gt - I'm guessing it has a lot to do with that the miner's only detecting six chips.

Ok, but across all my Gekko Devices I have been getting 6Th+ and the pool is only showing about 2.5Th.

Ok so heres an oddball problem. Came home today to check on my Gekko Desk toys and noticed that my R606 wasn’t flashing. Looked at my Raspi4 desktop at the cgminer terminal and the R606 had stopped. Restarted it and it would sit at around 700m (previously 775m on Voltage 5) when its set to 900m.

Ran for an hour and would drop out again. Restarted and bumped the voltage to max. Ran for about an hour and settled at 675m then dropped out again. Restarted it again, switched the USB cable to its own port on the Pi (previously plugged into GekkoHub) dropped the voltage to 6 and it got to 787m then plateaued and ran for a bit and then dropped out once again. Took the newpacs with it but they recovered as normal.

I have just restarted it once more and lowered the target freq to 800 at Voltage 6 to see what happens.

The system has been running fine since the end of February when I first got it and found its “happy place”. Nothing has changed with the Pi and there has been no dropouts in power. Room temps peak at 22c (most of the time its cooler).

Could anyone shed any light on what could possibly be happening?

I am still getting the "(Too low difficulty)" message after trying several other pools.

Do i need to set the difficulty to something higher than the "Diff:14.7T" that is currently showing in the cgminer terminal?

"Too low difficulty" is a message from the pool to the miner indicating that the miner submitted a hash which did not meet the minimum threshold of acceptance set by the pool for that specific worker at that specific time.

Some pools constantly adjust the minimum setting to control your slice of their bandwidth while other pools just set a certain minimum(say 4081) to connect to the pool initially then allow your worker to adjust to a lower setting(like 416) that's appropriate for the device. This helps filter out CPU and GPU miners which just can't really cut it anymore.

The miner needs to restart "work" if the setting changes at the pool. Before it resets, it will continue to submit whatever is valid because at the time the hash calculated is considered valid by the miner. Remember your device may have 1,2,16 ASIC chips but each chip has hundreds of cores, each core is trying to solve and submit a hash of the same equation until its instructed something new. Your terminal can't show you everything, its more of a rolling summary, different levels of logging can be used to see a deeper analysis of events.

its a long one, but with the 12 unit plugged in can you tell me what the output from this powershell command is?

Code:

Changing diff to higher than required to find a block doesn't sound like a good idea.

Any decent pool has the ability to adjust miner difficulty to around 18 shares per minute. So you don't need to mess with it yourself.

are you receiving a specific error from cgminer or does the computer just not detect the 8th unit?

Thank you for replay 419mining, love your online store and ebay

. As soon as i plug the 8th newpac this is what keeps repeating. As soon as i unplug the 8th newpac it goes back to running normally.

Code:

USB init, open device failed, err -12,
You need to install a WinUSB driver for - GSH device1:23
And associate - GSH device 1:23 with WinUSB using zadig
See README.txt file included for help
GekkoScience detect (1:23) failed to initialise (incorrect device?), reset

So I am new to bitcoin mining so bear with me on this.

You didn't say what instructions you used to install CGMiner. So here is a link to detailed instructions to review to see if you missed anything.

https://bitcointalksearch.org/topic/m.50968875

Also try with just one stick. After you get one working add the others one at a time. You may have a power issue on your hub.

That's my .02BTC worth of suggestions.

Edit:

I have a raspberrypi 4 that I have connected to a powered USB hub with 7 2pac usb miners.

I just noticed that you have 2pac's. They have a separate thread from the R606's. Not sure how different they are but you should post in that thread.

So I am new to bitcoin mining so bear with me on this.

I have a raspberrypi 4 that I have connected to a powered USB hub with 7 2pac usb miners. The problem that I am having is that from what I can tell is that the pi reconises that the miners are plugged into it but it doesn't know what they are. I've tried this code

Code:

cd ~/git/vthoang/cgminer/
sudo usermod -G plugdev -a `whoami` sudo cp 01-cgminer.rules /etc/udev/rules.d/
sudo reboot

but it doesn't change anything all keep getting is

Code:

pi@raspberrypi:~/mining/2pac/cgminer $ ./cgminer -n

If anyone knows something to fix this either updating the miners themselves or whatever but any help or lead would be appreciated.

Have you tried putting it back on the Pi that it was working on prior to moving to the PC? If it still acts the same way, I would reach out to the reseller you purchased the unit from, they would be able to assist you further.

The NewPac did never run on the Pi, just the first time on the PC as mentioned above.

Thanks again for the replies, you guys help is really appreciated!

I think something got mixed up here. I do only own ONE NewPac ASIC stick, not two. Maybe i was a bit unclear about that.

I tried uninstalling and reinstalling with computerrestarts after every step. -> same error as before
Also i tried to run cgminer on a different laptop (also win10) which gave the same error pattern.

Windows shows that the driver works correctly after installation using zadig.

Any other suggestions?

Thanks everyone for your suggestions. What would you recommend as some good fans? I am thinking of these, perhaps 2? I am not very sure if they will push enough air but noticed everyone says they are dead silent. Thanks.

https://www.amazon.com/ARCTIC-Breeze-Mobile-Flexible-Portable/dp/B003XN24GY

they work fine for a few newpacs, anything around 5 or more i would get a top down fan that moves more air (12v high flow). we have a few options on our website.

Also, https://www.ebay.com/itm/254154810314. its a little cheaper and we ship a lot faster than Amazon right now.

Hurricandave is right, if they worked prior to moving to the pc, its more than likely an issue with the pc, not the miners, especially if they are both acting that way. If your running a single newpac, yes, that hub should be sufficient. Make sure rerun zadig on the pc, verify they are using the WinUSB driver and not "FTDIBUS" that they default to.

You removed the devices from the Laptop then reintroduced them. Verify the driver is working correctly in the "device" properties. Windows tends to ignore/forget what you told it and doesn't always tell you it changed its mind about your instructions and blocked/stopped something critical to your desires.

Just 2 more from me. Try adding a lower difficulty? --suggest-diff 128 --gekko-lowboost

And try a different pool to see if it is pool related.

Hey, thanks for your suggestions vickersja. Tried Both but it did not make any difference.

Quote from: 419mining on April 04, 2020, 05:55:16 PM

Hey bassrelic,

i noticed your hub only has a 5V3A power supply

"【USB 3.0 hub power supply】 - The 5V / 3A wall charger supplies the USB hub"
at 3A, that would not provide enough power to run multiple miners, have you tried running a single USB miner at a time and see how they work then?

Hi 419mining and thanks for the observation and the remark. I am Aware of that. I just wanted to get to know how to mine in the first place and just picked up a not so sophisticated hub which i can also use comfortably for other things. Also i only own one NewPac miner atm - thus i think the hub specs should be sufficient (?)

I am starting to think that the ASICs could be gone for some reason. I set everything up for 100MHz (Without active cooling). I read online that this should be fine but above active cooling is adviced. Is it possible that the IC's suffered heat damages within 1-2 hours at room temp? (21°C / 69,8°F).

Just out of curiosity, are you running them on windows 10? I couldn't get them to stop auto tuning down.

i did, but was not satisfied with stability and could not run Asic Boost at all. So tried linux setup (Lubuntu 16.04). From that moment on mining was stable (with same mining hardware) and Asic Boost was possible.

See my remarks about this subject around page 65 of this thread. I do recommend to use a linux setup.
