yes, use this one https://bitcointalk.org/index.php?topic=2021765.0 it gives you around 3-4% more that ewbf miner on my cards it gives around 770 sol/s per card, this @ 90 pl, +100 core and +250 memory
can confirm, using the same miner and card and getting around 785 sol/s, mine's at +60 core/+560 memory
