Overnight run so far so good... ~450watts for ~500gh/s I think the massive HW spike is from internet outtage, it was at 40HW very early in the morning. Who knows. Either way it's minimal compared to 22,000 shares at 256 diff ( ~5mil shares )

Wait what kind of house you got? I got 3 ZeusMiner Hurricane X3 and 14 ZeusMiner Blizzards and 6 gridseed mini's -75setup in two separate rooms. Each room has its own circuit. Total 70-75 Mh/s...about 2200 watts. As long as you stay below 1600 watts per circuit you will be right...But does anybody know the max power that can come out of a house in the USA?
I want to throw in 4 Antminer S3's into the mix...
My electric bill is about $100 extra a month with all the stuff.
It depends on the house. Older homes will have less power, 100 amps or less. Newer homes can have a lot more. I'd be very careful if you live in an older home. The wiring using back in the good old days (especially in the 60s and 70s when there was a copper shortage) may be a little sketchy. BTW, it's not uncommon in the US where multiple bedrooms share a single circuit, so don't assume each room has a dedicated circuit. Your right, my house is new..I checked the circuit box and each room upstairs has its own dedicated circuit. There is like 4 bedrooms, a media room, computer room and a game room. Crazy I know. Perfect Mining house! Master bedroom is downstairs, quiet away from it all. After I turned off all my GPU mining crap, I don't have a heat problem anymore. Don't need fans or anything now... I am thinking of getting some Solar panels installed to offset the mining power cost....just waiting for the right price...

I'm just looking at this thread and bitmain site. And what i can see, quality went down the drain.i mean, quality in regards of delivery on time, process of any refunds, simple information to community.
Now it seems bitmain asking for btc in advance which is basically preorder. With s1 there was no issues related to delivery of miners. Now im reading people waiting to get their s3 mining week or more! I was hesitating to order B1,B2,B3 and it seems i didnt lost a lot. as all batches was delayed and now batch 4 and 5 is simple proeorder with no warranty that will be delivered in time frame given.
I dont know whats the issue is but even labeling boxes as miner means issues for end user. I am fan of bitmain but at this stage whats the point of ordering when their are not in stock?
Price is nice but again waiting time for B5 will kill any profit if any. We looking at least 14 days to receive any miner. What if customs will delay the process? Whats safe quantity to order? I was thinking to order 10. Any ideas how this will look for customs?
no miner is for sale at a better price and faster delivery. have they slipped from the s-1 yeah just a bit. down the drain no. down the drain would be what knc did from the early jupiter last nov to this years neptune. Based on all that i can see and read. these s-3's are better then the s-2's but not quite as good as the s-1's. By that I mean all aspects of the miner. I order 4 so far I have 2 hashing 2 on the way. when they come I will order 2 more. after those 2 come I will assess my next move. right now the mining game is very tough. Maybe i was to harhs to say down the drain. But i compering s1 to s3 situation. And thought maybe they will do same what they done with s1. I bought abut 20+ s1 with sushi and bitmain and never had any issues. I still think mining is something which will make few BTC before is not profitable anymore but for small people like me is getting more difficult and will not be easier. 10 units will make roughly 3 BTC a month. yeah I am in your boat. always less then 5-8k worth of gear. not tiny maybe a little bigger then small. but these days to be middle sized means 20th. I can't provide 20th in terms of the power needed. that would be 42-44 s-3s that comes to about 15 k-watts. I can do 4k to 6k in the winter. I can do 2k in the summer. right now I am running 14 gridseed blades in my home around 1250 watts. 2 s-3's in my friends office. 1 dragon miner in china 32mh in the zencloud a few icefury usb sticks in bitsolo.net-----------hey you never know 2 more s-3's in batch 4 when these com to my home i will be close to 1950 watts and that is about all I can do in house. Wait what kind of house you got? I got 3 ZeusMiner Hurricane X3 and 14 ZeusMiner Blizzards and 6 gridseed mini's -75setup in two separate rooms. Each room has its own circuit. Total 70-75 Mh/s...about 2200 watts. As long as you stay below 1600 watts per circuit you will be right...But does anybody know the max power that can come out of a house in the USA? I want to throw in 4 Antminer S3's into the mix... My electric bill is about $100 extra a month with all the stuff. $100 extra for 2200watts? You are a lucky guy man. The max power that can come out of a house in the USA will rely on you checking your breaker box to see what type of amps are in what rooms it will show you what the circuit is running example is Living Room with a 20A breaker on a 115/120 circuit would be 20A x 115v = 2300 max watts in ALL living room outlets. The problem with houses is if the circuits are split individually or spread around the house. example, your living room may have split outlets with the hallway and even a bathroom Thanks bro, I think I was using way more power with all the gpu's I had running last year....I think I was running about 1500 watts in one room with no issues last year.... I am done with Scrypt Asics, unless they come out with some good cheap 28-20 nm stuff one day...will ride the sha 256 asics train for a bit. I think bitmain is the best to do this with...It's still cheaper to buy a S3 than to buy cloud hash... Plus bitcoin and litecoin diffs have been going kinda sideways lately, so ROI is very possible...

I received an email from Bitmain support to say that refunds will be processed on Sunday, I initially sent an email to request to convert my refund into coupons as I wanted to buy more units from batch 4, I then traded with another customer whilst waiting to hear back, but then after my trade I received an email from Bitmain to say it was not too late to convert my refund and they would issue me with the coupons on Sunday, however by that time I no longer needed to convert the refund to coupons, so I sent an email back to say can I keep the refund and asked when I would receive it, to which Bitmain replied yes and it would be processed on Sunday. ....hope that made sense :-)
Now imagine that many BitMainTech customers do this... no wonder they get a bit behind and mixed up!

