    Looking good, have you tweaked things anymore? About Vtt, you may need a bit more than 1.20 for full stability since you are overclocked so high. So if you have issues try 1.25-1.3 and see if that helps any
    Tried OCCT for 5hrs linckpack and was fine with 1.2v VTT.

    What else I should see/tweak?

    Nothing then, sounds like you are fairly stable. You could run Prime or Orthos for 24 hours to be sure. Then if you want try lowering voltages, but that can take a lot more testing

    Last night, I restarted the PC and when it's booting restarted again and says "Last overclocking settings fail..." so, I put VTT in 1.24 for now... I would test in later.

    Ya, sounds like you are just not as stable then as you thought. Keep at it though, you are almost there.

    Post back if you run into issues and need some advice

    Hello Gang

    I just got the same setup the OP is using and have spent most of the weekend here reading and trying different things on this setup.

    I wasn't sure weather to make a new post or not, because things are moving along ok.

    Here's where I'm at right now ... after loading bios optimal defaults
    and doing some tweaking from some other post here on the forums.

    I'm kind of lost now ,whats the next big step?
    I keep inching up the FSB up 3-5 mhz and testing for 20 - 30 min of Prime waiting for a failure or lockup.

    any hints on what I should go for next?

    Again thanks for this Great Resource, I'm having a great time learning :)

    What speed are you reaching for? What cooler do you have?

    I can advise you on settings for any speed if you want, or otherwise all you need to do is loosen things up and push the FSB, Vcore and Vtt a bit then set what you want to try out.

    Well I'm really not after any specific figure... I would just like to see how far it will go and remain stable enough for everyday use.

    As you can see now my ram is doing alright @ 876 and the cpu temps are maxing out at around 65-67 running prime for 30 or so min.

    I have Coolermaster's Hyper TX3 heatsink. nothing special but really quiet when I'm not benchmarking.

    I'm pretty happy with the 3.3ghz OC and suppose I need to try lowering the Vcore back down to eliminate some of the heating.

    I tried 400FSB and many different settings and never found anything that would actually boot.
    Even with 1.4 vcore and 7 multiplier..but I'm not sure what the VTT was during those test's.

    You should be able to do 400 FSB, but it may take more voltage than you want to try.

    3.6 would likely be pretty easy to get stable, have you tried that yet?

    I'm @ 370x9 right now with the same settings as above.

    My cooler isn't the best so I'm trying to keep the max Temp below 70c
    The vcore is solely responsible for the Temp increase's correct?

    So my plan was to find out how close to 400fsb I can get at the current 1.375 vcore then start working the vcore down and still remain stable, if that makes sense

    Thanks for taking the time to help.
