    Double booting is perfectly harmless. Truth is, nobody actually knows exactly why boards do it, but it causes no harm. At the very worst, the board is simply deciding to make a further fine adjustment to the many settings that aren't visible to the user in the BIOS. It will cause no harm to your PC at all. Logically speaking, if the board double boots, but all tests certify relative stability at the over clocked settings, then there isn't really anything wrong with the settings.

    I had a EP45-UD3P which would double boot if AC power was disconnected (PC switched off at the wall over night for example). This happened at anything over 333 FSB and happened with a Core 2 Quad Q8200 @ 3.4GHz and a E7400 @ 3.9ghz. The only time you need to definitely take a look at your settings is if the board constantly boots and reboots in a loop.

    I've also had Windows reporting incorrect clock speeds. This also does not matter. It's simply a bug in Windows. Some times the OS will calculate the CPU's intended max multiplier * FSB speed, rather than actually using the correct set multiplier. This is a display bug only, and does not effect performance/stability/safety.

    If you want to over clock, then be prepared to completely give up any and all power saving features such as speed step and C1E.Sometimes an OC will be just fine with them enabled and other times it won't. If you really want these features, the only option is to lower the over clock until those features no longer cause issues. It may be possible to troubleshoot and find a couple of minor adjustments that fix things, but if power saving is a priority, I wouldn't recommend an over clock in the first place. Just raising clock speed and core voltage by small ammounts increases power draw significantly.

    i decided stay with double boot (i wont remove the power plug), its a good overclock (400x8.5), is stable even with stock voltages and stable with C1E, i found many people with the problem, righ here on this forum i found a double boot issue, i think could be related to memory timings, the problem is on multiplier, when i set 300x11.5 with 900mhz on memory, there's no double boot also known by "cold boot" or cold reboot, i think the memory multiplier is a trickery and the board dont like or dont save it, when we make a over with fsb and memory there's no double boot but in this case we are overclocking only the fsb, some say to set 2.1v on memory but the default is 1.8v, now corsair 1066 is 2.1v by default

    I only tried 3.33GHz(417x8) with default vcore untill now, but when I saw your stable at 3.4 I decided to try and now 3.4GHz(425x8) stable with normal vcore and C1E and EIST enabled. This is great for hot summer days.

    if i set vcore on auto is 1.38v(full load) and 1.41v(idle)
    if i set vcore on normal is 1.24v(full load) and 1.07(idle)

    vcore on auto on default cpu is 1.24v(full load) and 1.07(idle)
    vcore on auto on overclock is 1.38v(full load) and 1.41v(idle)

    strange

    Nothing is strange about it. The BIOS is not too smart, when overclocked it simply set higher voltages (many of them). When vcore is set to anything different from normal C1E and EIST can't throttle vcore on idle.
    Finding the right values for each voltage at certain OC is much safer cooler and usualy more stable.

    the option "pci latency timer" with 32,64,128, default is 32, i tried 64, the computer "looks" more faster, the mouse, windows explorer, what do you think? should i back to 32 ?, until now looks stable

    I always see double boot on P45 when overclocked, sometimes triple depending on the overclock, same applies to X58 as well - so I think it's normal

    I made a few video's a while back for another member on here, using X58 and Crucial Tracers so you can see the triple boot more easily

    I wonder why should it make any difference and which devides are connected to the PCI bus, surely not the the video card.

    like i said "looks" better i will leave at 64, i tried 105mhz on pci ex and dont boot, then i tried 101mhz, looks normal, but i will set to 100

    You decided not to enable C1E? Wasn't it stable?
    You can safely set CPU Reference auto. all references should be auto unless maually changed.

    If you have EasyTune istalled, check target voltage in Tuner -> Advanced -> Voltage tab. MCH Core may be set higher than default when OC and auto.
