cgminer still appears to be trying to communicate with 192.168.1.1 though, and I can't seem to find where to set that from the command line.
Edit this file:
Code:
/etc/init.d/cgminer.sh
It's near the top, just enter your routers IP. You'll need to start it after and it resets after a reboot. You may need to stop it first, also.

I think overclocking is going to be extremely limited, with four TPS53355 per board, or one for 16 chips. On the S1, it's one for 8 chips.
Thats the detail I've been waiting for
*really hoping for a PCB photo still*The S1 could consume around 45W per group of 8 chips overclocked (overclocking pushed the regulator right to its limits, but the real limiting factor was the voltage being set to 1.1V - some people have apparently pencil-modded the S1 to almost 215GH/~470W, or about 60w/8 chips)
45W/1.1V=40.9A on a 30A-rated component. (bitfury h-boards faced very similar amperage limits when overvolted around 0.95V)
Its likely these chips run at around 0.8V and 1000W/640chips is about 25W per cluster of 16. That leaves a LOT of headroom on the regulators, but some of this is lost to the difference in voltage (more amperage). 25W/0.8V= 31.25A stock.
Presumably these should be able to overclock without any issues from the regulator. I imagine all other components are beefy enough also. I imagine you will hit hardware errors at 15-20% overclock as with the S1. These may even be capable of up to 1.5TH is voltage was increased to ~0.9V
I'm quite sure those puny heatsinks will not be enough when overclocked, 200Mhz+ will fry the chips unless some hefty cooling is applied!
If you want to overclock the BM chip, the S1 was made just for that!!
one way to add more cooling would be to replace the thermal paste with some geld extreme .. this will also reduce power consumption . copper heat sinks would probably work good as a replacement. i used copper heatsinks on the ram chips and replaced the thermal paste with geld extreme on the gpu's in my r9 290'x's ... any idea how big are the chips underneath those heatsinks ?? this trick would probably work on the S1's too .
Before I head to the gym, here's the quick video of the initial boot with sound so you can hear the fans. http://youtu.be/sQYtbtsyKdU
Aaaaaaaaand here you go.
The Power supply keeps cutting out in 1 machine, I didn't have a spare PSU, so I removed 2 of the asic blades to bring down the power draw, we'll see if it stays alive tonight.

you can cool those chips several degrees if you add the small aluminum heatsinks to them. i added those aluminum heatsinks to my S1's and they are about 2 to 3 degrees cooler without any airflow. add airflow and they will cool even more. if were to use copper heatsinks would cool them down even more i think although i can't prove this because i have not tried copper heatsinks yet.
BITMAIN: please put some Fragile stickers on the batch 2 orders before you ship them... they are obviously not as tough as the antminers.
Many thanks!
Many thanks!
You're confused if you think shippers pay much attention to fragile stickers. You need to pack up the items so they don't get damaged from handling that doesn't damage the packaging.
My S2 is working now!!
I noticed a chunk of glue(?) in the slot with the main card. I removed it and reseated the card and now everything works!

I have some glue on mine too, but it didn't interfere, and there appears to be something under the glue as well. By the edge of the tab, it looks like its been partially cracked or added after the fact or something. The pictures didn't turn out great but you can at least see the glue on both sides. I'll take it out and snap another later tonight, but it works solidly so I'm going to ignore it for now.

As for the fragile sticker, the only thing on the box besides the tracking/shipping label is a big blue sticker with a black D on it. Which I'm guessing is for http://en.wikipedia.org/wiki/ORM-D that? but it just a D and nothing else.
It's just a rework of the board. If you look closely, a trace has been cut and a jumper installed. The hot glue is there to help keep the wire down and try to keep other stuff from snagging on the jumper wire.
Ah. Thanks for the clarification.
How did everyone change their IP for cgminer? I've edited the IP and gateway settings, and that seems to be fine.

Has anyone tried the new firmware, yet? Any idea what it's supposed to fix?
https://github.com/AntMiner/AntGen1/tree/master/firmware_S2
https://github.com/AntMiner/AntGen1/tree/master/firmware_S2
Well I for one hope it fixes the reject rate 53% pool rej
Its bad enough paid a premium just to have to put it back together like a avalon clone after shipment.....
Tweaks to get it running after painstakingly putting it back together havent bothered to email bitmain they havent responded to me after they fubared a shipment back in february
Maybe their last harrah and pulling out of the market ....used power supply from their farm no less.
What a joke should have gone Dragon for 30% less at least I get paid to do all this extra shit
When you overpay for a minor every hash in first two weeks counts losing a ton of hashing like the shipment fubar in feb glad some of you have had good customer service perhaps I was too professional with them maybe I should have yelled like a little bitach

Quick Q. Did you guys who got B1 get a shipping notice from Bitmain or was it marked shipped on the website? Any info would be appreciated, thanks!
Received email... twice

If anyone is wondering, I'm seeing 10A @ 208V for two S2 units on my PDU.
What PDU are you using?
Just received my lone S2. I can confirm that the straps on the box do nothing but entice the driver to sling it around 1-handedly as I watched the man grab it and bounce it off the 2-steps of his truck. The package is well worn around the edges for just 3-day trip and has nice rip into the side. Unboxing now. Bad note, I can hear things rolling around inside the box already. 
Do any of the deliveries have a fragile sticker on the box at all? It doesn't sound like they're being handled appropriately.

The two Ethernet lights on the outside of the S2 and the two on my router are always off, when it is powered on.
Do you mean the internal Ethernet cable that is attached to the main (middle) board?

8 of the 11 cards were not seated properly. 
However, after re-seating, there is still no display and no lights on my router from the Ethernet connection.
I've already done a second pass at re-seating, and the internal Ethernet and ribbon cable are connected fine...any other ideas?
Since the display isn't lit, does that suggest a power terminal isn't connected or that the main board is fried?
At least the fans make an impressive sound.
Check that all cards and cables are seated properly.

I got my S2 today.
However, the display does not light up. Although the fans do turn on and I can see red lights inside it.
Also, the Ethernet is not detected by my router.
So the consensus is that I should open it up and see if anything needs to be reseated? Will this void the warranty?
Thanks!
