Gridseed power usage guide with duel mode and script only mode

Part 6: Power Usage & Temps

 

Power usage is roughly the same when running from Windows, Linux, RPi the new software allows the devices to run in single mode from these platforms as well.Power Usage and Speeds: Power is based on killowatt readings for the controller, USB hub and 10 devices using a Corsair AX1200 PSU.  Divide out the power factor for actual usage.  The speed reports are only based on a 5-10 minute sample time so add +/-10% variance.  You can see in the screen cap that the per device speed is completely crazy this is mostly the controller and device quality.

Power Supply Efficiency: Corsair AX1200 80 Plus GOLD

Disconnected from controller – Fans/Leds, PSU, Controller, HUB
61.2 Watts

SHA only mode.  It’s not even worth testing these in SHA only mode so I have excluded it.

Freq 600 Dual Mode
~2.5Mh/s scrypt (Controller)
~1.5Mh/s scrypt (scryptguild)
~80Gh/s sha (eligius)
429Watt

Freq 700 Dual Mode
~2.75Mh/s scrypt (Controller)
~1.8Mh/s scrypt (scryptguild)
~95Gh/s sha (eligius)
507Watt

Freq 800 Dual Mode
~2.5Mh/s scrypt (Controller)
~3Mh/s scrypt (scryptguild)
~120Gh/s sha (eligius)
583Watt

Freq 850 Dual Mode
~383Kh/s scrypt (Controller)
~383Kh/s scrypt (scryptguild)
~70Gh/s sha (eligius)
627Watt

Not sure where the power went.  900 is even worse so the bulk spot is between 700 and 800 on this set.

Temps were really boring in dual mode.  The massive fan on these take away the heat very well which is new for an ASIC maker.  Ambient 74F-78F Max device core 96F outflow air 86-90F.
