Thx. I'll try that.
I put several stuff in my /etc/rc.local for startup. The cgminer-part:
screen -m -d -S ckpool /home/username/cgminer-gekko-rev2/cgminer -o stratum+tcp://solo.ckpool.org:3333 -u bitcoinaddr.workername -p x --compac-freq 200 2> /home/username/cgminer_log/`date +%Y_%m_%d`.log

Hotplug the troublesome ones a few times. One of my stickers used to take quite a few plug and unplugs. Also try restarting the raspi if it fails to recognise it completely. Turn the freq down to 200m and start them up, leave them running then restart the raspi at a higher freq. I just leave mine running at 200m for the sake of 1Gh difference it's not worth having them stopping all the time and having to restart.
Have you got an auto run setup on the raspi?

Yes. I've turned it up to 0.77V.
October 21, 2016, 03:47:08 PM
Have you turned the voltage up a bit from stock? What's it currently set at?

Hy everyone. It's me again 
After all I've bought a new setup (after I red some advices which were given me here in this thread):
- 1x Raspberry Pi 3
- 2x D-Link 2.0 7 active USB-ports (5 USB ports, 2 charging)
- 4x Y-cables
I've choosen the raspbian image and compiled the cgminer version from gekkoscience.com.
I want to set my 4 gekkos (EU-Version) with 250MHz but 225MHz seems to be "the magic border".
Only 1 or 2 of the 4 miners do run. The rest is marked as "ZOMBIE". If I try to hotplug (warm the miner a little up
with my hands) and put it back in the Y-cable slot it says: Gekko detect (1:11) failed to initialise (incorrect device?)
Is anyone able to help?

"nice" premium, maybe wait a couple of mo for a new version (likely to be 3-5 times faster).

I just recently have seen a few COMPACS begin to surface on the net here and there. If anyone has 2-3 new units for sale, please contact me for an immediate sale! Thanks.

It's shows 6 in stock when I go to that URL

I can't say for sure what the issue is (300MHz should show you 16.5GH per stick) but I bet the issue is something to do with Windows 10, which sucks and I will never apologize for saying that.
I had to format my laptop and re-install Ubuntu 16.04 and my voltages now are 0.796, 0.799 and 0.805.

Btw, I'm using this cgminer-gekko, instead of the one posted in this thread.

Ok, can please someone confirm that with a Raspberry Pi can I get better hash rates? I don't want to make an investment and getting bad revenue.
At this point it is a learning tool.
One stick at your params (16gh, 6-8w) will produce 29 cents of bitcon/mo and use 18c of electricity if you have 5c/kwh.
With 8c electricity, you break even. My calcs are approximate.
However, it is a GREAT tool to learn mining programs, pi, how mining work, etc.
Education.
thanks, I will use one Raspberry just to keep my initial rig running up, but I'm planning to buy some cheap antminers S5.

My voltages are 0.776, 0.780 and 0.779, but I keeping getting bad hash rates using the cgminer-gekko-win32 in Windows 10 x64.
Doesn't look like you ran that very long before waiting for a screenshot.
I get the expected hashtags at a given frequency on a raspberry pi 3.

will try thanks for reply if that dont work i will have to see a time for me to meet up with you to see if you can fix these

The reset is unlikely to do anything, but if you want to try briefly shorting it to ground that resets the chip.
October 07, 2016, 03:54:22 PM
hey side hack if i have 2 sticks not working is the reset able to do somethin on them or do i need to bring them both to you? one just stoped mining and the other one is the one i got from philipma
