  • 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?

    Re: P35-DQ6 and E8400

    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? :-)

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

                      Where are you getting a 1.0625 VID??? I know Everest shows a Core Voltage range under the Motherboard-CPU section. What VID reading does Real Temps show??? My Real Temps reading shows 1.15 the same as Normal CPU Vcore at the bottom of the Bios MIT section.

                      I see core voltage of 1.296 in both CPUZ and Everest. When you first posted VID was 1.17 in MIT. To get core voltage of 1.296, the MIT must be set around 1.33???

                        Re: P35-DQ6 and E8400

                        VID is from CoreTemp, and yeah It could be wrong as RealTemp shows 1.1750 but they both could be wrong who knows till it all catches up

                        My CPU when I first started it My MIT section Auto was using 1.08 something I think. I have booted it at .080V to setup RealTemp and it ran fine at that low voltage, I would think it would ge even lower

                        1.296 is under load in that image, bios is set to 1.300 with loadline enabled. Any setting I choose from 1.300 to 1.3125 all is 1.296 at load. As for my Vcore compared to your Vcore from bios to windows, remember all boards differer in the amount of Vdrop and Vdroop, and this also varies in % depending on the voltage selected

                          Thanks for the info.

                          I wasn't trying to compare CPUs just offering my info.

                          I also noted that Real Temps shows VID as what MIT shows as Normal Vcore. That is the CPU voltage in MIT you can't change and don't have to remember. :) IIRC that is what you told me was the chip's Vcore.

                          I too have noticed that CPUZ reports the same core voltage when MIT is set to a certain range.

                          What I found that seems wacky is the Vcore reported voltage in the Bios PC Health Status. It seems to report the voltage with Vdroop higher than CPUZ unless setting CPU voltage the same as the MB and then the PC Health Status reports more voltage than set in MIT.

                          I am not reporting this as a problem just what I have noticed. With all the different core voltages reported by different programs I really don't know which is correct. Though Everest, Cpuz and HWMonitor do report the same Vcore voltages with Everest and HWMonitor rounding the numbers. I suppose those are the numbers to trust or at least keep in the range that I think is safe. ???

                            Well the PC health status will show higher because you are not in windows to have Vdop yet.

                            Everest and CPU-z will show you the correct voltages at idle and load, which will always be minus vdrop and vdroop

                              I apparently didn't explain the situation well.

                              Vcore set in MIT... Vcore reading in PC Health... Cpuz
                              1.15 .....................1.204................................ 1.104
                              1.10..................... 1.076.................................1.056
                              1.09375............... 1.076.................................1.056
                              1.0875................. 1.060................................ 1.040
                              1.08125............... 1.060................................ 1.040

                              As I said I am not complaining just offering my observations.
