So I have a 7850 that I've been mining scrypt coins with fairly consistently. I have two "setups", one is at intensity 13 w/ clocks of 980/1350 for when I'm using the computer and the other is intensity 17 w/ clocks of 1050/1350 for when I'm not. I usually get about 270-280 Kh/s with the first setup and 350-360 Kh/s with the second.
Here is my conf file for the first setup:
{
"pools" : [
{
"url" : "x",
"user" : "x",
"pass" : "x"
},
{
"url" : "x",
"user" : "x",
"pass" : "x"
}
]
,
"intensity" : "13",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "2",
"shaders" : "1024",
"thread-concurrency" : "8192",
"gpu-engine" : "980",
"gpu-fan" : "42",
"gpu-memclock" : "1350",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "85",
"temp-overheat" : "75",
"temp-target" : "63",
"api-port" : "4028",
"expiry" : "30",
"failover-only" : true,
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "30",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}
Everything is the same for the second setup except the intensity and clocks.
Starting about today though, I've been getting much lower hash rates with my intensity 13 setup, around 200 Kh/s. Another problem that popped up today was that it started randomly dropping down to ~20 Kh/s and the only way to fix that was to change the thread concurrency to 8192 (I had it at 12288 before).
