    Re: Clarckdale oddness?

    I hear ya, and you know what sometimes they are wrong too. Like sometimes 124 can mean you need more Vcore instead of Vtt, and also sometimes they actually do mean you need less (Normally when this happens it is less Vtt)

    Thanks, if you need CPU multi 22 then all you have to do is manually set it and disable turbo boost. I have to say though, even CPU multi's can sometimes be terrible to use, not always though, but generally they take more voltage and are less stable.

    QPI, set 18 (36), you are using 8.8Gt/s now which is 22 (44), and it's too much. You need to keep the QPI ideally under 8.0Gt/s to keep it stable, yes it will work higher but it will cause you issues and you wont know what is doing it, like now.

    Try these settings and see how you get along, of course you will need to tinker around a bit

      Re: Clarckdale oddness?

      Okay!

      I'm back and I'm at 4.4GHz! You tip "sometimes 124 can mean you need more Vcore instead" helped out indeed...

      The more I upped the VTT towards 1.4v the sooner the 124's started to happen, so I put VTT back where it was (1.23v), that was enough for 200fsb anyhow it seemed.

      Rule nr1 kept ringing in the back of my head, "Vcore nevermind the limits, as long as you keep it cool enough just give it what it needs..." and so I did... at first I thought 1.4v should be enough but it wasn't... so I ended up at 1.45v ... peak temp only 2c up(at 83C) from the previous 4.2GHz/1.33V OC ...

      I tested some with the QPI but in the end I just left it at 44x, it seemed fine there anyway...

      I did manage to tighten-up mem some more to 800mhz c8-8-8-19 trfc:78, trd:10 and I'm still tweaking. Still 60.7 ns but looking at the overclark thread at xs I'm getting descent mem scores, so I should be content I guess...

      So... thanks for your help and the good discussion. I'm satisfied now ...
      I'll post my final template for reference later on, after a play with the timings some more.

        Re: Clarckdale oddness?

        Nice to see you got things going!!

        Ya I wish I knew what caused the BSOD codes to be "other things" sometimes, but at least we know so when needed we can try to remember.

        I sometimes also see 124 when memory voltage is too high too, but not often.

        Good luck with the continued tweaking, let us know what you settle in for
