    Default X58A-UD7 V1 - F9a bios - CPU speed issue

    I have just updated the bios from F8g to F9a using @bios. The update went fine, but I forgot to check the option to erase DMI Pool Data as part of the update process. I did save the updated bios with optimized defaults, then rebooted and entered my overclock settings.

    The CPU Vcore has been set to Normal, which I thought allowed the i7-920 CPU to automatically reduce voltage and speed when full voltage/speed are not needed. I can no longer find in this bios the other settings that allow the system to reduce CPU power. I know there was a setting (EIST?) and maybe another setting to allow this. I am using the Balanced power profile in Windows 7.

    CPU-Z is showing that the voltage is reduced to the CPU when it is not running hard. But the BClock, Multiplier and CPU frequency are not showing any reduction from the overclocked levels (even when the voltage drops) as they did in the prior bios.

    Where are those settings in the F9a bios to allow CPU speed reduction?

    And, why is CPU-Z not showing a CPU frequency, multiplier, etc. reduction yet is showing the CPU voltage reduction?

    Could be just incompatibility issue with that BIOS? For CPU to throttle down you need eist,c3 and c1 enabled,you can always flash back to previous BIOS if your having issues

    Thanks, guys. With your help, I overcame my blindness and found the C3 and EIST settings and now everything is fine.

    I remember reading that these new bioses have the ability to display a GUI so that some settings can be changed within Windows. How is that done, and do you recommend that method? It certainly would be easier.

    EDIT: Sorry. To be clearer, I am not talking about EasyTune. I thought there was something in the new bioses that allowed direct control of settings from Windows. I may be just thinking about something I read about a manufacturer other than Gigabyte though.

    Your better off getting to know the BIOS,it will be more accurate and reliable,any BIOS oc or settings can be saved to a profile in the BIOS if needed,any Windows based oc software won't be as good imo

    OK, thanks.

    One more question. If I am using the C3/C1, EIST and VCore (set to Normal) to throttle down my CPU, should I be choosing Normal for any of the other voltage settings? I am thinking of QPI/Vtt, DVID, CPU PLL, QPI PLL, ICH core, IOH core, ICH I/O, and maybe some others.

    The others are fine on auto unless high ocing or running sli/xfire,I would set dram voltage according to ram,and qpi/vtt around the 1.3v mark but that depends on what auto is using,if its using less than 1.3v and its stable then I would leave on auto,you can manually set uncore frequency to twice what your memory multiplier is then add one to it, so 8x mem multi would be 17x uncore freq and so on

    Thanks, wazza.

    I am assuming that the Turbo mode automatically adds the +1 to the uncore multiplier. I have memory multiplier of 10, have set the uncore to 20 and sometimes see 21 for uncore in CPU-Z.

    Uncore can be 2x ram multi,or +1 or +2,I tend to go for the middle number,You mean CPU multiplier? Turbo adds 1x CPU multi for turbo
