    For each MCH ref of 0.68-0.76 I tried VTT of 1.2-1.34, so yes, whole range.
    2.00D is not an option, it's unstable for me (on previous board it even refused to boot past 480 FSB).
    What's wrong with 0.5 multiplier? Closest would be x8, hell I don't want to pump VCORE that high :)

    Ahh, I just always found the .5 multi's to cause issues and not be stable, but that is just my thoughts. If it is working for you keep at it.

    So maybe try .78-.84 MCH Ref then

    More tests!! Need... more... TOADS!!!

    If I need 1.33 or so VCORE to have stable CPU at 4GHz, how much should I expect for 4.26? A LOT. I already feel uncomfortable at 1.3 :D

    Allright, I don't think there's any point in messing with FSB and MCH voltage anymore, I must be at or close to my limits.
    I will try to get 533*8 stable at lowest possible VCORE. Gonna need help with that. If I have perfectly stable setup for certain FSB, shall I exclude all MCH-related voltages from further tweaking and only focus on CPU - or is there any dependancy?

    Oh BTW 2.00D strap refuses to even POST at all at this frequency. I guess my memory doesn't like it.

    Booted into Windows with 8*533 with 1.35VCORE. Gonna test a bit. Give me your opinions please.

    3.7 working on default will have nothing to do with likely amount of voltage needed for 4GHz. voltages do sometimes progress linearly with Vcore, and to be honest your current voltage is on the low end of that linear scale. At any point, the CPU can all of a sudden want more voltage than you think. The point on each CPU is different. You can have what seems like a CPU made by God himself, only to find that to get another 100MHz you need 0.09V rather than the 0.03V you used to get 600MHz of an overclock before.

    If small FFT fails, then you can be at least 85% sure that you need to use more Vcore. MCH ref likely won't help. More VTT and possibly CPU ref could, but I'd bet you'll be testing those any way. The sure fire test is give it a single Vcore bump on the exact same settings and see if it breaks 19 hours. It should do unless it needs 2-3 bumps.

    1/3V is nothing. I've seen E0 stepping E8400's with a stock VID higher than that. You have the cooling, and you have warranty up to 1.3625V. I'd be hoping you'd get 4.2GHz stable on 1.3625V with LLC on. Some E0's can do with less, and others may need more, so it could be worse. 1.34V is nothing, considering Intel feel the need to tell you you can use up to 1.3625 just to achieve stock settings. If I'm using 1.45625 with cool temps, you should have a better time of it with your higher grade CPU.

    Edit: There is a very loose dependancy reported between VTT Vcore and PLL. PLL tends to help maximise FSB for some. VTT is reported on rare occasions to help reduce Vcore needs, but that's never been the case for me, or alot of the people I've given a hand.

    Better to test more Vcore first. After you find the minimum stable Vcore for the speed you want, then try and tune things to bring it down further. As you have 19 hours stable, altering two things at once is likely not needed and it'll be a long time to find out if you have success or if you changed too much.

    Thanks!
    I tried to play around with higher CPU ref@1.2VTT only to get crippled resolution plague of mine again :D Looks like it will be VCORE all the way.

    1.4 and still failing! Wtf! I don't like the number anymore. Plus last three steps I got the resolution error again - and that's just raising VCORE. Bleh.
    edit: 1.4250 and BSOD. I don't think I can do this.
    Perhaps I am severely limited by MCH core, because I can't move VTT at all without losing bootability.

    I gave up and instead testing 3.99. 1.36 or so VCORE.

    edit: and how the hell can the temperatures still NOT drop with intake fan and ALL other holes in the case shut???!!!!

    You could try raising MCH and then try again. IMO anything under 1.3V at 533 FSB isn't awesome but is OK.

    Isn't awesome in what way? Like, too low or rather high?

    Ok 1.280 MCH.
    Now what?
    How shall I test it? The trouble is that I don't know if possible unstability would be caused by the CPU or the chipset.
    Shall I start looking for CPU or chipset stability first? OR shall I lower the multiplier and do as before?
