I don't believe this would use crypto-extensions (though I am not entirely sure of the software stack to be honest). I re-compiled a newer release and managed to achieve roughly 12.1-12.5 (the Pi v3 is supposed to manage about 10.3, the Pi v2 only pumps out about 5.2).
I'm having trouble with every distro I've tried so far though;
- the stock Debian continues to fail (perhaps 6 out of 7 boots fail) with mouse/keyboard working for < 1 sec and then stopping
- Xenial Mate has been the most reliable however the window manager stops after a while and you can't click on anything (mouse/keyboard seems to still respond but to no avail)O
- DietPi with XFCE works until the screen blanks (power save) and then it never comes back again but the OS continues to run
I'd ideally like to use a very close-to-vanilla Debian release (I prefer that over Ubuntu forks), I've read of some of the issues being known to date so I am presuming it's just the early build of some of these OS's.
I've been monitoring temperatures when running the mining app and I'm hitting 72 degrees C an ambient temperature room of <20 degrees C, I'm currently looking for a workable passive cooling solution with a very tall sink or a way of mounting a much larger sink on top of some copper shims; still working out how best to do that though, I suspect that temperature isn't healthy. I'd love to get this thing up to 1.5ghz and test the miner out, I'm presuming current limitations relate to temperature concerns and the ram speed shipped on some boards.