I put a six gauge wire on a 70 amp circuit breaker, from my main 200 amp fuse box to a spare room, how many s3's will I be able to run on that circuit, air conditioner is on a separate 20 amp breaker.
thanks in advance

Overnight run so far so good... ~450watts for ~500gh/s I think the massive HW spike is from internet outtage, it was at 40HW very early in the morning. Who knows. Either way it's minimal compared to 22,000 shares at 256 diff ( ~5mil shares ) Do you have any special cooling?

Was Batch 4 always Aug 7th for ship date? I could have sworn bitmaintech.com showed Aug 5th yesterday. Can anyone confirm the shipment date of batch 4?

I was able to get the discarded amount lowered as well as the load. I changed the queue to 0 from 4096 and added --scan-time 1 --expiry 1 to the cgminer file. ***IF YOU ARE NOT SURE WHAT THIS MEANS DO NOT TRY AS YOU WILL BRICK YOUR UNIT***
Thanks for this post ! Going to try this on one of my units and see how it works out. This was default on the new firmware: PARAMS="$AOPTIONS $POOL1 $POOL2 $POOL3 $_pb $_ow $_bec --api-listen --api-network --bitmain-checkn2diff --bitmain-hwerror --queue 4096" I tried it on one by adding the --scan-time 1 --expiry 1 flags, but didn't see any difference in discards or load. Maybe some of you will have better luck. Did you change the Queue to 0? that I did not do - misread what you wrote. YES!! Just changed it and am seeing really good numbers. Discards are negligible now - 20 accepts and 3 discards. Load dropped from high 2s to under 2. AWESOME!!!!! You rock! Since I've never SSH one of these, I don't want to risk bricking it. If this fix turns out to be solid though, I hope Bitmain will include it in the next firmware release. Or maybe I'll learn to SSH. On a side note. Does anyone know if you can get a better GHS/watt ratio by under-clocking the S1? I'll tell you how to do it, but not going to go into every detail (how to SSH, sed, etc). Not responsible for you f'ing your stuff up. 1. SSH into the miner 2. cd /etc/init.d 3. cp cgminer cgminer.bak (in case you really muck it up, cgminer.bak will be your backup) 4. Enter this in the terminal: sed -i 's/--queue 4096"/--queue 0 --scan-time 1 --expiry 1"/g' cgminer 5. press enter 6. go to the web interface of the miner - Status > Miner Configuration > Save & Apply - this will restart cgminer with the new settings 7. go tip Duce for figuring this out for us Duce, where's your tip jar? I owe you. This is what you're changing: Original --> PARAMS="$AOPTIONS $POOL1 $POOL2 $POOL3 $_pb $_ow $_bec --api-listen --api-network --bitmain-checkn2diff --bitmain-hwerror --queue 4096" New & Improved --> PARAMS="$AOPTIONS $POOL1 $POOL2 $POOL3 $_pb $_ow $_bec --api-listen --api-network --bitmain-checkn2diff --bitmain-hwerror --queue 0 --scan-time 1 --expiry 1" //S1 undervolt guide - https://bitcointalk.org/index.php?topic=526060.msg5838713#msg5838713 I'm attempting this mod, but when I enter sed -i 's/--queue 4096"/--queue 0 --scan-time 1 --expiry 1"/g' cgminer into putty, I get "no such file or directory". Does anyone know what I am doing wrong, I'm afraid to go much further.

Skipped from S1 to S3. Anyone wanna donate a coupon to jimmyl?
Based on free electricity, would it be better/cheaper to run S1 than S3?

Received my batch 1 miners yesterday. Realistic guesses please: how likely is it that these devices will actually ROI at some point and how long would it take to make at least some profit with them starting from today?

Do you have any other ROIed hardware you're adding these to?

Observations re S3 (vs S1)
S3 is quite a different beast. S1 was like a soldier. You give it an order to march at higher speed-and it does or "dies" trying-gives you XX. One of my S3-I give it more juice (225 vs 218.75)-it goes up to 455, then back to the same 420 GH (while keeping all 0000). Now trying 212.5, but it can do 430GH max on this-we will see. There must be a controller (probably R47) that limits the performance no matter of what mhz you give it. Cooling the case with an additional airflow from two fans directed at opposite sides did not help at all-I tried it. However, i think that experimenting with heat sinks on R47 is a worthwhile endeavor.

If ROI is your only goal at this point leave everything you mine in BTC. So if you mine let's say your first 1 Bitcoin and its worth $600 and you leave it alone and Bitcoin goes up to $800 per Bitcoin you have just increased your payback for the same amount of time by $200. But if you mine for a week and move it all out to USD then you have a return at that days Bitcoin rate. So if you think Bitcoin will rise as I do, leave it all in BTC until you see that your conversion to USD is the same as what you paid in dollars assuming you paid in dollars. Also you will have to factor in electricity. Right now with Bitcoin dropping in price its hard to feel any of these units at the prices we are seeing will ROI.

So any guesses as to why the huge flood of S3s on the market had little effect on network hashrate?

ive been having problems with my s'3s i can run one per psu fine with an 850 watt psu when i plug the second one it turns them both off and i need to disconnect the psu for a few minutes and then power it back on i just went out and got a 1200watt psu and the same thing happened does it matter which pci-e ports i plug into? should i power them on and different intervals? i had all of them on before mining and that was fine but as they start to mine they cause the psu to stop please help me cheers
