    What CPU Cooler do you use?

    Thx guys, before I go and up the voltages some more I'm going to lap my cpu in hopes of lowering the temps. Just not comfortable pushing 71 full load. Will report back in few days and hopefully be stable. As mentioned earlier, I tried the proposed voltages and this time my 4th core got an error at 7:52hrs while the others all passed until I stopped it at 15:17hrs.

    The results are in! After some voltage tweaks Intel Burn Test passes like a breeze and puts P95 load temps to shame lol. 68, 62, 63, 68 degrees from cores 0-3. P95(blend) test just passed 13 hours and zero errors. +1 :D
    Windows vcore shows 1.216V but drops to 1.200V under load. Now that everything is stable and temps are in check, time to load up to games and apps and get rockin'! Settings used to achieve this oc are as follows:

    You should enable "CPU Thermal Monitor 2(TM2)"

    ^Good call, I had it disabled during testing as I was monitoring the temps myself. But now that everything is okay, will enable it. :)

    A question that's been on my mind, the MCH/DRAM Ref voltages, I have them set to Normal. What does normal setting actually mean? Also, setting it to Auto or Normal, which is preferred?

    Auto Means the board will decide the voltage based on settings used, normal means it will use stock values. Auto or normal is not suggested for the following voltages when overclocking: Vcore, Termination, CPU PLL or MCH Core. All Reference voltages should be on Auto as well, unless you have manually set them and know how to do so properly

    If you need help with anything else here let me know
