Unofficial Spondoolies SP20 thread

[takagari]

I have 6 of these coming, I'd like to run them at the 1000-1100 watt range to optimize my server psu's.
I was considering running 4 off 4000Watts,

But that taps me at max, so was thinking of running the spondoolies, 3 on 4000 watts, which leaves me space to crank them right up if needed.

Maybe even share a pir of ants with them that I can take offline.

Should I max my 4k or leave space to crank them if it's needed?

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

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?

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 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 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.

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

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

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.

I try with few Tplink Usb`s, no one get recognized.

Probably miners controller support some of wifi chipsets, but not all. so we just have to find correct one.

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.

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'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.

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

Its not that connector, thats a standard VGA power connecter found on graphics cards, its too big for the spondoolies socket.

I know, I bought one months ago.

[takagari]

Anyone know where I can get the screws for the outside of the sp20?
I'd like to secure them to my racks. And the holes are perfect for it.

You might try the primary Spondoolies thread for screw specifications and such:

https://bitcointalk.org/index.php?topic=521520.0

Armed with those, I would go to my local hardware store. You could even take the SP20 with you, though that's kinda "over the top" in terms of providing them the example you are trying to match.

So I've been mining for a few days now with my SP20 and I've noticed that I get a lot of stales. Is this normal or something I need to look at? (I'm very new at this)

Est. Speed           Accepted Shares          Stale / Dupe / Other        Last Share
1,480.63 GH/s   99,474k (99.82%)   171k / 0 / 4096                0:00:06   

I've read that stales should be a very small percentage. This is on BTCGuild BTW.

well 99474k to 171k is like 581 to 1  which is 99.828 percent not so bad , but

btcguild lets you set your workers speed.  you may have a shit setting for speed.


try 1024 first

in not try 512 or 2048

[Molocko]

I am planning to get a few of those.
I don't mind the noise generation because i will probably use them in a empty room far of the bedroom.
Can't wait to start mining

Has anyone found a 120mm fan they put on the other end of these and find it helps at all? although sucking is one option, I'd think a two fan approach would drive even more airflow?

why do you need more air flow?  are you looking to run this at 1600gh+  ?
