Problem with antminer s3+ solo. My miners work fine for a pool. But when I try to run solo I get either a very, very slow hash rate and super high error rate(s), or the miners may also refuse to connect to the machine running bitcoin-qt/bitcoind and also may incorrectly report connections as being alive or dead. I have tried upgrading cgminer to the most recent version, to no avail. Often, cgminer quits after a few minutes. here is my cgminer command line (<> indicate substitutions to protect the innocent): --bitmain-options 115200:32:8:18:225:0882 -o http://192.168.0.2:8332 -O <somename>:<some password> --verbose --btc-address 1D7CFcY3gYMgNrns6ttRmomyGTLNzZ6XRA --api-listen --api-network --bitmain-checkn2diff --bitmain-hwerror --version-file /usr/bin/compile_time --queue 4096 here is my bitcoin-qt/bitcoind command line: -datadir=/home/<some_user_path>.bitcoin -rpcuser=<somename> -rpcpassword=<some password> -blocknotify=%s -alertnotify=%s The verbose flag did not seem to give any more info, I can find an open port :8332 on the bitcoind machine and netstat will report "ESTABLISHED" then "CLOSE_WAIT". Any suggestions on how to debug the rpc connection or cgminer would be greatly appreciated. I may have no hair left soon. The way you describe this, it sounds like you are running cgminer somewhere outside of your Ants. I'm pretty sure that's not going to work for you. Try editing the cgminer config inside the Ant to have the solo mining options to point it to your Bitcoin instance: cgminer -o http://<bitcoin IP>:<bitcoin port> -u <username> -p <password> --btc-address <your address> Also, CK (author of cgminer) has a public "solo mining pool" up.. if you don't mind the 0.5% fee: https://bitcointalk.org/index.php?topic=763510.0M I see, no cgminer is only running on the antminers and bitcoind is running on a xeon based desktop. I will definitely check the "solo" pool. Thanks. so: antminer-->cgminer <-- local network --> bitcoind<--desktop.

Maybe you're missing the http:// part on the -o parm? From the readme.txt in cgminer: cgminer -o http://localhost:8332 -u username -p password --btc-address 15qSxP1SQcUX3o4nhkfdbgyoWEFMomJ4rZ
Note the http:// is mandatory for solo mining.

I have been involved in a few of the threads related to this topic. Solo mining with an Antminer is essentially hopeless. The only way to get it to run is to setup your own pool and even that is a freaking hassle far beyond what is reasonable or worthwhile for the average person.
They run great on p2pool, have 8 S3's and a few S1's running for a while with 0 issues... That they do. I was speaking more of %100 stand alone run your own wallet in server mode and mine mine mine.

You should keep it between 50 and 60 C or less. My S3+ at stock speed runs between 40 and 50C in over 30C ambient temps. Over 70 C is bad for the hardware. Unless you disable it, the firmware will turn the miner off if either chain temp reaches 80 C.

80℃ That's the thermal shutdown temp. Realistically, you should have 40-50c ideally, but probably won't see any real problems in error rate until over 60c

during the summer mine hovered around 60 and didn't see any errors or problems. now that its winter they are running about 40 with the fans barely moving lol

Unless you disable it, the firmware will turn the miner off either chain temp reaches 80 C. If you stop function - Stop running when temprerature is over 80℃ - then you need to restart with PSU All depends on the frequency. Miner can work without errors over 80℃ width lower frequency. frequency 218.75 Antminer C1 , 74-77 ℃ . Noo x or - , 0 hardware errors proof http://www.perearstike.ee/avatar/C1.jpg

Thanks for the very useful replies guys, now I have a question about frequency. Looking at the datasheet for the BM1382 chip, I see a table for typical hash rate and power, where 225MHz is 0.528 W/GH, and 250MHz is 0.583 W/GH, and 275MHz jumps to 0.702 W/GH. So, what's the sense in bumping the clock up, when the ratio gets worse on power consumption?

The less you pay for electricity the less the efficiency of a miner matters. When that's the case all that matters is maximizing your hashrate.

I ordered two Antminer S3+ units for delivery to Thailand. The only shipping option was UPS. Both units were shipped last Wednesday. They both came to Thailand on Friday but only one was delivered. Apparently, one unit was left on the plane and went on quite an odyssey. UPS didn't even apologize for their screw-up. So here is the journey one of the units took. For a journey that should have been about 1,733 Km the package traveled approximately 24,146 Km (15,004 miles). I am glad I finally got it today. There was gash that cut through the box but the inner foam protected the unit. Right now it is hashing and seems to be working per specs.

the good news is that UPS probably spent $50 of time and jet fuel to transport it all those extra trips Yea. I kept mentioning to my brother how much extra fuel they are wasting taking it everywhere the plane went for the weekend. Wow, and you can be sure they were handled like this at each airport: http://www.youtube.com/watch?v=YbNq2xdvU_g

Wow. Those numbers are not right at all. The lowest I have ever gotten is .80 W/GH. Bitmain advertises .78W/GH. Below is my best number vs. advertised. Most of mine got between .86 and .89. With a high quality PSU running at less than 80% max current, the efficiency stays consistent (in my tests). Some PSU advertise on the box their efficiency percentages. I talked about doing a bigger study with various PSU's, but never got around to it.

I guess the numbers in the datasheet are for the chip by itself, whereas your numbers are for the system as a whole

I guess the numbers in the datasheet are for the chip by itself, whereas your numbers are for the system as a whole Ah. I see now. That makes sense. This link below is an old post of mine where I shared some stats. You will see that on the better PSU, the efficiency stayed the same when increasing the Mhz. But you have to consider the price difference on the PSU's. https://bitcointalk.org/index.php?topic=671189.msg9236641#msg9236641

Unless you disable it, the firmware will turn the miner off if either chain temp reaches 80 C. thats a bit on the high side for stock, mine is at 453Ghz stock as well, one board is at 41c and other is at 35c

If aircon is on temps are much lower. Anything below 50 C is quite safe. Usually in mid 40s when no aircon is on. Room heats up to 32 C with Antminer running and no aircon on.

If anyone emails info@bitmaintech.com and requests a coupon they will give them as many as they want. No reason to pay for them. Just email them with bitmaintech id and which coupon you want and qty.
