Title: Review of the Spondoolies-Tech SP10 „Dawson“ Bitcoin miner (1.4 TH/s) Post by: ShadesOfMarble on April 22, 2014, 11:04:12 PM I've been selected as a reviewer by Spondoolies-Tech for the SP10 miner.
Here is a link to their official thread: https://bitcointalk.org/index.php?topic=521520.0 And the website: http://www.spondoolies-tech.com/ I received the unit today and as I was not prepared for that I will not be able to give a full review right away, so I will start with some impressions first :) (Link to full gallery: http://imgur.com/a/kASCu#0 - Pictures are from my unit) https://i.imgur.com/dfBQwdh.jpg Note the text on the fans - "Xtreme" - that's exactly what they are. Make no mistake, this unit is loud. It's louder than my hairdryer. It offers multiple performance modes which also has an effect on the loudness. "Quiet" mode is about as loud as my hairdryer :D I guess there is no doubt that Spondoolies-Tech is a legit a company, as they already have delivered regular orders. (I guess my sample unit is from April batch.) I've been running a 3 TH/s mining operation using BitFury hardware, which was very cumbersome to setup. The SP10 is incredible easy to setup - plugin power and LAN, have a look at your DHCP server or run a network scanner (I used http://www.softperfect.com/products/networkscanner/ ), navigate to that address using a webbrowser - done. The hardware by Spondoolies-Tech is not for hobby mining, that's for sure. Their hardware is a professional as it can get [which also manifests in things like the loudness ;) ] To be continued... (I will also happily answer any questions you may have.) Title: Re: Review of the Spondoolies-Tech SP10 „Dawson“ Bitcoin miner (1.4 TH/s) Post by: ShadesOfMarble on April 23, 2014, 09:40:10 AM Initial post:
The SP10 offers the following modes of operation (first three columns taken from the webinterface, last column added by me): Code: 1.00Th / ~720W / ~quiet / 1,39 GH/s/W As you can see, the slowest (or "underclocked") mode is most efficient, whereas the two fastest modes offer about 20% less performance per Watt. Update 24.04.14: Code: Mode (Web UI) | Performance | In/Out Temp | Power (Wall) The power measurements were done on a 230 V circuit. The numbers for every mode except "turbo" and "idle" fluctuated, so I included the lowest and highest reading. The "average" power draw is somewhere in between. In normal mode, the unit hits the advertised 1.4 TH/s exactly. "Turbo" mode does not give much more performance (about 3,1%), but decreases the temperature by 3°C. The lowest performance mode also gives the lowest temperature, whereas the other quiet mode gives the highest temperature (3°C more than "normal") and a 5% reduction in performance compared to the standard mode. So, as the "quiet" mode does not deserve its name (I would rather call the mode "efficient", as that is what is is - more energy-efficient than standard/turbo) - my recommendation is to either run this unit using the (slowest) 1Th-setting, which will give the best performance per Watt and also a low temperature. Otherwise, one should choose "turbo" mode over "normal" mode because you get both a lower temperature and a bit better performance at only marginal increased power consumption.

LOL.
Waiting for a more detailed review of the unit. Do you think there is anyway beside firmware to baffle the sound? Title: Re: Review of the Spondoolies-Tech SP10 „Dawson“ Bitcoin miner (1.4 TH/s) Post by: jelin1984 on April 23, 2014, 10:03:43 AM why simple put better quality fan

After reading through the comments other people, who received their units earlier, have made, I was expecting something, but my expectations were greatly exceeded ;)why simple put better quality fan Well, this is a 1U device, and power consumption is above 1 kW. Looking at the webinterface, there is a temperature reading:Temp Front / Back 28 °C / 82 °C I have not opened the unit yet (will do that, but there are already pictures of an open SP10), but I guess the thermal management is well-engineered. So I don't see any way to make this unit more quiet, at least not using air cooling. You have to dissipate the heat somehow. The problem isn't that the fans are of bad quality, but that they are spinning at (estimated) 4000-6000 rpm. Even if the fans had loud/bad bearing, air movement will always be magnitudes louder at this level. Even if Spondoolies-Tech manage to build in a better (read: more quiet) fan management, this unit will never be "quiet".

