you should slowly dial back the power until it doesnt start up and see how low it will go.


one thing at a time.

when the pot was in this  position   +

it was hard to start at freq 150

in the current position  see photo  maybe a ⅛ turn  it starts pretty easy at freq 175

pot is tiny and delicate not looking to turn it much.

If you have a multimeter, you can check the voltage either at the caps along the left edge below the heatsink, or on the test pads on the back of the stick. I believe from top to bottom they are SGND, Vcore, 1.8V (ASIC logic/signals), 0.9V (ASIC PLL) and PGND

I will get to it later today.

so moving from freq 150 to freq 175 jumped .7 watts and added 2.02gh   that is pretty good  .


less then .35 watts a gh.  

lower right corner is adjustment pot   it was like this

+    I turned it clockwise just a bit.

ran it over night .  my pc is acting a bit flakey. it is dedicated to mining so no info is at risk.  I think I picked up some kind of malware loading  down loading zadig.



So today I cranked the little pot  from 12 oclock to 2 oclock and I re set the stick to  freq 175.

the kwatt meter jumped from 5.7-5.9 to 6.6  watts so lets say    a .7 watt jump

and hashing jumped about  2 gh  to 9.81gh

BTW I got cgminer 4.9.0 working not 4.9.1


4.9.2 was just released, it should work with the U3 stuff now (per the changelog, I haven't tried it yet).

The pot in the bottom corner near the USB jack allows the output voltage to adjust between about 550mV to 800mV. I believe turning clockwise increases the voltage. It should have been set to about 610mV when you got it.

not so clear on the pot for  power adjustments.  I will photo close up tomorrow and ask questions.

so far it runs well and is actually cold to the touch. (due to ac  for the house and a fan for the stick)

At 150MHz it should converge to 8.25GH. Good to see no HW errors. You might be able to turn the voltage down a bit and it still run smooth at slightly lower power. Startup currents tend to bounce the voltage a bit so they don't always start at as low a steady-state voltage as they'll run.

At 610mV 150MHz I ran a set for 24 hours in my ~90F shop with no air movement and zero problems. Hopefully with a decent fan and cool ambient it'll go hotter better. The makeshift heatsink on there is a bit bigger than the stock which will be on the final version.

basement is cold 70f and the fan so it will be cool ..  Going to let it run overnight then play with it on fri.

sticks are impressive. 5.9 watts which bounces on kwatt meter  5.6 to 5.9

this includes the entire hub the fan and the stick.

if I unplug the fan kwatt drops to 4.7 to 4.9 watts

so the hub is a 18 dollar junk hub with a junk wallwart 12volt 3 amp rating  I know it wastes power.   so these sticks are easy 3 watt for 7.7gh on a hub using  a platinum atx psu.

Other then zadig driving me fuckng nuts  for hours nice.

cooling is done. there is a 5volt usb fan on the right

note this is pulling 5.9 watts but it does the usb stick the hub and the fan
I will post a cleaner photo of the fan.

Have you worried about "cooling" at all yet? I never ran a stick miner that didn't get pretty warm in dead air.

Good result, regardless of the hashrate.

no it is at 150 I think mmpool was over generous I am running it at btcguild pool now and getting  lower pool side numbers.

7.79gh which is more like it.


BTW I got cgminer 4.9.0 working not 4.9.1



I hate loading zadig.

Got to make it easier for newbies 2 pc's and multiples boots stripping drivers out putting drivers in got to make this easy to help people start it.

CONGRATULATIONS!!!
