Guys this is so much fun!
My 280x is hashing at 670 Mh/s, I think I can go past 1 GH/s :-)
Not even whirlpoolx was so rewarding!
Would really appreciate it if you could share your settings. I am hashing with only about 100-112 Mh/s with my 280x
Modified miner and mostly rewritten opencl code. Still a work in progress. Power use is almost doubled.
