    With last settings I got a BSOD 101 error. Upped the Vcore, and now I've crashed twice from a 0x0000009c error... Not quite sure what that is.

    Perhaps memory compatibility issues? Were you stable before at other lower clocks, I mean tested stable not just bootable/usable?

    on my 4ghz I ran stable for 12 hours. Same memory setup. Ran Linx for 1.5 hours, and rest was prime95

    I am at Vcore 1.425 and QPI 1.435. I can run Prime95 for a few moments now. Instead of instant crash. Didn't blue screen last time either, So I just lowered my uncore to 17.

    I don't want to run my voltages too high, I'm hoping to keep them around where they are now. Just not sure what other things I can tinker with to try and get it stable, without sacrificing performance. Any ideas?

    I decided for now I'm gonna stick at 4ghz. I've got a good stable build right now, and I think I can lower the voltages even more.

    Thanks for the help lsdmeasap, I have a better understanding of it all now from this, so next time I get into the tinkering mood, I can further my clock. Eventually I'll buy a new i7 and see what I can do with it :)

    Hey

    I run 4.2 GHz with BCLK set to 201 on my i7 920 C0 EX58-UD4P on a daily use and you should not have trouble reaching that too. I saw your memory timing is set for auto - set manually to 8 and then lower your QPI/VTT voltage to either 1.35 or 1.37. Set Dram voltage to 1.66 and Uncore to 17. I also run with Turbo but you decide. It should only be a matter of how much CPU Vcore you need here and I need to set to 1.41 in BIOS for mine to be stable enough to play games. If I need to run Prime95 I need a lot more juice than that. You could try to disable Hyperthreading if you only need this high 4.2 GHz for games - given the fact very few applications actually benefit from all them cores.

    what stepping is your chip? C0 or D0?? youll generally use less voltages on a D0 chip,dont bother buying the 930 either just try n pick yourself up a D0 920

    D0 is not always less voltages, I try to tell as many people this as I can because people hear this far to often and then can't get things stable because of trying to low of voltages.

    Not trying to argue with you or anything wazza, just saying. I have had 2 D0's and they both needed pretty much the same as the C0's I had tried, one did allow a bit less though but nothing like the very low voltages of the semi-majority D0's like you mention

    yeah its just luck of the draw,some c0 chips out perform d0s and vice versa,i just like/prefer to use the latest revision chips

    I got rid of the D0's I had, they proved to offer nothing more really considering the costs vs using C0's.

    Of course you are right, many D0's can use less voltages and thus have better temps too, but not all of them.

    And of course, yep my luck states that I will not be lucky :) so I always get the bad end of any draw
