Re: GekkoScience has a new stickminer that does 300+GH

In June I purchased the bitcoin merchant 3x Gekko Compac F combo with Raspberry Pi 4 preinstalled with cgminer.  I set and ran them at 400 MHz for two months before one mining stick failed.  I have since rotated their positions in the USB hub and the stick is still failed with blue on, red on, white off lites.  Is there additional troubleshooting?  Is there any warranty? Can the stick be repaired or should I just replace?  I am at 37,690 satoshi on Slushpool and can continue with the two stick miners.  I am a novice at desktop BTC mining.

So I got the three Ferrari's without the "kano" gekko support on a flashed sd card that came from the BitcoinMerchant kit.  They are running just fine at -freq 400 as advertised.  I don't yet have the skills or experience to flash my own cards so my best option is to purchase a new sd card with the kano support. (preferred)  Where can I buy this?

When entering the below command the response is --gekko-mine2  unrecognized command

cgminer -O stratum+tcp://us-east.stratum.slushpool.com:3333 -u xxxxx -p xxxxx x --suggest-diff 512 --gekko-compacf-detect --gekko-compacf-freq 500 --gekko-start-freq 400 --gekko-mine2 --gekko-tune2 60

I am running cgminer version 4.12.0

Please advise what is wrong and how to correct this.

Seems like you didn't build it with gekko support.

As seen in the README and kano's instructions here, you need to build cgminer with --enable-gekko, something like this for example(not sure why kano uses --enable-icarus, it doesn't seem to be needed):

CFLAGS="-O2 -march=native -fcommon" ./autogen.sh --enable-gekko

I just recently purchased "3 x GekkoScience COMPAC F with Fan Upgrade + Bitcoin Merch® 7-Port USB Hub - COMBO Up to 1.05+TH/s" from Bitcoin Merch and I am not getting the 1.05+TH/s stated.  Instead I am getting at total of 291.4g from all 3 miners (each miner @ around 93.59g).  Can anyone tell me why this is?  Is it because of the 7-port USB Hub not providing the required power?  Here are the commands I am using to start cgminer:  

cgminer -O stratum+tcp://us-east.stratum.slushpool.com:3333 -u xxxxx -p xxxxx x --suggest-diff 442 --gekko-serial "GS-100xxxxx,GS-100xxxxx,GS-100xxxxx" --gekko-compacf-detect --gekko-compacf-freq 400 --gekko-start-freq 400 --gekko-mine2 --gekko-tune2 60

Thanks.


I have the same setup from the same supplier purchased with the Raspberry Pi 4b 2GB running all 3 sticks running at 400hz.  Slushpool reported a maximum 5min rate of 1.047 TH/s and a 24hr rate of 775 GH/s.  What computer are you using??

cgminer command line for 3 Workers

To start my bitcoin mining experience I have purchased the bitcoin merchant 3x Gekko Compac F combo with Raspberry Pi 4 preinstalled with cgminer.  I want to set each mining stick as a different worker on slushpool.  I enter the following terminal commands:

cd git/vthoang/cgminer
sudo  ./cgminer -o stratum+tcp://us-east.stratum.slushpool.com:3333 u myacctname.palermo1

Terminal responds showing 3 chips ramping up to 200-300 h/s each

Switching to slushpool shows one Worker named palermo1, status OK ramping up to 302.8 GH/s scoring hashrate.

This appears to be only one chip working???  All three sticks are blinking and working minimal heat.  How do I change my code to get three workers running around 300 GH/s each?

Help appreciated as I am having difficulty learning to do this.
