GekkoScience has a new stickminer that does 300+GH

[SovereignOne]

Any suggestions for correcting a lazy stick?

I'm running two Gekko hubs, three sticks per hub, powered by a 1200W HP power supply with six pin connections, so power shouldn't be an issue. Cooling provided by two 120mm fans on each, one blowing horizontally onto the sinks, one blowing down from above onto the sinks.

All my stick are running steady at 510mHz - 520mHz, but I've got one stick that chronically lags behind. I've tried bumping up the vcore to as much as 1.58v, but I've not been able to normalize it to the others. All the other sticks are sitting around 1.5v on the vcore.

Any suggestions?

I'm having trouble figuring out why my three sticks won't initialize and I've posted a few screenshots if someone could help.

My boot script has always worked before:

sudo ./cgminer -o stratum+tcp://solo.ckpool.org:3333 -u xxx -p x --suggest-diff 442 --gekko-compacf-freq 425 --gekko-mine2 --gekko-tune2 85 --gekko-start-freq 350

Thank you

What kind of USB hub are you running them from, does it have capacity to run 3 devices at the same time typically you need a USB hub that'll do 2.5-3Amps per port for the CompacF to run reliably.

I'm using the Gekkoscience 8 Port USB Hub 2.0, which successfully runs 3 sticks in the past.

I can't tell from the cgminer logging if the problem is with the sticks, usb hub, or configuration. This can be seen in my screenshots.

Try a different hub with just one stick at a time. I suspect your hub may be faulty.

I'm trying to get a build of cgminer going on my pi 4 and it's complaining about __fortify_clang_overload_arg.  Is there a specific version of the pi os I should be using?

[kano]

I'd suggest using ubuntu as per https://kano.is/gekko.php

No idea if there are problems with clang, I only build it with gcc, and also Pi5 OS has a buggy gcc in it.
They really don't support their OS with updates, use a better version of linux that gets updates.

Does anyone have a picture of the PCB board on the GekkoScience Hyena Base Hub?  I had a power outage and now I can not get the sticks to be found.  I took the cover plate off and it seems I am missing a piece on the board, it could be coincidence, but want to make sure.  

This is the part I am curious about.

Thanks for the help.

That is the way it should be. This part is not missing. It was not populated from the beginning.
