GekkoScience has a new stickminer that does 300+GH

[kano]

cgminer must determine if a share (nonce) should be sent to the pool.

It would be really bad if it couldn't do that

When you tell cgminer you want all the extra information it can throw at you, by telling it '--verbose', one of the output lines is to tell you what it does with each nonce the chip returns to cgminer.

At 260GH/s you generate around 60.5 nonces of 1 difficulty, per second.
My pool doesn't want you sending that much crap to it
Nor do you want to increase your network flow by 202 times

My pool will set a work difficulty so that you are sending shares at around 18 per minute.
Thus cgminer must work out what difficulty each nonce is and if it should send it.
In verbose more it tells you for, on average, 201 of those 202 that their difficulty is too low.

Code:

 [2021-10-29 09:28:27.862] Accepted 4b97ce57 Diff 867/788 GSF 0

This means the pool is asking me for shares of 788 diff or higher (one GSF + one GSI)

Another way to look at this is that it means, on average, one in 788 nonces returned at 1 difficulty will be 788 difficulty.

However the driver I wrote will have already set the chip ticket mask (difficulty) to 16 at this stage, so only 16th of the nonces are returned by the chip over USB to cgminer.
Thus you'd see 16th of the messages in verbose mode.

@kano All I can say is thank you. All the struggling to learn about mining over the last months just paid off in your one message. You really did simplify the complex, at least enough for me to understand it!

Thats probably why it hasnt been mentioned. Its not as linear as the previous sticks. Cheers Kano.

EDIT:-

Just throwing this out there. But would there be a market for a dual to single usb pcb to join two ports together on the gekko hub? So you can run a compac-f at full speed?

Er? Why? to feed the F 6A?
You can already do that with his hub -- if you do not mind vastly overloading the USB socket, just leave the other port open, plug in the F and crank her up. A dual to single adapter still faces that max 3A limit for the single socket.

I just installed meters between my sticks and the hub. I'm getting just under 5V at just under 2A per port. Is that sufficient to run at 400?

[NotFuzzyWarm]

Only 1 way to find out -- try it.
Again, the USB meters only show what is feeding the stick and how much current it is pulling. No matter what the voltage should always be close to 5vdc and under heavy load at most drop to maybe 4.5V. Current will all depend on what speed you are running at. If you tweak Vcore a little higher using the very tiny pot, expect the current to go up.

  Bitshopper deliverd the Gekko-F.
I tryed it on 200 MHz at first, but this thing liked more 350 MHz to run smoth.
Now it is set at 400 MHz 475MHz to Kano-Solo-Pool (yes Kano, I read the README)
I will let it run there and hope some lucky miner hit a block.

NB: I tested the gekko-F together with a gekko 2-Pac, an U2 and a Block Erruptor (333MH/s) as well a R-Box.
cgminer got no problems in the mix, detection was without a fault, and all run together as a team.

[Sledge0001]

Well after a week or so of tweaking here is what I have learned personally.

These Sipolar USB hubs https://www.amazon.com/gp/product/B01K4MZQJ8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 do not want to see these sticks run at anymore than 2.84 - 2.87 amps at full load. If they trickle into the 2.9A+ range the ports shut down.

Only 2 sticks per 10 Port Hub seems to work the best with a single Arctic USB fan running on each. https://www.amazon.com/gp/product/B003XN24GY/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

My older icone hubs seem to like 2.95Amps per stick but still with a limit of 2 sticks and an Arctic USB fan per 10 Port Hub.

This gets me averaging about 315-330GHS per stick over a 24hour period of time running at 500MHz.  

I am running all of 11 of these + 6 of my 2Pacs on Kano's Solo Pool for those members please see me on the pool stats!

So just use sidehacks hubs... Port power is set up with each set of 2 ports fed from 6A which allow a full 3a per set of ports or if you do not mind the chance of frying a connector, 6a from 1 port in each set. FYI, USB-A connectors are rated for 3.1A max

All depends where you are in the world. Bitshopper.de has stock of them at the moment. They are based in Germany.

I'm in Chile so I am guessing that ordering from the US would probably be the easiest.
I haven't had much luck finding anywhere at the moment that has stock.

Hello, i have a problem i hope you can help with. I got my compac f today from bitshopper and i want to use it to solo mine Cheetahcoin (CHTA) with it. I've already been solo mining CHTA with 4 newpacs for a couple of months without any problems. I've downloaded the updated cg miner and installed the driver using zadig. I compiled the bat file with the same credentials as i used for the newpacs, but now i'm getting the following error:

 [2021-11-02 16:43:57.066] No Stratum, GBT or Solo support in pool 0 http://1xx.0.0.1:8xxx unable to use 

   My batfile looks like this:

cgminer.exe -o http://1xx.0.0.1:8xxx  -u bxx  -p password --gekko-compacf-freq 200 --btc-address xxxxxxxxxxxxxxx           

In cg miner 4.11.1 it's working fine for the newpacs, but in the 4.12 version i don't get it running. Anybody got any idea what i'm doing wrong? Thanks in advance!

[gt_addict]

Just want to say these Ferrari's are AWESOME. 6 of them running 500m getting 1.8Th and using just 93w      Great for us Home miners. Thanks sidehack and team.

have you tried running the newpacs on the new cgminer?

Yes and those aren't working either in solo mode. I pointed de compacf at a pool for now, it's solo mining there, and working fine now. Great to see the hashing power!

Curious how most of you run these sticks.  I have a friend who has access to a large qty of surplus (free/used) 350W wind turbines, 200W PV panels, and large 4D AGM deep cycle batteries. 
I suggested building a couple of totally renewable off grid compute setups.  We would probably just use our local internet/wireless networks to avoid paying a 4G modem charge.

Ideally I can build it in a way that I run them as miners working for a local full node on an RPI, but for the short term it seems easier to just solo mine to a pool.  I've never personally operated a node. 

I doubt its worth trying to mine them for dust, Id imagine these are basically all considered solo mining lottery tickets?  Really curious what you all think.  Excited to build something like this.

[NotFuzzyWarm]

It is best to ALWAYS use a known solo pool for mining with any stick miner vs mining to your own node.

Reason is simple: Connection times to the worldwide BTC network.
Any block you find must be distributed to all other mining nodes as fast as possible to ensure your block is the one that gets confirmed. Considering how very very very very very unlikely it is that you will find a block, it would truly suck to get one and then have an orphan race with you losing because a pool with faster connectivity beat you to it. Any decent pool uses dedicated connections and routing to the BTC network vs your normal home internet connection which will take whatever path is available at the time.

At current BTC value of just over $61k USD I for one would never risk losing $381,250 as loser of an orphan race...

I completely agree with !Fuzzy.  However you can still put your full node at the end of your failover list.

[sidehack]

If you do build something out with renewables, I'd be interested in seeing pics of the setup. Always interested in green energy here at the Gekko.

However, this does lead to the misunderstanding that mining to a full node without internet access is a good idea

If you are having random internet access loss to a pool, either you're mining on a dodgy pool and should pick a better one, or your internet access problems will most likely also affect your node so that it doesn't see block changes until the internet reconnects also, so you could be mining on stale blocks that will never get a reward (like that other dodgy solo pool has done before ...)
