add another vote from me to Spondoolies - very impressed with their equipment, service and support

Thanks, buddy - raised a request.

So it looks like I have a problem with one of my units - the fan stays on 80 no matter what I select in the UI. I've factory reset it a few times, tried on different firmware versions but no matter what I change the fan speed to it doesn't actually change the fan speed. I even looked and the mg_custom_mode file via SSH and it reports the same value as what's in the UI.

Not sure if it's the fan itself ?

I don't really want to open the other units and take a fan from another to test this

Nope no problems. I run 3 off 2 evga 1300w psus and the other 2 off the evga 1600w.

Probably going to move them into my parents garage for some cold and also to get rid of the fan noise in my house.

So I grabbed another one:

Thanks for sharing, trying your 1.2 th/s settings now .

heat is my enemy at the moment but I just will not put the fans on more than 30 !!!

I wouldn't remove the bottom metal stand - it keeps the boards firmly in place. Thinking about changing the stock fan though, the noise is driving me crazy now with 4 units

I'm using different voltages as loop 4 always seems to run hotter than the others, so I typically run it a bit lower than the rest

start volts:
1: .68
2: .66
3: .68
4: .63
Max Volts .685
max power:
1: 180
2: 180
3: 180
4: 150

They hash anywhere around 1275-1350Gh/s

I have an EVGA 1300w plugged into 1 and a half SP20s. that pulls about 1100w. The 1600w is plugged into the 2 remaining PCI-E sockets on the 2nd one, the 4 on the 3rd and again 2 on the 4th. That pulls about 1400w from the wall. There are only 9 PCI-E sockets on the 1600w PSU

I think I'll swap out the 1300w and get another 1600w, then I can power all 4 across 2 PSUs leaving about 2-300w spare

The unit on the left is a tumble dryer !!

It's a shoe rack turned on it's side

Will be wiring these in tonight:

some SP20 pr0n for you:



got an EVGA 1600w PSU sitting at home waiting to plug in - I think I'll need another PSU of not massive wattage to get all 4 going

Got 1 SP20 from a UK seller. Took advantage of the mining farm of 3 with free shipping, hopefully I'll receive it soon ! (UK based)

all good. So good in fact I bought a few more

I just ordered one, looks like a good idea. Still waiting for my activation...

I actually really like these
