Thanks dogie for the awesome work!


We going to release together with the 1st units shipment the Plug&Mine cloud mechanism to public, allowing to easily locate the units LAN address, making the whole set-up process even faster.

You can see how it will work in the product movie (starting 2:40):

If I had free miner
I will make better review

Great review, thanks Dogie.

Quick question (not sure if it has been mentioned elsewhere): When you say it's loud, how loud are we talking? I've got 2 AntMiner S1s, and at 1 meter it measures at ~61-62dB (using Android's 'Sound Meter' application, which seems fairly reliable). Room temp is about 20C or so right now.

Not if you received it 9 hours ago and had 6 hours of testing to run ;)

Totally Jelly.

In quiet mode WITHOUT PSU fan control its 69-70 at 1m. All the noise though is the PSU, its rediculously overcooling itself as its designed to run @ 100% load up to 50C, and its in 22C. Just that temperature difference means its overcooling by 83% so once the coding is done then noise levels will come right down to ~Antminer levels (or less).

The normal and high levels with today's firmware but PSU control would be roughly that of an Avalon gen1. As of this second they're LOUD². All in good time, the team is busily coding away new things.

If its a 1.25 U server, then there should be 0.5U between two on one side, and 0U on the other. Ie 0.5U above and 0U below. This does degrade cooling performance as the bottom side is essentially a huge heatsink, and a LOT of heat is removable from there with extra airflow. That surface also gets exceedingly hot when in quiet mode so I wouldn't risk putting a material in there.

In quiet, the only noise is the PSU fan (40mm) and the subsequent vibration it generates. In normal, the fans are loud but you can't sound dampen them.

Your waterblock would have to be around 17mm thick at max, and may be cost prohibitive due to the unusually large area of the chips (2x 475 x 440mm). I'm not sure you'd want to risk cooling the PSU internally, or if its even possible. If we pretend that the PSU can't be software controlled (which it can over I2C pins), your best chance at modding it would be an extension cable from the control board out the back of the case, to a custom PCB with 24 pin ATX, 8 pin ATX, 6xPCIE 8 pins etc so it can be powered by a 'silent' ATX psu. Would defeat the purpose of 1.25U though.

Thx Dogie for very informative review.
How much you can  OC this device ?
Its generate different amount HW's errors depend of speed settings ?
Can you post some screenshot with that data ?

We'll soon address the PSU fan speed in a firmware upgrade.

Can we swap the PSU to the next bigger model if we buy it?

Sure. We're experimenting with a bigger model under various conditions to see what the gain will be, if any.
In addition, those PSU lead time is above 10 weeks, don't expect an upgrade option anytime soon.

Great news. Don't be shy and post some results when you will have them. Having an upgrade or just buy separately option would be great. If not i think people can outsource themselves the needed model if the results are good and having a spare PSU can't be wrong at all.

Edit: Thank you for the review dogie.

We will. It's a bit low priority task for us now, we're concentrating on getting the firmware to be release worthy for next week batch.
Assume that the results will be over 1.7 TH/s in a 20C ambient temperature. However, we can't back up this number for now.
Again, if we'll offer this option, it will be an after market addition.

No digital display, bottom gets hot yes (that side directly touches the lower heatsink). It wouldn't make any appreciable difference to convection (we're talking low double digits if that), while it would slightly reduce the cooling performance of the heatsinks internally. Either way though its such a small change.

Higher clock modes tend to taper out at 1.5 with current firmware, which looks more like its capped by the power supply rather than chips or temps (as giving it more voltage between turbo and normal did pretty much nothing). In quiet mode (~1.35) I'm seeing 0.7%. On the higher clock modes it was slightly higher but not appreciable.

Remember the software isn't ready so the %s mean nothing - you'll have to calculate it manually.

Good job, Dogie...for a such short period of time...Waiting for more details...

Quick question (if you will)...Are you getting PAID for this review...?

dogie, you the man, errr......you the DAWG!!

and If I had a free miner, I would STFU and look to dogie :D and then donate to dogie

Then the fight seems to be on for the 1TH/s space

Who will blink first on price
Spondoolies  1.45TH/s @ $4995 = 1TH/s @ $3,444
BITMAIN                                      1TH/s @ $3,599
Bitmine/Dragon/Clones                 1TH/s @ $3,600 (approx.)

Who can deliver on volume?
Who's miners can be overclocked enough?

