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...
You need 13.xx drivers, I think.
I'm using 14.6 now. I'll try to check those drivers later tonight. Hope I can get rid of those HW errors. Thanks for the help guys.. Much appreciated and btw more thanks to Wolf0 neoscrypt kernel

No wonder you have HW errors. 14.6 is only good for X11. I got <200 KHs with my 280x instead of 350 on 14.6 with lots of HW errors and random vertminer crashes. 14.9 is even worse. Vertminer was not able to change anything on the card on that version (core, ram freq, etc).
14.4 is rock solid, though (at least for me).
