Here's my .conf:
{
"pools" : [
{
"url" : "stratum.btcguild.com:3333",
"user" : "username",
"pass" : "x"
}
],
"failover-only" : true,
"klondike-options" : "350,55"
}
350 refers to the MHz and 55 to the max temp before it pauses to cool down. I plan on changing my max temp to 65 this weekend, but to get it into the 60s you need to compile cgminer yourself after editing it.
