Biffa - none, and the heatsinks seem much better milled. no rough edges

tzortz - there u go

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

Was there still TIM oozing out the sides of the heatsink and smudges and smears of TIM on the back of the boards?

Has anyone paid by Bank Transfer for an S2? I did for this latest batch and since sending it have heard nothing from Bitmaintech despite numerous emails trying to check they have received the payment OK. Maybe a nice shiny S2 will arrive on my doorstep in the next couple of days but it would be nice to know what is going on!

batch 4 arrived just now - set up was a breeze.

nice new board rails - all metal and secured with 2 screw down guards.

all boards were out of their connectors but the guards kept them secure.

wider fins on the heatsinks, better led screen, can view from wider angles.

vent hole in side with PSU breathing but temps are identical to B3 - hashrate seems a bit more variable but overall SLIGHTLY better.

i might post pics if i can be bothered later - gunna let it settle in first...

oh and nice 'Bitmain' antminer impression on the lid but whatevs.

I suggest checking the pins inside the pci connectors, some of them could have been bent by the cards sliding in and out...

forgot to add paid just over 100USD in UPS fee(s).

I'm sure the forum would like to know what kind of SD card was used... if you happened to look just for funsies... With the trouble you've had with these things though, I would hate to make you ask to check ;P

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.

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

http://www.amazon.com/EVGA-SuperNOVA-1300G2-ATX12V-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?ie=UTF8&qid=1399719720&sr=8-1&keywords=evga+1300

195 usd

or thishttp://www.amazon.com/SeaSonic-ATX12V-Platinum-PLATINUM-1200-SS-1200XP3/dp/B00JG5LSN8/ref=sr_1_1?ie=UTF8&qid=1399719766&sr=8-1&keywords=seasonic+1200

290 usd

or this

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182063

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.

the psu is underpowered. use 9 boards or buy a better power supply. many many many stories about this psu not cutting it in this piece of gear.

New price for AntMiner S2 1 TH/s Miner Batch 4: 2494 USD each one, shipping cost included.

the price is getting closer for me to pull the trigger. it is now 2094 USD after coupon

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

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

Me too. Can I pay by bank wire transfer ?

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

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.

Why not buy 6 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...

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.

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.

the psu is underpowered. use 9 boards or buy a better power supply. many many many stories about this psu not cutting it in this piece of gear.

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

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