Well, I was mining at 330kh/s on my R9 280X at 1160/1500. Using
-I 12 -g 2 -w 256 --thread-concurrency 8192 --lookup-gap 2
Now having reduced intensity to 11 I'm only getting 80kh/s. That about right?
Does anyone know where I can get a scrypt-jane miner with X-intensity or even raw intensity settings? I keep looking but I haven't found anything yet.
Cheers
As I was updating my mining scripts and profitability calculations I stumbled on UTC and ended up with the same problem I was having with CACH, fortunately they're either more helpful in that thread, or they've been on a higher n factor for longer, so settings were easy to get from there, and made a WORLD of difference when I tried the same settings for CACH mining -
R9 280x -
-I 12 -w 256 -g 2 --thread-concurrency 16384
Got me up to about 136 kh/s per 280x from the 75 or 80 or so I was getting when I was fumbling around with settings myself.
Thanks for the help, got both my cards to 137~141kh/s now. I've had to turn my GPU clocks down a fair bit too, had been running 1140MHz on one and 1160MHz on another, but both are down to 1040~1050MHz.
