    People, the nail is not in the coffin yet, the case is not closed! There are
    still people that cannot run there initial stable clocks without
    more vcore added, mrcape, and myself included, just to name a few.

    I have tried other high wattage PSU's and that has not fixed anything.

    One theory that got started was the voltage spike, some people have
    posted graphs (myself included) showing enormous vcore spikes 1.7v and greater, and some have posted graphs that are "smooth as baby skin".
    I have graphs that are smooth as baby skin too, and in fact it took
    me 3 hours of running OCCT in 10 minute intervals to get the 1 graph
    with spikes. Like I said earlier the sample rate of the voltage monitors
    are low, (i.e. 1hz, 1 sample per second) literal hundreds of vcore spikes
    could occur between samples.

    So this leaves some new questions:
    1. Do these 45nm cpus degrade initially to a point and then stop degrading?
    2. or, are the huge vcore spikes the culprit (ultimately causing degradation)?


    Also I created, and built this:



    This filter should make the 12v going to the CPU ATX power very clean, and
    hopefully arrest any spikes comming from the PSU.


    This is what my vcore graph looks like now:


    So Im hoping to not get anymore spikes, however even with the vcore this smooth I still cannot run my initial clocks without more vcore.
