thanks for help mikeybit, settings you had were really close
seems to be a memory issue with my card, whenever memory is at 1500 it crashes, lowered to 1450/1460 and seems okay there
getting 450kh now with cgminer.exe --scrypt -I 18 -w 256 --thread-concurrency 14208 --gpu-engine 1110 --gpu-memclock 1460
I'm willing to bet if you lowered your gpu-engine you'd get a few more hashes out of it...
ok lower it and up the intensity?
how did you get so good at tweaking these settings btw?
Had to lower intensity and settings for my other card 7770, the positioning in the case makes it sit above the R9 270 and so the 7770 get really hot, above 80c (lowered its intensity to 14 at 74c and get it at 160kh instead of 197kh)
If i get more serious with this I'd like to build those open cases with risers but just playing around for now and still not very good at buy/selling/trading on sites, i usually end up losing profits.
