    Default i5 750 running all the time at x24 / p55-UD3

    i have an i5 750 not overclocked for now, i had some serious problems like freezing and BSOD and after investigations i found that i must disable EIST power saving option, this problem was seen on many many i5 processors.
    so i left the turbomode+c1+c2/c3 options enabled to save power but the multiplier is now fixed between 23-24 for all cores. 24 is normally the maximum turbo multiplier when one core is in use.
    it is safe to run with this all the time ?

    Windows 7 64x, and yeah this problem is seen with 64x version in almost all case. my system is perfectly stable with EIST Disabled.
    my voltage values are to "auto"
    cpu voltage gives me in bios 1.24
    qpi/vtt 1.1
    Dram 1.5 (2x2Gb corsair xms3 1333)

    its not the os,i asked because in win7 you can use this and it will throttle/downclock your cpu multi when idle like c1e and eist ect



    ^^ use that setting and sett those voltages manually,it will be better/cooler and more stable,you can set normal setting for both your cpu and qpi/vtt and keep your ram on 1.5v,enable eist and disable c1e,if it still freezes with those voltages then try with qpi/vtt set to 1.2v keep the others as they were

    it"s already the power plan that i use.
    i will set the same voltages manually, enable eist and disable c1e.
    and if it freezes i set the qpi/vtt but the others option ? i keep them to auto (default) ?

    What timings do you have set for your memory? You may need a little more QPI/Vtt if they are tight timings.

    i have also a remark, when c3/c6/c7 option is set to auto (default) my cpu can"t switch to x24 turbo mode when one core is in use, it stays between 9-21x so i must turn it to "enabled" to correct this, i dont know why.
    just a remark :)

    wazza300 i have a question why you tell me to disable C1E ? But i didn't notice any difference enabled vs disabled C1E, i monitored the multiplier, voltage and power consumption and there"s no difference.
