an the other it tries and crash

[16:51:37] Building binary talkcoin-modTongagw256l4ku0.bin
Is your GPU a r9 300 series? 380-380x-390x etc?
Have you latest Crimson driver?
Did you get same errors mining different coins?
hello thanks for help
so 1st computer is ruining a r9 380 last crimson driver
sgminer won't start on vip , but i tried mining skein (dgb) it start but all share are rejected
cgminer with skein works fine
other computer is running r9270 and r9380
it start but crash maybe for 380 ? gonna disable the 380 and test, same driver
so i tiried with the 270
sgminer 5.1.1 crash
sgminer 5.1.0 starts (take long time)
112kh/s for r2 270 without setting
now i added -w 64 -g 2 -I 19 for 5.6mh gonna tune that later
looks like it is using talkcoin-modPitcairngw256l4ku0 for r9 270
so what to do for 380 gpu ?
Try with sph-sgminer talkcoin (not mod version).
R9 380 is Tonga, so don't use sph-sgminer mod version that are based on Thaiti-Hawai (r9 280x etc).
Sometimes they simply don't work properly with Tonga GPU based chipset.
Crimson 16.1 and sdk 3.0 should be fine.
