I predict no one will get any compensation units regardless if they bought the PSU for it already or not. ROI on the prices we payed in 2013 are pretty much not going to happen at this point. BA won't drop the price of their miners until B1 and B2 are all shipped and at the rate they're going it's going to be months before that's finished.

Hello people, what is last known shipped order number?
I have #120x from 21 Nov 2013 and still nothing... Embarrassed

Are you looking for an X-1 or 3? Where did you buy it? Remember the order # is meaningless for shipping only the date you paid for your order is for shipping que,at least that what they tell us.

I was late December with my payment. At this point I don't know if I'm getting a refund or if they're just going to ship the miner to me anyway. Thomas from MS gave me a lengthy reply when I asked about it again. I'm tempted to say screw it and start sending letters because I'll never get my 2.3BTC back from 4 X1's with or without compensation.

10 days into August and they're still only dribbling out a few miners a week.

Oh please, I have hawked AsicMiner and Bitmaintech in the last 2 hours on this thread.  Do you honestly believe they are paying me to go after you?  Why would they?  They ship quality products from in stock, and guess what, not a single of their units have ever exploded.  Guess those high quality parts are pretty easy to come by.


Ok, I won't delete your post again and reply you instead.

AM sells only chips and they are lower quality than ours.

Would you please now go away?  You are not our customer, you have no business here.

Your further messages will be deleted.

I am a paying customer and I want to know the answers to all of DebitMe's questions. Don't disregard his inquiries just because you think he's a shill, you're the one who forced him to keep his order a secret by threatening all your customers to revoke any compensation in order to keep us quiet.

Oh, and AM chips are inferior eh? Then explain to me how chips I do not physically posses can compete with the 2 S3's I've got hashing right now? It doesn't matter how efficient it is if I don't have it.

If I were BA I would immediately start deleting everything to do with the X3 compensation PSU situation, because that is some serious fraudulent solicitation of funds stuff going on right there.

I along with others are periodically saving the forum for just this reason. It doesn't matter if they delete the posts, once it's on the internet it's out there forever.

Prolimatech PK-3 Nano Aluminium Thermal

-High Thermal Conductivity
-Low Thermal Resistance
-Long-Term Stability
-Low Dry-Out
-Non-CorrosiveElectrically
-Non-Conductive
-No "burn-in" time required



Would anyone recommend this paste?  I would like to clean and replace thermal paste.  What size would I need to do 2 AntMiner s3's


BTCBTC
DoubleDD

I would think this should be enough for one S3

Or if you have more than 2 you probably want this one

I have been looking at the explanations about how to get the S3 antminer mining bitcoins.


Bear in mind, I haven't mined at all yet, and I also am not really familiar with electronics and messing around
with power supply and such.(it doesn't come ready to mine, but I would have to get power supply stuff myself and do some kind of paper clip electrical trick etc..)

To be honest, the explanations seem fairly daunting, with room for errors being many possibilities because
of so many steps involved in getting the S3 mining bitcoins.


What do you think? Is buying an S3 Antminer a good idea for me,

or do you think I will encounter problems in one of the many steps involved, and never actually get to the point where I am ever mining bitcoins?





This is probably the easiest solution on the market right now. If you look through the last 4-5 pages you will see a lot of recommendations for power supplies. It's really easy to setup and there are plenty of write ups on how to set them up and configure them.
108  Bitcoin / Hardware / Re: ANTMINER S3 Discussion and Support Thread. on: July 29, 2014, 02:28:22 AM
Got my S3's today and they're happily hashing away. They've been up about 2.5 hours so far and I'm getting 445-450GH on one and 440-445GH on the other. I haven't had any chips blink out on me yet so things are looking good.  Cool

Matt, tell us your suitcase is going to be full of X3s on your trip back!

He only went over to help tear down the X3's from their datacenter so they can ship them finally.

Another Problem. Even when set to use DHCP it it looks like its hardcoded to use 8.8.8.8 as the DNS..

Blackarrow.. please fix to use the DHCP Supplied DNS Server.

That is Google's public DNS server.  I find it to be faster than my ISP's DNS server.  I would not worry about this.

Neither do I but if they don't give you the option to change it they should at least add OpenDNS as a backup.
111  Bitcoin / Hardware / Re: ANTMINER S3 Discussion and Support Thread. on: July 25, 2014, 11:41:11 PM
This is gonna be a long weekend waiting for my S3's. They made a stop over in Alaska so no worries about shuffling around Shenzhen at least.  Grin

Ha, I had 35-40 laptop antenna's I threw out a few months ago when I moved. Oh well, anyone who has access to an old scrap laptop could pull one out of there.



113  Bitcoin / Hardware / Re: Black Arrow 28nm 100Ghash Bitcoin ASIC from $0.49/GH/s on: July 25, 2014, 02:11:32 AM
Huh, so I just realized something everyone has been overlooking, density. If you run the numbers in an average 42u rack and assuming you don't leave any gaps, you can fit 21 SP30's. That's roughly 84TH per rack. If you look at the X3, that case appears to be a 3u which means 6u per X3. So with the added room needed for these you're only going to get about 14TH per rack. Same with the S3, you can fit 3 wide and a PSU per every 3u giving you 18.5TH per rack.

