well many of us have said it is not really a 1700 gh miner

what does power cost you? at 15 cents a k-watt   or more and there is no good choice

I also have some to give away.


  c-1
  s-3
  s-4

this is what I did 9 sp20E's   and 1 s-5 all underclocked a lot works best for me. and I have to tear the whole thing down in may as my rates go to summer price of 16 cents.

In the cold wither I pay 13 cents but I get a lot of heat which lowers my  13 cents to 10 cents.

So extra units with  underclock works best for me.

well little guys find it tough to wait for a block.
and if you moved up a bit to  1 or 2 th it was costly.
I think the euro miners are just quitting due to power cost.
My in house setup maxes at 4-6k in the winter and about 2 k in the summer.

Even with 9 sp20E's and 1 s-5 I can only run them under clocked. I can do 12th and that does not earn 1btc a week if a pool is a bit unlucky.

 power cost for me is 565 usd a month 4 coins = 1265 so I am clearing 700 a month if I get average luck.

Very tough to mine if your power is 15 cents  a kwatt or more.

I am sitting typing this and watching sons of anarchy on netflix.  the miner is on the truck.  If I am lucky the show ends in 90 minutes and the miner comes right after it.

3 or 4 ways can be used to predict the number.
 some sites use previous 1000+  blocks
some use previous 500 + blocks
some use every block since the last adjustment about 1950 as of now


http://www.bitcoincharts.com/ 

 as of this post this site says new diff will be 40,186,743,801   you can be safe to say 40.1 to 40.9 will be it next time.

yes the key is proper cold.    not too cold  -5 to +5c     or 23f to 40f   good psu  high fan and boom 1700gh is yours. 

I sent mmpool a trust rating this is the second one I sent.
I would mention to any bigger player when we hit a block some of us get .5 btc or more and mmpool has paid us everytime.
He should get some trusts from us.


https://bitcointalk.org/index.php?action=trust;u=308507

he has paid me more the 11btc since 9-11-2014 this shows last 5 payments

I would also bring up as a long time buyer-seller on paypal. (2003)   Many people get discounts from paypal.

I get a standing 2% minimum discount that does not affect the seller's bottom line.

So that 480 paypal price  now = 480 - 9.60  or 471.40.  Once I get my s-5 today I may do a paypal buy for 1 more. So if btc changes and shoots up I

paid in cash.

I also belong to square trade and as amazing as it sounds I most likely could get a 2 or 3 year warranty on this item for 30 or 40 usd more.

Not sure I want to do that but it is a possible option.

Well with a day to go we are near 4% so lets say we end at 40.7 diff.

Diff was 39.6 on Nov 5th  How many of us would think that from Nov 5th to Jan 12th  diff would go from 39.6 to 40.7.

I use Jan 12th Since diff will be the same from Dec 30th to Jan 12th.  This would be a 68 day time period in which we have had an increas off about

2.77 %.


 So Jan 12 to March 9 is 68 days.  and 40.7 x 1.0277 = diff at 41.8 up to march 9th.  I don't think so but it would make for a very interesting winter.

 I wish they would have listed it as 1450 stock and overclock to 1550-1700.

I see the two of them   head and shoulders above  them all the other builders.

he quoted my post in which I refer to his server runs this pool.

Frankly I don't know if he is just kidding.

thank you I will send a trust rating later.

Space saver for review

  here it is mining  freq 300 downclock
vs 350 stock power used is 487 at kwatt meter
it is loud 67 db


now 487/944 at the meter is  .515 watts per gh

Space saver for review. note I saved all messages and posts here via pdf. so many comments made me decide to delete for the sake of being neat.

Unboxing

box is shorter then s-3  as it comes with 1 fan



same type of foam with a bubble wrap bag

It is here!!  It works !! yeah

It auto seeks an empty ip address just like the sp20.

IT IS TOO LOUD WITH STOCK FAN AND STOCK FREQ OF 350

If you run stock fan at stock freq it is over 75db and is a nasty sounding 75db.

