That is a quality S3+. Each one has it's own personality. But you have to love the ones that get you the 500 GHs.

I think i had 2 out of 4 that were able to do it easy on mine. Others I was able to get to high 480 GHs.

And ofcourse my batch 1's did not match those

Like I said, it's behaving right now.

For the last several weeks it's been dropping down to 480 between 1-2 days up-time; before that it was holding 49X-50X like it is now. I don't try to run it into the ground or anything, just a little tweaking here and there.

I run mine 250 @ 0750 and it will sometimes hold 500gh/s for days, sometimes it will drop to 480 after a day, but it doesn't go much lower, it plateaus off there. I always reset it when it gets to around 482 to get the 20gh/s back. It's been good the last couple days, weather really cooled down so that might play into it.

If I set it to 262.4 @ 0750 it totally freaks out and doesn't hash worth a damn. I think some builds may just be temperamental.

ok running great at 218 about 430Gh/s if I do 262 @ 0750 it starts great in the 550 range but by 15 min mark it tanks down to 380's
same if I do 281.25 @ 0755 starts great thin drops fast to a slower than norm speed, could it be a lack of power? or is something else going on?

If your power supply can supply 70 amps or 840 watts on the 12v rail, that's great to run two S3s, even overclocked.

You need to be careful how that is worded. If the psu can supply that wattage/amperage without exceeding 90% of its rated capacity, then it's ok to run two machines. If it can do it without exceeding 80% of the psu's capacity, then it's great to run 2. The closer one gets to the rated output of a psu, the less efficient (and hotter) the psu will run.

ok using oct flash with custom ##gh/s updated in file
I can change volts and Mhz
so far turning it down to 212 MHz has given a 435 gh/s
looks solid, will try others soon
how do I find out which batch my miner is?
and what is the code for setting dif to 256? I know the bitaddress+256 thing but is that before or after the worker? #######.ant1+256 or #######+256.ant1?

I'm not aware of a easy way to do this. Best I know of is S3+ is later, S3 is earlier. And if it runs around 400-415 or so there is a better chance of being batch 1.

There might be a better way then my guessing estimate.

ok 2 old power supplys for now till the new one comes in.
as far as the solo mine i dont want to solo btc i want to solo some of the new crap coind comming out, i could do this directly from the wallet for my vid car and cpu but how to config the wallet to accept a conection from my ant miner. it would be nice to know the steps to pull off a mine on a low dif coin before it get to hard to solo mine and then switch to pool/stratum. in order to do this i need to setup wallet adn mine in the first hour's of coin start...thats when there are no good pools rdy yet.

i think this is what you are looking for its the best alt coin for sha256 and its merged mined, meaning when you mine you get both bitcoin and uno.

i got the only 256 part but bitmain told me it only mines bitcoin, but i've been mining uno on a stratum srever. last night i blew up power supply so i have an older one runing one side of the s3 can i use a dif power supply to power the other half as long as i dont plug the 2 power supplys into the same side rt?

and lastly is there a way to solo mine with the ant to a wallet download like i did with my vid miner(sgminer) or my cpu miner(minerd) or am i stuck with outside pools like stratum and p2p....can i start my own p2p and loginto that to solo mine wallet? just a point in the rt dir. would be nice.

A power supply is rated in watts or amps. One S3 can use up to or more than 400 watts or 33 amps, if overclocked. If your power supply can supply 70 amps or 840 watts on the 12v rail, that's great to run two S3s, even overclocked. You need to power each side of the miner with at least one plug, two plugs per side make it better on the wires coming from the power supply. 12v is 12v you can have a different power supply on both sides, in that case they only need to support about 18 amps or about 220 watts on the 12v rail. Finally, you can initiate a hand-off with power supplies with zero downtime. One power supply would have to support the miner on each side with one plug, while you plug the second psu in the ports on each side, after turning it on. Then remove the first psu, and populate the other two plugs with the 2nd psu's wires. I can only suggest this for hand-offs, not for mining as things have the potential for messing up.

Solo Mining:

I think your best bet is to is ckpool. Read about it at: https://bitcointalksearch.org/topic/yh-solockpoolorg-2-fee-solo-mining-usade-255-blocks-solved-763510

If you find a block, you get it all, minus 0.5%. If you don't, I think you just waste electric to make heat and noise. But, if that's what you want to do, the setup could not be easier.

just got a used s3 antminer.... was wondering if there are flashes that would allow more cstom options or allow for mining other coins than btc?

You can only mine sha256 coins with a S3, changing the software would not help.

With 20 units I can image it was a pain!

Thanks very much for allowing me to retain my sanity Grin

I had about 20 s3 and s1 with wifi and had the same problem. AdvancedIpScanner sometimes found some of them but no http connection thou. I did some googling but never found any good answer. I gave up and used laptop connected with rj-45 (one by one) if I had to change setup. Painful operation but so it goes Grin

Pinhead was right.

It does seem to keep mining on WiFi. I show 100% signal strength and has an IP address. Since I cannot ping it or use the web interface until I reconnect the ethernet cable I assumed it was not working.

It is in fact still mining and submitting shares after 30 minutes, so I assume it must be working. That is a good thing.

