Yeah i know about those, but i don't want to pay 20$(I'm in Canada) to test around with my 20$ toy. I through i could check the amp with the first and 4th pin, but that didn't work out. And i don't know enough about circuits to guess how to do it without frying stuff.

Get a usb tester: http://www.amazon.com/DROK-Multimeter-Capacity-Charging-Alignment/dp/B00J3JSEG6

I just ordered 4 sets of Y cables so I can really start playing with my sticks.  Highest freq. I can get on hub right now is 262.5 without exceeding the amp rating for each port.

Sadly, i do not see how to measure amperage to figure out what the maximum clock i should set it to with a y-splitter on an USB3.0 hub. I only have a multi meter.

Yes, you can adjust voltage while it is hashing and stop once the HW error stop.  Very nice for real-time feed back rather than having to edit a command line, stop and restart hashing, etc.

Most of the questions anyone could ask in this thread are answered in the first post. Any question that can't be answered in the first post is more than likely either the result of a misunderstanding, misconfiguration or grounds for warranty replacement.

is it safe to turn the knob while the thing is hashing to find the sweet spot?

What points do I measure the voltage?

I plan on doing some OCing soon. On the far left and right pin of the usb connector?

Assuming you turned the voltage up, since that's one of those things you have to do to overclock it?

So the stick has been working well since i received it, however if i try to run it on a hub, it does not get found by cgminer. Reinstalling the zadig drivers or such does not change anything. Is there something else i need to install for the hub to work properly? (Windows 7)

I have other devices on the hub that work at the same time.

Ahh, could be.  I was thinking the leading 0 issue was with the RPC command, I do not recall if I used a leading 0 on the --set as well.  I will confirm tomorrow.

As an aside, the RPC way of adjusting frequency is pretty darn cool since you can do it while they are running.  Couple that with the adjustable voltage, also while running, and you've got real time feedback from a very customizable piece of hardware!

I have no problem getting 15 Gh/s myself.

If you want to run the sticks on linux, you'll need either bfgminer or cgminer.  Either way you are probably going to have to compile them, but I've had little trouble with this so it's probably just a matter of running a few simple commands.

Here's what you'd do to get cgminer on linux going:
1. Open a terminal.
2. wget http://gekkoscience.com/misc/cgminer-gekko.tar.gz            

This downloads the file- you can save it from your browser instead, it's the same thing.

3. tar -xvzf cgminer-gekko.tar.gz

This extracts the files. which are compressed (like a zip file for linux)

4. cd cgminer-gekko
 
Enters the cgminer-gekko folder you just extracted.

5. sudo apt-get install build-essential autoconf automake libtool

You need to install the dependencies for cgminer.

6. ./autogen.sh

This will generate a configure script for you which will set up compiling for your system.

7. ./configure --enable-gekko

This will configure the build.  This is the most likely place to have anything go wrong, if it does, let me know exactly what's up.  Odds are it would be some package that you should have installed.

8. make

Performs the build.  If you get an error there- again, let me know details.

You are ready to run cgminer.  This should look something like:

./cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr --compac-freq 150

Although if you don't have permissions setup you may have to become root or use sudo, eg,

sudo ./cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr --compac-freq 150

cgminer should now detect any compacs plugged in while it is running.  Obviously you'll use a slightly different command to launch cgminer, if you use that one you'll be mining for us!  Most pools even post example commands, let me know if you need help figuring it out.

I assumed that your problem was the extra leading zero... no? :/

Can anyone else with a prod unit confirm/deny a problem?
I can't imagine what would be different.. :|

I was unable to get --set cbm:clock=xNNNN to work.  I believe you said you used it on the pre-production stick that was sent to you, but I cannot duplicate your success on the production stick.
