A couple of EVGA 1300s and some bigger VRMs should do nicely ...

How do plan to handle up to 2.6kW of heat with the current cooling setup of the S2?

Well, for starters a 2TH S2 probably wouldn't generate 2.6 kW of heat, more likely ~2KW (I haven't done an analysis), but how about modifying an old fridge with some power sockets on the back wall ? That should satisfy the 'house friendly' crowd and the 'there is no way' crowd at the same time LOL

In any case, doubling the hashpower is an extreme case … it would be nice to get an extra 40% out of a machine which costs less than $2000 retail and whose price in a group buy is significantly less. The ideal scenario would be to OC it to the point where it could still run on a 15-20amp 120v circuit. Think an SP10 level machine without all the noise for ~$1600 ...

I was just about to ask that. Furthermore, it will no longer be house-friendly and would only be relegated to the data center.

hmmm …. the S2 /config/asic-freq.config looks just like the S1 /etc/config/asic-freq ….

I wonder what they are planning for the S2 upgrade they said.

Probably an OC to 2TH. After all these chips are only running at 196 ...

There is not enough power available to OC the unit anywhere near those levels.

Guys what is the capacitors mod needed for?

Usually they're to reduce the ripple voltage.

Double your Personal Bitcoin Funds.

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.

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?

Useful but what UPS would be used for an S2?

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.
