ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

[Prelude]

Pretty sure those of use who ordered S7s will never ROI. SP50s will destroy any chance we had with the massive difficulty increases they will cause.

i dunno, you gotta think people would be upgrading their large scale farms to sp50's which would take down existing gear.. diff will go up but it wont be massive.

unless of course said farms keep existing gear and just add on the sp50's.. or a plethora of new farm's come online

Hard to say. If someone or some group invested a lot of money to build 1+ MW infrastructures, they might want to take advantage of them by makxing them out with SP50s instead of just settling for the same speed at much lower electric costs. A lot of power companies will penalize such scenarios also by increasing the cost of power. They need to recoup their investment outside of your building.

probably, but it is one thing not to ROI to the tune of couple hundred and another to have the same with 25-30K.
I expect bitmain to go and price S7 super aggressively, if SPT will price theirs at or slighly above 25K.

I doubt it'll change the S7's price. Maybe if they were available to the public, but they're not. Even if they were, they are nowhere close to being in the same league. Spondoolies is Intel, Bitmain is Cyrix...

tech is good, but the direction is all wrong as far as bitcoin enthusiasts are concerned (bigger machines).
a manufacturer with 16nm tech at 0.1 J/GH and 10-12.5Th miner at a reasonable price will sell much more, of this I am certain.

Not a chance SP50 will be under 40k.  55k bulk pricing is optimistic.

numbers that you mention would make it irrelevant, despite an impressive efficiency.
you are saying it will be $0.5/GH? that would be worse than S5 and even Sp20.
check the profitability calculator.

Spondoolies isn't concerned about selling more. They're a self mining company now. They're likely going to sell just enough to large mines to recoup their development and manufacturing costs on the SP50 upfront to reduce their risk, and then close the doors to their customers to keep them from competing with Spondoolies/BTCS.

These are designed to be upgraded with new hash modules as released.  The PSUs and enclosure are extra.  Assume they cost 10k alone then do $/ GH calculations only for the hashboards.  SPT can always mine with these themselves, so don't expect competitive pricing.

I ordered a unit the first day with shipping to California via FedEx. It's already in Oakland (an hour away) and will be delivered by 10:30 AM PDT.

That's less than 4 hours from now!

It's also my wife's birthday, but she won't see this as a present

yeah, especially since you would have to blanket it with pillows or foam 

The S7 is here! Thank you FedEx!

Luckily it's destined for a data center, so we won't hear it.

[fullzero]

Just got my first S7

You can software control the fan speed 

Thank you Bitmain!

will you check if you can get better efficiency at lower settings, please?

[mindtrip]

My S7 Got delayed due to missing information I wont be getting it until tomorrow

[fullzero]

At freq 300 power and hash are almost exactly 1/2; so no apparent underclock gains. 

Not willing to ssh and change voltage settings yet.  These have a lot more hw errors than I expected, but within reason; 0.03 %

Trying to find the lowest fan speed that keeps temps below 60c.

What shipping company?  I'm kinda curious if the missing information ones are all same companies or different.

There have not been a ton but a few who have posted needing to contact shipper.

[fullzero]

I tested a bunch of different settings; I recommend:

Fan %    Freq     Watts     TH/s     Error %
 30         612      1237     4.85      0.025

Measured 76 dB at 30% fan speed; surprisingly quiet.
These run about 5C cooler than an S5+ 1/3 with the same power consumption.
This allows you to run the fan at a lower speed.

I used an EVGA 1300 G2 PSU so you should get slightly better w/GH with a server PSU.

0.255 w/GH with a Gold PSU

Could you double check the frequency? Looks like a possible typo?

[majestymage]

with spondoolies back in the game, i hope to see a price war again   . in my opinion the s-7 price was an insult. i've got free electricity and still did not like the numbers for roi.. this is a game changer for the best

cool...I will be running mine at a "fullzero"TM settings first.
did you split a couple of EVGA connectors or went with two/board?

[fullzero]

I have a lot of EVGA 1300 G2's so I swapped 1x single pcie for a branch pcie and used a $6 splitter on another of the single pcie.

I would recommend getting your splitters on amazon before they sell out.  You will need 2x of them in addition to the standard G2 cable set.

Yeah, but the products are ... slightly different

he he...already have four in anticipation...you've got to be prepared
there was also a good ebay seller with a bunch of evga 1300s for 129.99 OBO shipped. he might still have some.

I wouldn't get my hopes up on this. I expect Spondoolies will price their SP50 to look reasonable in terms a comparison to the S7. I don't think they will try and undercut the S7 hardly at all. Considering they have an efficiency advantage, they may well price above a commensurate number of S7's.

Unless and until we see a price and ship date, this is by no means "a game changer" (IMHO).
