Title: 不少朋友用7970显卡挖矿,cgminer.conf供参考研究,很稳定,运行几周不出问题

GPU核心频率一般在925~1000mhz,会自动调节。挖矿效率在550~600m左右,貌似和天气温度有关,天气凉快效率高,GPU温度在75~82,风扇负荷在70%左右,也能自动调节。

我的這樣跑一個月了,也沒當掉過
7970的話 大概會在 680mh ~ 720mh左右
"intensity" : "9",
"gpu-engine" : "1180",
"gpu-fan" : "0-90",         
"gpu-memclock" : "1000",
"gpu-powertune" : "20",
"temp-cutoff" : "95",
"temp-overheat" : "90",
"temp-target" : "80",


同樣的設定放在 7850的話 大概會在 320mh ~ 350mh左右
"intensity" : "9",
"gpu-engine" : "1150",
"gpu-fan" : "0-90",         
"gpu-memclock" : "1000",

"temp-overheat" : "90",
"temp-target" : "80",

"gpu-memclock" 是用的"75", 但这个你可以试着调到更高,记得过去调到过1000多,印象是温度升高很快,主机重启了,后来调到比较低的数字,发现效率不会有下降,也比较稳定。另外:75的时候GPU Caps Viewer显示的 Current clock mem并不会是75,是在变化之中,似乎这个数字不会起决定性作用,但是太高会有不利。

谢谢分享!maybe my 7970还有潜力可挖啊,我用的是盈通卡,gpu-engine调到过1250,效率也达到过700mh多,GPU温度到了90多,风扇到一下了90%多噪音大得吓人,担心挂掉就给调低了,现在是自适应的gpu-engine频率,设定一定的GPU温度和风扇速度百分比。
