GekkoScience has a new stickminer that does 300+GH

[Powell]

I don't want to quote because the post he made was very long.  It's been awhile and I got help from the guys on here and the ones in the Kano Discord, but adjusting the vCore voltages for whatever reason made everything happy.  I currently have 9 Compac F's running at 500MHz (I am waiting on another batch of Gekko hubs so I have one on a hub that can't do more than 2.0A (if it blips above for more than a second it shuts the port down and resets the stick), but I have all 3 hubs connected via their own USB cable to a single Raspberry PI 4 (8gb version).  

Rasp Pi4 has only 4 usb ports, how do you manage to plug them all in including keyboard & mouse

and i assume you're not running windows, as i tested out 500MHz on windows, the WU sits at 4,4xx/m while yours runs @ 4,6xx/m.
  is it on Linux ?

The vcore voltage adjuster is the little VERY small phillips head looking screw on the bottom right of the PCB if you are looking at the heatsink side.  There is a post somewhere in here talking about adjusting them and how much to.  I went through and did every one of them one at a time.  End result though was all 8 (now 9) working together with no issue

    I will search for the post, thanks.
Also i noticed the V - adjuster has 2 flat ends, while adjusting each of them, did they all end up in the same position ?
If so, what is the position ?

I do not use a keyboard, display or anything on my PI, so all that is connected currently is 3 USB connectors and a CAT5e cable.  I just run a basic installation of Rasbian and have it setup to run headless when I create the SD Card.  I do everything else in PuTTY via SSH.  The hardest part for anyone who is new would be compiling cgminer but there are plenty of tutorials on this forum (and I think even in this post) to get anyone through (including myself).

Each adjuster has it's own position for the most part as originally I tried finding one spot and set everyone of them the same.  Because each ASIC is a tiny bit different due to silicone lottery there isn't a complete one size fits all solution if you are going to push it past the 400MHz that the sticks are originally made for.  You also need to have a USB power draw thing (I don't remember the technical name but it plugs into the USB port and the stick plugs into that) for testing and adjusting voltage because you can end up with way to much power even at 500MHz if you have too much amp wise if you adjust too much on it.  After I finish each stick I just move the next stick onto it.  So you only need 1 of them and they are less than $20 on Amazon.

I think you are going to continue to have problems on a Windows based machine.  Each stick upon receiving them I did run myself on my personal desktop (at the time a AMD 3950x on a Gigabyte Aorus MB, but I used a USB hub that could provide 2.5A so even at 500MHz it would get angry at points).  The PI is a cheap very easy to setup solution and you can just set the sticks up with some kind of cooling solution and forget about them really.  I monitor everything through the default miner.php included in cgminer.

Nice. will look for that. do you have a link to share on amazon for it ?

Would Prolly go that route, hopefully i get sorted out. thanks.
about the miner.php, how do you access it ?

found this on amazon: X-DRAGON Dual USB Digital Power Meter Tester

is that it ?

Yeah, look for 'USB amp meters', but it sounds good. I personally prefer the straight ones, where the miner is plugged in a straight line with the USB ports. That way it fits better onto the hub. But any type should work.

Thanks, I found the type you refer to, in form of a flash drive.

Anyone knows a good Rasp Pi source ? cant find stock online.. Pi 4B 8Gb..

All the good retailers have no stock, one says due in around 14th March here in the UK.

I need help, can anyone share links that can guide through the process for compiling cgminer on rasp OS..

[sidehack]

There's a link in the first post, to a post hanging out on Page 3, with all the instructions you could want.

Thanks. I found the post & was able to setup cgminer just a couple more things...

1.  im not yet able to generate the gekko.config file... still not sure how..
2. when i run the cgminer, it showing GSH errors , cant detect miner which i believe should have been GSF hence looking for the wrong hardware..  how can this be corrected ?

[elsupreme]

By the way, i'm happy to be making these progress. Thanks to everyone who's been helpful even though im not there yet but i know i will ...

Some indication of the output of the screen in [ code ] tags would help, or a screenshot.

Oh yeah that old guy. Error as old as cgminer running USB devices. From the Compac/2Pac support thread:

Q. How to get past "USB init, open device failed" ... "you don't have privilege to access" error.

Code:

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

You'll want to cd into the correct cgminer folder, but that is probably obvious. Either that, or run cgminer as root.

That solved the issue, thanks a bunch. what of the config file ? i will like to input my settings in it ... how do i create  / locate it ..? looked through the cgminer directory looking for gekko.config i imagine but didnot find one ..

The extension for the config file is .conf.

The conf file is a pain in the a--.  I like just using the command line so that I can easily make changes when I want to try something different.

But each to their own.  Just don't forget you started using the stupid thing because it overrides your command line when you try using it.

[sidehack]

Yeah I never use a config file, just a command line or shell script that's easy to edit because it's basically one command line.

got it.. thanks.

finally, thanks guys.. every single issue i had has been resolved including the usb bandwidth thing even tho one of them is still playing catch up... seems the issue was related to windows...
Im currently running rasp OS on one of my pcs and so far so good...

just waiting for the usb amp meter i ordered on amazon to set all the sticks at a set power rating...

Hi all,
with the difficulty to buy a good usb mining hub , I finally worked on my own design
https://i.ibb.co/Nj56pdq/usb-mining-hub.png
main features :
pci-e power connector 12V
3 power linear regulator 5A each
3 variable resistor to adjust 5V output
Atmega328 with LCD to display data like power of each usb port like usb key power meter

4 ports USB and 2 with just power for raspberry or fan

ports 1 and 2 share same 5V with usb hub data
port 3 share same 5V with one usb hub data and port4 with just power (fan, raspberry)
same configuration for port 5 and 6

I plan to add connector for fan because a thermal dissipator is need for the 3 linear regulator and a sensor to manage temperature

It works since one week without any issue
https://i.ibb.co/Kz3t75m/cgminer.png
Now I need program ATMega to display data and my prototype will be finish

Looks great, I am sure there would be many of us looking to purchase something like this.  I am also waiting to get a GekkoScience hub and check everyday to see if I can purchase one.
