Okay serious offer here.
First these are not doubt Btmine from the specs and the timing of these pieces of crap.
That said failure rate is running 25-40% and Terahash units are hitting in February and suppliers doesnt want to get hit with these power hogs and the 1.2 TH units are hitting after the chinese new year. 2/15 and you supplier KNOWS this.
Two of my Ants 200 GH just arrived today $3000 and they are dropping again after 31st.....and they have a better rep then these Avalon clones do
I have some BTC not sure I want to part but here goes.
I will do 10 units knowing these are pieces of crap for 1.25 BTC each or 12.5 BTC Total via escrow.
I already have the units you are selling and half of them wont even last 60 days so what the point of trying to sell the ROI when it IS NOT THERE.
Please PM me if you are interested.
Thank you
ps SHIPPING to states value of package is of no conseqence.
Thanks again
Cheers,
Thanks for your offer, unfortunately I'll have to decline. This is way bellow what my supplier wants for them. Thanks again. Unfortunately your supplier doesn't have any sway on the boards... Ebay value would have been $3500 tops maybe this week but tomorrow that will drop under $2700 with the diff change. Just one here or there, not 40 - take what you can get with that size lot! I have a BTMine unit I got for $1950 (no PS) and meh it works fine, 215GH or so @ stock just draws friggin 900W from the wall. Take ANTs over that anyday (410-420W). So if you can get an ANT for 1.9 then thats what like $1600? Gotta go cheaper than that especially on these forums!

Here Full specs, and its up to 448 2) 8 boards Tower BitBurner Fury from Asic Hardware. UP TO 480 GH and much more how are you getting 480ghash from 8 bitburner fury? and much more He is not. He is getting 44-48GH average with peaks of 52GH with the latest reply. I get 46-48GH average on my boards, for 370-384GH total for an 8 board stack. Sorry but 448GH and 480GH is total BS...

ordered 1 S1s on 1/15/2014, second on 1/18/2014. both arrived today. one has 1 Xed chip. second has 2 Xed chips.
neither is reaching 180. emailed bitmain. waiting for a response.
Most of he time you get xs is when they are not getting enough power So make sure your power supplies are good Just to test try powering the main blade only, that's the one with the small circuit board where the network cable goes in Of you full os, then it's probably a power issue An x doesn't mean the chip is bad I've gotten a lot of xs on various different chips Most times the hashing is steady around 180 Even though a few chips have xs reboots don't fix it, Unplug it from power for 30 seconds and power it up again Also if you cool them too much you get xs Ideally 47-48c is perfect What this guy says. Of my 100+, I have yet to have one with even one bad chip, so 2 in a row with problems makes me think PSU PSU is good. LEPA G1200 Xed chips are on system board. Canary - I respect you greatly as a longtime leader in the group buys, but I have ten of these things, and bobsag3 has over 100 and long term we don't see this issue unless its power supply related. First off the LEPA you list has 4 rails. Do you know how the rails are split? Have you tried a multimeter to make sure the power is good? Running both ants off one a single rail off that PS would exhibit this behavior. I had a buddy with a coolermaster and he had all sorts of issues with clocks and stability and we found out that was only giving him 11.1V on the 12V rail! Generally I see either all O or X on my ANTs, most have been up >2weeks. The one I do have an occasional issue with does show random X and O spread across the chips and will drop 10GH or so but a reboot or two fixes it. I plan on swapping the power supply if I see that again...

Update: order on 1/7 just got word that package is in customs in Los Angeles.
Dang DHL is fast to States. What value you had it declared and how much tax you guys in states have to pay. In europe we have vat of 19-24% of the value, most countrys have no import tax for computer equipment. Pretty sure there is no import tax for computer equipment into the US. The story I heard was they declared a too low of value on the packages thus causing extra scrutiny. I told BTMine next time ship all US-bound devices as a group and declare a higher value as our VAT is 0% on electronics. As for it being in LA, that seems strange, I don't see any note if going through HK Customs like I did with all my old Avalons. I am somewhat afraid we just saw a status update sourced from the LA DHL office but the miners are still in HK - that would suck! Mine says: Further Detail: Special clearance requirement for goods being imported to a Free Trade or Export Processing Zone Next Step: Processing and transfer of the shipment to the relevant Zone will be completed as soon as cleared by Customs.

