Its the only option at the moment that is for a “lottery”.

Ahh i was referring to the S9. Not sure on the S17.

You can. Currently got mine set to 475w

I have some spares from a couple of S9's (13.5Th) that I don't need anymore.

4x 120x38mm fans (vary from 1.65a to 2.7a) so varying speeds but there is a pair of the same speed.
3x S9 V4.21m hashboards all from the same machine.
1x Bitmain APW3++ 1600w psu (with spare set of clean pcie cables)

Only down side is they were used in immersion cooling by the previous owner. I have tried my best to remove all the residual mineral oil (with quite a few cans of electrical contact cleaner) but some still remains.

Open to offers but only from UK residents as they simply aren't worth shipping abroad.

Cheers.

Thanks Artemis. I'll get another SD card.

Is it possible to switch the SD card from an existing S9 to a new S9 and have it work? Would it run with a current working autotune profile or would it sense the change of miner and redo the autotune?

Or would it be best to just get another SD card and do a new image?

HP Common Slot ones are the most useable from what ive seen. Ive got a couple i use (460 & 750w).

Got one sitting on the shelf in the storage room. No longer able to do anything because the company closed etc etc but still runs as much as it can.

Thanks for the info Artemis. I realised it saves the profile today (after numerous restarts for a supposed "dead" pool which wasn't).

Wish I could afford an S17 lol

These R606's are the best he's got so far, but judging by each iteration of miner he produces the next will be a lot better (if he makes a 500w miner, which I hope he does as my space heater project isn't that efficient, even for a space heater  )

Is there any setting which allows the miner to be identified as a given name say "S9 Heater" within the braiins OS when running an IP network scan?
EDIT: Found it in the "Network Interfaces" menu. Just edited the Lan settings on the green highlighted one and changed the "Hostname when requesting DHCP"

Also is there anyway to save a Power Tuned Profile somewhere so you can load is instantly rather than it go through the whole testing phase?

Will do. 

Thanks philip.

I was going to take it apart today and take a look at the current specs. Ideally a straight swap would be nice to one of the ones you suggested. It will definitely be around a 500w power draw, maybe less. It will only be a temporary thing as the end goal is to use an hp server supply with gekko breakout board and some custom cables (to keep them as short as possible) and make the entire unit as compact and portable as possible.

Thanks mikey. I thought i would ask here first just incase anyone has swapped for a quieter one.
Cheers for the dimensions and the cable length, that’ll be useful.

Anyone replaced the fan in the APW3++ Psu? Its now the noisiest part of my setup

Used the autotuning and specified 500w. It says its drawing 491w on all three boards  (527w at the wall).

Hi,

Anyone in the UK/EU have good condition 18pin Ribbon cables spare for an S9?

The three I have on a recently acquired secondhand S9 have broken latches so although they work, im not 100% sure about them.

Thanks.

Found a delta afb1212she in a drawer of random bits so going to give that a try which are similar to the ones you suggested philip, so going to give that a try.

I wont bother with the noctuas. I was grasping at straws thinking they might work but any sort of reduction in initial startup noise would be good.

Also I found that power limiting/auto tune setting and it gave me 6Th at 530w (at the wall) so not too bad really. May well follow your setup philip and switch down to a single middle hashboard with some added ducting either side.

Edit,

Found a similar 120x38mm fan rated at 1.7a (afb1212she rated at 1.6a) Both fitted and the initial startup is quieter it produces a whistle now but only until the firmware kicks in. Currently set to 500w power limt and still getting 6Th. Fan speed is AUTO is 1000-1200rpm (32%) keeping things at 80c.

Is there any way to remove the extra fan slots from the graph? Fan ID "0" & "1" are what im using but 2&3 read 0 rpm and obviously dont even have headers on the control board.

Ok so ive managed to acquire an S9 with PSU and got braiins on it. Now heres my questions (and apologies if they have been asked before).

1) how does it react to swapping fans, probably to some industrial noctuas 2000rpm?

2) Is it just trial and error to find the most efficient setting or does the power limiting autotune do that for you?

Thanks in advance.

Welll....... i know you’re busy with various projects so didn’t want to ask directly but yes. A Type C to Type C passthrough type UPS for a Pi4 would be damn handy.


I saw these but I would have to have it hanging around on a GPIO extender or cable. Not the best look really.
