    Don't have a clus as to what is happening with the QPI/VTT Voltage setting. The OS boots at 21X (4,2GHz) just fine, but core voltage have to be set too high for stability purposes (Prime95), I run out of temperature headroom.

    Maybe I'll just have to be satisfied with 4.0GHz?

    Try using 190x21 then and see how that goes.

    QPI/Vtt issue may be your BIOS, try a clear CMOS or update to the latest Beta and see if you can then change it.

    4Ghz is much easier to get stable at lower voltages, and not really much different than using 4.2, so it may be the best thing to do since your temps are getting up there.

    1) OK, 190x21 will give me another data point at ~4GHz.

    2) I have the GA-P55M-UD4 MB with F9 BIOS (AFAIK this is the latest and I haven't seen a beta F10x to date).

    3) I figured out what was going on in current F9 BIOS settings (via EasyTune6 voltage readouts); Memory get's set to 1.62V [Auto] and QPI/VTT Voltage get's set to 1.41V [Auto] at either 3.8GHz (BCLK of 200, 19X) or 4.0GHz (BCLK of 200, 20X). At first I found these numbers to be rather unusual, until I looked at the Intel specifications: 322164-001 (Rev. 1 09/2009) vs 322164-003 (Rev. 3 06/2010) vs 322371-002 (Xeon 3400 (i7-800 twin except 1X less multiplier) Rev. 2 01/2010).

    Table 7.4 numbers are;

    322164-001 (Max, for Min subtract 0.3V): VCC 1.55V, VTT 1.21V, VDDQ 1.65V, VCCPLL 1.98V

    322164-003 (Max, for Min subtract 0.3V): VCC 1.40V, VTT 1.40V, VDDQ 1.80V, VCCPLL 1.98V

    322371-002 (Max, for Min subtract 0.3V): VCC 1.40V, VTT 1.40V, VDDQ 1.80V, VCCPLL 1.98V

    So VCC (CPU) went from 1.55V to 1.40V (in line with Xeon 3400).
    So VTT (QPI/VTT Voltage) went from 1.21V to 1.40V (in line with Xeon 3400).
    So VDDQ (memory) went from 1.65V to 1.80V (in line with Xeon 3400).

    In light of these revised numbers, I would strongly suggest that Gigabyte update all their BIOS to reflect these new numbers (e. g. for QPI/VTT Voltages change pink colored voltages between 1.22V and 1.40V to white color for GA-P55M-UD4 future (F10) BIOS). Plus updated BIOS's supporting the most recent Intel CPU's (e. g. I7-875 and I7-880) for all compatible LGA1156 Gigabyte MB's.

    I and the Gigabyte user community would greatly appreciate your cooperation in this matter.

    TIA

    Very Respectfully,
    Francis E Sargent

    So the max Vtt also changed for non Xeon CPU's too?

    Vtt and Dram really don't matter unless you are not setting them yourself, if you are then all you need to ensure is that you keep QPI/Vtt within .5 of the dram voltage and you can use and Vdimm you like as long as you keep QPI/Vtt within the .5 limit and under Max - if you want :)
