Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip

[klondike_bar]

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.

you don't pay nothing to send it back, they will pay, and they will ship you a new one, if what you told is true, u make a photo and a screenshot.
else i don't belive you at all.
they have 10000 of customers, and no one point that(one blade shows 8 ASICs instead of 32), you are the first one.
or, you didn't buy from https://www.bitmaintech.com , and you got scamed.

My guess is that the power regulator (TPS53355) or its associated power components for the second 'segment' of the bad board died - this would result in no 1.1V signal to the chips or across the inductor, and would likely stop the communication chain to the 3rd/4th segments.

I had that happy to the first segment on one of my boards, and no chips on the entire board hashed. Bitmain took a few days to decide on what to do, and then mailed me a replacement PCB alongside my order for another antminer. I swapped the boards (the thermal paste application needed some work at the time, but seems fixed now since antminers all come with it oozing out) and mailed back my bad PCB at thier expense.

Hi, I just order one at Wednesday evenning my time. Today I received my shipment information with estimated delivery on next Tuesday  .
I can confirm fast shipment and looking forward to confirm that my Antminer is working well.

As I am preparing and reading here and around and in web installations tips. Shell I check for thermal grease as someone reffer to have a lot on the circuits? Any tip to follow before first power-on?

I have purchased good PSU - EVGA SuperNOVA NEX650G
I have my LAN using 255.255.0.0 subnet - I am a little bit confused when I see in management system of Antminer sections/menu LAN and WAN - any reason for that? My WAN is a at Gateway and I do not care about any setting.

Thank you for any tip.
 

The control board on the S1 is a customized router running OpenWRT so you use the WAN settings on the board to connect to your LAN.  Don't get stuck on the terminology

The LAN settings are essentially going to point to nothing (no hardware port) and the WiFi settings essentially bridge to the S1's WAN connection.

So basically modify the S1's WAN settings (ignoring that it's called WAN) as if you were setting up any other hardware on your network.

No pictures yet of the production unit... just broken img on the site.

The prototype bare metal box that bobsag3 posted on the other thread doesn't count... I doubt that represents how the S2 will look in the shipped production units.

Then again... the S1 wasn't exactly a looker either...

[herebittybittybitty]

ARGH! 

Does anyone know what hours Bitmaintech keeps? I accidentally sent too many bitcoins to them... and I need them back for a different order from them.

We wanna see pics of the actual production units... jeez, I even specifically mentioned this photo in my post.

yeah mate, sry, but i really think this is how it will look.

[DeezNutzz]

Newb here.  I have one S1, and thinking about getting a second. 

I am using one CX500 PSU.  should i just get another CX500 for the second unit, or go for a single higher wattage PSU and use it for both?

[Syke]

yeah mate, sry, but i really think this is how it will look.

They say it's a 4U case. Other than that, I couldn't care less how it looks. It's not going to be sitting on my coffee table. It's going to be buried in closet/hosting facility.

It could be ugly as hell, but it won't look like that... not if they are serious about saying it's a 4U rackmount case.  The prototype looks much bigger than 4U.

[klondike_bar]

yeah mate, sry, but i really think this is how it will look.

obviously its a prototype, for a few reasons:
1) a paintjob would be cheap, protective, and look good (but KNC skipped this, so maybe not)
2) it has no connectors for a rack frame yet
3) there is a fan on top? If these are stacked in a rack, that fan would be absolutely useless unless the box also has a hole in the bottom for some crazy vertical airflow concept

What about the 1000W with 1000W PSU.  An option to ship without PSU?.

The 1000W power number could come from anywhere.
1) 1000W at the wall means a draw of 880-920W
2) 1000W unit would need about 1100-1200W PSU for some overhead
3) 1000W PSU could run 900W of miners easily

Bitmain told me that I have to ship it back by myself.
I've sent them a photo / screenshot.

else i don't belive you at all.

I don't care if you believe me or not.

I'm not the first one, if you read Antiminer topics at this forum you will find people with similar problem - dead chips.

or, you didn't buy from https://www.bitmaintech.com , and you got scamed.

I bought 5 units directly from them. 3 were new and good, one was used but good and another one used and defective.

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)

1) here is the photo of my monitor screen
2) I run it with Corsair RM850. It's a pretty good PSU, I have another two of them powering two Ants S1 each without problems.

Actually I don't care much just was sort of disappointed when paid heavy customs tax for this unit only to find that it's all dusty and semi-burnt.

Have you tried running it with another PSU?  I use 2 HX850s to power 3, and i was getting a sleu X on chips when i was running two on 1 PSU.  Try getting a 550W + PSU with 2 12v rails and PCI cables that arn't split and see if some of those Xs go away.  Remember to run the unit for a while because the X has taken at least 5 min to update on me before.

Also, try SSH into and and lower the clock setting in the asic-freq file located at /etc/config

You seem to know stuff, but just in case any noobs need a tip here is how to do the freq adjustment.  Start with the lowest setting, and let it mine for about 10 min before you trust the X count.  If all work move to the next freq settings.

Download Putty, and connect SSH to your miner via its IP address

type "cd /etc/config" to get to the proper place
type "vi asic-freq" to open the file you need to change
Hit "i" to enter edit mode
using arrows keys, move to the freq you want to use, and remove the # in from of all three lines.
move to the activated freq (one without #) and add the # in front of each line
Hit the escape key to leave edit mode
type ":x" and hit enter
type exit to leave putty
log into your miner via browser and apply settings on the miner config page to change to the new freq.

I own 12 S1s and have had plenty of time to troubleshoot problems, if you need more help don't hesitate to ask me in a PM.

If i helped anyone that wants to tip, please donate to the Against Hunger Foundation (http://againsthunger.org) Their BTC addy is 16EUDLfnDuQnFt9BviqpURHPpaa5oFxN2n

They do really good work and could use the funding!

Also tried it with Delta DPS-2000BB server PSU, all the same.

Didn't try to underclock it yet.
Wanted to play with underclocking anyway, I wondering if it possible to make S1 more power efficient.
It would be great to achieve S2 power efficiency with S1 units as their price goes down and  difficulty goes up, but probably it would require undervoltage too?

Thanks!
