    You mean 85C? It'll be ok, I'd say stop it if it hits 90C. That's not ideal at all, but the testing will be short and your CPU will live :)

    Try it again and see if the code is the same or not, if it is give me your settings.

    Settings please, sounds like a memory error more than anything. Possibly Uncore multi

    Try these changes

    Uncore Frequency .......................... x18 << Try last, x17 or x16 (Try to keep x18 is why i said last)


    Advanced DRAM Features:
    Performance Enhance ...................... [Turbo] << Extreme

    QPI/VTT Voltage 1.150v ............[1.335v] << Try 1.35-1.42
    CPU PLL 1.800v .......................[Auto] << 1.84

    IOH Core 1.100v .....................[1.200v] << 1.24

    CPU PLL 1.800v .......................[Auto] << 1.84 ok

    IOH Core 1.100v .....................[1.200v] << 1.24 IIRC this was to do with crossfire setups so i can leave this one?
    Is there anything i can do to find out what my error codes mean exactly? Is frustrating i dont get the same codes as you posted earlier

    NO, not really. You could run a debugger but it would just point to a unrelated driver that failed at that specific point of BSOD which would not really have anything to do with it.

    QPI/Vtt is fine way above 1.335. It is fine as long as you keep it within .5 of Vdimm

    IOH, just try it. I always use 1.24 myself and do not have any issues. Others run 5Ghz on stock, so it all depends on the board/setup I suppose.

    ok so for now ive put performance enhance to "extreme" and put IOH Core to "1.2400v" (im trying to do a couple of things at a time to work out the problem rather than all changes in one go)

    Edit: 2nd go, i upped QPI/VTT Voltage to 1.35 (still got same error as below)

    I ran linx, and this time the result was different... no BSOD but instead.....

    "Stopped upon error after 3 m 57 s!"

    I clicked on "log" in the bottom right hand corner and got this....
