Two Sapphire 7850s, which in cgminer and bfgminer mining scrypt give pretty much identical results (been running them since August).
Running vertminer with the settings below, one card gives about 6Kh/sec, the other gives 170 or so. From what I've read, 170 is about what I should expect... so why is the other card doing almost nothing?
I'm using the .conf file, and here are the relevant settings:
"lookup-gap" : "2",
"expiry" : "30",
"scan-time" : "5",
"shares" : "0",
"gpu-threads" : "2",
"gpu-dyninterval" : "7",
"gpu-engine" : "1050",
"gpu-fan" : "0-85",
"gpu-platform" : "0",
"gpu-memclock" : "0",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"intensity" : "12",
"temp-target" : "75",
"temp-overheat" : "85",
"temp-cutoff" : "95",
"temp-hysteresis" : "3",
"vectors" : "1",
"worksize" : "64",
"thread-concurrency" : "6400",
All suggestions appreciated.
