How work after do it ?
How work after do it ?
I'm looking for a controller board if anyone have one.
I could buy one that is working but doesn't boot all the time (Full speed fan + Ethernet port on).
PM me !
thanks

Any of you guys knows of a single PSU that can drive the SP20E?
Seasonic X1250 (Gold) or their 1200 watt Platinum unit should work.
Many folks like the EVGA 1300 G2 gold unit, though it's a hair less efficient than the X1250.
The EVGA tends to cost a little less than the Seasonic gold is probably what makes it more popular.
I tend to be conservative on PS usage, never run them real close to capasity, so my pair of X1250s running one Antminer S5 and half of my SP20 each is definitely overkill. 8-)
The G2 is actually the one a hair more efficient, and proportionally more efficient if you run them both at the same draw, because of the 1300's higher rating, for instance the x-1250 will go down to 87.x% at 1200w fed and the G2 at almost 89%. The warranty is better as well.
But since they are so similar in term of performance, i'd recommend going with the price here, but definitively favor the G2 if its same price or cheaper. The extra 50watts rated is good here for a single psu running a SP20 too.

Personally, if i had nothing and i had to do it with a single PSU, i would buy and use a EVGA G2 1300w. Otherwise i would get 2x 750/850w EVGA G2/GS for cheaper or the same price.
The Bitmain's one would also work, but i have no personal experience with those, i don't know how clean the power is.
It also depend at what speed you want to run the SP20 but i assumed you'd be feeding it 1000-1100w.
I got dual 1,200 WATT PSU Running mine now but I am not concerned about power costs for them I simply want to whore them out and run them as fast as I can. Within spec of course I am not out to kill my hardware.
Then, you're fine. I use EVGA G2/GS not because of efficiency, but because they're rock solid, clean, stable power, doesn't burn out my hardware.
The 91% efficiency is just a plus, which is nice since it generate less heat in my apartment. Also the 10/7years warranty... its nice.
Definitively worth protecting your hardware, imo.
use another fan and if it's doing the same, it's the controller
if not then you did something to the connector and/or cables

Good point thanks

I had to play a bit with one of my SP20 fan... it seems that i can't control the speed of the fan anymore.
What's the default speed ? It looks like 40 or 50.
I set it to 10% or 100% ... nothing change.
Either I damaged the connector or I don't know.
I already try to ssh and edit the file to check if it was set at 30% and it was.
I re-installed the firmware also => 2.6.14
Any idea ?

...today after i restarted one of them after tweaking voltage,yellow and green lights didnt light up at all,so after alot of differenet tries to recover it with switching power cords,restarting,sd card rebooting,and so on,i concluded that my controller board on top of the miner has probably gone.So i replaced this board with other from different miner,lights are up and miner starts normally,so my question is can this controller be repaired or i shouldnt bother...
This is going to sound crazy, but I have one miner which behaves exactly like this after every power outage (fan spins and Ethernet link lights, but no yellow/green miner LEDs light and it just sits there doing nothing). I managed to get mine working again with a hair dryer. Chances are it will not work for you, but it can't hurt to try:
1) You will probably need to use a SD boot card (not recovery)
2) Before powering up the miner heat it up with a hair dryer on the high setting for 60 seconds (blowing it into the air intake is fine)
I've done this with mine three times now and each time it started right up. Like I said, it can't hurt to try it.
Whoa ... this morning I had a ethernet switch problem and none of the mining gear could connect. When I fixed the problem almost all of my SP20's were exhibiting the "no lights but ethernet problem" and refused to boot. Repeated power cycles, waiting, power supply swapping, even disassembly and cleaning .. nothing worked.
However I found this post ... tried it out ... I almost couldn't believe it ... it worked for every single machine ... wtf! I've had these machines since January ... I certainly don't recall this being a problem back then. Actually come to think about it ... maybe it was a problem, I have had some odd "doesn't want to start" problems in past that have all "magically" resolved themselves.
Perhaps it has been this heat issue the entire time?
Hi. It actually makes sense. A hot machine stops in a presumably colder environment with some moisture in the air.
Moisture accumulates on dust (my SP20 trapped quite bit of dust during operation, unless you use "dust off" religiously and thoroughly), now you have wet dust which probably affects electrical characteristics, hence miner not starting. Using blower simply heats up the "dust" back to the initial state (dry), miner starts. I had similar experience, did not use heater, just blew a fan on it for 10-15 min and it was able to restart.
In any case, glad that things worked out for you...peace.

Hi,
I have an SP20E unit that when it loses power, it loses the mining pool information and the voltage/power settings go back to the defaults. This unit is run very conservatively, with a total power draw of about 500 watts. Any sort of battery powered memory in these systems?
Any idea of what's going on?
TIA

it can be possible that it looses the internet connection check your cables, router, etc etc, only had thhat problem whit internet, it looses power and reset volts.

I will try re-do cooler, If chips will defected, I will write you PM, Ty
If anyone is interested, I have an SP20 ASIC board available for sale. Message me if so inclined.
Looks like chip 5 is running very hot, might need to pull the unit apart and re-do the heatsink or thermal compound on it.
Hello,
I have problem with one SP20E.
After 10 second of mining miner write about problem:
LOOP[2] OFF TO:0 (test serial failed)
4: disabled (serial problem)
5: disabled (serial problem)
could some one help me? I tried change PSU, nothing to change
After reboot miner give these, all is OK except of 5th board have temperature attention to 125c, but board have only 52C.
LOOP[2] ON TO:0 (w:2)
4: DC2DC/1/:[vlt1:660 vlt2:661(DCl:794 Tl:794 Ul:738) 67W 101A 44c] ASIC:[ 85c (125c) 800hz(BL: 800) WN:0/0 (ffffffff) (E:193) F:0 L:0]

i can't seem to get my miner above 1.1 thz.
Asics showing 125c all the time, what should i do ? i have repasted it recently might have done a bad job ? .
Temps are around 38c / 69 c.

post your settings plus readings from the asic stats page
here you go, i managed to get up to 1.3 but i would like to get it to highest hash rate possible, power is not a problem, it's currently on a 2000w 80+ server psu so there is power enough for it

You have 47C at input-this is way too high. Temp in the room has to be at or below 35C.
This might be your main problem.
You can also try to decrease voltage to chips in a controlled fashion (in Settings pane): move down in increments of 0.005V and adjust both start voltage AND max voltage at the same time.
My settings are:
Starting voltage:
0.642 for all four
Voltage limit: 0.647
Max power-sometimes you'll need to adjust individually, but you can start with 170W for all four (in my case I ended with 165, 153, 165, 164, but after a fine tuning)
With these settings AND with 30C temp you can also adjust fan speed downward (I have fan 10), but you should only do it AFTER your ambient is better.