Great job mate!

Dogie,

does the PSU has its own air channel?

Thanks

+1 Thanks Dogie!

Jumping in: None of the reviewers are getting paid for the review. All of them can keep the miner for themselves

Thanks...Good to know...

Sell miner = payed

but admittedly the producer of the miner has no leverage so the reviews can be a more honest.

Well that is the same thing of course, not sure why anyone would think differently?

In any case, reviews by longstanding forum members are valuable to some anyway so thanks for facilitating this.

Looking forward to hearing from normal happy customers who will be receiving their machines in 4-5 days now!

J

That's the important thing - I'm free to do what I want. I'm free to say its noisier currently on turbo than a dairy cow (https://www.youtube.com/watch?v=D2ztvgI72mE&feature=player_detailpage#t=13). My results don't require validation and I get to work with the people developing the hardware and software to improve it for everyone else.

Not linearly, but it works with the existing air channels. The PSU is way overcooled though, the air exhausted is never very warm.

https://i.imgur.com/yHRGUqN.jpg (https://i.imgur.com/Yzo81Ea.jpg)

can you post screenshot showing the chips temp?

I dont know how you monitor the temp of the chips since its not available on Minepeon screen.

Thanks

dogie, it's cat /var/log/asics
We might add an advanced tab to the UI later

Think last night's firmware broke SSH (for me anyway) so will get you a pic once its fixed. Nevermind I was just being silly.  New firmware is even better.

https://i.imgur.com/opFP1up.png (https://i.imgur.com/eGYFEYx.png).

Anything less than 113 shows 77 AFAIK.

Is it noisier than these coincraft rigs?
https://www.youtube.com/watch?v=Ygim9rmf5RQ&feature=youtu.be

Hard to say but its a different type of noise. That one appears to be air volume noise, this one is currently a squeel + vibration.

Squeal is most likely bearings.
Vibrations can be fixed with sound deadener (that resists heat) at key joints.
I've watched the video and noticed thin sheet metal touching thin sheet metal without any insulation or anything to resist vibration.

Spondoolies-Tech, I would love to offer my services of making your miner more efficient and effective in the home, office and server environments. You can send 1 or 2 or 3 units to my offices (no more than 3 at a time please) and I can go through each one and make changes to the case, fans, and power supply (just to name a few). Once done, I can ship them back to you for your inspection and implementation. Along with the new revised hardware and list of materials used, there will be a full write-up on what was done and why. And more importantly quantified data. Cost benefit analysis for each unit will also be noted. From there, you can revise your final product accordingly. All it will cost you is one-way shipping.
 
FYI, I am here in Austin, TX where Cointerra is located and I've done all I can to help them out in their final design.

lol please dont fall for this.

I like it when they do this, makes it easier to ignore them.

"(no more than 3 at a time please)"

This cracked me up  :D

Aaand we've hit >1500 in turbo. Quiet mode > 1350.
https://i.imgur.com/BfUphRA.png (https://i.imgur.com/X9TLD2X.png)

Very nice to see (1.5 Th/s) but will be challenging with Summer coming for us Northern Hemisphere folks.  Come Winter these will be doorstops I fear  :(

EDIT:  Did this include the new FW that was posted in the main thread or just cranking the fans to improve cooling?  The links in OP are of Eligius page and not the screen grab from the miner so no FW rev #

Mine is slightly newer looking at the time stamps, the software guy churns out a new (better) revision every 3 hours or so. The cooling side isn't really a problem due to the chips super high thermal thresholds, as long as you can tolerate noise then the units will be fine. The testing by ST directly is typically done @ 30C because they have so many miners in their testing room which is a room rather than a data centre :P

You might want to upgrade to latest fw version via OTA, it gives the stablest >1.5TH/s hashing rate we had so far! :)

I have, posted results about 3 posts up :p Zvisha and I have a separate email chain as to not spam you all with firmware testing.

No prob, just noticed the FW in screenshot is several versions older then what we have today (Z. is one fast guy! :) )


Edit: Our technical blog is live!
Includes ongoing updates and release notes for the new firmware versions:
http://www.spondoolies-tech.com/blogs/technical-blog

Hey Dogie,
first of all i would like to say thank you for your detailed review on this machine.

I wanted to ask your personal opinion on this miner, do you see it as a smart or profitable investment ? 

