Apologies to be a pain, but if I were wanting to mine Yacoin or Microcoin which release [date?] would be the best and possibly what settings for an evga gtx580 ?
grab the stable release 2014-02-04 ...
scrypt-jane with N factors 12 and above should use lower letter kernel denominations. In your case the f (fermi) Kernel. just autotune, and try some various lookup gap values, starting at -L 1 and working yourself upwards...
maybe someone else can weigh in on Microcoin...
Thank you very much for the response and help, very much appreciate all your efforts!
