    Great to hear, and nice to see others jumping in and trying voltages not often discussed.

    New BIOS today (F10k), and with it a new setting, "Dynamic Vcore." So here are my adjusted settings:

    CPU Vcore ..................................... [Normal]
    Dynamic Vcore ............................... +0.125

    With these settings, my Vcore under load (such as Intel Burn Test) is the same as before, 1.248v, but my Vcore at idle is now 1.040v (rather than 1.28v) ... all, as measured by CPU-Z. The lower voltage at idle (when the multiplier steps down to 12x from 21x) results in a CPU temp at idle that is 3C lower than with the F10h BIOS.

    At 70F ambient, idle temps are now MB: 35C, CPU: 39C, and NB: 48C.

    This is perfect, IMO. At idle, C1E and EIST, together with Dynamic Vcore, reduce the multiplier and the Vcore voltage ... less voltage, less heat, more green. However, this CPU also easily runs at 200x21 = 4.2GHz ... a respectable overclock (and it definitely isn't maxed out yet) ... without any change in the BIOS settings.

    Sweet!

    Kudos to Gigabyte for the F10k BIOS.

    good to hear about the new bios. i'm still running F9 here since i have a 24/7 stable OC.

    with less QPI PLL were you getting any 0xc0000005 exception codes with programs crashing?

    i've found that when i run my ram at high frequencies with a high bclk i need 1.24v QPI PLL to stay crash free for more than 2-3 days. the system itself won't crash or freeze even after 10 days like this, just certain games and programs. i'm about 80% sure this is my memory controller becoming unstable because if i bump my ram down from an 8x multi to 6x i can go from 1.64v vDimm (1600mhz 9-9-9-28), 1.34v QPI and 1.24v QPI PLL to 1.5v vDimm (1200mhz 6-6-6-14) 1.28v QPI and 1.1 QPI PLL just fine and after 5 days nothing has crashed.

    So you are keeping C1E and EIST Enabled?

    i thought c1e only kickied in on normal cpu volt setting and anything below,anything higher it doesnt come into effect? i think your seeing the voltage rise as its under load it will only use what it needs you might aswell disable c1e if your using above normal setting ie 1.8750 volts

    i believe you are correct wazza300. i have noticed that when i manually set the vcore, the voltage does not change. however if leave the voltage on 'normal' which work works up to 190x21 for 3.99ghz, vcore is at 1.24v (1.2375v IIRC). i intended on using my machine to fold so i went with 200x21 with no power saving features since its at 100% CPU usage 99% of the time.

    yeh you can only clock so high on normal,then you have to disable c1e and raise voltage,are you using balanced power saving feature in win7? i am it cuts my clocks to 2.5ghz when not under load and jumps to 3.8if needed,you could try that and save some heat at idle...or just stay on high performance

    My euphoria was premature. While I'm stable under load with Dynamic Vcore enabled, I suffer from random instability (freezes) at idle. I've tried to tweak other voltage settings to reach stability, but so far have been unsuccessful. For the time being, I've reverted to my prior settings (but am keeping the F10k BIOS).

    As it turns out, the F10k BIOS is not stable with the settings that I was using for the F10h BIOS (random system freezes when idle, or sometimes triggered by a mouse click, always with CPU usage of less than 1%). While I could keep experimenting, I have chosen the path of least resistance, and returned to the F10h BIOS.

    It is unfortunate that they never disclose (in detail) what has been changed from one BIOS version to the next. It would make it so much easier to adjust one's settings.

    Comments:

    BIOS: F14i
    OS: Windows 7 Ultimate x64

    Idle temps (@ ~70F ambient): MB: 40C; CPU: 41C; NB: 53C; CPU temp at full load (Intel Burn Test): 63C

    At Idle: Clock multiplier = 12x; Core voltage = 1.040v

    I have not tried to go beyond 4.2 GHz, but I have no reason to believe that the system can't be tweaked further; my current voltages and temps are relatively low.

    My experience indicates that there is no need to disable C1E and CIST to achieve a significant overclock with the i7-920 D0 stepping. Further, C1E and CIST had no effect upon stability at idle.

    I earlier reported problems with random freezes in Windows 7 x64 at idle. These appear to have been largely software related.
