I created 14.6 bins for people running 14.4 drivers on their miner.
On my R9 280X this boosts the 14.4 from 2.12mh/s to 2.48mh/s per card.
1150/1500 1.200mV
Enjoy.
My Gigabyte Radeon 280x had 1.7mh/s and after you bin it went to 1.9mh/s. Its still pretty low. Settings: -g 2 -w 256 -I 18 --thread-concurrency=8192 --gpu-engine=1090 --gpu-memclock=1300
My 5870 rig doesn't seem to work. The miner hashes but gets no accepted work with hw errors. Its funny that 7870 right (same kind) works fine giving 640mh/s per card. Using 14.4 cata. Any ideas?
Make sure you use the newer bin I posted and add "hamsi-expand-big 1" (credit goes to Bullus for hamsi tip)
