If it behaves the same even with an R606 plugged in, it's not a USB throughput limitation because bandwidth use is directly proportional to total hashrate. Does it matter how ports are used on the hub?

Ok, next question  ok USB stats on this board:


Below, Only referenced the usb headers only

Not overly familiar with that board but I am curious if the ports on the back are sharing lanes.  As from looking at photos of this board, you have 2 x 2.0 usb slots just above a mouse ps/2 port.  And 4 x 3.0 at the ethernet port.   I'd suggest mixing these ports up a bit as a test.  Plug the R606 in the top 3.0 port just below your ethernet port.  And then try the top 2.0 port for the newpacs.  If the NP continues to not work properly.  Then try the next 2.0 slot below it.  Test every port in this manner while the R606 remains in the one top port.

If all that continues to create the same issues.  Your next method would be to use the front ports.  Since this is not in a case you will need to find a way to plug a usb header cable into one of the usb header ports on the MB.  As you currently have 2 for usb 2.0 and 2 for usb 3.0.   Those hopefully will run on different lanes.  


Last option, pick up a raspberry pi 4, throw them into a closet and call it a day  


But that's the only thing I can think of testing on your setup.  I wouldn't think the motherboard should cause an issue but never can tell.  That's the only thing I can think of left to test.   Each lane and then get one pluged up using the header ports.


And the Intel I3 or power supply would not be an issue.  I had 2 x R606, 4 x Newpacs and 2 x Moonlander 2's running on a Fx8350 on a MSI FX970 gaming motherboard (old hardware since I upgraded my main rig to a Ryzen system).  They worked perfectly.  I've then since moved them to a Raspberry Pi 4 since with the cpu basically at idle the Pi pulls in less than 2 watts compared to a hungry FX8350.

hey guys, thank you for taking the time, I am running ubuntu 18.04 on a gygabite Z170-HD3 DDR3, cpu is a intel core i3-6100 3,7GHz, OS is on a ssd

psu is a corsair CS550M, nothing connected to the mobo, it's a remote machine, just the ethernet cable, the r606 and the gekko hub

only thing I had to leave connected is the hdmi cable plugged into the mobo and the screen (monitor has no power whatsoever) because for some reason without I couldn't share its screen (all black)

for the gekko I tried different usb ports, 2.0 and 3.0, shared and not, even without the terminus, same thing, the r606 seem to not mind which port is running onto

I tried the newpacs one by one and singularly they all run great, also in pairs, trouble starts when I run a new instance for one of the other two (one or both)

I also tried to connect them all to the gekko hub and run them one at the time using their serial numbers (--gekko-serial), they all are fine until I start the third and/or forth, doesn't matter which one

anyway I can test the bus / traffic lanes of the motherboard not being able to keep up as you suggested ?

here is the pc:

Looked back through the postings.  Margotcoins was using Ubuntu 19.10 and Sam recommended backing down to the prior 18.04 LTS release.

What motherboard are you using?  I'm wondering if there is a usb traffic lane issue similar to the Raspberry Pi 3's.   As not all MB are created equal.  Since you are fine with the R606 and 2 NP just not with 3 or more.   If you swap out two NP for the other two and still run just fine then we know there isn't anything wrong with the NP or R606.  It could possible be narrowed down to the bus / traffic lanes of the motherboard not being able to keep up.

I believe they're running linux, but will need them to confirm.

margotcoins....what OS are you using? Just re-read the last couple of thread pages and couldn't see if you mentioned it.

absolutely same result with the brick

all 4 together they just won't run stable (or 3)

but with 2 or less at the same time I am great

EDIT: no sure if it might help to diagnose, I tried running all 4 stick at freq 75

so by the formula 75 x 0.228 = 17.1 Gh/s

same behaviour, the first two sticks I start run perfectly at 17 or even a little more

as soon as I start the third and/or forth boom, they all start jumping up and down, even dropping to 1 Gh/s and then trying to go back up, with WU % around 50 % or less

You said the r606 brick had no change on the np's functioning in our exchanges?

