Anyone tried mining with a 7990? Any good? I have one used for CAD work, but at night.......
I have four 7990:s hashing.Mine are doing around 2200Khs per core / 8800-9000Khs / card.
What miner and config do you use? With scrypt mine liked -I 13 -g 2 -w 256 --thread-concurrency 8192 with cgminer 3.7.2
sgminer -o stratum+tcp://lotterymining.com:4444 --lookup-gap 2 -I 20 -w 512 --thread-concurrency 28500 -u Weblogin.Miner -p Password
I get around 2200Khs/core = 4400-4500Khs / Card
I have pretty high sensity but i hardly get any hw errors. Some cards getting 0.1-0.2%. Trying it out from 13 and up is probably not a bad idea.
