ANTMINER S2 Discussion and Support Thread

[seriouscoin]

Just finished surgery on  batch 2 S2's after receiving them today. All is well and they are all hashing at around 1 TH/s. As others have mentioned before, you will need to open the unit to reseat some of the cards.


Are these upgradable considering the relatively  modular design ? The PSU can be upgraded and the "wafers" can be removed.  Your thoughts ?

LOL what? you know what wafer means in semiconductor?

I hope you meant "modules"

I guess you meant "sorry bud, im clueless but i can mug you off for no apparent reason"

Hey dumbass, why even open your mouth and confirm you're retarded?

Those module boards should never be called wafers. This is a wafer :


Now go crawl back to whatever filthy hole you came from.

S2 arrived today and was setup. Using teamviewer remotely (I am away this week and someone else plugged it in for me) I was unable to login to the webUI using root/root OR root/admin.

however, using SSH and root/root I was able to modify the settings   

Code:

vi /config/cgminer.conf

  with my pool info, and seem to be hashing away great now.

still cant login to the web UI, is root/admin not correct for batch 2 units?

As stated in the PDF, root/root is the login for the webGUI.  It worked for me.

didn't/doesn't seem to work.  i get a popup box to login at the ip but after 3 attempts am sent to a 401 page

To those with batch 2 units. Someone mentioned that there is a new power supply? How many watts now? and how many watts drawing at the wall? Have the new heat sinks improved cooling at all? What is new temp range? and range of temps on chips internally? New Case? Better / worst design? Thanks for any additional information.

for all your smartassery, you chose to get stuck on the word wafer rather than the entire remainder of a simple and clear question. You knew what he meant - wafer was just a mistake choice of words, to which you had no actual answer

The correct word would be blade/daughter board but that doesnt matter.

When you say wafer can be removed, its completely confusing and misleading.

If you dont correct them so they will keep using confusing words?

I did hint that he should simply call them modular board.

yeah what is the new

 'psu'

watts at the wall

db sound level

 what does it clock to? 

1100gh at 1100 watts vs 1000gh at 975 watts?

[googlemaster1]

Fuck, the case screws won't come off... anyone else run into this?

Maybe not everyone's first language is English? Besides, whoever can call it whatever they want - it is up to you whether you have the comprehension to get it or not. When I read wafer, I get it - you don't. Don't pick on words and throw a fit about it.

Back to the subject of this thread. Does anyone have any inside info on 3rd batch yet?

DO NOT use force , you might break the screw or worn its head off.

Use hair dryer to heat it up until its too hot to touch, then start unscrewing it.

Seem like you sound even more stupid to assume.

Here you are good members of the community.

Taken from an actual S2

Thank you, Thank You..  Cheap SD card failed on third reboot, it has been retired.

Too late, I brute forced the mother fucker.  I needed to fix the shit that mattered.

Edit:  Not getting rejects.  I'm a dummy.

I believe he meant new as in "not used". Many batch 1 S2s came with used PSUs (you could tell due to some dust build up), probably taken from their mining farm.

Seems like some of the batch 2 S2s have new PSUs... but they are the same model (1000W Enermax)

[xstr8guy]

I received my batch 2 unit, which started up right away, no problems.

Fans are apparently individually temperature controlled, with individual RPM displays on the web control panel, they definitely slow down when it isn't hashing or when you blow cold air at it, and run up to a moderate speed (not full speed) when it warms up during normal operation. Sound level is less than 2 S1s at the same temperature, might be similar to 1 S1, not sure.

Have not measured watts at the wall and reluctant to unnecessarily power cycle it (to plug in kill-a-watt) given comments about SD getting corrupted.

Temps showing a range of 42-47

Everything is stock.

Plan on ventilation. Lots of off-gassing. Definitely not used.

Sure smells toxic.  I may not wake up in the morning because of the fumes, lol.

No news ? Price cut / new update ?
The last price doesnt good in my country, and theres already three importer for 1TH from other brand with much better price...

[sbfree]

29 out of 30 blades is not bad...time to contact bitmain and see what they can do for me. I am just glad it wasn't the mainboard.

Dam that was a quick reply...I LOVE BITMAIN.
They are going to RMA it. Kinda wish they would let me pay for the blade/hashboard and send it to me while I send this one back. Then they cuold refund me once they have the bad one. but alas I am happy that they have responded so quickly. Thanks again BITMAIN.

[CroverNo]

New blades, new fans:

Make sure to post a new photo of the rig update - you seem to have so many of these S2's

Can anyone from batch 2 comment on the new design for securing the blades during shipment.

Hopefully Bitmain can ship these not installed!!!

Anyway nice update, cheers

[BitcoinPappi]

One of the S2' keeps shutting off after less than 3 hours then refuses to power on, unless I open the case and reseat the cards. It is currently running but might  shut off again.

*Not temperature related since the room is cool. The other S2 stays at around 53
