    The weird thing is temps aren't the deciding factor on how high these chips clock.

    Certainly not in this case. I believe they were prior to delidding as the chip I am using definitely has more headroom now.
    I just played Diablo3 for an hour and the CPU has averaged 38C and has a peak of 46C. This is with the water in the H115i at 35C.

    Clarification.

    Prior to delid I ran in to thermal limits easily.

    I disagree. Temps are 80% the limiting factor. Once you are in the 80 degree range, stability can be hard to find and takes more voltage to compensate, the power limits come into play. Even some suffer in the 70's.

    For the rest, they just have a MHz limit regardless of cooling unless you are going sub ambient.

    Hi Team,

    Should EIST (Speed Step) be enabled or disabled?

    I am manually setting my cores to 47 and volts 1.200

    Enhanced Turbo = Disabled

    Intel Turbo Boost = Enabled

    C-States are off

    Windows Power Plan = Balanced.

    With EIST enabled my CPU downclocks for idle, which is what I want. Trouble is, without anything running, the core speed fluctuates rapidly between idle and max.

    With EIST disabled, the CPU remains at max clock, with the resulting temp being higher.

    Am I missing something?

    Cheers

    EIST enabled ...
    It's a power saving measure. So when your machine requires processing cores & Mhz rise rapidly. Normal
    Ha :p But your killing me! I'd be overclocking the shit out of it.

    Don't break it crazy man ... really not necessary to burn it up like that.
    Get a 53x Cinebench R15 going looks like it will be really good. :wired:

    And why do you care? If the average power consumption is low, does it matter if the clockspeeds bounce around?

    Honestly I think you're just seeing a change in frequency scaling behaviour. It's been common for some time in the mobile world to "race to sleep" - rather than take longer to do something at a low CPU frequency, speed up, get it done sooner, then head back to the lowest power state.

    that's what cores do. they bounce around.

    Yes what your missing/not realising, is that even though you have no programs running in the foreground, Windows then allocates priority to background tasks and it is these background tasks that cause your cpu utilisation/cores to go up and down based on whatever they are doing. It is how Windows is designed to function.

    Thanks for all of the replies. I appreciate it. Understand now that it is normal behaviour. Never noticed my 6700K doing that. I did notice that when running a game that the CPU frequency went to max and stayed there, so it should not affect game performance.

    A few of the articles I managed to find, said to leave EIST off and let the CPU maintain max clock for better gaming performance.......

    Working on my overclock with my 8700k delidded thanks to headin. Anyone ever run into an issue when shutting down windows that the PC turns itself straight back on? Gaming 7 mobo. This only started to happen after I overclocked. Also reset all mobo settings back to default but it still does it :(

    Doubt Z370 Shane, more likely Z390

    More monies to pluck from my butt. :tired: So my guess would be $750AU 8 core & $550AU Apex z390
    Start selling more older Retro parts I have plentiful in time for this

    people who bought that have had it and using it for months now and will continue to do so for the next 6+ months until this is out. even then I suspect that the 9700k may be priced not too far off the x299 price of the 7820 like the 8700k and 7800x are now.

    More than likely it will but I prefer my steaks medium, not well done.