I will only ever to refer to profitability in relative terms, because there are so many unknowns in this game. https://bitcointalk.org/index.php?topic=504530.0

We're testing and adapting the fw for hot environment as well. Here is a test in hot room we've done today:
http://storage.googleapis.com/spond_public/images/fw_24_03_14.png
In fact, our testing unit was left in a close room for the night: http://eligius.st/~wizkid057/newstats/userstats.php/1PzK2WeeB9GzZwzPPJfA2h1D25Hsv2yb5e

Good job! I think you are the first company to do a stress test to their units.

and look at that difficulty jump and the next is going to be even bigger. The storm is coming ...

Thanks. Our hw guys are ex Voltaire, Mellanox

Only 6 April + August bundles left
Next: May (Early batch) + August

Question to the community:
For SP30 it's too late (we're too deep into the design) but for future miners, is LCD with Hashrate / Temperature / IP / other status desirable ?
If so, what data to display ?

I think LCD screen is pretty useless, it will just increase the cost of the manufacturing... Most people do not watch their miners work :-)

Fixed dimensions: Shipped weight of a SP10 is 14kg, dimensions of the shipping box are 660 x 550 x 130mm. External dimensions of the case are 475* x 440 x 54.7mm (+100 for cabling). They are shipped with 6-32 (diameter) 3/8" (thread) screws for 19" racking mounting.

Temp control is key when you have a more than 4 of these in a rackspace.
A simple temp LCD readout panel would only be an extra $10-$20.
The panel could light up Blue/Green when temps were in the normal range; Yellow/Orange when getting close to the limit; Red when over temp. And in the firmware you could throttle down the hashing until the unit was back to normal op. temp.
If an LCD panel was not an option, 3 simple led lights on the front face with the same color/temp arrangements would also suffice.

I have LCD temp panels on my units with a fan control knob and a freeze switch so I can control the temps with the fan and get the temps down from 50c down to 22c in about 45 seconds.

40c inlet temp and 80c out temp?
FYI: in fahrenheit that's in=100 and out=176
And that is only for it being on for 11 minutes???
Something is not adding up...or you should've released it in the Fall and people would've been able to keep their whole home heated with just a few units.

You've missed the info above the graph, it was a stress test we did in a hot room.

Yes, I did read that part. Which is why I am confused. You say it is a "stress-test" yet the miner shows an up-time of 11 minutes. Is there a screen shot of a minimum 48 hour stress test done in the same "hot room"?

Anyone who has purchased a SP10 already received?

First shipment was send yesterday, the early birds already got their tracking number.

One more reviewer (MineForeman) got his unit today.

After 5 hours of testing: https://bitcointalk.org/index.php?topic=521520.msg5938665#msg5938665

cute miner but totally unprofitable, 60% loss
(include customs fees, vat and shipping cost)

I wish they would revise their pricing but it seems there are enough folks willing to buy and take a guaranteed loss.  Supply & Demand at work...

I am pleasantly surprised to see the very active group of folks supporting the launch of the product.  Technical blog and firmware folks posting frequently -- great to see!

Updated 'other guides in the series' to new style. Added new super high res pictures to the start of the OP.

This miner runs very hot so it will be interesting to see if they stand the test of time. My GPUs don't last very long above 100c temps! :P

Dogie, might be worth mentioning, price, $/GH, warranty period, in your review?

http://s28.postimg.org/qk99kbh99/spond1.jpg

The vast majority of the chips sit between 77 and 113C, and only a few ever over 113 in some hotspots. That's not that hot, as remember these are on die temperatures. The Antminer S1 for example uses on pcb/chip edge sensors, which are going to be 30C below their on die equivalents. These chips are also specified by TMSC to operate at up to 127C!

tldr, they were designed this way for the formfactor, and there is still a lot of headroom.

I don't mention price or $/GH in reviews because after 7 days they're already out of date. I also rarely mention warranty periods as its just an arbitrary number out of your control. A company could say they have a 10 year warranty but disappear after 4, or another company could offer a 12 month warranty but run out of parts for that generation after 6. No one knows, so its not something that should be used as a key indicator in a buying decision.

Would appreciate if people could spend 2 minutes providing feedback (https://www.surveymonkey.com/s/6F58DMP) on the guides so I can improve them.

Suggestion from a software guy:

Forget LCD displays --> add a json-rpc stat api.

