    There are three different MCH settings; guessing you're talking about the "MCH Core"?
    Sorry CPU VTT is also known as termination.
    When I mentioned MCH i meant core voltage yes.

    The settings Outer Marker may work on a good E8400 chip, they didnt work for me however. I also have the C0 not the E0 which has been known not to OC as much.

    Post your current settings and we can see if you can still bump that vcore up even more.

    Current settings are on what you suggested previously;

    Upped the "MCH core" to 1.3, "Vcore" to 1.35, "CPU Termination" to 1.24 and the "PLL" to 1.6.

    After Outer Marker's luck didn't extend to me, I put it back to those settings, so currently running...

    I left this benching all day in prime, 12 hours, no problems... Temps max around 49 Degrees acording to "Core Temp", around 45 according to "Realtemp".

    Are any of those AUTO settings considered dangerous? Because I'd rather run at stock than run a BIG risk of damaging it.

    What should I try lowering first to bring down any of those numbers if I were to try...? Wanting to have them as low as I can get away with as everyone does...

    Your temps are good and the vcore limit of your CPU according to intel is 1.4v, so its fine.

    If you wish now, you can gradually step by step reduce voltages (start with the vcore and termination) until you find the min voltage.

    Or, you can move on to reducing your memory timings step by step.

    Its up to you really, if you dont have the time, this overclock is just fine and you dont need to worry about any other settings if everythings stable.

    Another thing you can try, if booting didn't work, is to try my settings again, but use 2.00D as the strap. Perhaps the 2.00D is too tight for your memory which is usually why you get booting problems.

    I see that you are able to boot fine with 2.00D, so give that a try with my settings and see how you go. I know the C0 won't overclock as high as a E0, but a 3.6 should be within reach.

    I see some things you should change before or while you are trying to lower voltages >>

    What you could try is more Vtt and a lower MCH Ref. Some memory sticks just will not work with the B Strap above 350-399 FSB, so you may have a set that wont, but you can still try for sure.

    I would try higher Vtt maybe 1.25-1.32, but set MCH Ref first. I would try MCH Ref of .70-.745 and see if it is any better, try each one of course. Be sure that you set Vtt back to 1.20, then adjust MCH Ref, then go raise Vtt back up to the value that you plan to try out. See the link in my signature if you are not sure about how that works, I provided images and several examples
