Hard to argue with the S1's being cheaper, I clocked one of my S1's down to 200 which brought speed down to 107 GH/s but also dropped power to equivalent with S2's W/GH. Knowing that it would seem S1's will be viable just as long as S2's. That is unless mod'ing can get us more then 1100 reliably. As far as rack space goes, I have been able to mount 6 antMiners within a 4U case, reversing the fans on "hotside" of cabinet, cut the BLUE wire to fans, and have seen NO meaningful heat differences between "coldside" and "hotside" of the cabinet. To be clear I am running 6 S1's within the same vertical foot print as 1 S2, so even when the time comes to under clock the S1's, the S1's will produce 1200 GH/s for the same 4U's..

Just out of curiosity, has anyone purchased the S2's at the $2199 price even? I'm tempted to if BTC reaches $480+ in the next few days.... thoughts?
$2199? They are currently listed at $2599.
Alot of people who previously purchased an antminer s1 or s2 got a $400 coupon for a future order.
Ah, sure enough. I initially saw a $100 coupon for an S2. Looking again, they are now $400 coupons.
Yep...$2,599 - $400 = $2,199 ...or 4.93 BTC at the moment...
But we can buy 5 x S1 for 2.5 BTC...or almost 10 x S1 for the price of one S2 right now...
I should wait for S2 price to come down ...like $1.599 ...by the end of May maybe...

1100GH is possible without pencil modding and 1.1% error rate. any frequency settings higher, and the error rate is over 2% and the unit can even fail offline and need a power cycle (not sure if the unit or the psu caused this).
I think with the correct resistors identified you could get up to 1400GH/2100W, but probably not without pci entenders and much more cooling. 1280GH (~250MHz, ~1600W) is probably the most you could achieve with pencil modding while keeping all the components in the case with the lid on.
$2200 with coupon is not a bad price. for those who have limited space or larger farms it is better than most of the competition products. For those with shelving units and more space though, the S1 makes a lot of sense and can be undervolted/clocked when the time comes in 1-2months to improve the efficiency and keep them profitable for a few extra difficulty jumps
+1 for S1...that's my plan...2TH of S1's now...1.5TH with reduced power later...like by 4-th of July...
After that...who knows...we'll see...

This is true, but don't discount the price of reliable power and space for the S1s in your calculations. It depends on the environment these devices are going into, as well as the bottom line. 5 S1s are cheaper, even with additional PSUs, but the management of these devices is greater as well. Pro and cons on both sides!

They should update your account for a coupon, there is some discussion as to how long it takes.

I bought an s2 recently. I did not get a coupon. How do you access to the coupon?

First overnight report of my Batch 3 running on stock settings, stock firmware and stock power supply. Hashing at 1025 to 1080GHs solid, no beeps or loss of power.
Batch 3 S2 replaced 5 BE Blades running on a backplane
and heat output is significantly less. Compare that to 50GHs on 5 BE Blades with just about 80% of a S2 power consumption and twice is much heat.
I'm happy with my S2 so far, it is a little loud though but I can live with that.

thats really good speeds - my batch 2 ran at something like 980GH stock. did they change something for batch 3, such as a higher frequency or slightly increased voltage?

Has anybody tried write protecting the SD? Don't now if that would help with the corruption, but it might.

I tried the image from 1l1l11ll1l but for my it did not work.
win32discimager writes for a few seconds but after that i can't read the sd card.
There was also a other image ( updated? ) and that one worked.
It took a few minutes to write that one.
I have just send a email to bitmaintech to ask about this booting problem.
When i have found the problem i will post it in here.
You will probably need to format the SD card properly before writing the image or it might not work (it's partitioned). Download a SDFormatter to format the card and make sure you see the full memory available before writing the image with win32diskimager.win32discimager writes for a few seconds but after that i can't read the sd card.

Sounds like you got it working though... if you did, you should make an img of the working card and write it to a spare or at least to disk, to make any future resetting go quicker.
btw, the sd card i used came formatted, i will try SDFormatter tonight to be sure.
Thank's for the advice.
Make sure they are class 10 sd cards. That worked for me.
I had the same problem on my batch 2. Three of them just did not boot when restarted. Even after replacing the sd cards with new ones and the image provided by 1l1l11l1l (thanks!) still no boot. But they were not class 10 cards. I don't know why but as soon as I put in a class 10 card in, with the same image, it worked without a problem and on all three.
Good luck
same for my bitfury system a few months ago. the original SD corrupted after a few weeks and i could simply re-image it. however, after a few more it spat errors at me and would not read, format, or reimage. I switched to a new card of the exact same brand/size/speed and the same thing happened after a half-dozen power cycles. I switched to an 8GB class 10 and no issues ever since
Yes i know, i mined the coins with S1's to buy the S2 on 16-03 for the second batch.
The S1's where great but this
I hope it's something i can solder back, that won't be any problem for me.
Even if it's a bga or something like that.
On the controller board are 5 led's, only one of them is green.
it's the led with R41D5 marking next to it.
Any thoughts?

look up support for the beaglebone black since that is the control module. its possible you need to swap in a new controller and/or sd card (probably <$50)
The real question is: why should anyone have to swap out anything for an expensive piece of equipment that was obviously poorly tested, and used a shitty microSD card in the first place.
Also stop hiring monkies to throw your packafges onto your planes....do they think there are pilows inside an 18kg box? what a stupid system, at least work out the delivery part so all the units dont come to people in pieces.
Fragile, or this side up, doesnt mean shit to these carriers, even if they could read them or understaing which way an up arrow is suppposed to go. Put it in chinese then, but I dont think it will make a difference. seems like whoever he is using to ship these units is the cheapest carrier he could find as seen in one of theose animated gifs i saw a while back where the monkey is tossing these large heavy boxes carelessly on to the conveyor belt with half of them falling off.
Good work Bitmain, way to kill your entire business operations in one clean sweep.
Maybe you shoulod lower the price again next week and try and get some more suckers to give you money.
why so negative? I understand lots of machines arrived damaged - and i can understand why, particularly if they were shipped on thier sides rather than rightside-up or even upside-down. Hopefully bitmain sees this and is working on it. ever new generation of equipment will have its issues. The first few S1 batches had various issues and non-ideal traits such as the lack of pci-e connectors.
UPS is a reasonable shipping company, not much better or worse than purolator/dhl/fedex/etc. They deliver quickly and at fairly low cost - The S2 just needs an extra layer of protection to keep the boards in place if shipped on its side (such as a cross-bar made of metal instead of foam).
My unit arrived just fine, and is right now hashing at 1100GH
I just had a power outage and it booted up no problem with the card supplied with the machine... go figure
