Also note that on linux the CPU% has a max based on the number of threads/cores
Didn't know Linux worked that way. My original post was updated.


Many thanks to your guide and your effort to post the information !!! THANKS !!!
You're welcome. I hope it can help a lot of other people also. It can be applied for those that use Compac F, replace "--gekko-r909-freq 525" by "--gekko-compacf-freq 525".
Also, I use "525" frequency in my setup, but I recommend starting with 400, and gradually going up. To see if there's a point where it overheats (I have an infrared thermometer) and/or gets a lot of hardware errors.


How much of a clockwise turn did you do? 1/8, 1/4, 1/2?
Also you mentioned you are not using the compac Fs.   Are planning on using them eventually or selling them?    You could get another 1.8TH with those.
I barely turned it. It must have been 1/8. I took pictures before turning it. I'll post "before" and "after" pictures, but I don't have access to it now, to take an "after" picture.
I'll be using the Compac F's Grin
Edit: Here are the before and after pictures https://imgur.com/a/F1V84qf

Got my R909 unit yesterday.

Great.  It really was "just in time for Christmas"!

Merry Christmas all.

i finally connected my 2 r909 pod miners to my existing setup today Smiley
on the picture you can see the two new r909 and on top of it a gekoo usb hub with another 3 compacf sticks. i have 3 more compacf miners, but since my rpi4 has no usb-port left, they can't be used now and in addition one of the usb hubs almost died (one usb pair still works)... Tongue
the whole fun consumes now ~250watt and the r909 fans are very quiet in my opinion ... but as AFox has already done, i will also replace it with the noctua nf-a8 pwm



and this is how the whole thing looks like at the moment:

You won't regret the fan change. Even less noise, and less vibration as the Noctua fans have anti-vibration pads on each corner.

To get more performance, you could turn the voltage knob clockwise, giving it more voltage. The hashrate should increase.
Here's pictures of the knob on mine (before/stock, and after) : https://imgur.com/a/F1V84qf

Is it possible to disable the magenta LEDs (resp. the LEDs in general) via jumper or DIP switch on the R909? Or via driver/software?

Just get a Sharpie or similar and put a little dab in the leds. It will "dim" them slightly. Personally I love the blinky lights  Grin

As reported in my pool discord #gekko channel, I've run 2xR909 and 2xCompacF on a single RPi4 and it uses about 50% of the 400% of CPU.

thank you for the note...
i was actually planning to run 2x r909 and 2x hubs on my rpi4 with 6 compacf sticks in total...
could this work well, what do you think? Roll Eyes
Let me know how it goes Smiley

on my rpi4 are now 2 r909 and 2 gekko hubs with a total of 4 compacf sticks connected
the performance is also impressive Smiley

Got my R909 delivered today and got all my miners going except the R808 I got off of ebay appears to have pooped out. It was working then got stuck on Found 0 Chips.. But that is not the point of this post.
I have to keep an eye on the Compac-F (item 5) as it appears to be sluggish. I was reporting 35%  until I captured this output. Right when I chose copy it jumped to 100% but as you can see the hash is way lower than the other compac-f (3, 4 and 6).  With this setup though I have seen the overall 5s hash shoot as high as 3.799T.

Now to start saving $$ for another R909.

If it's running slow, best bet is probably pull it, adjust the voltage up a little, and plug it back in.

How do you adjust the voltage on a compac-F?  I do not see a dial.



Also I just got a notice of Ticket Value confirmed after 5000 nonces..   what does that mean?  - it looked to be on the R909.

Tiny knob in the corner, same as all other Gekko sticks. Slight clockwise turn.

Ticket value confirmed message is a leftover from some early testing. Just means we understood the format of the ticket mask register assignment correctly when we reverse-engineered the protocol.

Thanks Sidehack.  The stick seems better now but just a little slow compared to the others.  I will tweak the tuning.


Here is a video of the blinking lights.  You would not think this would generate that much heat, but so far it is enough to raise the overall temp in a 500 sq ft room by 4 degrees F.  That corner went from 72 - 73 degrees to 77.7 degrees.  However the HP Power supply and the  USB hub power bricks are also putting off some heat.

Got my R909 delivered today and got all my miners going except the R808 I got off of ebay appears to have pooped out. It was working then got stuck on Found 0 Chips..
...
Check it's not a software version issue - i.e. if it was working before, use the version of software from before just for the R808 and see if it's ok.
I've no idea if the R808 works with the current code.
I've run R909, R606, CompacF, NewPac, 2Pac and Compac on the new version (and you should use the new 4.12.1 version for those six)

Got my R909 unit yesterday.

It was equipped with an Artic F8 fan, that has a good airflow : 52.7 m³/h at 22.5 dB
Replaced by a Noctua NF-A8 PWM : 55.5 m³/h at 17.7 dB
Are you sure that you got the PWM fan? If so, it is now running at 100% fixed fan speed, since the R909 only outputs a 3-pin DC fan signal and Noctua PWM fans default to 100% fan speed if they get a (any) 3-pin DC fan signal.

@sidehack does the R909 have any fan speed control at all or is it just outputting a fixed 12V? In that case, it wouldn't matter (at least in case of Noctua fans!) which type we choose.

I need to replace my fan, too, since I find it too loud (at least the type of noise it's making is annoying me, somehow).

Are you sure that you got the PWM fan? If so, it is now running at 100% fixed fan speed, since the R909 only outputs a 3-pin DC fan signal and Noctua PWM fans default to 100% fan speed if they get a (any) 3-pin DC fan signal.
Yes, I confirm I bought the PWM model. The PWM part isn't important for the R909, but it is the 80mm Noctua model that has the most airflow.

I see, that makes a lot of sense! Only one question: the pin header outputs constant 12V? So, no control at all even on DC (3-pin) fans? Because in that case, I'd get the PWM, too. But if it meant losing fan control, I'd prefer an actual DC fan whose RPM can be controlled by the miner. No reason to 'over-cool' the hashboard, if there's more noise reduction to be had, right?

It seems the miner only outputs 12v, with no control on the voltage.
You could use the Noctua NA-FC1 (link) to control a PWM fan.

I didn't play with the fan speed, because with the Noctua NF-A8 PWM, and at 525MHz, the heatsink is at 55°c; you can barely keep your finger on it. You need the fan at full blast to cool it properly.
You'll probably need to lower the frequency, to be able to lower the fan speed.

Yep. Just like with the R606, I didn't put fan speed control on here because the fan's quiet enough even at full speed to be pretty unintrusive, so why bother with less than full speed if there's probably going to be a heat/efficiency penalty?
