i will try my luck with my 2 r909 pod miner, only i would have to know how to adjust the rotations of the noctua fans ...

Good luck!
The fan header on the R909 doesn't seem to output a fan curve so whatever you plug in, will run at its max speed. For the NF-A8 PWM, that should be 2200RPM.

You could plug in the included (with the fan) low-noise adapter that reduces it to a fixed 1750RPM but then the airflow will be less than the original fan so I'd be very careful with temps.

Hey kano, I'm running 700MHz for around an hour now, without changes to the voltage screw and the NF-A8 PWM running at 2200RPM. Seems stable and good so far. I'm finally getting over 2.5TH/s (that was my goal), so I guess I beat you, with stock voltage! Grin

I see, makes sense!

Quote from: kano on January 07, 2023, 12:09:04 PM

So I tried to do something that I'd not suggest anyone else to do Grin

Of course try it if you really know what you are doing and have a 5kRPM fan, high quality power and are using linux

The aim was to see how fast I can get the R909 going - and I've got a record so far, we'll see who can beat it Cheesy

My production R909 has one chip not as good as the other 5, so someone with 6 perfect chips should be able to beat it.

Anyway, I put in a 5kRPM fan, set the blue screw close to maximum, set 5 chips to ... 725MHz ... and the dodgy chip to 500MHz.

Hey kano, I'm running 700MHz for around an hour now, without changes to the voltage screw and the NF-A8 PWM running at 2200RPM. Seems stable and good so far. I'm finally getting over 2.5TH/s (that was my goal), so I guess I beat you, with stock voltage! Grin

Just to make sure: worst that can happen when aiming for too high clock speeds is that it crashes or returns faulty hashes, right? Or is there any 'risk' to pushing the overclock as long as the voltage screw is not touched? And the error rate is displayed through those Java API commands, right? The only way I've checked my error rate so far was the log printed when killing cgminer.

Nice setup! For what it's worth, you could run multiple cgminer instances all on a single Pi, or are you getting issues when too many USB devices are connected?

Essentially with all of the fans being plugged in I was running out of usb ports. The original setup for Rig 1 was running stable as it was so I didn't want to change it. Given I have many Raspberry Pi and other Single Board computers laying about, I figured I would just spit it into two mining rigs. That way I could relocate one if need be. Plus test mining against different pools to see how things went. Right now it is a little cramped in that one area. With Rig 1 I have a keyboard and mouse connected. With Rig 2 I am forcing myself to work it remotely.

They really are! It seems to me like sidehack did good work on the thermal design. Super beefy heatsinks on both sides, with nice channel for the air, all in all running great.
I've ran 600MHz for over 48h without touching the voltage knob, and got no anomalies in error rate or anything.

Now testing 650MHz just using --gekko-r909-freq 650 on all cores, stock voltage.

Thought I would provide an update with my setup. I got the 2nd R909 and 5th Compac-F up and running on a 2nd RPi4. I have been mining ViaBTC pool with the rig setups below and the 24hour mining results are: 10-Min Avg. HashRate fluctuates between 5.5TH/s and 7.5TH/s. All is working great and the R909s are AWESOME!

I've been gradually increasing frequency, without playing with the voltage knob, and so far I've reached 600MHz. Getting 2.3TH/s out of it. Pretty amazing!

In this overview, what frequency is shown when a device has multiple chips? On your two R909's, I can spot one at 500MHz and one at 687.5MHz. Is it the average?
I guess so.. (725*5+500)/6 = 687.5

I'm going to need to dabble with the Java API and individual frequencies, too. Right now, just using --gekko-r909-freq 600 and restarting the process when trying another setting.

among other things replace the fans against the noctua ones Wink

For what it's worth, do be aware that Noctua does not equal absolute silence. So far, their most quiet fans in my experience are the A12x25, which even at roughly half speed (1000RPM) provide ample cooling and static pressure for my application while being almost silent. Of course, they don't fit this miner.

Other Noctua fans however, need more RPM to cool properly and are definitely audible. Even larger ones like the NF-A14 PWM.

I installed the NF-A8 PWM in the R909 earlier today and it sounds slightly higher pitched (at full 2200RPM speed) than the stock Arctic F8 at 2000RPM, although the sound is a bit quieter and more pleasant; the F8 almost sounded 'rattly' in a way; some kind of frequency was probably spiking higher than the others.
Right now, I am running the Noctua with the included LNA (low noise adapter) at 1750RPM and that makes it almost silent from a few meters away. However, it results in a bit less airflow than even the stock fan.

For now it works without issues at 525MHz and a bit over 2TH/s, but I definitely need to check my temps somehow.

R909 seem to be a bit particular about power, yeah. The fairly cheap brick on my linux laptop is noisy and I had to replace it before it'd detect the R909 over USB. Sometimes it'd load up and work for a few seconds then drop out again, but most of the time it just doesn't work. I ended up in a pinch just using a second lab PSU for the laptop, just like the one powering my test R909, and it's been running beautifully at 600MHz for the last day on that setup.

Didnt have the problem on a Pi controller, because it was running off the same clean power source as the pod. Low quality power for either the pod or controller could cause ground loop noise issues that throw off the USB signal voltages and make for a poor connection.

Yep, once the power problem has been solved, it is hashing beautifully on 600 Mhz at room temperature:

(5s):2.887T (1m):2.433T (5m):2.418T (15m):2.422T (avg):2.401Th/s

Now measuring for a couple of days how much power it sucks before installing it in a solar system. There it will work in constantly 15° Celsius, so looking forward on how the performance will be then.

Mine with 6 good chips is sitting at 2.4T flat at 600MHz, blue knob about 1 o'clock, pulling 104 watts DC with a stock fan and pretty low HW. My old laptop craps the latency timer at any higher MHz but if I can get the Pi back running I'm gonna try to beat that record.

The BM1397 chips have a significant temperature coefficient, which means that they pull noticeably more power as they get warmer. Nobody at GekkoScience will be offended if a tuner or enthusiast upgrades the fan, as more airflow could mean reducing power consumption by 5-10% just from maintaining lower temperatures. These units take a standard 80mmx25mm 3/4-wire 12V case fan.

Speaking of this: is there any way to read out the chips' temperatures?
Or would we need to manually place a thermocouple and monitor it that way? I'm asking, because I replaced the stock fan and now I'm not sure whether it's getting too hot.

Okay, seems it is a power problem. Had to find a more stable PSU for we have here massive problems with the current in our house. Hope it will be better once I put the device out of the testing environment in my house and on a solar device.

[2023-01-06 13:25:53.694] GSF 0 failure, disabling!

Frequency was originally set on 450 in my configuration. Changed it to 400, but still the same result.

Rebooting the Raspi didn't change anything.

edit:
Now, since a while, I only got this message:
