    I'm starting to think my CPU doesn't want to be run at 4.2.

    After upping the Vcore to 1.412, Loaded Prime95 and BSOD again, gave me 0x000000101 which by your BSOD errors you've posted, it was asking more vcore. Upped that again, 1.418.
    Got another BSOD with 124 error, upped the QPP again.

    So current voltages are

    CPU
    Load Line Calibration ................. [Enabled]
    CPU Vcore ...............................1.418
    QPI/VTT Voltage 1.150v ............1.435
    CPU PLL 1.800v .......................1.84

    **Edited**

    Just seen your last post as I posted this. Should I lower the VTT from 1.435 and then the uncore as well?

    Then go back to 4ghz for now, or see my previous reply

    For 4 Ghz use 190x21

    So I left QPI/VTT at 1.435, dropped uncore to x16 and x17, both crashed in first few seconds of Prime95.

    That's normally vcore is too low, here is what's what in prime

    I'm stuck not being able to fiddle with it for now as I'm at work. But once I get home if I haven't reached the too high mark I'll give it a few more attempts, see if I can get her stable.

    Just out of curiosity, at what point do you figure my voltages are getting too high? I don't wanna push my vcore up too high.

    So if I decided to drop back down to 4ghz, using my original bios posted settings, what few tweaks would I do to that to get it running at 4ghz to start off with? I think you said current settings but 190x21?

    Yes, it will take you some time to get going/stable, it's not just a plug n play kinda thing you will need to tinker around for a while before you find the general area you need to be in.

    Voltages, well that kinda depends on your temps, but you want to keep Vcore under 1.5, and Vtt under 1.5 as well for daily use.

    Yes, use 190x21 for 4Ghz. I think you can do 4.2, you just gave in to easily :)

    Oh I don't want to give up. I want to get it to 4.2ghz haha. I just wasn't sure if I was reaching the unsafe mark for voltages on my CPU.

    I guess that's the paranoid side of me.

    So at the moment I just upped my vcore a little more, and copied down all my bios settings again just to post them on here. I want to make sure I am not missing something you told me to put in the original.

    **Edited**

    Prime95 crashed in first few seconds again, BSOD with 124 error.

    I'm reading over that prime95 post you linked, trying to get a feel for what it's saying.

    Basically to try and find out if it's my vcore I need to run the Large FFT test. Says it only fails if the vcore is waaaaay to low. But just running that is giving me a BSOD with 124 error. So I'm not sure I should be upping both, or just one or the other.

    I tried upping both for now to,

    Vcore 1.431
    QPI 1.455

    But I still BSOD with the 124 error.

    I have all day off tomorrow so if I know which values I should slowly tinker up with, I should be able to spend a few solid hours doing that, hopefully.

    As of right now these are my current settings. I turned off HT as I don't do anything that needs it at the moment, and I had gotten to 1.475 last night with it on. So I've turned it off, and dropped my voltages down, Vcore 1.375 and QPI 1.355. I've since worked up from there to this.

    Most of the crashes have been caused by BSOD 124 error, few were 101. But I just keep crashing at same point from here it seems. Boots fine, runs no problem idle, but soon as Prime95 starts. She caves instantly.
