GekkoScience 2Pac/Compac BM1384 Stickminer Official Support Thread

[irritant]

could be the rpi is getting old?
I have the same with two old pis, one dies after one day, another dies after about a week, tried installing cgminer on my diskstation, it worked and it sees the sticks but hashing didnt work, im now running it on a linux server
I'll check later (when i get a fresh rpi) if they indeed were getting old

hi.

i can't seem to get more than two of these going at the same time in cgminer.  by default it should use all the devices i think.  i've tried specifying the devices using --usb but that didn't work.  i'm using the same cgminer pulled from git in the first message.  when started with the command line below it recognizes all my gekkos:

-o stratum+tcp://us1.bitminter.com:3333 -u username -p x --gekko-2pac-freq 200 --gekko-compac-freq 200 --suggest-diff 3 

Code:

however notice above it only opens GSD 1 and 2.  when hashing only those two devices do any work:

when i ctrl-c the cgminer process, it also shows two devices were unused:

how to i get cgminer to use my other two gekkos?

thanks for any help.

I'm gonna guess your hub sucks. Unless it's the same stick not working every time, in which case you might consider turning up the voltage. I'd read the most recent 5-10 pages in this thread because similar issues have come up at least once or twice lately, with discussions about diagnosing the issue.

[der_wasi]

My R PI cannot seem to run for more that 24 hours without freezing. It's running the https://github.com/vthoang/cgminer miner. Once it crashes, I obviously cannot ssh into it. I just cycle the power on it and restart the miner program. It's kind of annoying.

I find the thermal sink to be warmer than usual. I have tried a fresh install with a nicer SD card, but it didn't help. I also run BFG miner running moonlanders which has never crashed in the weeks I've been running it. Are there other miner programs I could use to run Gekko 2Pacs? Any other ideas to improve the stability would be much appreciated. I have dealt with USB power issues, but I don't think that would cause the RPI to lock up.

Try this:
https://bitcointalk.org/index.php?topic=494625.msg5932931#msg5932931

It helped solving the same issue for me.

hey.   i am using an anker 10 Port 60W USB 3.0 hub like this one below:

https://www.amazon.com/Anker-PowerIQ-Charging-Macbook-Surface/dp/B00VDVCQ84/ref=sr_1_1?ie=UTF8&qid=1519320527&sr=8-1&keywords=Anker+10+Port+60W

i will take your suggestion and do more reading of the thread so i can troubleshoot / diagnose my units.   i did try dropping the clock to 25MHz and had the exact same behavior, it only using GSD 1 and 2 and none of the others..

thanks.

[mrw21j]

What arguments need to be added (if any) to CGMiner for 2 sticks running from the same powered hub on Windows?

When you increase the MHz to 200 did you also increase the voltage with the potentiometer? Did you try with only the 2pac and only the compac? Did you have the sticks right next to each other?

Back in the thread there was talk about getting both to work on the same host but I have not found it again.

[MrWan]

Quick question on expected performance chart.  I've been fine tuning my 2pac sticks and running them at frequency 200 with the knob turned to about 1.6 amps.  The hash rate is currently 21.26 gh/s.  Will the higher than expected performace for hashing cause instability?

[sidehack]

"higher than expected performace for hashing" Please explain.

[MrWan]

Expected performance rate should be around .11 x 175 = 19.25 gh/s but i'm getting around 20.55 gh/s.

I just realized that i had a typo in my last post.  The frequency was set to 175 and not 200.

[der_wasi]

It´s fine. If they do more than expected, great.

[avulsionist]

I just went through and set up a new PI2 and PI3 for testing and wrote down all the steps. What is the best way to share this to the forum?
Inline? A google doc?

I am using cgminer vthoang with minera on rpi and 7 gekko 2pac to try and solo mine Litecoin Cash.

i had it working with btc solo mining even though i know it wont ever pay so please don't go there.

I have everything set up and working for lcc expect i get error since there is no command for lcc-address and lcc address will not resolve as a valid btc address.
do you think if i hit a block i would get a payout with this error.....?

how can i get command for lcc address into cgminer.....?

or any other ideas....?

i also have antminer s7 minning for lcc through a pool for now and making money probably....

So when they forked Litecoin, did they also change the algorithm from SHA256 to Scrypt?

[lok8nusa]

So when they forked Litecoin, did they also change the algorithm from SHA256 to Scrypt?

Litecoin Cash is SHA256. I'm investigating.

[philipma1957]

Yes and they will try to make a weak hashing item like sidehacks sticks and pods mine to a lower

Difficulty.


It is an attempt to bring older gear back to life.

It could add value to the pods and the 2 pacs.

Buysolar got a spondollies sp20 running at a pool.

He said it was earning better then the s9 he pointed at it.

Hello,

Has anyone had an issue with their 2pac going into an "OFF" state after the latest git pull and rebuild of vthoang cgminer on raspbian?
I was running very stable for the last month with auto recovery via systemctl service and a few edits to the cmdline.txt.

I am also having this exact same issue on windows, will set up the log file to see if it captures anything.

Which distribution are you running on your pi, and what kind of power supply are you running the _pi_ with.  I assume you have the 2pacs in a seperate, powered hub (2Pacs NOT plugged into the RPI, but plugged into a hub).

Thanks for the response. The RPI run the latest RASPBIAN STRETCH WITH DESKTOP with Pluggable powered USB

I think the issue is related to the way I'm launching it. I was using Minera for a while, which had the same issue. I was launching vt's cgminer via ssh same way Minera would, like this...

screen -dmS gekko sudo cgminer-vthoang --gekko-2pac-freq 190 -c vt-miner-conf.json

where  vt-miner-conf.json looks like this.

{
    "api-listen": true,
    "api-allow": "W:127.0.0.1",
    "log-file": "\/home\/pi\/cgminer-vthoang.log",
    "pools": [
        {
            "url": "stratum+tcp:\/\/us.multipool.us: 3332",
            "user": "crishouse.tupac",
            "pass": "123"
        }]
}

I have stopped using the -c and instead launch it directly with -o, and it hasn't crashed since.

[haleyma]

Are you passing in --gekko-2pac-freq or gekko-compac-freq? Because these are 2Pacs so they want the 2Pac flag.

Thank you.
I am passing in --gekko-2pac-freq 150, but the pi terminal display says they are working at 100MZ.  I'm okay with that.  Suppose it could be a potentiometer issue, but after I set both sticks with the pots at "flat side at 3'oclock" they are functioning and I don't know if I want to mess with that.
