AntMiner Jumper Switch- Bitcoin Miner Accessory

Global Sales start on July 31, will close on August 6th. Shipping starts on August 27th.

PC Power Supply has been widely used to power Bitcoin Miners, but users have to use the paper clip or other metal line to short blue line and black line of the PSU 24 pin interface before powering Bitcoin Miners. It is troublesome thing to short lines, and may lead to unstable power supply.

Here we are glad to introduce a new Bitcoin Miner Accessory - AntMiner Jumper Switch, which is to provide a convenient and effective method to start PSU. Only need to connect it to the PSU 24 pin interface, then press the “Switch”.

Only Available at http://www.bitmaintech.com

Very nice and simple design.why a minimum of 500 to be bought though?

Yeah - a "20 or 50 pack" would be good...

If enough people are interested, I'll order 500 and parse them out in bunches of 25s. I've been meaning to work on my trust rating anyway. Anyone interested?

My chips are OK now, but what does it mean (the same board, top in this list) when the board's temperature value change it's colour from black to this under-red colour? I saw it at temperature value 52, 55 degrees, without any "x".

One of my boards has 16 bad chips. Does anyone know if this is replaceable or is it still within standards? I tried e-mailing [email protected] last week but never got a response. I never get the full 1 Th/s I'm usually at 970 Gh/s then it will creep down to 930 Gh/s.

The weird thing is that when I do a full power off and turn the s2 back on it will show all chips working for 12-24 hours then the first 16 chips on the board turn to x's as seen here:

I've seen a few other people in other threads who experienced the same problem but I don't see any posts about resolving the issue. I've tried swapping the bad board into a different slot as well as pressing all the chips on the board. So it's not a problem with the slot and is definitely something wrong with that board.

I would like to replace two front fans with Noctua NF-A14 PWM, and original chinese fans will be spare fans... They are too hot at their center after rotating for a while at 2400-2500 rpm, has anyone tried to grease them?
What would you say about Noctua fans? Is it good idea?

What does it say your speed is on the pool? Could it just be a error being reported to the LCD?

Sure it can be a firmware issue while at ozco.in side it shows 1,104.92 GHash/s.

Quote from: kanes on July 24, 2014, 02:19:50 PM

is it safe the change of firmware? What temperature you got with that?

At least the process goes smoothly. Cheesy

The temperature of the boards is about 47-50ºC, 54º at hottest (upper in the list) board. All that is displaying in web interface. LCD shows 49.8ºC. S2 is now at my home, this evening I'll move it to my working place where the air conditioner can make an ambient even 19ºC...

S2 is discontinued?

Sorry, what do you mean? It reboots after firmware upgrade, if you mean that. Grin

Hello everyone,

Last Batch of AntMiner S2 1TH/s Miner is Sold Out.

Will be Antminer S4 ?

Could be... S2 is now gone from the website. Maybe they are re-engineering the S2, rumor had it that some people got S2's that hashed at 2Th, so I wonder if the S4 will be 2 Th/s. That would be a start, but they need something to compete with Spondoolies which I think is starting to eat into their marketshare. As soon as the S3 sold out in Batch 3, the SP30 (6Th/s) September batch sold out.

The SP30 September batch did not sell out. Spondoolies stopped selling it when they got chips, assembled working units, and learned that it would not meet the advertised performance of 6TH/s at 2500W.

Kano ?

Kano, works on the cgminer team.
Edit: here's his github page for the S2: https://github.com/kanoi/cgminer-binaries/tree/master/AntS2

Kano's firmware shows now 3 Th on LCD screen of my S2... And 6233 for last 5 minutes.

And I still can not change default passworb via web-interface...

Will someone kindly post the default asic-freq.config file (full contents)? Thanks.

Code:

root@antMiner:~# cat /etc/asic-freq.config
package 'cgminer'

config 'asic-freq' 'default'
#option 'freq_value' '4f81' #400M
#option 'chip_freq' '400'
#option 'timeout' '35'

#option 'freq_value' '4d81' #375M
#option 'chip_freq' '350'
#option 'timeout' '40'

#option 'freq_value' '4d81' #350M

option 'timeout' '40'

#option 'freq_value' '4f02' #193M
#option 'chip_freq' '193'
#option 'timeout' '85'

I just noticed those funny characters at the top - but they are really there - checked 2 miners

Yes I see them on mine too. I'd deleted some of the entries and needed the full list without doing a factory reset, which resets the ipconfig back to static.

Really appreciate it. Thanks