What I've seen which really helps from the LCD is the IP its set at. Even if you have a default shipping IP the unit can still go walkies and end up in god knows where. Its nice to be able to see where (if anywhere) its ended up.

Our P&M feature solve that without LCD. Just go to http://myminer.io

There is actually json-rpc API in the cgminer.
They are not enabled by default from outside the miner (see /etc/cgminer.conf), but you can enable them.

Then again, best thing about LCD is the IP, all the rest are just bells and whistles, and for the IP we have myminer.io for all them miners who don't want to run an IP scan.

When i go to the URL, i got redirected to : http://start.spondoolies-tech.com/

And it doesnt show any stats.

Can you elaborate?

dogie, any cooling mod so far? did you find a way to turn down the PSU fan?

btw, how do i reverse the firmware?

After upgrading the firmware to the latest (1.2.32) from 1.2.7 , my hashrate has gone down. How do i go back to 1.2.7 ?

I wish spondoolies let users to upload the firmware file instead.


Edit: this new Firmware (1.2.32) sucks . I'm running Normal mode and its only 1.29Th/s.... With the old firmware (1.2.7) its 1.37TH/s

Edit2:
After more mining time, this is the result: Both Normal and Turbo mode :1.28- 1.3TH/s ! . In Quiet Mode: 1.31TH/s - 1.34TH/s !

The noise level seems to be the same in Quiet mode (probably because PSU fan runs full speed in all mode?) . But the temp in Quite mode is higher so i assume the case fans run bit slower.

Can someone from Spondoolies explain?

I want the FW 1.2.7 back so bad right now

Increase the max PSU draw, not sure what it defaults to.

It doesn't show any stats for me, but it does find what IP my miner is living at.


Its something that has to be done in the firmware, waiting on them.

It has no effect at all. I tried 1200w and 1250w. Same result.

Btw with the prev FW 1.2.7, i left it at default which is 1200w. So i dont see this being a problem.

My hashrate is terrible at the moment 1.28THs (normal mode or Turbo mode, doesnt matter)

Also i left the miner plugged to the same outlet. This firmware just is just messed up. Also the CGminer in this firmware is newer version. Based on my experience with mining, sometimes newer version of miner actually reduce the hashrate.

Please upgrade now once, we have temporary reverted the firmware version (it will notify you about available update again, though it's enough to do it once).

I'm upgrading now..

Is it possible to let user choose FW version to use ?

I have several SP10s, so i can do comparison of both hashrate and power consumptions.

Edit: Got FW 1.2.31, same result. Normal mode + 1250w : 1.28TH/s 1.24-1.28TH/s

Compare it to another SP10 running 1.2.7, both use same CGminer version 3.12.3 : 1.39THs

So CGminer has no effect.

Hi.
Do you have 110V or 220V socket?
Please mail me at zvi@spondoolies-tech.com so I can help you.

For FCC compliance we had to add power limitation for 110V in new versions that limits your  mining to around 1.3.

I need help!. After followed instruction to revert the FW, the performance stayed the same. So i switched it to Turbo mode to see if it changes anything, now Miner_Gate and CGminer dont even run. I tried reboot, factory reset....nothing.

It keeps saying waiting for pool connection but thats not right (also after factory reset)

Can someone help?

Asic_stats shows blank as MinerGate doesnt run.


EDIT: So i upgraded it back to 1.2.32 and it still didnt mine
I checked the miner physically and noticed amber led blinking on the back of PSU. I quickly power cycle the miner and now it runs again. I'm back to 1.2.32 tho. I wont revert the FW this time because it didnt fix the performance. It seems the power limit stuck even after i reverted it back to 1.2.7

I'm not touching it until Zvi's response.

1.3 Th/s for many US folks (110V) now...  :'(

Due to Passover, please expect a slower respond time.
You can email directly zvi@

For 110V: It should be around 1.35 TH/s with 0.8 W / GH/s ratio.
Well within the 1.4 TH/s +- 10% published spec.
There are however some variants between each miner, due to different ASICs corners.
The fact that we're using 192 ASICs in each miner should decrease the variance, unlike some other vendors.

We're still tweaking the firmware.

Thanks, i lied.... i touched it again this morning..... :D

I use recorvery SD method that Zvi told me. There are 2 methods to revert: replacing uImage file, or recovery SD.

The recovery SD method worked like a charm. Performance (1.2.7) : 1.38TH/s @ 1250w at the wall.

