True in general. I left it open for the very few cases where it might be safe to do so, like if you wired in a dedicated 120V 20A circuit for your miners and now want to change it to be 240V (marking the white with tape at each end to stay in code, of course). Changing an existing circuit that you didn't install yourself and isn't dedicated would be a terrible idea though.

As for electrical changes in general, depends on your jurisdiction. Here a homeowner can do their own wiring; you just need to pull a permit and have the electrical inspector come out and take a look.
Not that he'd ever pass anything like what is being suggested here of course. I do all my own wiring, and other than needing an electrician once to hook up an unfused new service to the meter I've never had to call one out.

The easy answer is "Please don't do this." Period. Have an electrician to do it for you. The profession is regulated for a reason .. and if I were you .. I'd rather sleep at night.
To put it mildly, it's less firefighter effort this way.  

^^^exactly.

the sp20 right now is a way better deal than the larger miners since you get free shipping when you order over 3, also the hash rate is about the same.

Please don't do this unless you really know what you're doing. It's one thing to get a double pole breaker and run a new branch to a receptacle just for mining gear. It's entirely another to replace the receptacle on an existing circuit and converting it to 240V. That's extremely dangerous unless you know with certainty that there is nothing else attached to the line.

I know its so simple and maybe $40 in parts!

Actually all houses in north america have 240.  They  only use  1 of the 2 phases to make  it output  115v for  safety  reasons.  

Using a double  pole breaker, combining 2 will make it 240. Choose correct  wire thickness   then  change receptacle outlet in wall to match plug.  The same as they do to  power household 240v items  like electric Stove. Dryer. Ac.  Furnace. Tankless  heaters.

lucky you-ai am on 110/120V, which makes it difficult to run many miners.

my house running 223v AC

off topic of your question, but sp35 runs only on 200-240V.

hey guys, planing to buy sp35, curently 5x ant s4. i cant find any reviews for them, can anyone say few words... can i overclock the sp35? are they stable? if i overclock how much power compsubtion will they need. the miners are ok, but i will not buy more of them. how are they compared to ant s5? thanks

like this? >> http://powerprice.info/SPT/graphic.php (raskul .. see the cgminer restarts when the voltage @wall changes)

>> this is the part extracting the data .. https://github.com/wh00per/SPT-Historian

if you need help with the display part, I can post that too on Gitgub. The github package contains a pull request I've submitted long ago fixing some INC files inconsistencies in Minepeon. Be sure to remember that all the changes to the PHP scripts  (www folder) are not persistent after reboot.

I can parse the individual asic temperatures too .. but at that time I was not interested to go that deep.

Hello - Anyone by any chance has a script or alike that will monitor the SP's temperature overtime and is willing to share?

I suppose the "bestshare" (max accepted share diff * 65535) info could be adapted so that it tells you how many hits above the network or max pool difficulty you get, however "blocks found" is a pool feature IMHO since some of the blocks might be orphans and some of the pools might run with different difficulty settings .. CGminer does not offer this info through an API call because it's not something persistent after the software restarts. It might tell you how many times you solved shares above the pool difficulty as long as it's running .. I'd say that even the antminers give out informative messages on this one, which might be different from the "absolute truth" reported by the pool in your account there.

If you solomine, it can be accurate since you don't have shares, and the only difficulty you monitor is the current network difficulty you mine on. At this point accepted shares and rejected shares is the best a miner can do in an accurate manner, since every other information is dependent on the confirmations on the network or the pool settings. If you solomine an "accepted share" corresponds to a block found .. and even then, if you restart cgminer, that info is gone.  I'm speaking about cgminer restarts, because this happens way more often than a minergate restart. Fluctuations in voltage are usually one reason for which cgminer restarts automatically. If you have a noisy power supply, cgminer restarts happen all the time and you'll lose these stats anyway.


Raskul .. do a http:///monitor.php call in your browser .. It contains the CGMINER JSON reply on the SUMMARY call .. which does not contain the "Found Blocks" line .. Everything in there can be displayed easily on the GUI.

zvi can you put a stat in the GUI to show how many (if any) blocks a miner unit has found please? antminers have this FoundBlock

there is a space on the page below


on my rack units.

cgminer 4.8.0 means most probably that you set the "flag" in the advanced settings that allow extranonce version for nicehash.

I remember this one:
You can also download pre-compiled binaries for Spondoolies SP20 with cgminer 4.8 and extranonoce.subscribe patch and replace stock Spondoolies SP20 cgminer (instructions included in README file):
Spondoolies-SP20-cgminer-4.8.0.zip (MD5 checksum: 727bbea1dbee633a7f36825a06596c3a) found at https://www.nicehash.com/index.jsp?p=software#cgminer
I have 4.7.0 on mine, that is interesting. This was used by some but not all on nice/west hash during the paycoin rush.

EDIT: Some people used the proxy server for the SP units. The SP F/W does have an extranonoce flag in the settings tab now as well.

Hello,
I've got eight of the SP20 now.
They all have fw version 2.5.64,
my first 6 have cgminer 4.8.0,
but my latest two that i got from the group buy have cgminer 4.7.0.

reasons?
concerns?

(i tried searching back through the thread but i didn't find anything)

so I tried 30%, the wave is now so fast that can just barely heard it BUT the sound is just louder, another pitch of sound then the other unit at all % between 20 and 30. I'm pretty sure it's all about the fan.

I tried 24%, 26% and 28% seems to be the compromise.

I Will try to get an RMA or either bought another one.

Thanks for the help guys !

I would have thought he does .62 .62 .62 .62 .625  and watts at 130 130 130 130 .

What watts do you read for that evga 1300?
