Topic: question about s17/s19 hashboard configuration/operation (Read 123 times)
If what you've done is, as you've said, unplug two boards and run on one, then no what I suggested is not what you're doing.
thanks guys, good info there wndsnb, and yes sidehack, that's pretty much what I have running now, its not that good, around 4.2TH for just over 400w, I cant balance the voltage and frequency for a stable rig.
I will still keep an eye out for a newer system tho, maybe a s15, and mod that, still twice as efficient as a s9.

If you do this, you'll want to block the airflow around the board. The heatsinks rely on high flow to keep chips cool so if your air is going around the board instead of being forced through the fins it'll overcook.
You should look into braiins or vnish firmwares that allow you to adjust the voltage and frequency of the S9. You could get a unit down around 400W and quiet but still operating well upwards of 5TH. Better than one board at stock speed.

All the S17 series (normal, pro, +, and E) have 3 hashboards and they will operate with fewer if you unplug the data cable for hashboards you want to disable. S19 should be the same although I haven't actually seen one yet.
For a plain S17, 1 hashboard does 16 to 19 TH at around 45W/TH, so 720W to 855W per hashboard.
Not likely to find any at reasonable prices though. And be warned that the 17 series had a lot of quality control issues so high failure rate.

so, this might sound weird, but allow me to explain a bit first, I cram miners in where ever I can, at the office, in the shed, even paid hosting, so I look for different solutions to my issues.
so at my home/office, I want small power (wattage) BTC units, so what I have done is acquired s9's, and unplugged 2 of the hashboards, so it runs on one, then I can turn the fans down so it runs at around 400w, and I get winter heating, so all is good, so I need an upgrade, but how many hash boards are in the s17/s19 units, and can it operate with only one hashboard in it? how much hashing power is in one PCB? and roughly what would be the power draw of said board?
I was looking for under hashing units, as they come cheaply sometimes here, and wondered if they will fit the bill for next years winter.
any info on this would be good, everyone is talking about getting the best from these units, I actually need the worst from them lol.
thanks.
