So the SP20 fan is not connected to the board with a standard 4-pin PWM connector?  If so, that's kinda Apple-ish.

I'd be interested in knowing if this adapter worked as well. Have a few 4 pin PWM fans I would like to try to experiment with in the SP20's.

Has anyone tried one of these pmw fan adapters to see if it works, or does the sp20 have a different wiring solution?

I was thinking about using a delta I had lying around and seeing what difference it makes for noise, but I would like to keep the wiring clean.

I ordered 3 different wireless cards that were listed by spondoolies and neither one gets detected by any of the sp20's. I had to get tplink mini routers from microcenter and they work just fine wirelessly now but its a jumbled mess of cables now so a usb adapter would be much cleaner. Also i only see spondoolies say wifi has been turned on for testing with sp10's in the test firmware....i know the wifi button is shown in the admin page but its hard to believe it does anything when 3 exact cards gets no results. I just used them in other machines ne way so no biggie i guess.

I asked spondoolies to give us the ability to add files to the miners and or give a package manager for the miners so we can add our own wifi drivers and the rep replied back with "thanks for your suggestion" so im guessing that means no. If they gave us root access to the miners idk y its frowned upon to give us a dang package manager. They promote the recovery image guide they posted so i dont see the harm here at all as long as they state this is at our own risk and we r responsible for recovering the image if we mess something up software wise.

On a side note can someone pm me a link to where spondoolies explains their changelog between all of their firmware revissions?? I tried looking but only find changes for the main updates and not the test updates so idk what changes were made from the last test version to the new one.

I believe John K was attempting it, but I never heard if he succeeded.  I would also like to know, out of professional curiosity, if this has ever worked in the wild.

sry, maybe a lil out of context but has anyone at all ever got the wifi to work?

with price of coin up to 250 a bump up works.

 I bump my machines up and down from 600 watts to 700 watts when I go over 250usd a coin.

 but each person has different power costs, total  power they can deliver to the gear,ways to deal with the heat. etc

I agree about the 1000 watt range, but effectively if I tap my PSU's out at that, than I could screw myself when I see a 800 dollar bitcoin and want every hash I can get.

That being said, these little psu's have been known to run 2400 watts a piece. So maybe I will clock them at 1000watts, put two per psu and just overclock with extra cooling as needed.

I have 3 of them running where I get super cheap electricity right now, all at around 1100 watts and they're averaging 1575, 1590 and 1610

I am looking to sell you the idea of 600 to 800  watt swing ,

 but with 7.5 cent power  700 to 900 watt swing  or 800 to 1000 watt swing  makes sense.

My setup does not allow for me to do 1000 watts with ease.   I go from 600 to 750 watts per sp20. 

at 600 watts  I get about 1125 gh

at 750  watts I get about   1325 gh


 there are more then one person using 1000 watts.  my guess is 1000 watts puts you in the 1450-1500gh  hash rate.

I pay 7.5 cents Canadian.
Power supplies are cheap, So I like the idea of having room too go from 800 to 1100 or so when the price increases to make it worth the extra hash.


What would I see for 1000watts at the machine for hash?

Seriously You're kidding right
I have contacted support several times and I got nothing for it. I asked for the SSH login and I wasn't even told it was root/root. That should've been in the documentation.

Why can't tech support provide a written troubleshooting guide I can follow

I also requested RMS to return the several DOA SP20 I received in my 15 SP20 order and I have not recieved that either.

Contact support@

Huh? What's a Minersource

On the SP20 Settings page it says
But when I search the ASIC Stats page the word "stable" does NOT appear. Where do I get this "stable working voltage (from ASIC stats page)" I'm supposed to enter on the Settings page

From Minersource?

I recently received 15 SP20s and I cannot get them all running. Several have the problem of dead or idle boards. Is there a way to wake them up and get them hashing or are they just plain old DOA   Below is an example powered by a dedicated Corsair AX1200:

what is your power cost.  the sp20's run really efficient in the 600 to 800 watt range .  once you want to do more then 800 watts into the sp20 the hash rate hardly goes up.

I would try to run 5 sp20's off the 4000 watts of power you have.

 I would send about 700 watts to each sp20 which is about 1300gh for each machine.

at 9 cents a kwatt or more this makes sense
