I guess i eat my words but I still have faith hoping to see it tweaked enough for some one to come up with a nice bios edit for Zcash
my 280 just stops with no reason and closes the app no matter what flag is set. noticed others had the same issue with 280
both of my r7 370 just stop no apps closes nothing and says hit enter to continue.
all nite my three 470 seemed ok and are still running .
log was put in for future use it doesn't say much,I guess .
no flag or switch seemed to work for me .
last thought they start up mining great then about 15 mins some times less speeds drop off a lot not like it was adjusting , I hope that's not how it works, can't really say we really don't know what speeds we should get, it still to unstable better but still not stable,over clocking doesn't seem to do much at first it does then give it time it crashes or expected speeds start dropping or cards stop for no reason.
I stay connected now Plus side, negative side they stop for no reason.
went back to
http://zcash.flypool.org I like it the best sense it's not really a pool issue like i was hoping, that, i think would be easier to fix .
