2t for 500w? that's like ~2016
the stupid trend now is make big and bigger miners! stupid!
just make 2types of miners case, format... home and server! keep the standard constant and improve the hardware inside!
no +roi atm, not at this btc price!

I think I will just buy BTC in this case. Buy BTC and wait til it goes up, buy the next version of 2T miner that takes 500w.
ask DHL, that's the cost.
$119 shipping? Are there any coupons or discounts available to offset some of this?

$119 shipping? Are there any coupons or discounts available to offset some of this? It would take 5.3 months just to break even on this unit at 11c electricity.

How long is wait on SP20 to go "unfulfilled" to shipped?
I believe shipping is on the 18th or so.

Time to buy more hardware....
How are you sp30,1,20 buyers doing for ROI? meeting expectations? Machine performance? How is the cold weather performance? I know sp machines are loud so I would add to my shed farm (literally) ambient is -5 celcius right now and my ants are peforming better than ever in the cold +10% performance. Is anyone else getting similar results with Sp miners?

I still have my SP10's running. They are in a data-shed with ambient temp of 11degrees celcius. I have them underclocks at 833W max power and they run at 1.2TH/s each rig.
Couldn't afford SP30 / 31 but I do have dibs on SP20 (which will be mining at home)

There are a couple of bugs in SP30s that show up at temperatures below about 8°C. One causes individual ASICs to become nonfunctional and starts to occur around 8°C. It appears to be a hardware problem, and it affects a small minority of ASICs (about 1% or less). Spondoolies is actively investigating this issue. I expect they will be able to fix it for new machines, but it's uncertain whether they'll be able to fix it for old ones.
Another issue caused machines to shut down if the intake is below 0°C. This appears to have been fixed by firmware 2.5.13.
Except for these bugs, performance of Spondoolies gear improves considerably as temperature drops. On an SP30, you can expect about 200 GH/s higher hashrate for a 20°C drop in temperature.

Hi,
I have ordered some SP20 Jackson. Some were damaged during shipping resulting in having the ASIC boards bending a little. I have replaced them back correctly in the hinges, but I'm wondering if they are safe for testing. It's easy to see that the board is curved and they didn't clearly fit in the hinges.
I want to test them before doing an RMA, but I don't want to further damage the board if that could result in a malfunction.
Thank you.

I too am experiencing roughly the same hash rate. I think it is probably as good as it is going to get

I can use a 1 kW PSU (stock PSU from AntMiner S2) to power one of PCBs of SP20, and I can buy additional 750 W PSU to power second PCB, can I? Or somehow the power should be distributed equally between the PCBs?
No problem doing it.Quote
- Maximum power output – each SP20 requires 1152 W RMS continuous power. Spoondoolies-Tech recommends adding a 20% margin to handle power peaks.
No need to use equally rated power supplies for both PCBs. They are electrically independent.
I would recommend clarifying that each hash board should be powered by ONLY 1 psu, so that in the case of psu failure in a cross connected setup doesn't induce system damage etc

Updated cgminer and miner_gate_arm for SP10:
Stop mining and then copy the binaries from this archive to your /etc/bin/ directory with scp.

Toom.im is now accepting SP20s for hosting. If you need a power supply, we can supply one for $100.
How much for an SP20? I guess around $110-$120 for a 1 month contract?LOOP[5] ON

This happens on occasion. Unless the ASIC is physically damaged, it should recover if you restart minergate. Firmware 2.5.12 has this problem less frequently than 2.5.6, but they all can get it for different reasons. If it's a regular problem, you can set up a script or cron job to restart minergate once a day or something like that.15: disabled (Asic all engines fail BIST)

Restarting minergate doesn't have any effect unfortunately. The only way I've got it to come back on is to disable it in the Asics Control Panel, and then enable it. Then it comes on for a short while and then disables itself again.

now should I let the temps drop below 0c and see what happens?
I've confirmed that version 2.5.13 will usually continue to work below 0°C, whereas 2.5.12 and before will go into "thermal shutdown" mode because -1°C gets misread as 255°C by the firmware. However, there are also some intermittent noise or ASIC reliability issues at low temperatures that 2.5.13 does not fix. I suggest that people try to avoid very low temperatures for another week or two while we look into those noise issues. Once an ASIC has an issue at low temperature, it makes the whole machine stop working until you isolate and disable that ASIC. While the ASICs usually recover after you bring the temperature back up, they don't always. This headache is really not worth the extra 30 or 50 GH/s you'd get from the lower temperature. Jump to:
