good morning all,
i have a 2pac when i plug it in my hw start counting thats the only thing it do.
i try to run it solo and with my other sticks but it only makes hw cgminer says my speed is around 300 ghz?.

I bought this 2.1A per port hub > https://www.aliexpress.com/item/10-Port-USB-HUB-Charger-Sipolar-A-400-Standard-20V-6A-Power-adapter/32513481750.html
I have 3 2PACs running on it at 212.5MHz and also have the Pi3 and a power supply fan attached to it to cool down the 2PACs.
It's been running for a week now without the constant stopping of the miners or freezing of the Pi.
As it is a general usage hub it's usefull for anything so not a mining aim only purchase if you might stop mining later.

Hi thanks for your help ... I sort of follow the instructions.
I set in the console frequency 100 (in bash write ./cgminer -2pac -freq 100 et ... ) , starts at 100, then goes back to 75, weird
My Pi only seems t be able to run 2 2pac, I assume my powered hub is not good enough
0 and 1 running at 75 mhz , and 2 is OFF . if I enable 2 , it will just run at 0.
welcome to the club
I've put a text file on the raspbian desktop with the lines below in it.
I just need to open it and copy paste the first 2 lines in the console to run it and that sudo leafpad one to edit the config
cd ./mining/2pac/cgminer
sudo ./cgminer
#edit settings
sudo leafpad /root/.cgminer/cgminer.conf
#show devices
./cgminer -n
#run miner at specific freq
./cgminer --gekko-2pac-freq 150

Usually set to around half a dozen shares sent to the pool per minute so the pool knows you're still connected and active, but not enough to appear spammy.
So I better increase it to 128 or 256 to drop traffic to the pool?

when setting up my cgminer/ linux raspberry pi , I changed frequency to 75 (1st time I started to use my 2PAC, as did not have a fan). It now seems stuck on 75 frequency (a bit low). In terminal I put in start up command and added 100 at end to change frequency : cgminer starts , says working at 100, but then says changing to 75 (again). I can't find the config file (I assume this is where I would have to change). Thanks for your help. NB I am just starting in mining and have limited linux knowledge.
indeed Sidehack,
I think my 2A phone charger power supply ain't stable enough but it's hard to find powered hubs in Belgium that deliver full power to each port and not the standard 0.5A.
I went back to 150MHz as I figured out this night that it stopped mining again after a while and I could not get it working again at 200, 180 either as it stopped after seconds/minutes again.
Now it worked fine through the night at 150.
this is my current stats
0: BSD 10015542: BM1384:2 150.00MHz HW:0 | 21.28G / 16.36Gh/s WU:228.5/m
Thanks for adding the leds, it's not only cool looking but it notifies me when something is wrong if it doesn't flash after a few seconds.

I don't know the technical part of it but when you go from prefered diff 32 to 128 the 'solve' time is 4x as long?
would that time be the same as 4 block solves of diff 32?
or is there no real relation between those?
so what is the prefered diff?
that 10.000 took ages of no output so it looked stalled but is it better in the end than the small ones?

Has zero effect on your hashing hardware. All this does is lower the pool traffic. You don't send lower-value shares, but the shares you do send are weighted higher to make up the difference in your payout calculations. If you set the number too low, the pool automatically increases it to mitigate traffic. Usually set to around half a dozen shares sent to the pool per minute so the pool knows you're still connected and active, but not enough to appear spammy.

currently have 1 2PAC , with 2 more arriving soon. I mine CKPOOL + ANTPOOL BTC , balance strategy. I figure earning some pennies in BTC, whilst playing lottery solo (but pooled) in CKPOOL.
I don't know how I saw over it but a search for "2pac pool" lead to the first post of this thread mentioning ckpool, I moved to this pool now.

I set it to 64 and it's accepting nearly every second.
thanks, j
thanks, j
With suggested diff of 128, three 2pac running at 212.25 get accepteds ~ 6/minute.

I spotted that the difficulty was set to 10.000.
If I change it to 32 the "accepted..." passes by nearly constantly.
Now I was wondering what the optimial difficulty is for a 2PAC running around near 25GH/s.
And do I need to multiply it by 3 since I have 3 2PACs or is this the same for each device?
Edit: I just noticed it went up to 39 automaticaly?

You could easily bump that 32 up, I would probably double it and set it to start with a suggest-diff of 64. Then, if you see the pool continue to raise that, that's a good indication it can, and probably should be higher.

thanks jsays,
I also asked on their irc channel and they adviced to give the solo mining a try since it's always a lottery like you wrote.
For some reason I only saw this "accepted..." passing by once and then 40 minutes nothing.

Am I better on a low crowd pool than this overcrowded one with 200.000+ workers?
Is there one for the 'monoPac', 2Pac, Pod owners?

CK's pool is great choice...but for a couple 2pacs you may want to consider his solo pool. It'd be more lottery-ish for you though, as you'd only get paid if you find the block.

I got my Sipolar powered hub a few days ago.
At first it only seemed to work with 2 2PACs as one of the first 2 dropped out when adding the 3rd one but now all 3 of them seem to work at equal speed (225MHz 24.5GH/s 334.5WU)
Interesting fact is that Slushpool shows 79 years and 2 months to reach that 0.1 bitcoin payout limit
I thought it showed way lower when I only had 1 stick running tho so I'm kind of confused about this 'guess'.

sidehack could design and build a usb hub that is powerful enough to run the 2pacs at the highest speed.
July 10, 2018, 04:54:34 AM
I think he's saying it's good enough to have 10 running and quite fast (and not the stock 100MHz speed)
a lot of the (cheaper) 'powered' usb hubs can barely give enough power to have 2 2Pacs running.
