Good day to all,
I'm new with Scrypt-N and looking for a much stable tool. I've tried the vertminer 0.5.3 and sgminer 5 but having some HW errors. Any help with the configurations of R9 270X GPU? Thanks in advance

I think you might want older drivers for vertminer (I used thekev miner with 13.12 (old) drivers), and newer drivers for sgminer 5. Someone correct me if I'm wrong please...
13.12 is decent but 14.4 is way more stable. I use 0.5.3 but I can provide you all the miners I have if needed.
Please let me know.