I cant wait for the 240v wiring now...:D

Thanks Spondoolies team

PS. would it be possible to have an option to adjust fan speed manually? or use temp as target setting (performance is auto adjusted to stay on or below certain temp) ?

Glad to hear that was sorted out!

Thanks for the suggestion about the fans speed, we will look into it.
Please feel free to submit further improvements suggestions and feature requests to support@spondoolies-tech.com.

There is a chance I'm incorrect, but I believe the fan can be controlled directly by adjusting the numeric value in the file

/sys/devices/ocp.3/pwm_test_P9_31.12/duty

cat that. the formula seems to be 12000 + (%% * 200)

for max fan at 100%

echo 32000 > /sys/devices/ocp.3/pwm_test_P9_31.12/duty

for fans at 50%

echo 22000 > /sys/devices/ocp.3/pwm_test_P9_31.12/duty

personally, I would not go less than this. but if you must, feel free to plug in whatever value you want and have at it. watch your asic screen though, if you start getting too many 119C (they show up as red), then they will downclock and you will lose hashing power.

it's a tad noisy (but I can put up with that, for this...)
ramped in (after 12 hours on full power draw - my most recent purchase (SP10 batch 2)
not too shabby!

TECHNICAL BLOG
1.49 ON EARLY MAY BATCH UNIT
I created new FW version that has option to customise DC2DC current (1.3.31-experiment).
If you have COLD ambient temperature (<25C) and slow corner May batch unit:
Set
-----
DC2DC current limit to 63
AC2DC limit to 1265
start voltage to 0.68
max voltage to 0.73
fans to 80%
------
and you just might get almost ~1.5TH in miner, which is about 1.48TH in pool.

If you don't have slow corner May unit or don't know what Asic corner unit you have, set start voltage to 0.660. I didn't try it but it might give you a bit more.

Just monitor the DCt column in the ASIC stats that it is not over 90, and I don't know how stable it is, so if you leave it over night you might loose hash rate if it falls.

It's in custom FW downloads, 1.3.31-experiment, only for the brave for now.

QUIET MODE IN SP10 1.3.XX
Quiet mode setting for FW 1.3.XX:

Calibration and warm-up:

1) Goto WebUI settings tab -> "Advanced Voltage Settings"

2) Set fans:80%, start voltage:0.660, max voltage:0.740

3) Let the unit run for 30 minutes.

4) Goto "Asic Stats" page

5) Look at the column "vlt". It shows the optimal voltage found per each DC2DC by the SW in millivolts.

6) Remember the maximal (MAX) and minimal (MIN) values. Also look at the AC2DC power=XXXX[YYYY]. XXXX is current power, YYYY is the power limit.

 

Setting

1) Set the fan to 80%, start voltage to (MIN-10 millivolt) and max. voltage to MAX (note that this field is in volts, not in millivolts).

2) Now you can play with the max Voltage/start Voltage values based on the calibration values. The system will find optimal values within the range. Try steps of 10 or 20 millivolt and see the effect on the hash rate. Leave at least 30mv range between start and max. Do this on warm system (it should be warm after the 30 minute mining). Always compare the hash rate you are getting with the AC2DC power.

3) Once you choose your voltage range and you know the AC2DC power, set your fans. The goal is to have most ASICs in the ASICs page to be in the 77C range. Here is rule of thumb for ~24C rooms: 1250W=80% fans for good performance. If you set to 1000W, you can set to 50% and it should work. Just look at your ASIC page and make sure most ASICs are 77C = then you are not wasting energy on leakage. If most of them are hotter, ether decrease voltage, ether increase fans.

 

This way you can set the quiet mode you want that will match your temperature and your board.

 

P.S. We are adding option to control max PSU limit in FW 1.3.30. Default is 1250W, but it worked for us at 1265W - 1% more. You will be able to use that extra power in cold environment only, since in hot ambient the ASIC temperature will limit you. Also in first batch the DC2DC will prevent you from using so much power at 0.670 volt. But in May batch in 0.69v it will help.  !! If you set too much, your unit will shut-down and PSU led will start blinking, you will have to power cycle and change limit !!

 

P.S.S. Well, now you can also change the DC2DC max current from next version. The spec. says 60 Amper, we set upper limit at 61. I recommend not touching those. However, you can try setting them to 62 or 63 if you are in cold environment, and you have some spare power in AC2DC. Just monitor their temperature for the first hour - it's the DCt column in ASICs page. Should be under 90C (it has thermal shutdown around 120C). You will probably need it only if you purchased powerful PSU or some of your loops got broken, so you want to pull more from other loops.