You guys are sure worked up about this whole thing with Jupiters -- WHY?
Perhaps KnC doesn't want to sell Jupiters for the "current" going rate.
Also why be so tied to one vendor? I've owned Avalon, BFL, KnC, ASICMiner, Bitfury, and ANTMiner.
Remember you can get ANTs shipped this week for $2K for 200GH draws about 410W while my 260GH Saturn took 340W (@wall) - really the power savings of a KnC isn't enough to warrant additional cost...
So the real question is would KnC price Jupiters reasonably - I mean within 10 days 200GH will only be worth $1500 or less...

Here are the Top #4 ASIC Companies according to the polls?
At number # 1 Kncminer - 13 (22.4%) At number # 2 Bitmain/Antminer - 8 (13.8%) At number # 3 Cointerra - 3 (5.2%) At number # 4 Black Arrow - 6 (10.3%) Just buy BTC and sit on them (why take the risk) - 28 (48.3%)
Thanks for the votes! I hope this helps any one out there thinking/praying about where to invest their hard earned cash/BTC BTC.
You are getting BITMINE.CH mixed up with BITMAIN/ANTMiner BITMINE.CH has 28nm 1TH+ preorder boxes shipping... "soon" BITMAIN/ANTMiner have 55nm 180-200GH units shipping NOW Very different companies... But I digress: ANYONE doing the math needs to seriously consider how many days from now they can get whatever order in hand. Immediacy trumps soft dates any day. Think about it this way: 1TH of ANTMINERs is $10K today. How can you compare that to pretty much all of the 28nm products where if you pay today you will not get it until SUMMER? The only people who have a chance at 28nm being good ROI is *pehaps* those who bet on the right horse and got a cheap price on a first day order. Buying 28nm today? Get in line buddy - the BACK of it! Thus why in stock miners (*cough* ANT, Avalon Gen2) do have some major pull, as they will be paid off the time a 1TH+ miner even ships in the first place.

Ninja -
Are you using ghash.io as the pool for your hosted ANTs?
I would recommend switching to ANY other pool. Heck even BTCGuild is better...

you do realize these haven't been made yet and first shipments are supposedly starting feb 24th
wow feb 24th? difficult higher again. X-3 is a preorder. If you were to buy now you will be at the back of the preorder pack so I would expect to wait a month or two at least beyond the Feb 24th date. If you want something NOW the current shipping options are: 1) Avalon Gen2 clone around 220GH ~2.4BTC (see group buy forum) 2) ANTMiner 200GH (OC) 2.4BTC https://minersource.net/

