to work perfectly.

Thank you for your help
