@Powell: Can't believe such words coming from a businessman. Just saw a spoiled child and sour grade.
@bobsag3: You are not our authorized distributor. You just got some other brand miners, not JTminer.
says a lot about the product when the one good review isnt actually for what you sell/sold

I just received another S1 today and this one was used big time. Lots of Chinese dust all over the PCB boards and fan blades. Should I contact them and have them replace it?
Also might be a sign of things running out and new model coming out.
You are lucky that your S1 works. I received heavily used and semi-dead S1 from them. All covered in dust, heavy smell of burnt electronics, a lot of dead chips - one blade shows 8 ASICs instead of 32. It hashes only at around 120 GH/s and sometimes just stops hashing with beeping sound, needs power cycle to start again. I paid 130 euros customs tax for this unit, and it would cost around 200 euros to ship it back to Bitmain and then I have to pay another 130 euros to customs for the replacement unit. Just does not worth it. So Bitmain sold me a dead unit and now just stopped responding to my messages. 1) screenshot? 2) what is your PSU - dead chips and rebooting are common signs that your PSU is a bit too weak (you need one rated 550W+ with at least 500W on the 12V rail to run properly)

I have plugged my new Antminer S1 in, the sticker on it says to use IP 192.168.1.99; I have setup my gateway mask to allow this network to be routed.
On the Antminer itself I see the ethernet light flickering so it looks alive; but red light is on, on the controller card AND my browser on my computer does not display the Antminer menu page at the sticker address
Please help!!!!!
sounds like you have not bothered to read/follow the setup guide - follow the guide and you probably will find out what the problem is Klondike, yes I have bothered and followed the part I needed to follow from Dogies setup guide - since my Ant S1 has the PCIe connectors. PSU is good, router is good, what’s next? I can’t get to the login menu. You really make it sound like you know what my problem is, so can you write something actually helpful and share this with me please? Your computer may not be on the same IP and sub net and can not communicate to the Ant. Check the troubleshoot thread sushi has step by step set up. https://bitcointalk.org/index.php?topic=344970.0^this is the sort of pre-requisite reading i meant. Your issue of 'i cant connect' is too vague. I dont know what you have tried or what you havent.

All them racks of ants make me jelly! how many days to ROI on S1 now-a-days?
About 2.5-4.5 months depending how optimistic you are. In all honesty when i got my first batch antminer in (..janruary?) I expected it to be retired in may - now it looks like it will be profitable for another 2-4 months after that. Its tough to say where difficulty is going, but i think its possible we may see a single-digit change occur in the next month, and may not go past 20% again

I think the antminers are pretty well priced. With BTC$600 the units may look like a tough break-even but with BTC$800 things look a bit different.
I personally feel like a savvy user with power at <$0.15/kwh can make a 10-20% overall profit in a fairly short timeframe compared with other investments. These will not just magically make you a fortune though, and there is risk of bitcoin going down in price, which makes them even less profitable in comparison with power costs

i take no responsibility for treating it well, and will retain all rights to use it like my own, including resale or as acceptable currency when my own should would otherwise be required.
ps: the seller MUST take full responsibility to not offer thier soul to anyone else, and MUST UNDERSTAND that once they have sold thier soul to me that they cannot invoke 'take-backs' or tell others that they still have a soul, when in fact it was already sold for a pittance of digital currency
^realised the offer is after you die. My offer is still valid, but i have a few questions: 1) how old are you? 2) there is a cat on the other side of a busy intersection. You are equipped with a bicycle, a pair of shoes, and a large red balloon (filled with normal air, so it does not float well). What do you do? 3) have you ever seen your parents having sex? (this one is important, don't ask why)

bitmaintech is a scam do not buy no costumer service 1 month to get a miner, 48 hours my ass hope you dont get a bad miner good luck getting it fixed. I thank sushi is on drugs and cant do his job
Bitmain sent us more than 1000 Antminer S1 just in the last weeks, in all the cases they were on time or before. Can you post the BTC payment transaction ID so we can check at the blockchain, order number and the tracking info to check what you are saying? Juan webmaster@bitmaintech.comFeb 25 to me BITMAIN Order Shipped Order ID: 00120140216150346811UafiO0to06D5 Date: 2014-02-16 15:03:47 Total: 2.9 BTC Payment method: Bitcoin Payment Amount (BTC): 2.9 Address: 1JzDDTP7KKGNNojtJkJ2r8ghVojo9Zc2r9 Tracking No. 1ZR239350444529176 Date 2014-02-25 18:02:51 to me Hey, I need your shipping address to pass on to the warranty team for your replacement... Can you give me name and the shipping address ASAP? ? Gotta meet Cutoff Time for Monday Process Thanks he did not ship the replacement for 1 week after this I'm confused here. You ordered on February 16th, during Chinese New Year. That was when the website clearly said that they would start shipping again on Feb 28th. Your unit in fact shipped 3 days early on the 25th, and you got it on the 26th. It appears that there was a problem with your unit, and you're calling them a scam because it took them a week to send out your RMA unit? i love how every one has come at me for getting a bad miner and having 2 weeks of living hell to get it replaced i see everyone only said they got the miner on time but did not have the rma ride i had hope you don't. to top it all off sushi said i was blackmailing him for the replacement and the refund he told me about. posting this is illegal or legal cant remember what make me a black mailer and what makes me a unhappy costumer according to sushi he recorded the last phone call trying to entrap me so i would not keep telling you what happened. ask him to post it see for your self the hell he put me through learn to add it was 2 weeks and one was because sushi did not send my miner the week before as he said he would soon as he got the tracking it took 4 days to get the first response and no refund for the diff in price drop while i waited 1 month to get my working miner i ordered as soon as it was up on the 16th nothing posted about the 28th till after i pay not a prob the fact the miner was bad not a prob the way i was treated problem threatened with black mail because i needed a warranty, problem i have not posted to this form or any other form before this bad costumer service so how bad was it to get me to make more post face book u tube you name it than i ever have in all my life very bad so bad i have lost all faith i bitcoin and am thinking of deleting my wallet with the btc in it and maybe a hammer to the miners all 700 ghs that is how bad it was, i realise i should not make big choices when i have had a long hard 2 weeks if i do this it will not be out of anger it will be thought out and made with a clear head what was wrong with your unit, if i might ask? I did an RMA on one of my miners from the first batch, where the secondary hashing board would not hash because either the TPS53355 or a related voltage-control component was not issueing 1.1V to the first segment of 8 chips. Sushi was very understanding and while it took 2-3 days to sort out the method of RMA - he shipped me a replacement board FIRST and then covered the obscene costs of sending my bad board back to china. (It cost less to send a full antminer from china->canada then it cost to send a single PCB w/o heatsink back) These guys push alot of gear out the door daily, and the failure rate thus far has been very small. The fact that this caused you to want to delete your BC and destroy your current miners gives me the impression that you are not capable of understanding the situation