So a sound proof room and ear plugs are needed. My ears rang from the sound after I turned off the miner at stock speeds and using stock fan. (the fan is pictured here)

https://bitcointalk.org/index.php?topic=907219.msg9980310#msg9980310

if your s-5 comes with this fan you will almost certainly want to remove it and find a better fan or two fans.

That said I like other parts of the miner


Well with more test and going to freq 356 I get  1197 gh at 588 watts = .49 watts per gh   this is making the s-5 look a lot better.

I will keep the miner at freq 356 for 4 hours to see if it is stable at 1197gh/588 watts and very few hw's

This may make me think it is better then the sp20 if it continues to scale well as I crank up freq.

1) I got it to do 1156gh at stock speed---freq 350
2) uses 581 watts  at stock speed ------freq 350
3) that is .502 watts per gh
4) auto seeks an ip so if you have a 192.168.x.xxx router it should find an address easy
5) once fan modded sound is okay at freq 350
6) temps are 64 and 58 c  I think this is okay my room temp is 28c
7) gui has huge choice of freq from 100 to 500 in steps of 6.25 or 16 per every 100 total of 64 in all
8 ) new miner interface that allows you to see all your miners  use miner config then miner link

So that is 8 good things.

The bad

1) loud loud loud and since I am 57 higher pitched sound is nastier then lower so the stock fan  running at 3600 or 3800 rpm  hurt my ears.
2) it is an s-1 not an s-3 case.  
3) the black sides are plastic
4) no top or bottom
5) stacking is not easy due to plastic sides
6) my s-5 does not like to do more then 1200gh others have had the s-5 do 1300gh------- this may be the fan mod


Would I buy this at 455 for 1 shipped to my home over a sp20e for 500 shipped to my home
some will say use 2  not 1 miner to price compare
2 s-5's to usa NJ with shipping = 899
2 sp20's to usa NJ with shipping = 1000

well I need to add 54 for new fans so  899 + 54 = 953 s-5 vs 1000 sp20  at this price point the sp20 wins
if I make a big set up 10 or more in my house the sp20 wins due to ease to stack.
some people have setups of long none stacked miners  then it is a tie sp20e vs s-5

If I paid 800 for 2 s-5's shipped to my home and did a fan fix for 54 bucks I would be at 854 usd vs 1000 usd.  for a small setup I would say the s-5 is better in this case.


These are very close to the sp20 if they cost a little less and if you add a fan mod.

These are very close to the sp20 if you are able to manage sound in an isolated area.

These are very close to the sp20 if you want under 5  or if you do not need to stack them.

These would best the sp20 for value if the price drops more say 2 for 800 shipped to the usa vs 2 for 900 as they are now.

More tests later today.

I was offered to do this review with a free s-5 from bitmaintech warranty  at zero cost to me. Which was nice of them>  
They gave me no rules to follow they did not ask for a gentle review or please ignore problems.

But here is the deal I set a few standards for me.
 1)Try to be honest and fair.
 2) Ask myself this question   would I want to buy or sell to a person exactly like me?

http://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback2&userid=philipma1957

  my 11 year ebay feedback long before bitcoin was around

https://bitcointalk.org/index.php?action=trust;u=64507  

my trust on this site.

I did a review on   Spondoolies sp20E  it was fair and honest and I still add info to it.-----In that case I did not get it for free.

My goal is do a good honest review on this thread.

pull and while it is quiet it is not quite correct. 

 next will be push- pull

yeah this has it quieter and at 1158.

 the gap issue can be fixed by a piece of felt.

I think if I find a correct push fan maybe this one

http://www.amazon.com/Bearing-NF-F12-iPPC-2000-PWM/dp/B00KFCR5BA/ref=sr_1_7?ie=UTF8&qid=1419811286&sr=8-7&keywords=noctua+120+fan

I could do 1400 pretty quiet. this is not a big issue for me  but I love to tinker around.

I had these in the house----------after I put that felt on temps dropped on the 2 high ones from 115 to 110



closed two gaps one on each side


db is 60 but there is a lot of ambient noise the room is 52db due to all the fans in the garage.
