    Default P35-DQ6 and E8400

    Hi guys,just bought new Wolfdale E8400 (VID 1.1125V).So far no problem(bios F7e).

    My first attempt,V-bios 1.26875,Loadline enable,temperature 49C idle.
    Anyone,with same CPU 45nm to share experience?

    With Loadline enable in bios,Vdrop in windows is only 0.008V(idle/load).
    My setting 1.40000V in bios,CPU-Z show 1.39200V for 4.2 GHz

    I've always been wondering if the numbers achieved by raising the FSB frequency can be considered 'real'.
    You can't raise the cpu-frequency directly with today's processors, so you get the derived value from FSB and multiplier, but isn't that only an imaginary number and the actual overclock is only the raise in FSB?
    Feel free to educate me on that one, i never really looked into that topic.

    So far,after 2 days of testing my conclusion is that I already rich the limit of 4.2GHz,with my memory(PC6400) and HSP(Zalman).With new memory(PC8500) and Thermalright-Ultra120Ex,can rich up to 4.5 GHz.Beyond this,only water or phase cooling can achive higher speed.
    To Rewl,very good overclocking Guide for E8400 is HERE
    I am very happy with P35-DQ6 and present bios.End of week receiving this two components and hopefully post CPU-Z with 4.5GHz.

    Hi all,
    One question for Janus-DDR2 OverVoltage Control
    Since today I change memory with higher operating voltage(2.2V~2.3V) or (+0.4~+0.5V) in bios,once I set more then +0.25V I cann't adjust voltage anymore(in present setting).To do this must choose Load Fail-Safe Defaults or press F12 to Load CMOS from bios(another setting) and start again.Any another solution than this?

    Hi,all.
    I have another isssue with bios F7e.This is regarding M.I.T. CPU Voltage Control.
    Up to 1.60000V in bios all increament is set to +0.00625V,increment (rise) above 1.57500V,in windows(Everest,CPU-Z,SpeedFan,etc...) voltage is always
    1.56800V,even I set in bios 1.60000V.
    Another thing is that after
    1.60000V is 1.65000V-1.70000V-1.75000V-1.80000V,etc.. is mean increament
    of +0.05000V.
    The last bios from Gigabyte came 3 days ago-F7d (released 01-02-2008) as shown:

    In bios missing "0.5 multiplier" for 45nm CPU !Tested (same MIT voltage problem) and flash back to F7e.

    The speed of the CPU is derived directly from the speed of the FSB. Its "actual" speed your CPU runs at is the FSB speed multiplied by the CPU multiplier like you said. It is very much a real real number.

    Right!!! And any benchmark at both settings will show you that

    *EDIT*

    Forgot, Yeah I have similar CPU. Here is what I started it up with on air.....waiting on my WC to get all here.

    Can you give us some info on your WC setup? :-)

    What else are you interested in, I also bought many smaller items here and there, but those are the main things.

    I will post some pics once I get it all setup next week or so