I would feel better if I could access the web interface over WiFi. Any ideas on this part? I just used the existing firewall settings "profile" for the wired connection on the WiFi connection rather than create a new one.

Thanks for the quick response. I usually just lurk and find my answers through other's questions. Nice to have you guys as a resource and for the community and interaction.

OK, I need someone smarter than myself please.

Trying to enable WiFi on my S3+, and ready to give up. I must be over thinking this, as I just should not be this hard.

I have the antennae installed and finally have the WiFi working with an IP address after many attempts and scouring the threads here.

I have wired on 192.168.1.120 and WiFi on 192.168.1.220. Both via a DHCP reservation from my router. I can ping both IP's and get a response. When I unplug the ethernet cable I am no longer able to ping either IP address, even after waiting a few minutes (not timed, just my perception). I have also tried to restart the Antminer, and that still is a no go.

I have read it takes a while to connect via WiFi, so am I just not waiting long enough? I figured once I got an IP address on the WiFi interface I was set.

I really would like to get WiFi working so I can move these guys out of the basement into an area of the house that is cooled by the AC.

Thanks!

With wifi they don't have a antenna so it will have to be VERY close to router. But you mention antenna is installed. Are you sure it's working properly on antenna?

Have you tried close to router to see if it will connect?

So when you're connected via both line and wifi make the settings right and save. When miner is hashing pull out rj-45 cable and wait about 10-15 min and if it doesn't beep you're still connected through wifi and good to go.IP-scanner doesn't allways find devices connected via wifi.Good luck.

With cooling season approaching, I need to increase the efficiency of my S3+s or turn them off. I've seen sporadic discussions on best firmware to upgrade to, how to undervoltage, etc., with differing results.

Is there a thread on increasing S3+ efficiency and a "proven best" method out here?

It's not hard to test yourself with a watt meter at the wall. For every frequency wait until the fans are at the normal rate, then record the wattage at the wall and the work utility number on the miner. A simple calculation will show you what frequency provides the best use of watts to hashes. Doing it yourself also will account for the difference your power supply makes.

My best option was to vent things outside directly. Problem solved for me, and still overclocked.

My numbers currently:
OC'd at 250, WU 7,021, 399 watts. So 17.6 WU per watt consumed.

I'm an electrical engineer and have a spread sheet of measurements to determine J/GH at the wall. Looking at my last bill and with my electricity cost at 0.13/kWh and the current BTC value, I'm just breaking even or making a small profit when I factored in the reduced heating cost during the winter. Simply changing the frequency won't make a significant difference. Was hoping to change freq and also undervolt but read mixed results on that also based on firmware and other issues. I had great success using the HB-lead method to keep my S1s profitable for a long time. I haven't been back here for a while and I was hoping someone had an S3 solution.

I shut down my miners and wonder about the future of BTC when more people do the same. I know if enough do, difficulty will decrease, ... Huh

If what you say is true, I'm wondering why people under-clock if performance per watt does not increase. So I had to test 200mhz with my own eyes.

To review, OC'd at 250, WU 7,021, 399 watts. So 17.6 WU per watt consumed. That's putting out an average of 505GH/s.
Underclocked at 200, WU 5680, 305 watts. That's 18.2 WU per watt consumed. Putting out about 406GH/s

So sure it's a little better, you save about one old bright hot incandescent light bulb from being on 24 hours a day, for a loss of about 100GH/s. That could make the difference in some people's power costs. Some people with lots of things plugged in or lights on might be able to save 100 watts from being used daily.

I didn't say performance per watt, or efficiency in terms of energy/hash (J/Gh) or in terms of power/hash rate (W/Gh/s) doesn't increase from underclocking (or changing the frequency). I just said it's not significant, which you confirm in your numbers above. That's why I was more interested in whether anyone had a proven technique for undervoltage, or lowering the voltage to each chip. I did this with my S1s last year and ended up reducing the J/Gh number on each by about 1/3, meaning I was getting the same hash for about 33% less energy. That is a significant efficiency improvement. On the S1s, I changed the voltage by using an HB lead pencil trace to reduce the resistance in a voltage divider circuit for each chip that led to a lower chip operating voltage. I read that you can undervolt the S3 chips much easier through a firmware switch on some of the firmware updates. But have read mixed reviews and was wondering if anyone had succeeded in making a significant efficiency jump using that technique.

In the current flash that Bitmain offers, the option to change the voltage is right on the Advanced Settings tab on the Miner Configuration page. There is no simple drop-down menu like for the frequency, but you have to enter the voltage number. Remember the default is 0.784V.

There is a thread probably that you would be interested in, I searched for it for you: https://bitcointalksearch.org/topic/undervolt-antminer-s3-771979

on all 3 of my s3s the default is 0725

cgminer --bitmain-options 115200:32:8:18:218.75:1106 --bitmain-nobeeper --api-listen --api-network --bitmain-checkn2diff --bitmain-hwerror --bitmain-voltage 0725 --version-file /usr/bin/compile_time --queue 2048 --lowmem

they did say however only a few of the batches had the chip that let you adjust the voltage. they also said the newer firmware, the 1/09 one took that option out.
