Has everyone who ordered batch 4 gotten their tracking numbers? I am still waiting for mine. I sent a request but have not heard back from them yet....

UPDATE: I got it. Just a minor mixup with my info. But they sorted it all out

I have, ordered on the 5th.

Sonofabitch power supply gave up at midnight last night (perfect time too), so now I'm running on a 750W @ 700 Gh/s

Since these are basically the same chips as the s1 why is it so hard to overclock these to 1.2th/s? That is only 20gh/s per board.

I would think down the road we should see better results pumping these up.

[tzortz]

It has been done already. Klondike, where are you?

 first off  you blow up the  stock psu.
  so you need to pull the psu and put in one like this:

adds to the roi.

next if you one from above  and oc the gear you will overheat it. So you need to improve cooling.  pull the fans put in ones with more air movement = louder and ac the room.



so squeezing out that extra hash will cost more then it is worth.

I hope this is an isolated incident with the stock power supply. I think Enermax makes the most reliable power supplies around, I have them in everything and wouldn't buy anything else even though they cost more than similarly spec'ed units.  Never had a failure and never lose sleep worrying about my power supplies.

Bitmain has organized to send me a replacement psu and power board on Monday... pretty good service, even on a weekend!

May I know your reasoning ?
Why not buy 6 S1 ?

[alexrossi]

May I know your reasoning ?
Why not buy 6 S1 ?

Cause they have double power consumption, so unless you have free power S1 aren't making anymore an easy ROI

here is my math 0.492 BTC-0.05 coupon=0.442BTCx437=$193
expenses for 3 mo=$193+3X$36 (electricity at $0.12/kw/h with 410w at 375mhz)+$70 PSU=$371 in expenses.
revenue: absolute max of 0.87 btc in 3 mo (with 45% montly diff rise or ~13% each period)=$381, essentially=expenses
Conclusion: unless BTC rises, it is difficult to make any money by mining using S1.

 It is rapidly approaching the price-point where it will not make sense to purchase 6 x S1's, as you will need an additional purchase of at least two 1200W power supplies to power all six units.

 Given the S2 ships for $2094 (after $400 coupon application), and does ~1w/gHs for 1tHs total, it's not a clear decision either way.

 Personally, I'm starting to phase out all my S1's for S2's and A1 clones. Would be nice to acquire a Spondoolies unit in short order...

You can underclock 4 Ants on a 1000W power supply for cheaper still.  140 gh/s each.

[Xian01]

You can underclock 4 Ants on a 1000W power supply for cheaper still.  140 gh/s each.

 Even then, you're still off ~ 0.8 BTC-1BTC difference between the two options which is approximately eaten up by purchasing a couple adequate power supplies for driving the six S1's.

 Like I said, it's a very close call either way.

I coin toss at $438/BTC. Much better at $600/BTC. Great investment at $700/BTC.

I have 7 s1's

I have a friend with an office space .
So free power not stealing it either. Story is long and complicated,but 4 people split the power bill and the building.  He has paid 1/4 of the power bill for years. While spending about 5% of the power. So adding an s-2  will mean he will finally get his fair share of power.

   so an s-2 with free power is very tempting. S-2 is closed cased no shock issue..  He need to upgrade his internet. They did the work on Friday and Saturday .  I am bringing one of my s-1's over and seeing if it runs well. If It does I will get an s-2 sometime this week