Anyway to get the older version?  I was hoping to see around 1.4 TH.

I just got mine and slightly disappointed at the 1.32 TH/s in Turbo mode. (around 1.29 TH in Normal).  BTC Guild sees the hashrate slightly lower, of course.

I'm still pretty happy with the units, though.  They are easy to set up (though they started mining for Spondoolies as soon I plugged them in).  They are LOUD, even in normal mode!  I put it on turbo so I can get the extra speed.  26 C ambient temp.  They are in the basement - cooler and don't have to deal with the noise unless it's laundry day, lol.

So, any progress on getting the fans quieter (especially the PSU fan)?

EDIT: got new firmware - 1.3.49 - slightly faster.  Between 1.33 and 1.36 TH now.  Still LOUD!

how loud is LOUD?

are we talking the volume of an S2? 4-6 S1 units? or is this vaccuum-cleaner loud?

70+ dB on medium clock.
Much louder on High.

Louder. You'd probably need 40 S2s to match the noise pressure of a single SP10.

Perfect analogy.
It is insanely loud.  Just like the data centers.

christ. Im planning on installing it in its own location where noise isnt an issue, but if the answer had been less of a resounding LOUD I may have been able to dd it to my current collection of 16 S1 and a S2 unit (which are approaching the limits of noise i can handle)

Could someone post a video/audio of SP10 running so that we could hear the noise level please.

thank you

I specifically haven't because its 1) impossible to capture 2) impossible to comprehend with a video. Use a decibelometer to comapre other sounds you know

my miner stopped hashing today

ASIC STATS is empty

DCR says

DC2DC DCR inductor flag loop 0 (0xD0) = -1
i2c write 0x71 = 0x2 error2
i2c write 0x72 = 0x0 error2

Have you tried every form of restart?

hey it works again,
I reduced dc2dc to 57 and power to 1170

Thats strange, what clock speed were you running?

Anybody know if they will discount the price on total order of 4 SP10 units?

Thanks

Unlikely on SP10s any more, you can email them though.

Dogie, is 1250 GH/s reported on BTCGuild (1320 GH/s avg on the miners) @ 25C normal for us 120v users?  One of them is only hovering around 1305 (1215 on BTCGuild).

I'm kinda disappointed at these numbers.  These are expensive units and makes a lot of noise.  Was willing to put up with it if I could get 1.4 TH.  I didn't know they had to limit it.  Should have advertised as 1.3 TH to 1.4 TH.  Can't help but feel a bit cheated/baited.

Contact them asap. They will make you whole I am sure either help you get the rate you should get or compensate you. They noted that in their thread if I am not mistaken. https://bitcointalk.org/index.php?topic=521520.0

Ignore btcguild, pool hash rates are always variable. It depends what clock rate you're in, if you haven't looked in detail then you've still got the 120V FCC cap on. You need to remove that to remove the cap of power consumption which will allow your unit to hit the higher clock modes.

Correct

The numbers shown in miner are usually 1-3% higher then the pool. That is because of the HW errors and discarded shares.
HW errors more common when miner starts (first 30 minutes) and can be up to 3%, but after a while usually around 1%. Discarded shares usually around 0.5%.

How do you remove the cap?

As for contacting Spondoolies, they worked out a form of compensation.  Very good communication and customer service!

I'm not quite sure as it detects your mains voltage and will show it then - I'm 240V so can't see it.

Well, I'm on 120v, that's why I have the cap.  I thought you meant I could remove the limitation while still on a 120v circuit.  I thought I read someone was able to do that with an older firmware or hardware.

I don't have a 240v mains I can easily use.  Even if I wanted to it may not work since it's 60 Hz.  My guess is the PSU expects 120v 60 Hz or 240v 50Hz.

You can remove the cap while on 120V as its just software based. I have no idea what it looks like though.

Please let us know if you find out how.  I ssh'd into the box and looked at the files but couldn't find anything.  If it's not in a text config file then it's over my head.

Oh it would be on the usual web interface, if its not there then its probably been hidden. The problem is the firmware is being developed at a rapid pace so things change and move faster than I can track them.

