ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382

[Gogreen]

Stay on topic go spam someplace else no one wants to enter your raffle we want to talk about the S3 not scamming people into buying your raffle tickets

and the winner is number ?

Back to topic.

  I was wondering if  anyone got a coupon or if anyone has ordered in batches 1 and 2.

I am hoping I get it around July  9  10 or 11    as sometimes it comes early.

You wish !

Don't forget to open the casing to clean off the ducts LoL

Made my first bitmain order. Anyone know how long it takes to get a payment verification email?

they will rely that it is comfirm if u email them with your detail ,

[taipo]

I think there will not be coupons for the S3s

...at least not now...maybe next month...

Got this in an email from them:

Hi,
no coupon for S3:)

Best Regards

BITMAIN

I don't think that I ever got a 'payment verification email' from Bitmain.  Just log onto your account on the Bitmain web site, if on the order list it says that the status is 'Paid Unshipped Valid' then you are fine.  If you click on 'view' for that order, you'll see the order details and that should say 'Pay confirm'.  I usually print a pdf copy of the order 'just in case'.
When it ships, sometimes you may get email notification, however the order status on the Bitmain page will provide the shipping status and tracking information, which you should then follow with whoever ships your miner (my preference is UPS, as they have been much more reliable than DHL, usually UPS delivered it ahead of the projected ETA).

Suggestion for good power supply for s3

thanks

I've got two over-clocked S1's running off a Cooler Master V1000 (stateside SKU=RSA00-AFBAG1-US).  It has fully modular cable design and eight PCI-E 6+2 pin connections.  Paid $209 USD new at the local geek shop & it works flawlessly, I would definitely buy another one.

Has anyone heard when Bitmain might release the S1 --> S3 upgrade kit they talked about, at what price.  Sorry if this was already answered but at 70+ pages I don't have the time - or attention span - to read the entire thread.

Regards,
JR

Cosair RM850 gold for 2s3 is very stable.

That's about the same response that I got from them when I asked about S1 coupons back in April of this year.
Then at the end of the month they sent me 1 S1 coupons and 2 S2 coupons so basically anything could happen.

Just to know if this S3 ROI or not, made simple maths:

lets imagine i buy 50 S3.

50 S3 = 23900 GH/s without overclock
25 pairs x 1,48 BTC = 37 BTC = 23888.57 $

And for power costs, i calculate around 34 $ / S3 without overclock / month(costs 0.18 $kwh). So 34 x 50 = 1700 $ / month all together.

Right now, if you have 23.900 GH/s you earn / month --> 14083.18 $

So imagine:

14.083$(earnings) - 1.700$(power) = 12.383 $ / month.

We have difficulty increases, yeah, but right now, i see next difficulty will be 15998489889.0 / -4.9% [est.], is that correct??. Difficulty decrease?. Anyways, i think S3 ROI, but of course im just a noob here and its just my simple maths  

I dont have to buy PSU also, as i have 2 corsair CX750M from my S1´s

Hi
Does anybody have cupons for S2 (PM me plaese if you want to give them away).
Thank you

I don't understand why people keep referencing this website.  I proved it was wrong last change.  It called a 30%+ increase 3 days before the change, when the numbers showed about 24% - 25%.

Right now the numbers are showing a decrease in difficulty.. but this website seems to be arbitrarily picking 11% increase.

It's not arbitrary at all. Bitcoinwisdom bases it's estimation on the time it took to find the last 2016 blocks just like bitcoin does.

Do the math yourself.  I did for the last change, and proved it wrong.

There is no such thing as "doing the math".

What you are doing is called astrology.

Quite the contrary.  There is such a thing as doing the math.

Get the timestamp of the last block solved before the difficulty change.
Get the timestamp of the last block solved.
Subtract the 1st one from the 2nd one.
Divide that by the numbers of blocks solved since the last change.
That's how often the network is solving blocks since last change.

You'll see that number works out to 10.59 minutes per block so far. 

Last change, 3 days before, bitcoinwisdom was saying 30%.  My math was saying 23.6% at the time, and I figured it would likely increase a little more, but certainly not 6% more.  Actual increase?  24.93%.

If it is using the last 2016, that's why it's wrong.  The last 2016 only matter when it's 2016 blocks since last change.  It should be using the number of blocks since last change, and it's clearly not.

A single sample will not prove you true or its not scientific.
It can be coincidence. You put you current calculations and look at next change.
At the near of difficulty change they too come to the same %.

This is just a much less accurate way of estimating the hashrate.

Everyone knows that difficulty adjusts to 10 minutes per block based on the time it took to find the last 2016 blocks.

With your estimations you will always see a ~0% increase immediately after difficulty increases because that is the whole point of the difficulty adjustments.

Right now your "math" is suggesting that there will be a 6% decrease. I am willing to bet that that will not happen.