If you want to run this at home, buy a quiet rack cabinet, e.g. http://www.acoustiproducts.com/en/ucoustic_active.asp You can even get them in wood, they look like a nice piece of office furniture: http://www.acoustiproducts.com/en/ucoustic_wood.asp Title: Re: Review of the Spondoolies-Tech SP10 „Dawson“ Bitcoin miner (1.4 TH/s) Post by: bitcoiner23 on April 23, 2014, 10:33:16 AM If you ever visited a real data center, you know these fans. The dB don't matter there. And that's wat this Unit is designed for: 1.25 U rack mountable for a datacenter rack.
Thanks for your review. Makes the SP30 Group buy decision even harder :) Title: Re: Review of the Spondoolies-Tech SP10 „Dawson“ Bitcoin miner (1.4 TH/s) Post by: dogie on April 23, 2014, 10:52:05 AM I STILL HAVE A UNIT IN MY LIVING ROOM, YOU GET USED TO THE NOISE LEVELS AFTER A WHILE.

How would that look like? Currently, cool air is sucked in at the front and blown out of the case at the back by a battery of fans (see http://imgur.com/a/kASCu#2 ). So the air is moving in a "straight line", I really don't believe it does get any more efficient than that. Also, the PSU adds some noise. Having such a small form factor (it's really small considering it delivers up to 1.4 TH/s) just limits what you can do in terms of cooling.Title: Re: Review of the Spondoolies-Tech SP10 „Dawson“ Bitcoin miner (1.4 TH/s) Post by: TheRealSteve on April 23, 2014, 02:58:17 PM How would that look like?

Having such a small form factor (it's really small considering it delivers up to 1.4 TH/s) just limits what you can do in terms of cooling. The air can only move in a 'straight' (a CFD simulation would be fun to watch) line because the case is pretty much closed except at the two ends :) But in terms of what it would look like - pretty much exactly what it sounds like, replace the axial fans with a cross flow fan. Normally I'd be concerned about space, but given this shot (finally - thanks, Dogie!), I'd say the space for one is definitely there: https://farm8.staticflickr.com/7243/13540240174_de9005ae25_z.jpg . The main concern I'd have is whether the displacement (velocity and volume) made up for by less dead space is enough to make up for the loss of displacement from generally being less efficient. Note that this is just wrt noise - obviously these devices are not meant to be put in bedrooms in the first place and sacrificing silence for performance is the norm :)Title: Re: Review of the Spondoolies-Tech SP10 „Dawson“ Bitcoin miner (1.4 TH/s) Post by: gamersglory on April 23, 2014, 07:22:47 PM Bet i could find a way to quiet it down.

I would like to have this thread dedicated to my SP10 review and questions regarding this unit/review. (I'm not saying either option is better. Everyone has to do due diligence. Then, buy mining gear or buy BTC or buy nothing.) Title: Re: Review of the Spondoolies-Tech SP10 „Dawson“ Bitcoin miner (1.4 TH/s) Post by: JWU42 on April 24, 2014, 01:53:23 AM Thanks for the review -- looking forward to more.
Could we get a video of the fan noise.

Update 24.04.14: Code: Mode (Web UI) | Performance | In/Out Temp | Power (Wall) The power measurements were done on a 230 V circuit. The numbers for every mode except "turbo" and "idle" fluctuated, so I included the lowest and highest reading. The "average" power draw is somewhere in between. In normal mode, the unit hits the advertised 1.4 TH/s exactly. "Turbo" mode does not give much more performance (about 3,1%), but decreases the temperature by 3°C. The lowest performance mode also gives the lowest temperature, whereas the other quiet mode gives the highest temperature (3°C more than "normal") and a 5% reduction in performance compared to the standard mode. So, as the "quiet" mode does not deserve its name (I would rather call the mode "efficient", as that is what is is - more energy-efficient than standard/turbo) - my recommendation is to either run this unit using the (slowest) 1Th-setting, which will give the best performance per Watt and also a low temperature. Otherwise, one should choose "turbo" mode over "normal" mode because you get both a lower temperature and a bit better performance at only marginal increased power consumption. Update 26.04.14: More pictures: http://imgur.com/a/afpMF#0 what is the correct settings to get 720-900 watts at wall? fan speed 50 start volts top 0.635 start volts bottom 0.635 max voltage 0.642 max power 800 dc2dc current limit 50 please tell me the correct settings on each one of them so i can get 1ths at 720-900 watts at wall this 1250 watts at wall is killing my power bill with 6 of them running. i am still pulling 1150 at the wall and it will never change i have the max watts at 800 and it still pulls 1150 at my wall.

Update 26.04.14: More pictures: http://imgur.com/a/afpMF#0 how did you do this? i keep on getting 1150 at the wall. 1.00Th / ~720W / ~quiet is not possable. 720-900 watts is not possable. this 1150 watts makes my power bill $1,200 a month. i need to lower it to 720 - 900 watts. how do i lower it? what is the correct settings to lower the power. nothing is working.
