Rrunning 280x MSI Gaming @ 2.25 MH:
"intensity" : "13
"lookup-gap" : "1",
"gpu-threads" : "2",
"gpu-engine" : "1150-1150",
"auto-fan" : true,
"gpu-fan" : "0-85",
"gpu-memclock" : "1500",
"gpu-powertune" : "20",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "80",
"temp-hysteresis" : "3",
"vectors" : "1",
"kernel" : "darkcoin"
I'm running three Sapphire 7970s and can't get them over 1.6 mh each.
Also, sgminer won't load my gpu engine/mem or autofan settings.. neither through a config nor bat
I've tried the same config as you (with different engine settings), as well as many others.
Any ideas?
Check engine clock in miner UI. Sometimes miner can not set correct frequency.
