I recently picked up an Asus HD 7870 and have been mining with CGminer but no matter what I do I cannot get over 311Kh/s without losing major stability.
this is my .bat file command
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://www.xxx.zz:1234 -u me.1 -p x -I 13 -g 1 -w 256 --gpu-engine 1010 --gpu-memclock 1350 --lookup-gap 2 --gpu-powertune 20 --auto-fan --temp-target 72
I have found that if I go any higher or lower on my engine that I lose hashrate and if I go much higher than 1375 on memclock I lose long term stability.
Help?
System info. AMD 6200, Asus AM3+ mobo, 8gig 1333 ram, Antec 80+ 650W psu, Asus HD7870
Oh, and yes, I am new to mining
