At a guess, the 'very low cost', would most certainly be having to buy an additional PSU, or several 1 kW PSUs ( for example ).

I would think it more likely that Bitmain will have an upgrade path to replace the cards with ones containing chips of a smaller process node (28nm).

better everyday ♥

Interesting. Be able to overclock to 2 TH/s just buying an additional PSU for a couple hundred more.

If that's the case, I have to get me one of these! Cool

A short good news for the S2 buyer is that we will let the S2 to upgrade to 1.8TH/s or 2TH/s at very low cost which you can only image now in the August or September. It still depends on many factors to let us achieve that and detailed plan needs to be drafted, But we are very confident that we can make it.

Just so we're clear, are you saying that you will provide a low cost way to overclock the current S2 to 1.8TH/s or 2TH/s in August or September?

:-)

Did you think will take Bitmain 3 months to do OC?

And also to be clear, even though August or September is a lifetime away in this game....

are you planning on allowing 1.8 or 2 TH using the same 1000 watts of power, or 1800-2000 watts of power?

I did not expect that I have to reinsert the cards, but now it works. Hashing with avg 1006.35 GH/s.

Just received my first S2 today, but I am wondering that I do not get more than 600GH/s.

I already have the latest firmware installed. Do you have an idea what might be wrong?
Kind regards

You should have 10 blades listed, I only see six. You should check to make sure all the blades inside your miner are connected securely.

Thank you, that was the problem

New price for AntMiner S2 1 TH/s Miner Batch 4: 2459 USD each one, shipping cost included.

Glad to see you have improved the design of batch 4 and secure the cards during shipping.

Hopefully still as planned the 28nm chip is still due to hit early June 05 I think you said in email.

I hope that you ensure batch 1 will be shipped secure and full design is taken into consideration.

Anyway good progress with the S2 in deign wise - it may have taken you 4 batches just to get it going but hope customer will be happier to know that less chance of a brake in transit.

just out of curiosity - has anyone calc'd what these need to cost to be 100% certain of a decent roi - not just breaking even

Well I'm a little more bullish on difficulty increases, given 11% per increase over the next few months.

Static:

Difficulty Increment: (?) 11%
Electricity Price: (USD/kWh) 0.1
Pool Fee: 2%
Hash Rate: (GH/s) 1000
Hardware Power: (Watts) 1000
BTC/USD: $433.989

@ $2000 Break even in 185 days, total profit before negative return kicks in: 0.314BTC
@ $1900 159 days, 0.57BTC
@ $1800 145 days, 0.8BTC
@ $1700 132 days, 1.033BTC
@ $1600 119 days, 1.263BTC

etc etc

ROI in ~4 mo IF S2 price at $1700, BTC stays at $438, diff rise~45%/mo OR price at $2059 (with coupon), BTC at $438 AND diff rise only 30% a month.
The best would come if $$ price for miners stays the same, but BTC rises sharply.
edit: I used $0.12/kwh electricity cost for this calculation because this is what I pay.

My current personal metric when paying $$ for any hardware is $1/GH. Not a whole lot of available choices at that amount so I try to get as close as possible.

Nice, they told me they had improved the design, didn't realise they had gone so far.

RE the old heatsinks, I have visions of them being delivered to the BITMAIN factory via tipper truck. Cheesy

hahahhah i can picture that visual way too easily! Nice to see they seem to have an improved method of keeping the cards held in place for shipping.

would love to see them put heatsinks like this on the S1 in order to cram 3-5 boards in the space of the current 2 boards
