GekkoScience has a new pod miner, just in time for Christmas

[kano]

Well, since you are solo mining, use my pool.
It also has a history graph and the best info about your mining than any other pool.
... and discord support to easily get help
I designed and wrote the cgminer API and the R909 driver, so yeah if you are mining on my pool, and I can thus see what's happening, I can help.

Though it sounds like your miner is working fine and the problem is whatever unmineable is.
I have no idea what unmineable is, but if you are having a problem with them not working, you need to ask them about it.

Hey Kano, Thanks for the tip. 

Unfortunately until I started researching this issue I THOUGHT I had been using your pool.  I made the discovery that I wasn't last night when I was web searching for your cgminer / r909 setup page and stumbled across your pool page.  I did switch over, and everything seems to be working as it should. 


As for unmineable, I did put a support ticket in with them earlier in the day, but they are slow to respond.

Thanks again.

Hey, is there a problem with R909 (cgminer) and Nicehash? Every time I mine on Nicehash with R909, the cgminer instance stops after a few hours. Sometimes it shows 0.5 ghs, sometimes 1ths, but mostly 0ths on Nicehash. Cgminer is utilizing the full Ths power, but it seems to be blocked by Nicehash. Why does cgminer stop without an error message after a few hours? Even when I do 30% solo mining on CkPool and 70% on Nicehash, cgminer stops after some time. However, if I run cgminer at 100% on CkPool, it runs for days until I stop it. Is there any way to solve this problem? My S9 miner is accepted on Nicehash.

Im using this url:

stratum+tcp://sha256asicboost.auto.nicehash.com:9200

(Same without asicboost )

[kano]

Fuckhash expect you to put a massive security breach in your miner.
The master cgminer git obviously doesn't include this hack.

The hack allows the 'pool' you are mining to, to send you work from anyone else's account, or any sha256d scamcoin, at any time.
cgminer doesn't allow this for obvious reasons.

Yeah Nicehash uses their own fork of cgminer, because of what kano explained in his previous message.

Personally, I wouldn't recommend using a cgminer other than this one (the one created and maintained by kano), and suggest you think twice before using shitty version from Nicehash.

hi everyone

I have a GekkoScience R909 problem I am having is the speed is  unstable when I use it with compact f seems to go up and down and it stays at around 68 to 70% speeds range from 1.155T 1.480TH and 1.731t up to 2.274th,  when I use the r909 on it`s own there  is no issue just does not work with compact help anyone encountered this before. running the miners on i9 pc os ubuntu


thanks to anyone who can help

I saw the same issue when trying to run 8 Compac f with two R909s.
This wasn't because of CPU overload, since CPU usage was only at 30% (12th gen core i5 with windows 10 PC).
This computer can run 50+ compac f and upto 9 R909 without a problem.

The devices run fine individually but the problem only occurs when running them together in the same cgminer window.

I tried running two seperate cgminer instances on the same computer, one each for R909 and compac f and that seems to fix the unstable hashrate issues.
I used

Code:

--gekko-r909-detect

&

Code:

--gekko-compacf-detect

to enable only one type of device in each cgminer window.
I'm not sure why this works, but I'd suggest trying this out.

Hello! I recently moved homes and today at my new place when I tried to run my R909, unfortunately, it shows 0 chips found. I guess something went wrong during shipping.

Anyway, I just dissembled everything. When it's connected to the power cable but without running the CGminer, Chip '1', '2' and '5' (which are on the same side) are hot while the other 3 chips are cold. I wonder in idle, should all chips be hot or cold? and what could possibly cause this ''half hot, half cold'' scenario? Many thanks!


Picture of the dissembled board: https://www.dropbox.com/s/ctkr7t50n6vdski/PXL_20230415_164621233.jpg?dl=0

Did you ever find a solution for this?  One of my R909 is displaying the 0 chips found this morning.  It has been running fine since I purchased it at the beginning of this year.

The miner is guaranteed to run at 1.5TH from under 100 DC watts at stock voltage and do it nearly silently. Better performance isn't guaranteed, but is probably attainable. Take for example the test unit I had running 1.8TH at 70 watts, or the above-photographed machine which pulled down almost 2.1TH from 88 watts (on stock voltage, no voltage tuning) for over a week:

I finally got around to doing some power testing on my unit and I'm really impressed. After having owned a Futurebit Apollo that operated at about 200W, I was looking forward to the R909's sub-100W rating.

But in practice, it's even lower!
I haven't fiddled a lot with voltages, and I'm getting about 1.88TH/s with <85W at the wall (including power for the Raspberry Pi)! I'm using an old Seasonic Gold rated PC power supply that's not even at peak efficiency, since it's rated for 450W.
Without cgminer running, my meter was reading about 12W, actually. So if you're running cgminer on some sort of homeserver that you have up & running 24/7 anyway, you can save another 10W.

For one R909, a ~120W PSU would probably be perfect efficiency-wise (they are made to peak at about 80% load).

This makes it really viable to even do lottery mining in central EU where we pay on average about 30 cents per kWh. Basically, this unit will cost you under 20€ in electricity per month. Or, of course, you can go with a pool as well. cgminer runs quite stable for me on a Raspberry Pi, connected to kanopool. I will write a small guide for that soon.

The EU average price in the second half of 2022 — a weighted average using the most recent (2022, semester 2) data for electricity by household consumers — was €0.2840 per KWh.

