I'm not programming, I use the regular ati drivers. So if I don't program my own drivers, I'll not need SDK library, because the Catalysts will do the job for me to put the openCL working on the right maner, right?
My problem is that I've been studying everything that I find about scrypt mining, because I just CAN'T put my Powercolor HD7990 to work properly for mining
I only have 1.1Mh/s with it (550kh/s each GPU) and the best memory/engine factor that I've found was really 900mhz (engine) 1775mhz (memory), and yes I've tryed about 1000000 possibilities step by step.
I've formated my computer and even tryed it on another computer
My settings on cgminer bat file are:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_US_SYNC_OBJECTS 1
cgminer.exe -o pool:9108 --scrypt -u user.2 -p x -I 13 -w 256 -g 2 --lookup-gap 2 --thread-concurrency 14336 --gpu-engine 900 --gpu-memclock 1750
Can anyone help me try to figure out why the hell I can't achieve the at least 1.3Mh/s?
And those settings are the only that can make me have 1.1Mh/s, because with other settings that I tryed, it can go down to 1Mh/s to 950kh/s...
Help will be really apreciated!
Best regards and merry christmas
