For everyone that have stability problems where the OS hangs or slows down to a halt, this is due to Xorg taking 100% of one of the cpu cores, as far as i can tell this usually only begins after some kind of soft crash from overclocking/undervolting, i've googled my ass off and found a few references of people claiming to have solved this problem by configuring Xorg to run from the integrated intel GPU and leaving the nvidia cards to pure computations, my linux know how is Very limited so this is more of a question for fullzero.
what do you think Fullzero?
This change could possibly improve stability with higher OC on the primary GPU; but it would also introduce other problems into the system which don't currently exist.
Using the Integrated graphics lowers the number of GPUs which can be supported; as it both uses more system resources and increases the load on the CPU significantly.
You might have noticed; other mining OSes which use this method only support 8x GPUs.
With the 12x biostar nearly here, I don't think this is the right change to make. If the biostar can actually run 12x GPUs then I will for sure; not make this alteration. If it can only support 9x or less GPUs then I will consider making the change.
