lol new version 2.0.1.3 removed daggerhashimoto for 3gb cards!!! LOL they dont know till April is profitable?
We decided to drop 3GB cards for daggerhashimoto because the DAG size was getting dangerously close to the 3GB limit and daggerhashimoto didn't even run on these cards especially when they are used as primary cards. This may not be a problem for experienced miners, but the majority of NHM users are casual ones. There are so many things to consider, you know...
With version 2.0.0.8 still getting 143mh with 6x 1060 3gb no.issues
I understand that your rigs work fine, but your very specific case is not universally generalizable to hundreds of thousands of PC's out there.
Memory usage depends on a number of factors, including the OS, driver and background processes, and we needed to be absolutely on the safe side.
I would recommend you just use excavator instead of NHMv2 as the former gives you more control than the latter.
After all, that is exactly why we made excavator publicly available.