It seems to me they should be undervolting these things and packing as many into a case as they can without overheating them. The heatsink is taking up too much room.
114  Bitcoin / Hardware / Re: ANTMINER S3 Discussion and Support Thread. on: July 25, 2014, 12:02:37 AM
The pricing for Batch 4 S3s are terrible! The batch 1 price after discount was 0.694.  By the time one would receive a batch 4 S3, a batch 1 will have mined ~0.25 BTC.  Do the math people!

They were also almost a pre-order for unproven hardware, so it was a bit of a gamble and should have some benefits. Blame spoon for not being able to deliver the SP30 at spec, now there's no in stock competition in sight for the S3.

BA is on the verge of shipping their X3 which is apparently getting somewhere in the neighborhood of .81W/GH. Bobsag from Minersource posted pictures on their thread of the 1/2 unit he received getting about 1.08TH @ 850-890W.

And I am by no means advocating for them, I got burned on some X1's. Just putting the information out there.

I should also add that BA hasn't dropped the price of the X3, we're talking $5,949.15 or $2.70/GH right now.
115  Bitcoin / Hardware / Re: Black Arrow 28nm 100Ghash Bitcoin ASIC from $0.49/GH/s on: July 23, 2014, 10:18:09 PM
Take a look at the difficulty :- https://bitcoinwisdom.com/bitcoin/difficulty

Looks like someone started a farm but made the mistake of ordering power supplies from BA ! LOL

I know the network fluctuates but could this possibly be our X3s being shut down for shipment?  We will never know!

I can see them now at the BA factory.... "Bobsag is coming to help assemble the miners. Quick, everyone tear down the datacenter before he arrives!"

As to the beeping issue when the share difficulty changes, don't most P2Pools allow you to set a user defined share difficulty via the password? The one I use for scrypt mining does anyway.
117  Bitcoin / Hardware / Re: ANTMINER S3 Discussion and Support Thread. on: July 23, 2014, 03:52:49 PM
Found out why one of my units was not hashing and having X's on the chips. Paste was everywhere on the inside. Even the screws holding the heat sink on had thermal paste on them.
images removed


Messy paste wont effect anything but poor cooling, unless your units are overheating, that's not the problem
His look far better than mine did... lol.  I had paste on the chips, on the pcb, on the connectors... everywhere.

correct me if i am wrong, but if others suggest that paste is there to provide a thermal connection between a chip and a heat sink, then with heat sink sitting on the top of the chips in s3, I don't see how it could be done by anything other than having paste on the top of the chips (but not necessarily on connectors, I get that).

not sure what you are asking there...

are there other ways to have a thermal connection between chip and heat sink? sure, you can buy thermal pads. search ebay. youll see in the specs that they are massively electrically resistant. need 1000's of volts to make them conduct. Same goes for thermal paste. Its very unlikely that swimming in thermal paste (even on connectors) would cause any problem at all...

yep, but the OP said that cleaning paste improved his machine. If what you are saying is 100% correct about swimming in thermal paste not causing any problems, then why his S3 was improved by removing excess and reapplying some? I just want to understand and from what I heard here, it seems that paste should be on the top of the chip in S3.

After cleaning all the paste off the chips and surrounding PCB, the unit is working at 440 GH/s after 6 hours. All that extra paste can mess with the voltages on a chip and cause hardware issues. Thermal paste should always be on top of the chip with none running over the sides. On a full sized CPU an amount the size of a pea should be applied. On a small ASIC chip the paste should be just a tiny amount and let the heat sink spread it out. If mine is not that bad, all I can think is some dude with a Taco Bell sour cream gun filled with thermal paste is shooting this stuff on.  

what ?? your saying taco bell uses thermal paste ?? you are right the thermal past should not be gooped on the chip covering the entire chip connectors and other nearby electronic components. i always replace stock thermal paste on pretty much everything anyways: http://www.newegg.com/Product/Product.aspx?Item=N82E16835426035

Best practice to ensure you don't get too much is to put a small amount on the chip then spread it evenly with a business card, drivers license or the like. The layer of paste in most cases only needs to be a couple mils thick. It's only intended to take up any air gaps between the chip and heatsink, nothing more. Additionally, thermal paste such as Arctic Silver have silver particles in it so yes it will conduct electricity.

what is the point of thermal paste to conduct electricity? I think that you are incorrect. silver is there to conduct heat better. Because silver particles are surrounded by non-conductive filler, electricity is NOT conducted.
see:
http://www.arcticsilver.com/as5.htm

 Roll Eyes

Not Electrically Conductive:
Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)

Conductive/capacitive, whatever. My point is still valid, don't use too much paste.

Another nail in the coffin for BA. Things must be getting serious if Bob is willing to spend several thousand dollars out of his own pocket to go over to China and work for free. It doesn't instill any kind of confidence when a reseller has to also play the manufacturer role.

Meanwhile I got my tracking number for my batch 3 S3's, looks like Bitmain wins this round.

Wow it really looks like Bitmain dropped the ball on these.
ALL the S1's were rock solid and everybody got the same hash rate. Plus everyone could overclock if you so desired.

These S3's have hash rates all over the board.  Some work right some dont.

My units are running at 440 GH right out of the box with stock clock.
Guess I was lucky, but luck shouldn't have anything to do with it.

Wonder if they will fix these problems or just keep pumping out defective units ?

Bob

They did say they had an issue with the DC/DC converter. To what extent I don't know. With that said, it's better they ship what they have and deal with giving some sort of % refund (which they already have offered) than to sit on the miners and tell us "next week" like other hardware companies do. They haven't opened B4 so one can assume they intend to fix the issue before opening sales again.
