    I dont know about any software to do that, within windows, or linux.
    If you enter into dual IDA, you need to disable the speedstep, to lock in the CPU the "overclocked" state.
    However it would be straightforward to implement some sort of dependency on the CPU load, but no one yet to do this.
    Lastly in my system, disabling/enabling speedstep, disabling one of the cores, reenabling creates a ~100ms system freeze. Thus its impractical to add dual IDA modes in the regular core frequency switching scheme.

    But most importantly, the voltage, frequency set has minimal impact on the idle current consumption. The difference comes only when you use the actual thing, running something on your CPU. Even the halved SLFM modes (800-400mhz fsb cut by half) has non-measurable differences. At least a T7250, T7600, T9500, P8600 which I have tested behave like this. No idle power consumption reduction if you set it to lower speeds, perhaps only minimal.

    The higher frequencies however only a tradeoff of the efficiency of the maximum speed. For example my T9500 handles 2800Mhz with ~30-35W, but it draws only 20-25W for 2400Mhz with full load on both cores. The performance ratios are 87, vs 107 Mhz/Watt.If you get a X9000/X9100 the efficiency will be dropped dramatically if you go over 3000Mhz. I can test the frequencies such as 1600Mhz, since the voltage is locked, at 0.95V, no improvement if I cant set it to the lowest required. But an U9600 which I have seen once, draws 10W total, and have 2 cores! 160 Mhz/Watt must mean something. But Im afraid you cant have this with the Txxxx or Pxxxx series, since the minimal voltage is also locked.

    Hi all,
    I have Asus G70S chipset PM965 and CPU T9500, have problem with EIST, because i have no option in my bios. Can someone modify my bios, or help me make this option real. Please write me a mail to lucasinokiss@seznam.cz, if it succeeds, we can talk about the prize. Many thanks Lucas

    Sorry to wake up an old thread...

    I have an old Dell XPS M1330 with T8300 and discovered this thread. I went through the steps on the first post. I was able to get my T8300 into Dual IDA mode once. But I don't know how I did it. Since then I was not able to get the Dual IDA again.

    The following was what I did
    - Disable the Enhanced Intel Speedstep in the BIOS.
    - Set the Minimum processor state to 100% on Windows 7
    - Download ThrottleStop 8.0 Beta 2
    - Start/stop the ThrottleStop to get the ThrottleStop.ini file. Add DualIDA=1 to the end of this ini file.

    I must be missing an important step. No matter what I did. The multiplier stuck on the multiplier 6. The photos on post 1 are missing. Otherwise, it will help me to get it going. Any help will be appreciated.

    Hello, I have a SLAYY T9300 in a Thinkpad T61, I can eanble/disable EIST by BIOS, but can't within windows.
    Is there any modded BIOS can I use? I spent a lot of money for this processor :(

    all works but multipler won't go above 12 (which is defalut) i raise multipler and VID to maximum i tryed everything but won't go above 12
    i check power states in power managment it's 100% for both (min and max processor state
    i have dell xps m1730

    Hi Uncle Webb, Kevin Glynn , awesome job your doing , im have a T5750 and as your guided it is working and throttlestopping very well . Marvellous, Magnificent and Zealous how you takeover the arena with this throttlestop phenomenon. Previously was trying to get onto you awhile back from my email natware101 concerning my FYP where my thesis observed the overheating epidemic in laptops & scaling technologies where i made a temperature alert system. Im am interested in your contribution and approach to the body of knowledge for the greater good and a great support of your products. Lets share notes.Its going like wildfire, literally. Please advise BR, Kevin Henry.

    PS : Congrats on the most recent Obsidian initiative also just goes to show your intuitive model working for you from throttlestop and beyond this universe.
