With a 6 X R7 240 4GB rig, I am getting a total U share rate of 6 shares/m vs 15 shares/m on NFactor 15 (hashrate can be a little misleading).
I only changed the lookup gap from 2 to 3. I don't think I can do much better than that...
I think this will be the most profitable cpu coin once the difficulty adjusts. Is this something someone can confirm?
My I7-3770k was getting 0.82 khash/s before, and now it is getting exactly half at 0.41 khash/s.
My i7 3610 laptop CPU is around 400 H/sec - half of what it was at NF=14. That's no surprise whatsoever. My 2GB R7 250 cards lost quite a bit though and are only twice that of the CPU, but are still using less wattage.
U on R7 240 4GB cards is about 1.1, down from around 2.7 (i think)
R7 250 2GB cards are stinking up the place... U of < 0.7
