Topic: [Review] Spondoolies SP20E Jackson review by 2GOOD (Read 8016 times)
Thank you, how it works?
might be: 1 as in Max PSU Power Unit 1(or 0 in Asic stats) is 4 on the front of the miner
2 as in Max PSU Power Unit 2(or 1 in Asic stats) is 3 on the front of the miner
3 as in Max PSU Power Unit 3(or 2 in Asic stats) is 2 on the front of the miner
4 as in Max PSU Power Unit 4(or 3 in Asic stats) is 1 on the front of the miner
i don't remember exactly, but you can get a confirmation here https://bitcointalksearch.org/topic/unofficial-spondoolies-sp20-thread-872014

Thanks mavericklm,
Is this how the power units relate to each loop?
Power Unit 1 = LOOP[0]
Power Unit 2 = LOOP[1]
Power Unit 3 = LOOP[2]
Power Unit 4 = LOOP[3]

my settings:
Start Voltage 0.68 / 0.68 / 0.68 / 0.68
Max Voltage 0.74
Max Watts 255 / 245 / 255 / 245
notice the 255w and 245w
Max PSU Power Unit 1 (70W - 288W) set this one higher
Max PSU Power Unit 2 (70W - 288W) set this one lower
Max PSU Power Unit 3 (70W - 288W) set this one higher
Max PSU Power Unit 4 (70W - 288W) set this one lower
play with the 4 settings until you get your desired temps! good luck!

Excellent review. Thanks!
I'm having the issue with my SP20 where the back chips are getting much hotter than the front ones. You mentioned you can set lower start voltage for them and limit the power for unit 2 and 4 to reduce the heat. If you have done this can you show me a screenshot of your settings or maybe provide an example?

myminer.io which re-directs to spondoolies-tech.com / sails ORM finds your miners for you. how often do these miners phone home and what information is being sent ?
* Device ID* LAN address
* External (WAN) address
* Firmware version
It can be disabled in settings.
once on initial firmware, my SP20 periodically connected by itself to something called BusyBox, which from the looks of it was some automated SPT program.
It (connection or call upon) only occurred when apparently something was going wrong with the miner. I did not mind because connections like this probably help SPT to improve the software, but to see the connection was entertaining: "ET called home".
I wonder if someone else saw the BusyBox making an appearance.
I haven't seen it since 2.5.50ish, but did not look too closely because hashing is OK.

BusyBox: The Swiss Army Knife of Embedded Linux
BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.
BusyBox has been written with size-optimization and limited resources in mind. It is also extremely modular so you can easily include or exclude commands (or features) at compile time. This makes it easy to customize your embedded systems. To create a working system, just add some device nodes in /dev, a few configuration files in /etc, and a Linux kernel.

got it, so this is some kind of internal system utility that is being called upon when needed, not external.

2Good,
Can you tell me where you got the power cables from? If you made them from parts could you tell me where and what parts you bought? Thanks so much! The cables I'm using now get very warm.

Cables are 1.5 mm2 copper, bought from the local electrical store. The connectors are actually 8pin and I had to modify them to fit also from the local store.
In AWG that makes 16 or 15. I wanted to use 2 mm2 but it's too thick to fit the connector, anyway IMO 1.5 is ok,
The alloy of the wire is important too, also I soldered mine to the connectors for less resistance/heat
14awg 
where do u get your connectors? cause the cable is more than perfect but the connector is the weak point

usually ebay

i always use 14awg or above these days

I got my SP20 a little later after some problems with the Customs, not believing that I can get something for free.
You have to love bureaucracy and the pessimistic nature of those that work there.
Kudos on a great review!
Hello,
I suppose You have tested also setting more than 288W per unit. Would You please tell me if it is safe if PSU is good enough?
edit: I realized that it is impossible to set higher value then 288W

Excellent review,
I raise my glass of Christmas cheer to you,
Thanks

This is the review that made me get a couple of SP20-s. Thanks 2G
Indeed, one of the best reviews.Agreed. I was on the fence between SP20 with the Gb and the S5 and this was one of the swaying reviews that drove me to ST.
