Difficulty will rise, but maybe not as much as we fear. I think any rigs older than 1 year will soon have to shut down. You might see some S3 and S3+ stay in the game for a few more months- but a person will need free electricity to keep those running much longer.
Maybe I'm way off base tho.

Just saw this on my tracking from UPS "The receiver must pay the duties or taxes due on the package."
how much do I have to pay? Im in Oregon, generally never had to pay any duties or taxes.. but never had anything sent this value before

Mine was finally processed in California and is now heading to Toomim Bros in Washington.
I'm sending mine to Toomim Bros also so post your experiences when things get set up for you. I placed my order on 9/6 so nothing for me yet.
Well it arrived and they set it up fast and it's running right now reporting 4.6ish at Eligius.
I'm impressed with Toomim so far.
I had some SP30s being hosted by them and have nothing but good things to say about them. Really prompt response time to any questions/issues I had.
So it looks like the first day of sales for the first batch have arrived and the difficulty hasn't skyrocketed so I'm hopeful difficulty's not gonna be too crazy.. well until the SP50s are released..

Have you tried just using 2/3 pcie connectors on each board?
No; I don't see why anyone wouldn't spend $12 for adapters which allow them to not void the warranty on a $1800+ machine.
This being said the power draw is ~134 watts per pcie with 3 connected. Having ran a Bitfury full rig that drew ~240 watts per pcie I know an EVGA 1300 G2 can handle the ~201 watts per pcie the S7 hashboard pcie would draw with 2 connected.
Do I want to try this to potentially save $12 in adapters per S7? No; its not worth it to me.

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.

Do not think that voltage adjustment will be possible by any means except reducing the 12V supply. Looking forward to hearing results from the first person to try this?

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.

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?
Its not; the default freq for the S7 is 600

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
. 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 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).

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.

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?

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

You can software control the fan speed
Thank you Bitmain!

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