so (I think) I made some huge progress and thought I share the results:

the terminus has been running rock solid and cool at around 1Th/s (thanks to minefarmbuy help)

the sweet spot for me was setting 5 on the vcore or 440mV and 900 freq (edit: I am also experimenting with 875 and 850 seeing that the r606 always seems to stabilize at 825 by itself)

(edit2: I am getting almost the same hashrate with freq 750 and volt 6 so I am running it this way, way cooler and less power)

temps look great, the heatsinks sit at 29C (above) and 33C (below), air coming out almost feel "cold" ! room temp is around 24C


the newpacs (I have four), well, these little fuckers are putting up a fight, but also I think I might be on the way to figure it out (hopefully with your help)

what did it for me was isolating (got it from the thread not my idea) and running separate instances on cgminer

problem is if I run one or two sticks they run great (98-99 WU)

when I start the third instance is where they all start to jump all over the place and usually getting 40 to 50 % WU with spikes to 80 % ( at 200-225-250 and even at 100 freq)

can anyone point me to why that is ? I though it might be a power related problem but even when I just run the gekko 7 port hub without the terminus I get the same results, I don't get it !

any help very much appreciated !

setup is a psu corsair CS550M powering only a mb and cpu running ubuntu 18.04, no video card

what do you guys think ? it's really driving me crazy

EDIT: I get better rate with 2 sticks instead of 4 so I ended up unplugging 2 ! still I would like to run all four ..

thanks - will do this next time I am at home.

I read the posts before, i know you say hw dont matter as long as the hash rate is fine. but within 10 minutes i have almost 50 hw. any advice what to do. I am running them at 200 mhz with a fan, did not adjust anything else.

Sorry about that guys, we posted 2 holdovers we had for RMA replacements but they sold within minutes. We have not received the large stock update from GekkoScience yet.

I've tried to get either the R606 or my newpacs to run on nicehash but never had any luck.  With either of their SHA256 or ASICBOOST SHA256 addresses so gave up on them.  I would get an accepted share and then go half hour or more before it'll ever get another.    Since Prohashing has added bitcoin as a form of payout I've got all of my miners pointed there.  Between the two R606's, 4 newpacs, a GTX 1070 and GTX 1050ti  (figured why not since I have these cards just lying around) I pull in about a $1.25 worth in bitcoin a day at our current market price on average.

As for creating a log, try this:


This will create a log file called out followed by the date you start it up .log

not sure how to do that. my ability with using cgminer is very basic

Pipe the output to a log file so you can see what errors are popping up that would cause a re-target.

I will try a usb 2.0 - I cannot switch to linux unfortunately - not without buying a second pc - there are too many things I run on this one that do not work in linux.


I have tried a few pools - I tried Nicehash because when it does mine there, it is actually quite profitable - almost 50 cents a day lol I have mined on poolin it makes about 16 cents a day there Mostly I solo mine with it on ck solo pool.

it does try to run at 630 (I have the freq set to that) and on setting 6 for the voltage it will do it for a few hours but after a day or so its back down to 550

this is my current line for ck's solo pool:

Not sure what pool you're using but if it's not ASICBoost-enabled your speed will be limited to ~575MHz max due to USB traffic.

Is it trying to run faster than 550 and then throttling down? Or does it initially target to 550 no matter what you put in the command line? Because that could be an issue with a config file overriding command line specs.

well ./cgminer means start cgminer in current directory.

../cgminer means one directory up.

/cgminer means start cgminer in available path variable, but this linux is an clean install.
I don't know where version 4.9.2 comes from then.


Did you try an usb 2.0 port? on my pc's its more stable than usb 3.x ports
BTW i switched to linux from win10, man this is stable. Can advise any1 to do the same.

yes it is running in windows - really cannot justify a whole new pc or even a pi just for running this one miner. and the usb is directly to a usb 3.0 on my pc.

I am on voltage level 7 or 460mV and running at 750Gh/s

well I have the hub with the 4 newpacs that connects to the motherboard, and then r606 that also connect to the motherboard ..

are you suggesting I connect the r606 to the gekkoscience 7 port base hub with the newpacs ?


got it, I thought failover was more for ports and not for the entire pool

if you run solo on ck what failover pool would you use ? thank you !