[aniplex]

how do you get the R909 to work? Ive tried on windows10 and windows 11

Device not detected at all. so its not connecting as an unreconize device it just not connecting at all. have tried multiple ports ect as well. It powers on so guessing the power is good, maybe usb cable? never heard of them being bad, dont think ive come across 1 my whole life that was bad lol.

[os2sam]

Did you install the WinUSB driver?

[aniplex]

Did you install the WinUSB driver?

are you refering to zadig to install winusb to the device? if so zadig doesnt detect the device as connected so no ive not installed it.

[os2sam]

Well, you have to get that done, it's not optional.

Yes, I'm referring to using Zadig to install the WinUSB driver.  So if the device isn't being recognized then you must have bad hardware somewhere, miner, PC, cable, Power Supply, ...

thanks, ive tried 2 different pcs so doubt thats its. it does power up fans and lights so not sure about power supply. it has 3 lights it looks like on the mb only themiddle lite comes on. looks white or pinkish. not sure if that helps. so probably a dud miner ill try another cable but never heard of these going bad unless extreme useage.

[os2sam]

Well, I guess after you try a new USB cable, you need to contact the dealer you bought it from.

Most R909 wont run at 100% if you push the clock speed.

Spamming threads to get post counts ...

Anyway, no, they will get 100% is you push the clock speed ... up to a point ...

Got my first R909 today, love it!  Nice work Sidehack!

[saeshtoshi]

Hey plebs,

I am new to this forum. Found you guys while setting up my 2x R909. I am into Bitcoin since end of 2020. Made my first newbie umbrel node in 2021. So the next step is hobby mining. Especially with the side effect of using the heat.

So now I am Solo mining with Kano's pool. First of all: thank you Kano for keeping up the good work with the cgminer. I am using cgminer around a week now and I am really happy with it. Also thanks to Sidehack for the valuable posts I have read.

Now to my R909 double team:
The controller is a RPi 4 2GB Raspiblitz Bitcoin Full Node. Through a good 3A USB 3.0 HUB the Pi-4-controller is connected to the R909s (blue USB 3.0 port at RPi). The power supplies are two brand new 150W Jack devices.

The first R909 is a mf beast. Blue voltage controller knob was set to around 11 o'clock since the beginning. The beast gave me 2.6 TH/s at 650Mhz WU:100% STABLE. So I was happy as fuck to be so lucky in the silicon lottery. Then I ordered a second one and directly ran them together... but it was pretty slow. The second R909 had the voltage knob at 1 o'clock. So I tried to play with the voltage and the frequency without having a real plan. So at first my best setting was 2x R909 at 550 Mhz making around 4.2 TH/S. The higher I went it always turned out to be the same: the second R909 lost efficiency over the course of a few hours.

Then I was fed up and wanted to analyse both of them separately. So both blue knobs to 12 o'clcok and then increased frequency by 25 Mhz, starting at 450 Mhz. giving them around 20 min. Setting display zero 1 min after target frequency was hit.

Summary:

1st R909 (blue knob 12 o'clock)
550 Mhz: 2.237 TH/s avg - WU: 100% avg
575 Mhz: 2.285 TH/s avg - WU: 98% avg
600 Mhz: 2.415 TH/s avg - WU: 100% avg
625 Mhz: 2.480 TH/s avg - WU: 98% avg
650 Mhz: 2.600 TH/s avg - WU: 100% avg (sweet spot in my opinion - takes more energy but also a better heater   )

2nd R909 (blue knob 12 o'clock)
550 Mhz: 2.107 TH/s avg - WU: 100% avg
575 Mhz: 2.250 TH/s avg - WU: 98% avg
600 Mhz: 2.350 TH/s avg - WU: 97% avg
625 Mhz: starting good at 2.400 TH/s avg - WU: 95% avg...after 15 min it started slowing down...to after 20 min: 2.335 TH/s avg WU: 90% avg
so I put the blue voltage know a little bit more clockwise to around 1 o'clock:
625 Mhz 1 o'clock: 2.450 TH/s avg WU: 97% avg (sweet spot in my opinion)
650 Mhz 1 o'clock: starting at 2.400 TH/s avg - WU: 89% avg...after 15 min it started slowing down again....
so blue knob to 2 o'clock:
650 Mhz 2 o'clock: 2.200 TH/s avg WU: 80% avg seems to be the end for the second R909

Then i ran them TOGETHER again and tried 625 Mhz at first -> which started at nearly 4.9 TH/s and it seemed to be stable for an hour... just to then slow down again...  

In the end their Team-Sweet-Spot is at 600 Mhz at around 4.5 - 4.6 TH/s average stable... until now...

Can someone give me advice how to run them more efficient as a duo? I can see some people running them with different frequencies in one cgminer. Haven't found out how to do this yet. So I could try to run them both at their individual sweet spot.

Thanks and Cheers to all you guys!


edit:
ah okay I found how I change the frequency when already running.....the JAVA API scripts

Total electrical Power used from 2x R909, RPi 4, USB-HUB = 275 Watt  

hope this plays out to be stable  

any suggestions how to tune the second device... I am not sure where the WU should be "at least"..:?  

edit2:

Finally found the ultimate sweet spot which is super stable. Both R909 at 650 Mhz. First one > blue voltage knob at 12 o'clock. Second one > at 1 o'clock.

And the thing which makes the difference: An extra FAN before the 2 R909 Fans. Means my problem was a problem of the temperature, which let the second R909 lose it's power every time after about 3 to 4 hours mining. Now I ordered 2 Noctua NF-8 Fans with 2200 RPM.

Stable at 275 Watt (including RPi and USB Hub)
