Yes - LCC is SHA and it's a scam so careful with it.

@crishouse: Did you try this?

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.

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.

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

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.

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.

Litecoin Cash is SHA256. I'm investigating.

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

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....

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?

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

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.

"higher than expected performace for hashing" Please explain.

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?

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.

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

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.

Try this:
https://bitcointalksearch.org/topic/m.5932931

It helped solving the same issue for me.

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.