My understanding is that evaporative cooling can pose a risk to electronics, as the air might become saturated with moisture. I am in search of some expert advice on this subject.
1) Is this a feasible option? 2) How risky is it? 3) Can the risks be addressed? 4) If not, what is a better option?
I work for a company that runs a few different datacenters with cheap power in WA state. We do actually use evaporative coolers in one, pretty neat system. So let me do my best here: 1) Yes evaporative coolers are an option for datacenters but it depends on the type. The cooler you linked to would be a "Direct evaporative cooling" type which basically is just like a regular swamp cooler (see: http://en.wikipedia.org/w/index.php?title=Evaporative_cooler then the "Direct evaporative cooling" title) and is not suited for datacenter use as the temperature drop is very low and a large amount of moisture is added to the air. Eventually the air can become saturated with humidity too high for the electronics to survive and then you risk frying electronics simply due to condensation concerns... 2) Well for a quick test get a regular swamp cooler in a closet, put a computer near the air output and see how long it lasts... There is obviously a much more technical answer but even then it just depends on a lot of factors. Most swamp coolers pull in outside air and rely on air entering/leaving the space to prevent the buildup of moisture. Remember these "evaporative coolers" feel a lot colder to us humans than it actually drops the temp due to the evaporation aspect. Again if you were to just recirculate the same air over and over eventually it would just be hot muggy air, and you would get condensation and start frying stuff. Really evaporative cooling could be described as "add water to the air to make it feel cooler". Again - this only goes so far and only works so much. 3) Yes by changing the design to "Indirect evaporative cooling" (refer to the wiki link) where you use a heat exchanger this eliminates a large amount of the humidity. But even this has its limitations and thus the options used for a datacenter are generally a standard AC/evaporative combination which leads us to: 4) What datacenters use: http://www.trane.com/datacenter/pdfs/TR_EvaporativeCooling_web.pdf (problem: $$$$$) Really all the core data is written right on the wiki: DISADVANTAGES: - The air supplied by the evaporative cooler is typically 80–90% relative humidity;
- High humidity in air accelerates corrosion, particularly in the presence of dust. This can considerably shorten the life of electronic and other equipment.
- High humidity in air may cause condensation of water. This can be a problem for some situations (e.g., electrical equipment, computers, paper, books, old wood).
So how much humidity do you want? Not this much: "a problem in the facility's building-management system led to high temperature and low humidity air from the hot aisles being endlessly recirculated though a water-based evaporative cooling system that sought to cool the air down – which meant that when the air came back into the cold aisle for the servers it was so wet it condensed." Long story short: "Some servers broke entirely because they had front-facing power supplies and these shorted out. For a few minutes, Parikh says, you could stand in Facebook's data center and hear the pop and fizzle of Facebook's ultra-lean servers obeying the ultra-uncompromising laws of physics." http://www.theregister.co.uk/2013/06/08/facebook_cloud_versus_cloud/The problem is any home-grown evaporative cooler solution is going to have that exact same problem. Miner heats air > Evap cooler adds water (cools a bit) > miner heats air more > evap cooler adds more water (cools even less) > miner heats air > .... rinse repeat until you have a jungle! ... then POP/FIZZLE... Why not just leave a window open?

Wow I have the old firmware boards and get about 4-8 weeks of stability on two 4-board stacks connected to a single Pi running MinePeon with and updated cgminer 3.8.1... (1300W gold supply)
Gettin 385GH average...
I do notice the minepeon load is 0.8 and I had to play with things a bit in the beginning to get it all stable but it was definitely worth it!

Mine (2) have been hashing for a week now with no overclock, missing out on almost .1 btc because of it.
This sucks sushi. Please get it together on your customer service, especially when it comes to hosting. I know I am not the only one being affected. Please others chime in here.
+1 No offense intended, but really? A quality ISP will provide you with an SLA and make retributions for downtime. A bargain basement price cable/dsl provider obviously won't have any SLA. Sushi's hosting I am sure has many layers to it, and the risk you took by getting cheap hosting is.... well cheap hosting THIS! And some of you want to OC a hosted ANT? What happens if it locks up? I wonder what 12V power they provide, as OC success a lot of times is directly related to quality of the incoming power... (source: I own 9 ANTs and host them myself...)

in what looks like an abandoned asylum is sickening.
now that is funny. never heard that statement before. Its like someone's never been to a developing country or a place with a variety of socioeconomic conditions... I don't care where they host the rigs as long as they don't get wet or too dirty. But time for the real question: Has anyone received a unit yet - what was the delivery timeline? Any chance of PAYPAL being accepted in the near future?

