There is NO WAY I am going to be the first to overclock. Way too loud already, Way to Hot, and Way to Already Maxing Out the Power Supply!! - Just nice to know its there.

Is there any CE certificate link for Antminer S2? It may be very badly needed in some EU regimes.
Not that I've seen.

I wouldnt overclocking it either. You mind as well take a blow torch and see if it burns or not. Esp, when setting conditions can be based on where you live in the world. It is good to know that its there, but most people who do this dont do it correctly then lose their mining gear. Despite being instructions provided.

Hmmm, Well I found the overclocking settings.
Heh.. I wouldn't try without making sure you got more headroom on your PSU. I'm thinking a 2KW server power supply. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) and make sure you got plenty of cool ambient air going in.. cause it's going to be toasty coming out.. Looks like they are running them at 196. Can you take a screen shot of what it looks like? That is to say is there a higher option setting that you can just remove the ###?

Yes... but without: 1 - bigger psu 2 - bigger heatsinks or significantly cooled ambient air I would not even consider this.

Well, here we are All three units would not power on, I had to remove the case and plug the controller card back in. Also, 2 had the ribbon cable to the LCD unplugged and one had the ethernet unplugged. The one on top is missing screws, including screws for the bracket. It also has a nice dent on the bottom corner under the middle fan you can see. That was not caused from shipping, and was not caused by me. Once everything was plugged back in (and the asic cards reseated as well) All is working fine. The middle one shut itself off after 5 min of running without the cover on, I'm assuming it was due to over heating. But we'll find out soon enough! ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FnAbpfPw.jpg&t=665&c=Z0ndqTVrZpJqjg)

Well, sucks to be me, my 4 batch 1 units have only just left Shenzhen. Not happy considering they are now estimated to arrive the day before my batch 2 units are supposed to be sent out.....

Has anyone been able to get these to work on a network that's other than 192.168.1.*

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.

Well, mine won't connect at 192.168.1.99, and according to an IP scan there's nothing from 1.1 to 2.254 My laptop detects the board and the lights on the BBB work, so it doesn't appear to be a hardware error. Did anyone else get a unit with a different IP?

"My laptop detects the board" What do you mean by that? Check all internal connections. I had loose boards, the cable to the display was disconnected, and the internal ethernet cable was not completely seated to the panel jack.

Thats the detail I've been waiting for ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) *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
