V1.5 and V1.6 have been crashing the 16.11 driver on my 290. This happens at stock and overclocked. Actually it's weird, I ran 1.5 from release right up until last Tuesday, so about 7 days, when it hung. Since then I cannot get V1.5 or 1.6 to run stable at stock or overclocked settings. This happens with stock or modded BIOSs. V1.3.2 runs without any problem, but speed is lower.
Could something have changed server side on Nicehash that is causing the crashing? Temps are fine as it is watercooled and VRMs are staying at under 70C. Not sure what could suddenly cause the instability.
