Unofficial Spondoolies SP20 thread

[bgibso01]

I cannot get API working

when I do

SSH to your miner
vi /etc/cgminer.conf
editing {"api-listen":true,"api-allow":"W:192 etc","pools":

the cgminer.conf seems to be overwritten with default 127.0.0.1 after restart...

any Idea?

Yeah, your using the .64 or later firmware.  On that one you need to change the cgminer.conf.template file instead.

[lulu2003]

thank you!

2 further questions:
when trying different fan speeds, what temp in degrees c should not be exceed?

Where do I find the "SP20 User Manual" that is referred in the quick guide?

i'd say 40 degrees c but i'm in a c,c,c,cold place .

snowed again last night

this thread is as good as any, better even.

tried that but

neither

{"api-listen":true,"api-allow":"W:127.0.0.1,192.168.1/24","pools"

(after cgminer restart it inserts a Backslash before the slash???)

nor

{"api-listen":true,"api-allow":"W:127.0.0.1,192.168.1.0","pools"

works.

[aclass]

i don't have the miner on hand so i have a couple questions

1. what is the exact model and specs of the sp20 fan: model fd121238ub
12V how many A
RPM? 4600
CFM? 212.6 max
db based on specs? 61.5

2. what will happen if i add a second fan in front of the built in one without removing it?

thanks

works.

Try: "W:127.0.01,W:192.168.1.0/24,W:192.168.1/24"

I had to put both versions in my config to get it workin... yeah, its weird, dont know which one really works haha

So, why does every day that goes by my SP20 keeps clocking itself a tad lower ... losing like 3GH-5GH/day ... and never goes back up? ... unless I restart mining...

My guess is high clock high settings.

Or your psu  is getting older.


But if you are set to hash at 1200gh using 600 watts with a stud psu then I don't know what to guess.

settings ?

210w limit per board, voltage start 685, limit 699, temps never hit over 105c

No, sometimes it does. Don't have it handy to show right now. Wiggling your settings by 1-3 mv sometimes helps with this, but I am only talking about an underclocked miner (1.2-1.3Th).

yeah try doing them all just a little power.

say 200 watts

.682 all four

and .691 max.  

  I think you are just touching a bit warm for that machine thus the small drop off.

I can move all six machines 20 gh or so by open and close of the door in the photos below.

The gear is a bit sensitive to temps.

I highly doubt its temperature related. All the time, all ASICs cept maybe 2 read 85C, 2 of them ... some of the time are between 105C ... those dont get throttled down tho, its the cooler ones that seem to .. I dont get it.

It seems like some of the voltages are getting raise and clocks are being dropped to keep under 210w, but that makes no sense... why would the volts get raised a tiny bit over the course of days, if the chips are already stable (no hw errors) ... etc...

could be the psu is dropping the 12volts just a little bit with constant 24/7/365 use.

and the sp20 is adjusting for the voltage supplied.

 I still would try just a little lower on all settings.
 maybe keep the watts all at 210 and drop every volt setting by .004.

The more I use the sp20's the more they remind me of gpu mining in the sense that every gpu is a tiny bit different from the same make and model.  Also in the sense that tiny adjustments in volts can make a world of difference in preformance.

Contact zvi @ sp tech support;  I had a SP20 that did the same, and they RMA'd it for me.

It is not you; something a little odd with that unit

I dont wanna go through that hassle n downtime, Ill just manually reboot it every once in a while if thats what it takes ... or make a cron script or something... I ono

Mine tend to lose a couple-few Gh/s a day too.  I use the new(er) 'Restart miner if rate below' on the settings page to automate your process - no cron needed - the value is in Gh/s.  If mine drop below 1300, for example, they restart.

I was thinking about that, but thats a really aggressive use for that setting. I prefer to use that setting if one of the ASICs stops mining all together or a majority of them. But, Ill ponder it further ... if it ends up bothering me enough lol!

some SP20 pr0n for you:

>snip image<

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

It has 14 PCIe plugs, right? So, you need just another PSU with at least two plugs, but i would just get EVGA 1300; this way you can downclock to ~700W/1250-1270Gh.
However, if you want to downclock, the trick would be how to downclock them with just one or two PSU.
You would have to do it one by one, bring to stable hash, then switch off and do another.

what is to the left of them-it looks interesting.

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 !!

What speeds are you seeing?  I'm running two SP20s off of a single EVGA 1300G2 and getting 2.4TH/s between them without issue

[lulu2003]

do you really care?
3-5 Gh/s per day are roughly 2-3% per day. E.g. pool luck is changing at a much higher rate or width.
Reboot every 1-2 days or try that trigger mike9 mentioned, no need to worry I think. Worry about you power rate $/kwh related to current BTC/$ if you need to worry
