ANTMINER S2 Discussion and Support Thread

[s1gs3gv]

Speaking of overclocking, the S2 seems to be happy @ 225mhs. I swapped out the Enermax for an EVGA 1300 I already had, added an entry in /config/asic-freq.config for 225mhz and am now running at an average of between 1.1 - 1.14 TH with a chip temperature increase of ~ 2-4 degrees. WU has gone from just over 14K to just under 16K.

I want to let this run a while before I try for 1.2TH

// edit: I am seeing apparently very high rejects @ 1.1+

[dlowings]

Did Bitmain take a walk off the deep end ? Did they go full retard on the price ? Not only is their kit roughly the same price as the full unit use to be, the full unit is now TOTALY overpriced more then it originally was …


This folks is what FULL RETARD looks like …..

There was a big conference of chinese mining manufactures. Im sure they discussed fixing prices to maximize profit.

This is part of their culture, "sadly"

CLEAR case of demonstrating that its all about the dollars and less about the consumer .

Remember everyone sold their $400 good will vouchers so you can buy these at $1860 essentially.

what code and timeout values did you use? can you post or provide a link to. Much thanks, I've got evga 1300 and might give it a shot.

My machine seems to already overheat periodically at default settings, though. I also noticed that once fans speed goes up, hashing goes down, which is reasonable as enermax has to use more power to fans, hence less for hashing, at least this is what I thought.

I was thinking of getting a "naked" kit (not at $2260), then don't even use the default fans and instead use a couple of powerful fans like Vornado to cool the boards, perhaps make a simple wind tunnel. It just might work.

I think most, if not all of the $400 coupons are now expired. $2260 is a steep price to pay for a 1TH mining kit without a case or PSU.

[PsychoticBoy]

YUP 

Instead of improving their design, they just removed the case and made it an even worse miner
Datacenters will not be very impressed with those miners in their Racks

I graded Bitmain 8 out of 10 but now they will nearly get a 6.

Keep up the Ughhhum Great work and you will end up like KNC.

They are obviously selling off their remaining stock of parts before introducing the S3.

0881 and 65

It is unclear to me the role that the timeout value plays in the calculations, so 65 was just copied from an adjacent entry. It may not be correct for 225mhs.

I started seeing very high rejects and errors so I'm back at 196 for now … YMMV

I sell s2 coupon pm me

How much btc do you make every single month if you have 5 units of AntMiner S1

1.43 according to https://bitcoinwisdom.com/bitcoin/difficulty

But don't forget difficulty rises approximately every 12-13 days

More like .78 from June 1, to July 1.  assume 15% rise jumps  and  .15/kw electricity

they must preparing something new as Bitmain no longer has the S2 complete
They should offer a all in one miner for the not so experienced miners.
55nm is old tech must be something new
the good thing is that they never stop to surprise us either with the price or product

This kit is just badly priced. If Bitmain priced it reasonably (about $1500) it would probably sell. Considering that they save significant money on the costs of a case, asembly time, and the size/weight of the shipping package, it must cost about $200 less than the S2 did.

really looking forwards to the next gen, since i feel these kits could do very well with a 28nm chip. The current prices of both the S1 and S2 kit are out of whack with reality and the SP10 units are becoming a better GH/$ and GH/W

Agreed. The main downside of the SP10 is noise, but if one can deal with that, the SP10 is now a far better buy than the S2 kit priced at $2260.

S2 was not a bad deal at the group buy price of 1650.

I hindsight, the $1650 S2 group buy was a great deal. I managed to pick up a few units.

[NorTiaN]

WTF? They'r selling DIY kits now??? They want to become what? Datacenter exclusive???

Yeah missed that GB - looking at the SP10...

4.8115 BTC (which includes shipping) for 1.4 TH/s

Still too high for ROI. Stuck between a rock and a hard place - sit on the coins.

What price would please you for an SP10?

I'd jump in for 4 BTC (including shipping).