I can add option, but
1) It is not FCC compliant to pull that much.
2) I didn't do enough tests on 110V to make sure it will not harm the PSU/cables/socket. In general 110V is something I prefer not to mess with because of the heat it can create in power cables.

"Things a BFL engineer will never say for 100$ Alex."

Please do testing and give us the hash rate for those who are on 110v on future products.  Not everyone is on a 240v standard. :(

BTW, when will a home edition of the SP30 come out?  I read somewhere it will be a single PSU/half the hash rate of the full SP30.

Thanks.

I agree with dogie on this. However, I have taken a video of my SP10 along with an S2, an S1, and a Jupiter. The only sound you hear is the SP10 basically.

Here are the videos (aka "how to silence your SP10"):

UCoustic rack cabinet part 2 (https://www.youtube.com/watch?v=xefxokQFeB4)

There was a group buy of an SP-15, but AFAIK it was cancelled because nobody was interested.

Does anyone know if the hashrate of the SP30 is less than the advertised hashrate on 110v like the SP10?  If so, by how much?

I get 1.33 th/s on 110v.  I use the medium settings. 
The miner runs great on 110v, very stable and cool.

It will be less, but its hard to know by how himuch. I would guess between 7% and 20%, hopefully closer to 7% like sp10

What is specifically being metered due to the regulations on 110V? I'm assuming its a current, but a current where?

The FCC requires 1200W (I think) limitation at the wall for 110V. There is no such limitation for 220V, and manufacturer's limits (unlike FCC) not needed for compliance. The PSU has it's thermal and OC shutdown. In SP10 we pull 1350W in 220V and ~1200W in 110V. I know that in 110V SP10 can pull more because I tested it, but all our FW versions have to be FCC compliant. But then it is open source, so users can compile miner_gate_arm with whatever they want as long as they understand it will void their warranty. We plan to stay open-source for SP30 too.

Zvisha,

There are plenty of devices that draw > 1200W at the wall on 110V.  Teapots and heaters to name a few.  I suspect the difference is that these items aren't running 24/7/365.

1320W at the wall should be fine for any 110V home with a standard (15A * 110V * 15A * .8 (safety margin) = 1320W

More and more newer homes are actually coming with 20A circuits...

I was also wondering about that. I will talk to our HW guys.

not many though.

IMO the SP10 and SP30 units are built more with datacenter than spare bedroom in mind. They are loud and create a lot of heat, in fact the 1200W draw can be more than what the majority of PC power cables are rated for (10A).  If you are able to operate these at home, it may be worth the work required to either install a new 240V circuit for your equipment or to even simply swap an existing 120V circuit's (with only one dedicated outlet) breaker and outlet for a 240V one. Wiring can remain the same in most cases.

208/240V is more efficient and puts a lot less strain on the power supply - the sondoolies machine is a long-term investment/installation.

Any source for that?  I have always seen efficiency gains as very small as well.

No ASIC is a long-term investment by most traditional investing standards.

I have an SP30 order and believe it will be almost worthless by Xmas.  :'(

Designed use is not the same as what consumers choose to use products for.


Waste heat generated components = I²R

Ok, I added an option to override the limitation (after long discussion) in next FW, 1.4.2. Make sure you use cables matching your amperage (I think it can go up to 14A if you have around 110V). Just create a file called /etc/mg_ignore_110_fcc in the miner and it will ignore the limitation. BTW, the PSU supports up to 14.5 Amper.

I brought the SP10 to the DC and it is the loudest unit there. (I'm running turbo fans.)

These power supplies are beasts.  They seem to be able to do so much.  I am still surprised at how well they work on 110v.  The auto sensing of what your line is able to send is great.

I have to ask... maybe someone in the US may know... what does a plug for a 220v in the USA look like?  And where can I buy the associated computer cable?

Since we're in the US, 220v is still probably at 60 Hz.  Will the PSU be able to deal with 220v at 60 Hz, since normally 220v is for countries at 50 Hz?

It is fine. Depending on the wiring you will either be at 208v or 240v. My 240 line is reported as 245-250 in the SP10 interface. For 240v you use a breaker that bridges 2 120v lines for 240v. Nema LP6 is the plug that most PDU's use, that is the type of outlet you will want installed.

Thanks for the info.  I couldn't find NEMA LP6 on Google.  Do you mean NEMA L6-20 or L6-30?

