Guys what is the capacitors mod needed for?
Usually they're to reduce the ripple voltage.

how much the price declared by bitmain for custom purpose ?
and what is the description ?
is it still like S1 which is "Computer Game Gateway" ?

I see now there is a way to transfer coupon codes. I have 8 S2 coupons and willing to give them to someone who can use them, in exchange for a small donation in BTC I suppose. PM me with considering amount you're willing to donate for these coupons.
fyi, regarding the message I posted earlier about only getting ~920 gh/s with my S2. It seems that only happens with p2pool. I get the expected hashrate with Eligius. Furthermore, it's not just p2pool reporting it low, the S2 itself reports it low.

I wonder what they are planning for the S2 upgrade they said.
Just took possession of a new Bitmain S2. Capacitors are installed on the blades and the physical design has been modified to include a card hold down front and back. Also has a cutout in the side for the PSU intake. Everything arrived intact with no loose boards or other problems. I am working on setting it up now. Ethernet isn't being cooperative … checking cables etc.
I love the Antminer logo and Bitmain name embossed on the cover
Unboxing photos to follow once its running.
[edit]
I'm in (ssh) … loose ethernet cable from the controller to the front panel. I seated both ends with a little push and everything is now good.
Can't wait for the rest of 'em to arrive.
[edit]
A few minutes later - hashing at 1032.12 Ghs, all ASICS reported good.
Such a pleasure doing business with a company that does what it says it is going to do when it says it is going to do it AND delivers great products from stock. Thank you BITMAIN.

Is the PSU inside still the Enermax 1000 W?
Thanks.
Yep, afaik they are still using the same platimax model

just want to say, when the sd card seems corrupted... i have found and been confirmed by others that just pulling it and reinserting it is often enough to get it back online.
some have done so with power on, i prefer to power off, pull, reinsert and power on..
so far so good.

yes, it is hot and sweaty. pull it out , and put it in.

I no longer have any Xs or dashes on my S2.
I have a 1300w gold PSU in it.
I'm still averaging 923GH/s. Any ideas why so low?

Thanks for your nice and detailed reply.
Useful but what UPS would be used for an S2?
At what extra cost?
At what extra cost?
You would only need to provide wattage for about 45 seconds, plenty of time for a monitor to fire off a script to ssh into the box and issue the shutdown command. Again, not elegant, but certainly possible. The extra cost if you don't have the kit laying about is probably not worth the investment, but it you're hashing in an environment that has frequent power issues it might be. A RasPi could do the work, and a consumer rated UPS would buy you the time you needed, although it would need to be large-ish.
In my defense, I was just posting the solution to the card corruption, not the power grid.

That said, it's not an elegant solution. I believe a firmware refactor could provide us a solution that will make power events less volatile, but that's (generally) in the hands of the BM devs.
You are welcome , but hell no , UPS is not a solution.
Sure it is, power events can be scripted--I was editing my response when you posted, but Google has the hook up: https://www.google.com/search?q=using+a+UPS+power+events+to+trigger+a+script

Exactly, what is the solution to that?
Uh, a UPS? I thought that part was slightly less technical, my apologies!
Try here: https://www.google.com/search?q=using+a+UPS+power+events+to+trigger+a+script
Exactly, what is the solution to that?
SSH into the box and issue the "shutdown -h now" command at the prompt before flipping the switch on the PSU. I've power cycled my S2 a millionty times this way with zero corruption.
SSH user is root, and the password is admin. You can use PuTTY in windows (for free) or the terminal in OSX or Linux with the "ssh [email protected]" to connect.
That is good advice, but it doesn't help much when the power goes off unexpectedly.
