I'm trying to add another card to my rig and when doing so, the system becomes unstable and eventually crashes.  Consequently, I suspect that I may be drawing too much power from my power supply.  I have a Corsair AX1200 80+ Gold power supply; it has one 100.4A rail.  Under full load, this power supply is rated to be about 88% efficient.

When I measure power consumption at the wall, I read about 1050W.  What does this number represent?  Is it the power draw of the power supply, after which 924W are provided to the system?  Or is it the actual consumption of the system after taking into consideration its efficiency (1050 / 88% = 1193W)?

I would like to run the Phoenix python script directly and test if there is any performance benefit to doing so.  After installing Python 3.2 for Windows 7 x64, I run the following commands in the source directory containing phoenix.py and always get the same error:

Code:

C:\users\me\downloads\phoenix-1.50\src>.\phoenix.py
  File "C:\users\me\downloads\phoenix-1.50\src\src\phoenix.py", line 98
    except ValueError, e:

Code:

C:\users\me\downloads\phoenix-1.50\src>.\phoenix.py -u http://user:pass@uswest.btcguild.com:8332 -k phatk
  File "C:\users\me\downloads\phoenix-1.50\src\src\phoenix.py", line 98
    except ValueError, e:

Line 98 implies a connection error from the following source.  Do I need to pass the url in a special manner on the command line?

Code:

    def makeConnection(self, requester):
        if not self.connection:
            try:
                self.connection = minerutil.openURL(self.url, requester)
            except ValueError, e:
                print(e)
                exit()
        return self.connection

Hello,

I would like to set up an overclocking profile for my 4x6770 machine during Windows start-up; that is, after windows boots and before any user logs in.  Ideally, I would like to set the clock, memory, voltage, and fan speeds prior to running any miners during at start-up time.  Unfortunately, I cannot find a tool that will reliably do this for me.

• ClockTweak is ideal, except the current version doesn't allow me to control the fans for the 6770
• MSI Afterburner would work except that it needs an interactive logon session to apply a profile
• AMD Vision Control Center would also work but also needs an interactive logon session

Is there a tool can run as either a Windows service or startup script that will execute an overclocking profile for the entire machine?
