Nobody will know why it doesn't work without a lot more information. Did you grab one of the gekko-specific cgminer builds linked to in the first post? Is your USB port totally weak (for reference, 150MHz will ask for about 1.2A)? What cgminer output are you seeing?

well- ok- yeah noob and didnt know exactly what one would need to diagnosis - thank you for getting back in touch ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) but i will answer best i can- so yes i tried the cg miner that was in the start up package writing that came with it and installed the drivers as instructed. I have tried it in a usb port 2.0 and 3.0 - same unfavorable results all i get is like this quick flash of a dos window and poof gone- split second _____ so i tried in my buddies pool - to mine zetacoin- to see if maybe i could it run with that https://hobbyistpool.ddns.net/zet/index.phpand followed those instructions to a t with the bfg miner link he gave - nothing except for a dos screen that at top reflects the line of code that was to be written and saved as a bat file - server, username, password, etc - that stuff

If your terminal opens and immediately closes it's because something threw an error. You need to find out what that error is.
I don't believe there is BFG support for the 2Pac.
If zetacoin isn't SHA256 you can't mine it with the 2Pac.
You should probably also talk to the person you bought the stick from. That guy took your money so he owes you a bit of service.

I've been trying to find a way to get my miner running, but when I run cgminer it sits in zombie mode with:
GSD 0: 2Pac BM1384 Bitcoin Miner (1002****) GSD 0: found 0 chip(s)
Other times it sits at 0 h/s with: 0: GSD 1002***: BM1384:2 100.00MHz HW:0 | 0.000 / 0.000h/s WU:0.0/m
I tried on mac, windows and on a raspberry pi. I also tried connecting directly and using a powered usb hub.
Any ideas ?

Did you ask advice from the guy you bought it from?

I bought three 2pacs last week {...}
Two of the three work great, but the third consistently shows in cgminer as 0 chips found.
I've read and run through all the suggested steps in the forum here, but thought I'd reach out and see whether there was anything else you'd suggest I'd try.
Most of the notes seem to suggest that the RC buck is tripped.
So far, I've tried... -Solo, plugged directly into a motherboard as well as on a powered hub. -Adjusting the voltage up ever so slightly (1/8) turn and (1/4) turn, from the initial 7:00-ish position. -Set cgminer to 25MHz, unplugged waited a few seconds and then re-connected.
...all with no luck
Lastly, I picked up a new multimeter today {...} and found that both chips are showing right around 300mV (both seem to read about the same, but vary slightly between 295~320mV depending on the port I plug it into).
Please, any advice/suggestions to try? I tried emailing back to the sales@ address I'd used to buy these originally, but haven't heard anything there after a few days now.

Hi!
GEKKO 2PAC / Linux 16.4 / cgminer 4.10.0 / HUB 2.0- 2A / FAN
How to underclock correctly?
My device works fine until 25M.
Under 25M, the device become "disabled" after few minutes.
Enabled or reset it, in option menu, has no effect. Only manual unplug/plug can restart it correctly.
_______
If possible how to start immediately at the right frequency? Calibration of 100M up to the desired frequency is really bad..
Thanks.
EDIT.: Received today a second Gekko and tested ok at minimal freq. Means there is a hardware problem with the first Gekko.

Why are you trying to let it run below 100 MHz? 100 MHz should run fine. What position is the voltage pot looking at it on the electronics side with the usb port facing down? Should be at about 2 or 3 o`clock.

There is no potentiometer on the Gekko 2PAC PCB (top or bottom).

Thanks for answer. As i have 2 Gekko (same PCB), i could compare. There is a difference of 1 resistance (9 Ohms) between them. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi62.servimg.com%2Fu%2Ff62%2F19%2F28%2F27%2F85%2Fgekko10.jpg&t=665&c=fUfsGEJaGQQOAA)

That fix helps stabilize imbalanced voltages that prevent the chip string from lighting up properly at low voltages.
Those are black bitshopper sticks. Are you in Europe?

And in the upper right edge of both sticks you see the pot. But it seems to be set to a good position. Looks like 2 o´clock. So it should run fine at 100 MHz.

Hey guys hope you can help me
i have this settings cgminer.exe -o stratum+tcp://stratum.803mine.com:3339 -u xxxxxxxxxxxxxxxxxxxxxxxxxxx -p x --suggest-diff 32 --gekko-compac-freq 200 but i have still 100 MhZ. I have 2x 2pac´s and i want the maximum ;-)

I believe you'll want to use the explicit 2PAC frequency flag, not the compaq version. Remove: --gekko-compac-freq 200 Add: --gekko-2pac-freq 200 So, something like: cgminer.exe -o stratum+tcp://stratum.803mine.com:3339 -u xxxxxxxxxxxxxxxxxxxxxxxxxxx -p x --suggest-diff 32 --gekko-2pac-freq 200 Also, make sure you're running a fan on them at that frequency, as they will heat up significantly more than at 100MHz.

Hey ty jsays but i try this too and nothing :-( how can i put a picture in there ?
One other thought, verify whether you have a cgminer.conf file in that directory. If you do I have found that it will take any frequency settings in there over any added at the command line. So, either update that file, or rename it to something else, such that it's not used. Good luck!

Hello guys, I just received my first unit and am trying to get it going, I seem to have the driver right, the mining software recognises the gekko science usb but is says <4:2> "failed to initiate" and something about incorrect device but it's partially cut of so I can't see it. then it says "failed usb-init" and "waiting for work"
it sits like that for about a minute then shuts off?
I read the readme file but I think I'm stuck, bad pool? any help would be appreciated
Edit: I think I initially messed up by installing the zadig drivers without a device listed (I couldn't see any devices) it said it worked, then I finally figured out how to see all connected devices clicked the gekkoscience device , installed the drivers again this time to the device.
I got it working on my windows 10 machine just fine after my first try, it's my windows 7 machine that I'm having the issue on
