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

[pak13]

   Price for antminers has reduced
   S4 is $1200 per unit
   S3+ is $199 per unit
   C1 including cooling kit is $375 per unit and $325 excluding cooling kit

Shipping for 4 S3's to the US is nearly $200. There has to be a way to get better shipping rates.

For air freight, 2 days typical is comparable to all the other suppliers. By boat (6 to 8 weeks) you can get it cheaper.

there is no oficial bm1384 yet
bm1382 is on 28nm
next chip, maybe called bm1384 should be lower
22nm? 14nm?

BM1382 isn't a very efficient 28nm chip. If they do come out with a new chip so quickly, it'll probably just be a more optimized 28nm version. Tick Tock.

It may be overclocked like the S1's were, leaving some headroom to lower it in a later model to compete with others.

Is the L1 available? Or was this only 'pre-order'?

Any news on the L1?

what about this??? http://issuu.com/ybitcoin/docs/ybitcoin-volume1__issue4/7?e=0/9799106

s3+ upgrade path, to s5 with BM1384 chip

800gh at 0.5w/gh

Should be interesting, whatever it is. The 15th has come and gone with no announcements.

Another thread quoted mid december for first batch. Apple slowed down the tape out. So spon and a few others, will all ship in quantities feb through mar. Apr second gen around 0.2w/gh with as we all know, most bugs ironed out.

Mid December for ordering falls in well, the S3 family will be at the end of their, "Return over Power" stage, by the time delivery gets under way.

It sold out.  In alt coins there is a thread for it.

I was having a problem with my AntMiner S3+ that had become unresponsive and inaccessible after I ticked a wrong check box while trying to get fancy with the network config.  I was trying to connect the miner via WiFi, and also use it as an access point for my Raspberry Pi that's running a Gridseed, and I bridged the wrong two interfaces.  I've seen a lot of posts in this thread with suggestions on how to fix it, but they are all either incorrect, incomplete, or unclear.

First off, no amount of fiddling with the reset button did anything at all, and I tried for many hours.  Pressing the button once does nothing, holding it down for >10sec makes it restart as does double-clicking it, holding the button and then starting it up will just cause it not to boot.  Someone said to start it, wait 3 minutes, hold the button for 15 seconds, do that again, and power cycle it... which didn't work, either.

I was able to fix it by connecting to the serial debugging port on the interface board with a USB to serial adapter, and editing the /etc/config/networking file with the correct settings and rebooting.  The post that gave me the hint about the serial port was a little ambiguous on the TX/RX pinouts, so I wanted to post a pic that should be self-explanatory.  I'm using a Parallax 'Propeller Plug' that I got for about $10 when I built a Propeller on a breadboard.  The driver makes it show up as a regular COM port, and I used PuTTY under Windows to connect to it.  The pin headers are just sitting in there, the worst that might happen with a loose connection is some corrupt characters in the terminal.  The reset pin is not needed.

Hope it helps!

Watch for the next large PH spike which is due any week now. That will be your key as to someone "burning in" a first batch. By burning in I mean selling to one of the major players.

A friend mentioned that occasionally one of his AntMiners would randomly stop hashing, but would start right back up after restarting.  I thought it might be handy to write a script to do that automatically to minimize downtime without taxing the miner by power cycling it.  This ash script, triggered by cron, checks every 10 minutes to see how long it's been since the last work was submitted, and if it's been >10 minutes it will restart the miner and log the time in /root/watchdog.log.

Just save this as /root/watchdog.ash, make it executable, and add the job to Scheduled Tasks.

Code:

#!/bin/ash
# /root/watchdog.ash for AntMiner - 2014.11.26 - by b00m3rang

# You must run 'chmod 755 /root/watchdog.ash' or set +x in SCP client,
# and add the following line to "Scheduled Tasks" under "System":
# * */6  *   *   *     /root/watchdog.ash

# Assgn variables for current time and time of last work accepted
currtime=$(date +"%s")
lastwork=$(cgminer-monitor 2>&1 1>/dev/null | grep A= | awk '{ print $7 }')

# Calculate seconds since last work accepted
sincework=$(echo $((currtime-lastwork)))

# If no work submitted in the last 10 minutes, log and reboot
if [ $sincework -gt 600 ]; then
    echo `date` >> /root/watchdog.log
    reboot
fi

Let me know if you have any problems or improvements.

I think this is starting to happen right now, but it is too early to say if it is Sp-20 from Spond or "something new" from Bitmain.
We are currently at 310 PH vs 260PH yesterday. 50Ph is ~30000 Sp-20. I don't think that they have capability for such volumes, so my guess it is either KnC/Bitfury deployment or S5 from Bitmain getting burned in.

Accidentally (or not!), last coupon for Bitmain expires on Nov 30 and next day, Dec 1, is Cyber Monday.
Would be a perfect time to introduce something major...

>30% off Black Friday Deals

Special Sales for ANTMINER S4, 0.409USD/GH/s, FREE International Shipping. Shipping on Dec. 2nd

Might want to mention that you are forced to buy SIXTEEN units of S4.
Also that coupons are not applicable.
And finally that without coupons being accepted, that the price per unit works out to being $818. Which is $18 MORE than buying a single unit with a coupon.

Shipping appears to be included. For a change.
Customs fees I highly doubt are included. As usual.

Unless you are in the market to buy 16 units, this is not an actual sale. And even then you save very very very little. Basically cheaper shipping.



How about actually giving 30% off the price of a single S4, and still allow the coupons..... so it is not completely and utterly useless to everyone, as this so-called "sale" currently is.

+1 to upper post.

My bad.
It is more retarded than that.

You CAN use coupons. 1 coupon per 16 units.


Again, allow us to buy individually at the 30% discount..... because this is not a sale, it is a wholesale liquidation at best.
Failing that (as I expect you will) you should at least follow your own policy that you have force fed down my throat for so long..... ONE COUPON PER UNIT, AS PER BITMAIN POLICY.





EDIT* otherwise, please announce that S4 are "ON SALE" for $18 more than usual price, BUT the catch is you have to buy 16 units to pay more for them.

  BITMAIN - Please do not lie any more

This  is only free shipping , if you buy at one time 16 Antminer S4

You can use one 400 USD coupon per purchase 16 Antminer S4. One Antminer S4 price is 793 USD . It is not >30% off. This is  only free shipping.

Hold on champ.
Shipping is NOT free.
That is another one of their lies

After you work out the price difference, shipping is CHEAPER. It would be incorrect to describe it as free.

I think that your math is incorrect.
Regular price: $1200-$400 (coupon)+$160 shipping=$960/unit delivered to US
sale: $818/unit-$25 ($400/16 since you can use one coupon)=$793/unit delivered to US
savings per unit=167/960=~17%
however, you need to get 16 units, which is a deal breaker for me, but probably OK for some large scale miners.
