I wish there was a trial of this OS. I'd hate to spend $39 and not be able to get it work.
if you make a little digging you can download it free,
I did that and after week of testing i bought it
1.2.4 was a RX dag fix, but for some reason it also made my 1070's faster... was hashing at 30.2 now its going at 32.23... they probably fixed the tables which dictate the overclock speed.
config?
globalcore ??
globalmem ??
powertune ??
btw i just checked gtx1070
windows7 mem +725 (4500) 32mhash @ claymore
ethOS mem (4800) 31mhash @ethermine/claymore - same speeds
core 1550/1600 (-400) or 1700(-200) doesnt change anything
