I'm using bfgminer on my little single and the temps that are shown shows room for progress "(30c/60c)".  I'm running windows 7 with a little single. This is what I got in the config file. It's basically vanilla or literally vanilla.  I took out the pools and username and pass for security. What temps can the little single run at? Where do I modify and how high.


 
Code:
{
"pools" : [
{
"url" : "http://url1:8332",
"user" : "user1",
"pass" : "pass1"
},
{
"url" : "http://url2:8344",
"pool-proxy" : "socks5://127.0.0.1:1080",
"user" : "user2",
"pass" : "pass2"
},
{
"url" : "http://url3:8332",
"user" : "user3",
"pass" : "pass3"
}
],

"intensity" : "d,9,9,9",
"gpu-engine" : "0-985,0-950,0-960,0-1000",
"gpu-fan" : "0-85,0-85,0-85,0-85",
"gpu-memclock" : "860,825,835,875",
"gpu-powertune" : "20,20,20,20",
"temp-cutoff" : "95,95,95,95",
"temp-overheat" : "85,85,85,85",
"temp-target" : "75,75,75,75",

"auto-fan" : true,
"auto-gpu" : true,
"expiry" : 120,
"failover-only" : true,
"gpu-threads" : 2,
"log" : 5,
"queue" : 1,
"scan-time" : 60,
"temp-hysteresis" : 3,

"scan-serial" : [
"/dev/ttyUSB0",
"/dev/ttyUSB1",
"/dev/ttyUSB2",
"/dev/ttyUSB3"
],

"kernel-path" : "/usr/local/bin"
}

These aren't modified through BFGMiner, the throttling and clockspeed is controlled in firmware. Short of modifying the firmware and flashing it to the unit using JTAG it probably isn't that easy. You might have some luck asking on the BFL forums however...

Probably should put something here.... Maybe an LTC address?

Are you sure it's done via Jtag? What a pain in the ass Cry

Yes. It is done in the firmware. There's a threshold for the temperature of overheating and the engine will restart if it overheats... Check out the source codes  Wink

Painful indeed, but not so hard if you have a Raspberry Pi lying around... :-)
