Im having a problem with my SP20 that I just bought off of ebay.
I have tried getting my SP20 to start and it wont. When I turn on the power supply the fan will come on run for about 5 seconds, then shut off and the yellow light will come on. Then the yellow light goes off and the fan comes on again for about 10-20 seconds then the fan shuts off again. The yellow light then begins blinking 6 times every few seconds. The ethernet lights are both going but it is not showing up on my router and going to myminer.io shows me nothing.
I have tried to sd boot it = nothing
sd reset = resets but then when I take out the sd card and restart it.....nothing
......I even tried the blow dryer trick......nothing
The old owner has been a huge help trying to get it going but so far nothing
Any help would be majorly appreciated!
What PSU are you using? Model and watts.
I would start at looking at that. I never had to do the sd boot luckily.
Im using a Thermaltake Toughpower Grand 1200W
Garbage psu multi rail so
Here is my guess.
One rail is 36 amps that is good for one pcie plug not 2
Second rail is 36 amps that is good for one pcie plug not 2
Third rail is 20 amps that is only good if your gear is set to 200 watts per pcie plug
So if your gear is set to 200 watts per pcie plug you can only do three plugs not four.
I would connect two pcie plugs

It should start on one of those patterns
With 3 rails of 36 36 20
You could get it to work on careful setup and big under clock.
Since the most a 36 can do is 18 x 12 = 216 watts. A setting like 150 watts would be okay.
So .61 volts. And 150 watts would be good.
But you need to start it to downclock it to thay
