Its still double the price of the S1 per thash even with the coupon. S1 is the best bang for the buck right now.

And S1 will survive shipping. Bitmain needs to fix the S2!

I'm in for two of the batch 4 units... I'm hoping/praying/wishing for early shipment by Bitmain (remember the good old days?)
This is a little more pricey than the S1 solution, but the reduced equipment footprint and reduced power requirements were enough to sway me in my purchasing decision.
May 8th seems like an eternity from now, and the new S1 price looks good but May 4th is 1/2 of an eternity (and I just bought 18 of the S1's at .6something)
For current holders of the S2, how many PCI-e 6 or 8 pin connectors are required if a power supply change out is needed?

But I think this should be compatible to Antminer S1, too. Let's see the example of why 0780 and 4F81 are 400MHz. HEX BINARY 15/BS M N OD 0780 0000 0111 1000 0000 00 00 0111 1 = 15 000 00 = 0 00 = 0 which NO=1 4F81 0100 1111 1000 0001 01 00 1111 1 = 31 000 00 = 0 01 = 1 which NO=2 5F82 0101 1111 1000 0010 01 01 1111 1 = 63 000 00 = 0 10 = 2 which NO=4 Fout = 25 * (M+1) / ((N+1)*NO) Fout(0780) = 25 * (15+1) / (1*1) = (25*16)/1 = 400 MHz Fout(4F81) = 25 * (31+1) / (1*2) = (25*32)/2 = 400 MHz Fout(5F82) = 25 * (63+1) / (1*4) = (25*64)/4 = 400 MHz Actually, 5F82 is also 400 MHz, but due to the instruction below 500 <= Fout * NO <=1000 Fout(5F82) = 400MHz, therefore, Fout*4 = 1600 and over 1000. So I think I should not config 5F82 for 400MHz, according to this manual. I don't say that it does not work (I tried it before understanding the HEX, it worked) but you have also another 2 freq_values which give you the same MHz and get along with the instruction in the manual. A little bit too long, anyway, I hope you enjoy my lecture, lol. Any questions are welcome.

(212.5 is 8.5% higher than the stock speed) tips accepted at 1LQZnkJuUbdeVdxGjR27zkNJWSW4FSLBhhnewly added: 6206 = 215.625MHz for some reason my system was a bit unstable at 218.75MHz. it had ~2.02% hw errors, but something was causing either the miner or the psu to switch off and need a reboot. (the PSU is a modified DPS2000 so it should be plenty powerful, but the cooling fan i stuck to it might not have been sufficient) 212.5MHz gives ~0.75% errors, so hopefully the middle-step at 215.6 will be around 1.1% errors and more stable.

If they can get them to customers without surgery involved in bringing them back up, I would bite. Until then, no dice. I got this in email from them by email: Me: Hi guys, I would like to check if the S2 packing has changed in any way to protect the blades more during shipping? Mine had a few blades dislodged and the host card, I managed to take it all apart and put it all back together again and its working but it seems I was lucky. Have you made any changes to how you pack and ship these to minimize the risk?
Bitmain: Hi, new strong casing, adjust the inter structure. it will be much better than early ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Best Regards BITMAIN

I don't think they do. no markings on the case, and nothing on the control board or hashing boards. Its unlikely anything is printed on the backplane either

Yeah, I have 10x coupons, so I'd sell them for like .1 a piece.
That said, I think I am going to wait a couple days. Bitcoin looks like its in a little uptrend, and I rather purchase it for 4.x BTC than 5.x btc. The difference might not be much in $, but I count my ROI in BTC.

Freq 175 I am going to post a thread in support. Asking for people to fill in the gaps [/quote] not much reason for such a range, since most of it is a mixture of hand calculations and a logic puzzle (last digit as '2' means twice half the frequancy as if using '1' and 4x as using '0') the ranges to focus on are: S1: 300-400MHz S2: 196-225MHz if you want a frequency outside that range you basically need to do the calculation with the end-frequency in mind. If you have a U1 it makes an excellent test-bench since it runs at a very similar voltage and frequency range as the S2.

I got my miner today and except 3 free spinning screws that I had to break everything inside was in perfect shape. I might know why too. See pictures below. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FEbw88N5.jpg&t=665&c=BYCdzhriwbUHTQ) This rubber padding might have something to do with my miner coming in 1 piece. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2Fpkp32DG.jpg&t=665&c=2sEtnn39kOx5EQ)

I don't mind building also saves time at Bitmain end. Could this be a possible option on the website ? would any other users agree ? Not sure if Bitmain would take a group of concerns on board rather than just a few users so should take a count or a vote ? At the end of the day it saves them hassle with RMA and pissed off customer if they just ship it how the customer asks.

Am I supposed to take out this foam? Is it possibly going to catch fire if I don't?
P.S. Nothing's perfect, I got an Australian cord. Where would I find a heavy cord to run this thing?
