Update on my R606. It ran 24 hours on 650m V6 so tried bumping it up to 700. Immediately threw a wobbly so turned it back down. It seems its no longer happy at anything above 650m.

What would be the reason for it suddenly not being happy where it was? degradation in the chips perhaps?

It wasnt really hot like you would burn yourself. But hotter than i expected. It never had the flashing lights related to temp either. Ran for over a month with no issues at all.

Fully appreciate this is out of its standard range of operation and fully expect something to happen but I’m curious what the cause could be. No other reason than my own lockdown boredom curiosity lol

Edit. Boredom got the better of me to taking it apart to look for any damage they may have been caused when it was running hotter than expected. Nothing of note although mine has got some writing on it saying “12 Slow”. Have I stumbled across a secret binning note? 

If there's a number on the heatsink it's the bench serial number used to identify them during assembly and testing. Once they're done testing the final step is re-flashing with the unique serial number and another quick test before packaging.

If something fails test I'll make a note of the problem so I can fix it. The "12 slow" means the last chip in the string was dropping speed during burn-in, so I took it apart and replaced that chip then ran it again.

Hello. It is close to impossible to get multiple Gekko Science miners to work at 500Mhz! Got orangepi, gekko usb brick and 3 stick by now, to get each to work at 500MHz takes quite a lot of time, but when I plug them in all. No chance! Resetting, down clocking, crashing. Even tho I didn't expect any return from any of this mining, I really though  I can just get couple of those to run stable..but no not really.

Quite disappointed after days of voltage tweeking and moving stick by stick all around the hub...
Feels like cardinal waste of money trying to have small usb mining farm...Yes ofc I know 500Mhz is high..

Orange Pi 3, Armbian Bionic 20.02.1, Sipolar USB 10 ports 60w, Arctic Cooler active fan.
I seem to be unable to even get second stick to run at 500Mhz. Always downlocks to 470-85Mhz, if I connect three one is dropping with 0 chips found. The other two seem now stable at 450Mhz.

Hi, I've encountered some issue running gekko on my orangepi.

I'm using ssh to access my orangepi and using screen/tmux to keep cgminer running after i log out the ssh session. Weird thing is, if I keep the ssh session running the cgminer works fine, but if i log out for a while, the cgminer will stop in mins and show "usb transfer err:(-9) LIBUSB_ERROR_PIPE 3476 Segmentation fault", and mining stops.

Could anyone help?

Yes, I use a Pi4 for my two R606's.  No hub needed for me.

I wasted allot of time dinking around with a couple Win7 machines.  It was slightly fun and educational.  But I love my Pi4.

Do you reckon that 60W Sipolar brick should manage 4 NewPacs, or is it not enough?

Update: after recompiling MXE I am now getting a different error

You need to read the CGminer readme files and check the CGMiner thread.

I know very little about compiling the source.  But there is no "--enable-blockerupter" option as it uses the icarus driver, there is no need to disable gpu support as that was removed in 4.8, I beleive, and I have never seen an "disable" switch so I don't think there is any need for that.
