Thread: i7-2600k crashes on idle and with c3/c6. puzzled

    Default i7-2600k crashes on idle and with c3/c6. puzzled

    Hi. I have a problem with my Ga-p67x-ud3-b3 board. I'm currently running an i7-2600k processor at 4.4ghz (44x100). It is 4-5 hour prime stable using the dvid method for voltage (normal + (-)0.05V offset). However, there has been a nagging problem. Every now and then, the PC will freeze when I'm not doing anything. No blue screen. Just a freeze.

    I've been exploring it further and I've found that if I take c3/c6 from auto setting to enabled, windows will freeze almost within 10 secs of booting most times (or on resume form sleep). But If I turn off c3/c6 the entire PC is much more stable.

    Maybe its my imagination. Does anyone have any tips to give about making my pc more stable?

    My ram is 8gb of corsair 1600mhz modules
    My oc settings most things are on auto except my voltage.
    My temps at max load are under 60.

    I've tried more voltage, solid voltage (no dvid offset), playing with the ram, etc etc nothing works. I've tried backing down on the OC and no response either.

    Tried using latest BIOS or beta BIOS?,what qpi/vtt voltage is auto using? Try one/two clicks more,not much though as those chips don't use alot

    Sadly that did not make a change. PC still locks up on boot if c3/c6 are enabled.

    It can only be your CPU voltage dropping too low when idle? You can raise idle voltage slightly by increasing dvid voltage,yes it will raise load voltage but will make CPU voltage slightly higher when it idles

    Have you tried disabling c1e and letting Windows throttle the CPU by selecting balanced profile in win7 power saving options?

    Try updating the Intel inf drivers too

    None of that helps. I could disable c1e but its currently stable with c1e.

    my drivers are all updated and throwing more voltage at it doesn't help either.

    Seems we are fighting the same issue:

    GA-P55M-UD2 C3/C6 Crashing with i7-870 (rock-solid with i3)

    To the op,are you using built in graphics? Tried slight increase in igpu voltage?

    I am using a gtx 570. My board is p67 board.

    I so far have zero solutions right now. LIterally 100 percent of the time, if c3/c6 is on, the PC crashes at load.

    I also have noticed that intermittently the PC will have trouble recovering from sleep.

    I'm running with limited Turbo (I could not get C3/C6 running on my i7-870 without video freezing). I will keep looking for a solution.

    PSU replacement? I'm with a 500W CoolerMaster.

    Seasonic x-750w here. I've also noted that this issue is now occuring when I'm at stock settings.

    Its really quite a puzzle. I'm tempted to replace the board.
