its just random, sometimes it boots without any trouble @ 4914 1.35 prime stable.
But sometimes i get a bootfailure ''due to overclocking'' and than the debug post is showing 4E and than it won't even boot at 4600 1.35 as before 4914mhz.

i have set my PLL at 1.8 manualy, so i dout it wil be that, just can't beleave it. Its like an old diesel some times it starts right up and a copple of times it just hangs on 4E error/bug, i also first thougt my cpu was already degrading, but its just and bug that occurs mostly when overclock fails.

edit: sometimes i can trigger it manualy.
- first boot into windows with a most high stable overclock
- than push the resset button wile in windows.
- as soon as you wil reboot again (and my gues is true) you won't be albe to boot at the same maximum stable frequentie as before.

don't know i'm running through SVID (auto) the same settings i posted a page back of my 24/7 OC.

I'm talking about the "PLL overvoltage" setting. This has nothing to do with the PLL voltage and doesn't affect the pll reading either. Sin measured it and the pll voltage measurement is unaffected by the CPU PLL Overvoltage setting. The cpu pll overvoltage setting allows higher multipliers to work, but causes strange OC failures, even at stock settings that would be fine with it disabled. But you need it enabled on some cpus to get high multipliers to work like 48+.
