my understanding is that the SP31 is limited to 1250W per emerson1200 if its on 208V power?
looking to squeeze some juice out of it to get past 4.7TH with 50C temps on the backside

My two SP20's are in a my small warehouse with people and phones in it. They pleasantly run all day with a fan speed of 30 with similar under-clock settings to what you have shared, Philip (and thank you for that!). I haven't tried 20 because I've been content with 30. They purr along at 1330 and 1375, the 1375 on less power too - just a more efficient machine. The past few days I have cranked the power and fans up when we leave for the day, and back down to the above when we return in the morning. The over-clock versus under-clock is moot in the recent hashing economy.
However, speaking of over versus under clocking, I did some maths the weekend before last, when BTC was at $375 USD. I figured then, that from a profit standpoint, if your power costs were below $0.135 kw/h over-clocking made more money. At $0.14 kw/h, and above, under-clocking was more profitable. If I recall, I used 936 kw per month for OC, and 518 kw per month for UC.
The SP20's dropped in price today because I bought three more yesterday. You're welcome.

I have had this happen more then once to me. Ice fury usb sticks killed me and gridseed blades were bad.
But in the case of sp20's My timing was good. all six are mining now during the paycoin rush. Oh I tried 1 firmware update and set the fans to 20. pretty nice
Hmm... I don't see the newest firmware in the Firmware Upgrade page though. "Latest available firmware version: " is empty.

Don't feel to bad. I have one from the first batch and pricing that's the slowest out of the four I have.

Maybe a naive question.
What is stable working voltage (UL?) or vlt 1 or vlt2?
The suggestion is to set the starting voltage to no more than 10mv below the stable voltage.

I've experimented with hacking the sp20 to fan speeds below those supported. When the device isn't overclocked (0.66v max) it seems to run fine at 20% fanspeed without overheating despite ambient temps today being in the high 20s. Noise is always an issue and this helps a little.
could you pm instructions or a guideline for this?
@ spondoolies-tech
a 20% and a 30% option are really good for this gear if you can put these in a new firmware please do so.
I have 6 units now all with low clocks. I would go for as many as eight if I could do lower fan's via your settings page.
My lower clocked machine are around 620 watts
1189 gh
this runs on a seasonic 760 watt plat psu and it is pleading with you for a 20 or 30 % fan firmware upgrade
I second this request. Fan setting of 20 and 30 would be great.
Fan speeds of 20 and 30 are available now. Firmware version 2.5.33
I will wait just a bit to do them. Sat the 21st comes to mind.

Are we seeing a Happy Hanukkah sale today?
Happy Holidays to everyone at SP Tech!
That would be very nice!
I have 6 If I get a few more it would enough for a Menorah!
http://en.wikipedia.org/wiki/Menorah_(Hanukkah)
and they did it a sale 659 usd !!!!!!
http://www.spondoolies-tech.com/products/holiday-special-sp20-jackson-shipping-from-stock
I've been looking at diving into BTC mining for a while now. I have rigs for altcoins but not BTC. With these SP20s in my home, where I pay $0.10 / KWH can I profit at today's price? Or do I look at this a n investment, hoping the price of BTC rises long term?
OR
Should I stop looking at the price of BTC in USD and just worry about amassing BTC?
Vague I know, but want to know what you guys think.
Thanks.
use voucher $50SPECIALOFFER for an extra $50 off. only available for 48 hrs.
happy holidays!
Thanks
I went to pay for one. I want it just to play and learn BUT it requires BTC or Bank Deposit. I wanted to pay by credit card or PayPal but do not see these options listed.
If you are in the UK, i may be able to assist. PM me if you are in the UK.
Canada. I'm going to send payment through my bank if they can figure it out.
ah OK, no worries, best luck with it.

At 10c electric, you are looking at 6.6 months to breakeven if the difficulty never rises (it may be static at the moment but lots of new hardware will be out before long), and that doesn't include the PSU if you need to buy one.
Use that as a starting point for YOUR decision as there will be plenty of varying opinions of what to do.
Thank you. I'm going to get one and let it mine, hoping for future payback on the price rise. I could just buy 3 BTC and sit on them but that is boring for me.

Got my first SP20 
It seems like a lot of fun. i am trying some settings I have seen around, but chips seems to throttle back at 80 fan speed.
I have seen low wattage setting, but was thinking to get to 1.5Th at 1000W (I am currently setting it up on evga 1300)
Is this doable or should I just shoot for 730-800W and 1.35-1.4TH?
