yeah.
I am using the CCMINER spmod for nvidia....
latest version..
using this string: ccminer.exe -r 0 -a myr-gr -i 17.5 -o stratum+tcp://mine.zpool.ca:5433 -u 1PHSDYvVp6HpqtuUPocK41DrdeHbbezaeP -p d=0.4,myr-gr=49.5
(cuts out confusion)
I don't see anyone mining myr-gr with the SP_MOD fork of ccminer so it's probably broken. You should probably report it
in his thread.
The TPruvot fork 1.7-dev seems to work.