Also, where do I find power cables that has the NEMA L6 end and a standard PC end that goes into the PSU?

I have looked at these and the amp rating is 16AMP. 
How many of the SP10s have you been able to safely run on one of these?

At 16A don't use more than 2.

I'm finding it very involved to install a 240v outlet in my garage.  It might involve digging up my backyard to put in new larger diameter conduit for 8 gauge wires and a sub panel.

I may not have the path to go from SP10 to SP30.

Hey. Thanks for the guides, great work.

Wondering if it is possible to remotely access SP-10 dashboard easily? If not, do you know of a solution to set this up for SP-10 and other miners that is secure? Thank you.

The generic solution is a $150 windows laptop with teamviewer, or a Pi with an external facing address. I'd go with the laptop anyway.

What about oven on beaglebone?
Free for sure ;)
And ovpn on my tablet also so everywhere I go I am able to connect remotely to my home home no matter of ip's
And a ovpn server in between is a must. I guess a cheapest VPS shall do it fine
Besides PC with running team viewer requires power ;)

Dogie where have you been able to pick up longer 14 awg cables for the higher draw miners?
I am not liking 16 awg with the SP10 even though it is fine.  I can only find 3 foot ones on amazon.

I'm pretty sure the cable will be rated to way above the fuse rating, or it will be breaking some safety standard. Ie even those in the UK which are a 6A fuse, that's still 1440W. The 13A ones are hard to find and are ridiculously thick. Is yours getting hot?

No it gets warm but not hot.
With the SP30 on the way and getting a rack to put my miners in I want to be a bit more proactive about power cables on some of the beasts coming out.

SP30s have 2 PSUs each at about the same power as the SP10 so no different. Most power cables are rated up to 60C as well, which is about the point which they're too hot to touch. This isn't even the failure, its just their rating.

Quite true.

Does factory reset also delete the history (graphs, etc)?

It reset's it like it was from factory... so your stats yes they should be gone.

I have not tested this as I have not had to, but I cant imagine stats being kept through factory reset.

I have Problems whit one of my SP10.

The yellow light on the power Supply is on. An Miner dont work.

I test an other power Supply but same Problem.

What can i do?

If the same problem is showing with a replacement power supply, presumably it's not a PSU ... maybe try a SD card recovery:

i got 2 sp10 that has been running smooth. but one wont start now after i changed isp connection at my house... >:( ???

got this screen.

https://i.imgur.com/iK4pIiH.png


i got 3 pools, all correct spelled as i copied from another sp10 that runs fine.

anyone got any idea?

thanks

Could anyone tell me where I can find a cheap replacement power supply.. I found an emerson one what was 1200w is that too powerful for the SP10 or is it ok to use?

As long as it's compatible - pinout, signals, physical size etc it should be fine. The 1200W rating is the maximum power it'll output, not a fixed requirement that will blow up your miner with too much juice.

Yup. If you're in doubt about compatibility past the gold finger pinout you can set the miner to use a 'generic PSU' so it won't try and talk to it.

Thanks for the advice!!

hay Dogie i know this is late but i just got 2 of these miners for low $ and i tried to set it up and it has an ip of 192.168.7.x and subnet of 255.255.0.0 and my internet has 10.0.0.x ip's and subnet of 255.255.255.224 and i changed it in the settings and now i cant find it on my router or when i try to connect i cant find it is there any way to fix it? or am i just RIP

Hiddencow its do able I have two connected to my ISP modem, if you connected them a Comcast modem you may not be able to just plug and play. If they are plugged in to the modem, SP10 is powered on then type its IP address in your browser 192.168.7.xxx should connect you, if it asks for the username//password your done if not than you'll have to do what I did. First have another router connect everything up to it, access the router 192.168.1.1 change its IP address to 192.168.7.1 , once complete the SP10's should be accessible by typing their IP address in your browser 192.168.7.xxx, once you access the Dawson manager go into setting and change the network setup to DHCP. This will allow the IP address to auto address on your main network ie 10.0.0.x

Hope this helps a little

I know this thread is probably long dead... but hoping someone here has access to the latest firmware download for the SP10.

Bricked mine, managed to restore it with recovery and boot images, but its firmware is reset all the way back to 1.3 and there are stability issues with keeping cgminer running.  Hoping someone has the 1.5 fw img somewhere it can be shared.

I gave you a merit for a proper attempt to use an old thread.

Good luck.