Its probably in the mail already. The shipping team is fantastic, but they have to manually mark your order as shipped. By the time you get the tracking number, the package will probably be somewhere over the ocean, or just arriving at your customs

Your choice, of course, but if it works I'd say use it. You'd lose a significant amount of income by being without a unit for the 1 or 2 week turnaround, plus paying for shipping to Bitmain. You'd need to mine for many weeks to recover that, and you'd never catch up to what you could have mined by keeping it. 'chinese dust'? Why would you RMA something because it is dusty? get out the compressed air and clean it yourself in a few minutes. You can use 99% isopropyl (rubbing) alcohol and a microfiber cloth to clean the pcb if the air duster isnt enough

^if re-designing the board like that, a water block would be particularly good. putting 500GH+ on a single block with a radiator would make cooling a lot easier and reduce the noise and costs of air cooling.
|
|

I can envision having an antminer where a pair of big waterblocks measuring about 10"x10"x2" (about the size of two of the current heatsinks stacked vertically) could have 4 blades bolted to each it and would only require about the same amount of space as 2 antminers
{[]} {[]} {[]} {[]} {,} represent hashing boards [] represents waterblock |\ /| [radiator]
<-~12"->
Bitmain could probably achieve this via chinese manufactures pretty cheaply, maybe at a 5% premium considering the overall metal mass would be similar to 8 heatsinks and the rad could run with 2 fans instead of 4 fans (save $5-10 per fan).
The only issue is that the board design or orientation may need slight tweaking in order to accomodate the back-side chips near the requlator as well as allowing connections for power and ethernet still. (In theory, a single control board could probably be used, further reducing costs - but might require a slightly faster processor)

Has anyone tried a liquid-cooling solution? I was thinking it might bring down weight and noise a lot...
I would love to see bitmain do this in the S2. however, from an end-user POV there are two issues I see: 1) cost of building custom waterblocks is high, probably more then what you would save over air cooling (maybe $25/month) and by getting the extra 5-10GH (~$50), particularly in small quantities 2) you could try immersion cooling similar to asicminer, but the initial costs for that are very high (You would probably need to spend a few thousand in r&d to have one designed for 1TH or so) In bulk, the prices could be reasonable. I'm sure bitmain could have custom waterblocks made in china that weigh a little more then the current heatsinks for an extra $10 each. Add in hoses, pumps, and a radiator - you could build a 1TH antminer that takes up about the space of 3 S1 units (weighing about the same as 3 units) and requires only 2 fans on a decent radiator. The final cost might be achievable at a 5% premium over current costs. I can envision having an antminer where a pair of big waterblocks measuring about 10"x10"x2" (about the size of two of the current heatsinks stacked vertically) could have 4 blades bolted to each it and would only require about the same amount of space as 2 antminers {[]} {[]} {[]} {[]} {,} represent hashing boards [] represents waterblock |\ /| [radiator] however, the design costs for this would probably outweigh the benefits up until at least making >100 of them. There would also become the risk of liquids in your mining farm if build quality is lacking or hoses get pulled loose

What is the hashrates for those cards ?
2 280x + 2 270x: What did you put under the motherboard? I would like to know, because I am beginning on my first mining rig this week.
Nothing, its just sits on plywood with 2 screws those 270X cards could be doing 500kHash+ if you switch to the kalgoth version of cgminer 3.7.3

firstly, use paragraphs.
and no, you wont get it much further without actually swapping out components for higher amperage/voltage. To get an extra 20% speed you might use 50% more power

Seems to me regardless of what process node they use they will need to use a chip with improved power consumption in the S2. In the original U1 the chip was always under clocked. The U2+ just took the same chip added a bigger heat sink and changed the default clock rate. Since the S1 was already operating at close to the maximum clock rate they will almost certainly have to use an improved chip in the S2.
Why? Just do the reverse of what they did going from U1 -> U2 and increase the chip count. Because Bitmain still needs to turn a profit and adding more chips would increase their production costs. My understanding is that bare chip costs are quite marginal. chip costs are minimal but the initial R&D can be several million dollars

According to bitcoinwisdom.com calculator, the antminer s1's ROI in about 90 days.
Is this about correct? More? Less?
That is my estimate too however alot depends on the difficulty rate increases. Today it is expected to only go up 11%. Sometimes it jumps 20%, a few times it jumped way up even more. However based on an average of 20% increase every 11-12 days you should make about 1.3-1.4 BTC in 90 days or so. I think my math is close. plus about $200 in power costs for that timeframe
