Despite your continued unwillingness to type in coherent English sentences....

1) That's mischaracterization of what I said. While I'm certain that you can take excerpts out of context to support your position, my position is, was, and always will be that:
   a) The frequency is set in the PIC.
   b) When the whole board is "underclocked" to a given frequency, many boards contain chips that would actually be overclocked to a likely unsustainable frequency (i.e., a chip PICed at 415 set to 500).
   c) When a device has an inherently diminishing ROI (which is compounded daily by increase in network size and bi-weekly by diff increase), manually setting that device to intentionally further reduce ROI is counterproductive.
2) I'll believe that Bitmain will scrap a great many hours of writing code which physically protects the equipment that they sell (and provide warranty support for such unprotected devices), simply to pacify a handful of hobbyist consumers, when I see it.

Edit:
3) Bitcoin is at 4.24x since Jun '16:
    a) If you haven't been in at least that long, then you lack the experience to validate your belief system.
    b) If you have been in at least that long and you're not at a point where your ROI* is greater than 1.4 (theoretical should be ~1.7-1.85), then you lack the business acumen to validate your belief system.
    c) There is an almost 100% certainty that anyone that is disbelieving of 1a falls into the "not" portion of 3b.
