Thanks Wellenreiter for your guidance.
I found the best cgminer version for my Asus HD7950DU2T, it has to use cgminer 3.3.1 to optimize the card and it running at average of 558kh/s with 65C. i have a big fan blowing my rig.
Below are my cgminer 3.3.1 cgminer.conf settings:
[quote]“intensity” : “18”,
“vectors” : “1”,
“worksize” : “256”,
“lookup-gap” : “2”,
“thread-concurrency” : “22400”,
“shaders” : “1792”,
“gpu-engine” : “1000”,
“gpu-fan” : “40-70”,
“gpu-memclock” : “1500”,
“gpu-powertune” : “15”,
“gpu-vddc” : “1.100”,
“temp-cutoff” : “80”,
“temp-overheat” : “85”,
“temp-target” : “80”,
“api-port” : “4028”,
“expiry” : “120”,
“failover-only” : true,
“gpu-threads” : “1”,
“log” : “5”,
“queue” : “1”,
“scan-time” : “60”,
“temp-hysteresis” : “3”,
“scrypt” : true,
“kernel” : “scrypt”,
“kernel-path” : “/usr/local/bin”[/quote]
after i have make the changes and using the correct cgminer version, i hit a block last night and it pending 77 confirmations before i can get my 200FTC. I’m so lucky!!!
will continue to explore the settings guidance given by bro Wellenreiter to fully optimize my card.
Thanks again for help!!
