  • Overclocking and EIST control: yes or no?

    I did some mild overclocking on my CPU and was able to find a happy setting where everything is stable. When I ran CPUZ I noticed that the multiplier would fluctuate from 6 to 9 based on load. (BIOS setting is X9) Apparently there is a control in the BIOS settings called EIST may regulate power based on load. When the CPU is idle the multiplier is 6, when and load hits it kicks to 9. It is enabled now but you can disable it also. Just looking for a performance opinion here. Does it matter one way or another. For those of you that OC do you have a preference?

    I would venture a guess here and say just leave it on. If you encounter stability issues try turning it off.

    Usually you would leave this option off as you start OC'ing and then find where you are stable at. Then try switching it on and see if stability remains the same? It will reduce power consumption and hence heat, which is bad for everything in your computer.

    If however it is causing you problems like not kicking in to gear when you need the power try reading this brief little link, there are a few other things here they suggest turning off that relate to the EIST I think?

      Thanks for the link. I bumped it up a little more to just over 3.3 and it seems stable when gaming and multi-tasking other programs. Temperatures look good.
      I will resist the temptation to "fix it" any more. The low idle seems fine.

        Good to hear. Just make sure it is kicking up the multi in applications when you want it to. If it isn't then you may need to turn it off?
