Have that not made any progress in terms of cooking towers yet? Idk, but why they have not made some sort of chamber which can help suck the Hot Air and recirculate the cooler one with the low cost of production and also maintaining of the same.
I am now seeing water cooled CPU and mining equipment as well which is mind blowing. Anyways they cost Far more than the conventional one.
Since you are discussing about the oldest player devices here, I could imagine more run over cycles until they break itself.
Topic: What to do with all the old s-9s. (Read 2591 times)
I'm not really sure I see any reason to mod the s9. With apw5 and braiins os+ the s9 is way quieter than my r4 by running the stock fans on auto and the power >1000. I watch television in a room with 2 s9 at 700w and auto fans running >20%. The AFB1212SH fans actually run at a higher rpm and seem louder to my ears at the same settings as stock fans.
The afb1212sh fan pulls a lot less power IIRC

I unlocked this as there has been some interest in s9 mods.
setting these up and locking them
Ooh, firmwares. Maybe in early December I'll have time to test out some of that, rig up S9 space heaters for the new shop. I've seen BM1387 go below 70W/TH at the chip and landing a couple machines below 80W/TH wall would be nice.
If you don't want crazy hash rate then you can go below 70w/th but we are talking really low hashrate.

at davef i have this miner in clifton and i have a s 7ln
i am going to clifton mon or tues after thanksgiving maybe we can get together.
i also have a avalon a721 working.

I'm good on HW at the moment.
At the moment I have two customers who are getting out of mining and they are just leaving their gear behind as it does not pay to ship. All of them older S9 units, all (most?) with some issues.
Probably going to see if I can mix & match good boards and go from there.
-Dave
Yeah, it works on I and J. I am not 100% about it working on the K so hold off on that I will confirm because otherwise you got to flash the board back to life and it's a major pain in the ass.
This is the instructions for the S9's https://asic.to/documentation/
Pardon the shitty language I have to rewrite it from scratch but I think I am going to re-write it for the S17 and T17 since the S9's are on their last leg.
There have been people that have gotten 2 s9's with 1 fan each running at 21th at 1500w off one psu. The autotune will be the saving grace for maximum efficiency.
Edit 4:
475 - 8.0 - 10 TH/s - 750 watt
550 - 8.2 - 11,6 ths - 950 watt
(78 waтт / THs)
631 - 8.3 - 13,5 ths - 1100 watt
(81 waтт / THs)
700 - 8.6 - 14,9 ths - 1300 watt
(85 waтт / THs)
750 - 8.7 - 16.1 ths - 1450 watt
(90 waтт / THs)
edit 5:
now is that with stock firmware or are you making it worth a little harder or less through software?

Although not nearly as efficient (or even BTC related) I just did something similar with an L3+
Just unplugged 2 boards (left the other 2 in) and it's a nice just about dead silent 250MH/s scrypt space heater.
Going to work on power and speed vs fanspeed and noise while playing with the number of boards but, it might be nice in the back room of the condo for the winter.
Makes you wonder how much gear we can keep running by doing this.
Going to play with an A721 next.

I am going to play around with it. Is it good with s9 s9i s9j? I also have some s9k
So the firmware I last uploaded to my thread in the software section. Also can be found here: https://asic.to/firmware-for-antminer-s9-ij-17-5-th-s-70w-th/
Can do 70w-75w/th at around 10th.

When I put mine together, I couldn't find the thick spacer that I had ordered. So, since I had a 2 pack of the thinner ones, I used that on both sides. I found the thick spacer sitting around, so I put it on. I didn't notice a difference either in noise, temps, fan speed or hashrate. So if someone was trying to save a few bucks, they get away with using a 2 pack of thinner spacers.

Brains would work well.
March 2019 may be good.
Dec 2018 works well.
I have run a single board from 2.5 to 4.7 th
Some settings did 100 watts a th
Some did 88 watts a th.
I only built one as most gear is in Clifton NJ not HOWELL NJ
I have a bad m10 that I am trying to get aboard to work. It would be a copy of the s9 idea.

yeah it will do 4th and 400 watts with one board.
if you have the older firmware from dec 2018 low speed does less and is quieter.

what about clocking it down with a firmware modification?
edit: voltage
Yeah, I think the Antminer PSU is actually louder than the AntminerS9 now, switching out the PSU makes it even quieter.
Yeah I use a 1000 watt Corsair. I have also used a 1500 watt Corsair.

I finally had some time to assemble this. I also found that adhesive backed insulation. I put it together as per your instructions and am getting 4.7TH/s with an 81 degree chip temperature. I cut the boards 10 1/4" by 4 5/8th" by 1 1/4" thick. I think my wedges are a little closer to the hash board than yours is, as my board was thicker. It seems to be working just fine.
Quiet right?
