Try these settings:

--scrypt -I 20 -g 1 -w 256 --thread-concurrency 24500 --auto-fan --auto-gpu --gpu-engine 1025 --gpu-memclock 1500 --gpu-powertune 20

my friend has a sapphire r9 290 in but its only getting 558kh

no errors,  but isnt this card supposed to do 750-800kh??

here are the settings

using the newest multiminer

--scrypt -I 13 -g 2 -w 256 --thread-concurrency 8192 --auto-fan --auto-gpu --gpu-engine 1070 --gpu-memclock 1400

what is doing wrong?  if i try to push the I to 14  i get 100% errors


help me obi wai, your my only hope




increase your -i to -i 20 and see what happens.. if card heats up then lower some. 1 -13 is too low. 1 -15 should be ur minimum. what i think anyways from messing around with my two R9 290x's .

R9 290 uses 1 gpu thread, so: -g1 and --thread-concurrency 20481 (although this value will vary depending on how much RAM you system has), after you change both of these you should be able to increase -i and not see any hw errors.
After that, play around with your core clock and mem clock speeds.
