Hey all. I am running 4x Sapphire Toxic 280x's. I am currently getting 2.388 Mh/s from them each, low temps. Should I be getting more? Config to follow:
--scrypt --Nfmin 4 --Nfmax 30 --StartT 1393167677 -I 20 --thread-concurrency 8192 -g 2 -w 256 --lookup-gap 2 --gpu-memclock 1800,1800,1800,1800 --gpu-engine 1180,1180,1180,1180 --expiry 1 --scan-time 1 --queue 0 --gpu-powertune 20,20,20,20

I tried I=13, 15, 18, 20, all of them. I have tried changing TC from 8192, to 11200, and a couple others. Also tried Mem clock from 1500-1800, changing it slightly each time, and finally gpu engine at 1050, 1070, 1080, 1150, 1160, 1200, 1220, 1230, etc.

I see people saying a lot more, but am I just seeing this due to the N-factor going up? Or should I change settings?
