His layout is terrible as well I don't understand why he did not go with a hot/cold aisle layout  :  the Sp20 is well suited to that type of layout

with only a single row of racks/shelfs it would make no sense to change the layout...

looks like 60 or so units of SP20 and they look well used.  I assume he bough them at the much higier $600- $800 rate.

due to the vented front and enclosed case.  

 I would hate to see his power bill

   he sold me one for 409 usd shipped it out to me fast  it was  the older sp20 not the sp20e.  works fine.  684 watts at the wall 1215 gh

 0.563 watts per gh.  he also sold me at least 2 maybe 3  s-3+'s    last year all good gear.

I see 2.6.12 is now available so am downloading it to see whats new. hopefully some further abilities are added to scheduling
EDIT: 2.6.12 made my system think its an SP10 and cant start mining, the fan revvs up and down every few seconds
EDIT 2: went to change back firmware, clicked manula selection, my only options are 1.5.8 and 1.5.10. The Sp20 now seems to think its an SP10 - what do i do?
EDIT 3: used SSH, typed "echo SP2x > /model_id; echo SP20 > /model_name;"  and was able to get the device to download the 2.6.12 again, this time operational

2.6.12: seems like theres a wifi function (requires dongle, presumably in the system's USB port). no visible changes or improvements to scheduling though. For that reason im curious to know how changes to the /etc/mg_custom/mode are implemented. Is a reboot required, or just restarting the minergate process?

seems like it could be easy to create a cron task that simply copies different mg_custom_mode(day) and mg_custom_mode(night) files to the actual mg_custom_mode and then re-initiates the miner. It would allow better fan control and precision tuning the voltages and wattage limits for each schedule, rather than just the max voltages

a bit confusing...
is that custom day/night your mod or did it come with V2.6.12?

2.6.12 doesnt add anything to the scheduler, it seems to add only the ability to use a wifi dongle

my above posts about custom crontab are not part of the newest FW, and should work just fine in 2.6.1 and possibly much earlier firmwares

The wifi dongle ability has been in a few releases now... unless theyve broadened compatibility or something that is...

just tested and its works fine so far, but the the parser of the voltage input fields in the scheduler seems a bit intolerant and produces voltage values like crazy 600v if you enter "0.6"

but as long as there is no change log at all, it is the big guessing

There is no need to guess, you can go to our github.
Only difference between 2.6.10 and 2.6.12 is amount of logs from miner_gate_arm. 2.6.10 had too much logs enabled.

looks like 60 or so units of SP20 and they look well used.  I assume he bough them at the much higier $600- $800 rate.

FWIW, I purchased and already received one unit from this vendor, it's working well, and was shipped in the original packaging. Can verify it's the older SP20 vs the newer SP20E's I got directly from SPTech.

Have three more arriving on Friday - He accepted an offer I made him at a reduced price.

thanks for the advice! 

But I guess not everyone is familar with that source control systems?

thanks for this note. I have glanced past that listing multiple times now. I think I will make an offer on a couple.

I would like a firmware version where the hashrate stops slowly decreasing over time, its ridiculous!

I am interested as well.

 I have 9 sp20's that just chug a long pretty much rock steady.  I don't have this problem.  I wonder what gear GenTarkin is using sp30 or sp31?  not sp20's.

I have 4 SP20s and none of them have this problem. I generally use the latest test firmware, so I can say that this isn't a problem, at least for me, over several versions of SP20 firmware. I also can't speak for the SP30 series.

[GenTarkin]

u all must not watch the hashrate of them for the first few days, they go down a good 1-3GH / day.
I have 4 SP20's...
All of them run under 100C
I do know for damn sure if we could custom tune the frequencies these run at they would be much more effecient!
The BIST is far too agressive, at the first sign of a HW error it declocks them like mad. Its ok to have a few HW error lol!
The firmware behaviour doesnt try to get the highest / stable clock at a given voltage unfortunately it seems.

I think that most of us probably have watched the hashrate of our machines.  I constantly monitor my devices and have never, over the course of ~5 firmware upgrades and four weeks, experienced anything like you mention.

Can you post some graphs, settings and logs for us to look through?

if you use auto fan and don't unnecessary cap the power to loops, then machine will bump the highest temp to 115C at your max voltage and you will get more speed.
In addition, I find that sometimes it does go down a few GH in comparison with first hour, but then IT ALSO goes up if you wait for longer than 2-3 days, basically fluctuating in a long waves of +/-5 to 10GH or so.

I wasn't looking for that small a decrease, and I'm not sure it would show up on the graphs (maybe the 1 month, but I haven't had mine long enough). I also adjust voltage often as these are run in-home, but I've recorded the hashrate I get at a given voltage level and it always is right around there, variance does not seem to bias downward.

Does the hashrate go back up after a reboot? If so, 2-3ghs per day doesn't seem like its that big a deal if you can reboot every couple days, unless you're running thousands...

this seems to be true for me.

most of my machines are 1050 to 1250 gh.

@GenTarkin  are your machines at 1350 or higher?

All 5 of mine drop a few Gh/s over several days. For example I have one that started at 1609 leveled out over several hours to 1603 and after 3/12 days is at 1592 and will probably stay around this mark until I restart. Not enough to see on graph but if you monitor Asic stats you will see it.
