Got a single HW on a 280x
vertminer.exe --scrypt-vert -o stratum+tcp://gpu.suprnova.cc:4444 -u xxxx -p xxx -I 12 --lookup-gap 2 -w 256 --gpu-engine 1050 --gpu-memclock 1500 --thread-concurrency 4092 -g 2
232khash out of each, good?
You want to use I 13 and tc 8193. You should be getting over 350kh. You may have to adjust your gpu clock speed.
Getting massive HW when I do that.
