Title: [Review] Spondoolies SP20 + hi-res board pics + unofficial support Post by: goxed on December 20, 2014, 09:44:44 AM Disclaimer: I received a SP20 from Spondoolies tech for review. Thanks Guy! This review is being written after 3days of use. The unit has been functioning as per expectations (hash-rate = 1.4TGH/s, pulling 800Watts at wall via a 1KW 80Plus gold PSU)
(All copyrights to the following images have been released; these can be freely used by anyone for whatever purpose they deem fit) Meet the SP20 :) Full-size Keyboard for scale :D https://i.imgur.com/TqaAuAs.jpg The fan pulls cold air through this outlet over the heatsinks covering the Rockerbox ASIC chips. There are 8chips inside this device. https://i.imgur.com/oKs0eha.jpg Unboxing the SP20. I like the eco-friendly padding material. It does the job extremely well and is bio-degradable https://i.imgur.com/K2eqZgV.jpg Network Connectivity is via a standard ethernet cable. Power delivery is through 4X PCIE 6-pin power cables, the standard ones that power GPUs. https://i.imgur.com/79CNIFI.jpg https://i.imgur.com/mSb2q92.jpg Size comparison with an Antminer S3. The fan pushes hot air out through this outlet. https://i.imgur.com/P94yHbT.jpg Detailed Review It will take an average user no longer than 10 minutes after unpacking to get start mining on the SP20. The miner when first connected to the LAN, uses DHCP to acquire a local IP address. It also sends data back to spondoolies tech so that the miner's IP address can be identified by going to http://myminer.io (http://myminer.io) HTML web access to miner is via http://IPaddress of your miner Code: Username admin You can ssh to it as well Code: ssh root@<IPaddress of your miner> The fan on this miner is very Loud (Loud is an understatement, esp. when compared to the whisper from the Antminer S3. The fan noise is similar to the noise from a small vacuum cleaner; similar to the noise heard in server rooms when the fans are running at full speed). The fan is loud at all settings from 20 to 80 fan speeds. One can change the fan speed lower by ssh'ing into the miner and editing the config file. IMO fan speed of 10 or lower has been tolerable for me in a home environment. You can change the following file to lower the fan speed below 20. Code: vi /etc/mg_custom_mode FAN:10 VS0:650 VS1:650 VS2:650 VS3:650 VMAX:700 AC0:288 AC1:288 AC2:288 AC3:288 DC_AMP:170 Here's a screenshot showing the hashing speed.

Title: Re: [Review ;)] Spondoolies SP20 + unofficial support Post by: Biodom on December 20, 2014, 05:56:47 PM Great review and fan hack is great as well :).
The settings shown may work only because input air temperature is 12C. At 32C in my "mining" room, I have to go much higher in fan speed (50) at similar chips voltage, hence lower hashing (1360 Gh).

Title: Re: [Review ;)] Spondoolies SP20 + unofficial support Post by: huffdaddy5 on December 20, 2014, 09:42:54 PM I found a way to change the fan speed to whatever you want. You can edit the html to change the fan speed drop down value with chrome or firefox by right clicking on the drop down and select "Inspect Element". The html of the page will appear on the right side of your screen and you can change the attribute and text value of "40" in the dropdown list and change it to whatever value you want. After you edit the html, just click the Save button on the page. I verified in ASIC stats page and I set my fan speed to 20. FYI, my settings page shows 40 still because that is the lowest option in the dropdown list, but it is running at 20.
Here is what the html looks like.. <select name="FAN" id="fan_speed_select"> <option value="40" selected="selected">40</option> <option value="50">50</option> <option value="60">60</option> <option value="70">70</option> <option value="80">80</option> <option value="90">90</option> <option value="100">100</option> </select> for the option value that is "selected" in this case 40.. right click on the 40 for value and select "edit attribute" then change the text to 20. Right click on the text value >40<, and change that to 20. Click Save and restart your miner.

I tried it yesterday, and the temps are a bit lower than when the fan was facing the other way round. The intake side is outside my window, with the fan pulling in cold air and pushing hot air inside the house. https://i.imgur.com/z445d3M.png Title: Re: [Review ;)] Spondoolies SP20 + unofficial support Post by: raskul on December 31, 2014, 02:38:56 PM Has anyone tried reversing / inverting the fan?

Three days with the fan direction reversed and no problems yet. It also helps reduce the fan noise in the room, since the fan side is now on the window sill, instead of inside the room.

Less noice, lower temps with reversed fan. Title: Re: [Review ;)] Spondoolies SP20 + unofficial support Post by: goxed on January 03, 2015, 09:00:36 PM After reversing the fan direction, I also applied tape over the top row holes, since these top-row holes are simply passing through the outside cold air (can be verified with an IR-thermo)
