GekkoScience has a new stickminer that does 300+GH

[kano]

how does the whole thing behave if i use e.g. 2 gekko usb hubs with 3 compac f each?
does each hub then have its own mining power from the 3 miners in mentioned or can the mining power of the two hubs, which is generated by the 6 miners, be merged?

All miners on all of the hubs are automajikly found and used by the 1 instance of cgminer. While each stick runs at its own (varying) diff and reports its own results, the total hash rate of all the miners are combined and reported as an aggregate hash rate.

cgminer has various options explained in the README to do various setups.

However, all miners connected to a single cgminer instance are treated as a single larger hash rate at the pool (as Fuzzy said)

If you wish individual miners/compacf's to use individual workers and pools, you must run a separate cgminer for each one.
Yes selecting which USB miners each cgminer will use, has been part of the code for a very, very long time
Also as mentioned before, the additions VH did were all added also.

Well, I finally get my Solo Mining setup working. I put a 120mm fan in front of the Compact F and now its very cool (about 42°C). Didn't thought that would affect cooling that much. Without cooling at 200Mhz it's to hot to even touch the heatsink. Now it's running at 400Mhz. Maybe I go a little bit higher the next days.

But now I've found another problem with my setup. the latency to kanopool is quite high. As I'm from Germany, I use the server in the Netherlands. So I started some ping tests:

Code:

maik@ubuntuserver:~$ ./stratum-ping us-east.stratum.slushpool.com:3333
...
avg 109.028696ms

maik@ubuntuserver:~$ ./stratum-ping sha256.eu.nicehash.com:3334
...
avg 25.584321ms

maik@ubuntuserver:~$ ./stratum-ping stratum.antpool.com:3333
...
avg 20.263655ms

maik@ubuntuserver:~$ ./stratum-ping solo.ckpool.org:3333
...
avg 97.443751ms

maik@ubuntuserver:~$ ./stratum-ping nl.kano.is:3333
...
avg 246.267585ms

Maybe it would be better to mine with my own bitcoin node? But my node is bitcoin core 22.0 wich doesn't work with cgminer  
Which bitcoin node version uses kanopool?

Um, you must be doing something terribly wrong with your internet or there's something wrong with the program you are using to test.
If you are using a VPN or Tor or other similar delay on your data, then that's a really bad idea and the cause of your terrible latency,
and on top of that, your ping values are meaningless since they will change regularly when using such connections.
If this is the case, then yes please don't mine on KanoPool with those added delays.

From the German (frankfurt) node to the Netherlands (amsterdam) node in only a 7ms ping.
Again, if you are getting a 246ms average ping, then you are doing something terribly wrong with your internet.

I tested again with normal ping in cmdline and it shows avg. 12ms to kano.is. with the stratum ping tool it shows 140ms. so there is something wrong with this tool obviously.
I have a FTTH connection and using it without a VPN or Tor so this should be good. cgminer is running in a ubuntu VM on my home server.

I used this tool: https://github.com/2miners/stratum-ping/
Don't know why this shows such values.

The program's output is useless since it is giving you information unrelated to the mining performance.
It uses the time to connect to the pool to decide how the pool performs, which is completely incorrect.

Okay that's interesting!
Thanks for the clarification.

Can you help me?

Ports 2 and 5 on my Gekko usb hub stopped working, I tested it with a usb meter and it doesn't show it has power.

Before they worked normally, unfortunately the compacF was like ZOMBIE in cgminer and I noticed that.

Is there anything I can do or are the ports already gone in this case?

[sidehack]

Probably the voltage regulator chip roasted. Who'd you buy it from?

Thanks sidehack, for the answer.

I bought from 419mining.com, I've already sent 2 emails and they don't respond, the hub hasn't had 2 weeks of use.

I have another usb hub gekko that when I put 4 compacF ports 2 and 5 are being disabled by cgminer, I'm using 450mhz in the configuration with ventilation, I tested with 300mhz and I had the same situation.

If I only leave port 2 with compacF, it works normally, would this hub be causing problems too? In this case it worked with 4 compacF (ports 4 and 7 are ok) for 1 week.

I have a third usb hub gekko with 4 compacF (ports 2, 4, 5 and 7 with compacF) and it works normally for 1 month.

Can you help me by asking 419mining.com to respond to support emails, please?

Thanks.

[sidehack]

I can, yes. In related news, we're working on a new hub design with better failure protection and power handling.

The ports being disabled by cgminer, more likely what's happening is the regulator's running weak or hot and when two sticks are plugged in, it's turning off.

The lines between ports on the top case indicate which ports share a voltage regulator. It's also noted on the label on the bottom. If you're having trouble, try 3 sticks per hub, one per linked pair. Might also help to provide a bit of airflow into the hub itself.

How long you pretendes sell the new usb hub? Do you have idea?

Can a technical person in electronics change this regulator chip or is it not possible to change it?

Really, when I use 3 compacF on this usb hub gekko the usb port stops being disabled by cgminer.

I already have ventilation in the hub too, the environment of the hubs does not have a high temperature, even putting your hand close.
What I notice is that I'm losing usb ports little by little.

[sidehack]

If you've got a half-decent hot air soldering station, or an iron and some skills, replacing a regulator chip is pretty easy.

Sidehack I'm already in contact with 419mining, thank you very much, I believe I said something.

I still have a gekko usb hub with a problem on ports 2 and 5 when I use 2 compacF, I have a gekko hub that works normally with 4 compacF, but another cgminer keeps disabling these ports if I try to use 2 compacF together ports 2 and 5.
I've already put ventilation on the hub, it decreases to 400mhz (normally I use 450mhz) and even then only this hub has this problem.
Is there something to do or is it a problem with the voltage controller as well?

Thanks.

Have you tried using one of the USB power meters that we post in this thread?  They just go in between the port and the CompacF to tell you how many AMPs it is using.  I ask because you could have two sticks that even though they are low on the frequency the actual voltage regulator on the CompacF (the little adjuster on the bottom right of the CompacF) may need to be adjusted.  If both sticks are seeing 3A or more it will cause the hub to shut them down as well.  The combined rating for each pair is 6A.  I only suggest this because I have had this happen in the past as well.

[cygan]

i think i saw somewhere (now i don't know if here in the forum or somewhere on twitter) that there is also a power consumption indicator/display for the own small gekko mining farms, which is connected via usb to the respective hubs. or am i wrong here?

That would have to be a stand-alone device. AFAIK the hubs do not have any voltage/current monitor circuits that can provide the signals need to report power used and report it via USB.

[sidehack]

That was an idea we had at the beginning but which wasn't implemented.

[cygan]

thanks for the info guys.
i will in any case continue to keep an eye out and when i have found it, i will post it here including picture

I have the usb meter, today it is reading 2.4 to 2.7A the stick.
Could you tell me how the adjuster works (left side what does it do? right side?) so I can adjust?

What value would it be good to adjust and leave?

Thanks.

Are you referring to this?



If so that is mine lol.  All that is measuring though is total power consumption across the PCIe power.

no, i think that was this one... but this is a usb meter and completely different



what you show there, i think is what i'm looking for
but aren't the things always connected directly to the mining power supply? as seen here on the picture



and how strong of the number of watts, in your opinion, should be a mining power supply, if one would come with the a few gekko hubs including compac f and later maybe a few gekko terminus r606?
and which mining power supply would you recommend including the power consumption indicator?

[NotFuzzyWarm]

Let's see, 15 watts max per stick x 5 sticks per hub x number of hubs, add in Terminus power + 20% reserve margin...
Yep, must be rocket science