My hope is to get a refund or a miner before the 31'st.
Oh wow I thought that would be an easy date to hit. What day did you order? I ordered on the 7th back when they claimed "2-days" till shipping still and I've been told its in HK and should receive a tracking number today. I expect to have a miner early next week. So I was an "early" batch and here we are 7 days later with no firm details on shipping, but at least they are making noise like it's already moving inside China. What day did you order? Kind of like this thread, no interest for quite some time and then BAM tons of orders, I wonder what is actually going on over there... (face to face deals to buy current stock out from under paid-for orders like what Yifu did?) I better get my tracking number within 24hrs or I may have to contact PayPal. ANYWAY ENOUGH ABOUT DELAYS, if you didn't want a delay buy an ANT ---------------------------------------------------- Back to important stuff. So the "new" smaller design is much better from a size perspective, but now there is NO REAR HEATSINK?!!! That will definitely lower maximum possible clocks. And now they say "Do not overclock it ,overclocking may burn the PSU , if overclocking damage the machine , We won't take responsibility for that !"Well that is fine, as the PS they included was a DUAL RAIL design which is stupid to begin with in this case but if I put a QUALITY supply in there what kind of performance can I get?

They are working so hard. I can confirm that. They are not scammer. Please be patient. You ll get ur tracking soon.
how can you confirm that?? Check his post history. He is a bitcointalk user based in Asia that was skeptical in the beginning and actually contacted btmine directly and vetted them. He was able to tour the assembly line and posted the first independent photos. Getting hardware out of China can be interesting to say the least. Normally by the time I have received my tracking numbers (Avalon DHL, ANTMiner UPS) its already spent a couple of days in transit... that's what I'm hoping for in this case! From OP: we will ship your package on time, maybe delay one day , it would go to HK first , so we can't get the track number immediately , but when we get it , we will inform you by email So they are probably handing them off en-mass to a shipper or the likes that sends them out from Hong Kong... will see! ANYWAY though, as far as "BTMine v1 Miner" now that they have "shrunk" the case shouldn't this now be "BTMine V1.1" or "BTMine V1a"?

If BTMINE are not sent devices, ordered on January 8, today, I will require refaund ..
Lead time is running 4 days. I ordered on the 7th and am listed as shipping on the 11th... so expect yours to ship after that!

The price is right but these are very inefficient units. Like the old avalons. I mean 2x 600w. Almost as bad a Asic miner blades (which I still run but at a flat fee in a data center). Antminer has them beat solidly if they lower their prices.
I thought thought Blade cubes were something like 280W for 35GH? I know my old V1 blades were around 120W for 13GH. I was hoping to get my BTMine unit here soon and see actual draw... guessing somewhere around 800-900W at the wall which would put it around 2x the power usage of an ANT but still TWICE as efficient as a cube. At my power rates that is only around $40/month to run one of these ($0.06/KWH)
|
|

Yeah, I want an antminer or 2 ... really bad, they look awesome but at 3btc ... cant justify the price vs these rigs unfortunately =/ Only benefit of antminer would be for people that pay tons in power costs I guess...
Well I paid 3.1BTC per ANT and they have already been running for 1 week and returned enough BTC to cover the spread compared to the BTMine unit that I ordered this week but still hasn't shipped. In mining it seems the good deals come & go soo quickly you really have to jump day 1 when you find something that is a deal. I think the advantage of the BTmine box is the fact it has a CASE.

Anyone has these lines in system log? what this means? I heard fans, slowing down, cgminer restarted after found usb network device again:

The Avalon design for the TP-link was always kind of "meh" as the router can't really pull enough power from its USB port to run full WiFi and Ethernet at the same time, or at least that is the way it was in Gen1 days... Recommend using Ethernet-only and DISABLING wifi on the unit if you see issues like this... Personally I really don't like using WiFi on my rigs, and if I must do it I use a ethernet-wireless bridge (gaming adapter) that I know has a proven track record. Heck you can find adapters on eBay for $10-20. If you really MUST use wireless and want it to be 100% stable 24/7/365 then what you really should do is spend $50 per bridge end and purchase a quality WISP-grade radio like a Ubiquity Nanostation. WISPs (Wireless Internet Service Providers) don't like to roll trucks when their wireless links go down and I've had pair of these radios up for ~5years outdoors with no issues! This is also nice because you can use one pair of bridges along with a switch at the remote location to attach all miners to the single link...
