hi all
so i just built my first rig.
GPUS - 3 - sapphire 7850's in it, all running on non-powered risers.
PSU - corsair HX 850
MB - ASROCK|970 EXTREME4 AM3+ 970 R with 8gb ram
CPU - AMD Sempron 145 Sargas 2.8GHz
using BAMT 1.1 off a usb stick.


in the bamt.conf file, i set the fan speeds to 70


i was able to put in my miner pool settings and get this running, with these settings for my cgminer.conf file...



"intensity" : "17",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"shaders" : "0",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"gpu-engine" : "1050",
"gpu-memclock" : "1300",
"gpu-powertune" : "0",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"scrypt" : true,
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}




here is what my BAMT screen looks like after about an hour and a half..
1.02 Mh/s


all 3 gpus are showing almost the same readings...
[size=78%]gpu0 -  stratum+tcp:us3.wemineltc.com:3334  temp 65.0c Load 99% Rate 0.34 Mh/s Accept/Invalid 146/2 //Fan 54% Core 1050Mhz Memory 1300mHz Power 1.075v[/size]






i am on a Mac computer so i do not really have the ability to use the windows based "cgEasy" software to find out my best settings..


just wondering if anyone can look at this and tell me what i might want to change to make things run more efficiently or if i have something set wrong..


thanks in advance...
