yeah no question I trust bitmaintech more then I trust jack and co.  but  I may have to buy from him.  I will sit  out for a bit.

I don't want anymore s-1's and 1909 usd is steep for 1th .

it  is close to the summer so low  amounts gear In my garage is fine. Hosting makes  more sense for me.

okay  I am at your website   ..   would order 1 of these  and let you host. I don't see a hosting option.  and I don't see when you start hashing if I let you host.

  I have to side with you.

 Also right now asicminer new gen gear is selling at 1170 usd for 800gh   

    so do I want to spend   2309 usd here (well 1909 usd after coupon)  and get a 1000 gh unit or do I want to spend 1170 usd and get an 800 gh unit.

   I have to add a psu. I have one.

I have to add a rasp Pi  so  for 1230 usd I get  800gh vs   1909 for 1000gh   

 This is very simple if the new asic miner 800 gh machine is good these s-2's are very overpriced.

you are apply wrong mathematical techniques  for your calculations  as many people do not understand all the variables involved.

BTC roi has no meaning if you purchased the btc with fiat.  the fiat price has the meaning.

 ____________________________________________________________________________
Also   who cares if you do a btc roi  
 
 in this case.  I buy today  at .419btc  use a coupon pay .369 btc.

 I buy the btc from an exchange today  at 585 usd.

 My fiat cost was  .369 btc x 585 usd = 215.86 usd.

  I setup a dedicated account at btcguild.  all btc and nmc goes to it…….  

BTC crashes drops to 100 usd.  difficulty drops like a mother fucker.  
when all is done my machine mines 3 btc and costs me 1btc in power. net of 2btc

so I kicked ass in btc roi I turn .369 btc into 2 btc .

 I whaled   but wait my fiat  was  215.86 usd my fiat now is 200 usd
_____________________________________________________________________________
think this can't happen it can  ..

if btc price drops a lot big time minign will stop and diff will drop.

  So do not lock yourself into btc roi.  your calculations need to take a lot into account.

1)btc roi

2)fiat roi

3)heating bill reduced  if you use a space heater in the winter.  you can turn on an s-1 instead.  

4)So s-1's can be stored if they do not make any money in the months of August, Sept.  then in OCT turned back on.

5)Undervolt/underclock makes extra money

6)  rising btc price allows  for power to be paid off and sometimes the price rises way faster then difficulty.

7) using an s-1 in a space with 'free' power  Or in my case  I can use 800 watts and pay for only 200 watts.

  So an s-1 cost me  only 4 cents a kwatt.

yeah I ordered  two blades from them and 20-30 5 chip units from them.


The first blade came on sat the 17th  of may   it runs wrong.  1 part does 2.3-2.6mh  no issues or worries.

 the other part does 1.4-1.7mh  I know he is busy but I hope to hear from him on  a credit  for this .  maybe 20%-25%  or around 200 usd store credit.

 this is the problem

I tested high end seasonic  psu with good plugs  switch the power switched the  mining pools and the blade side that powers the fan runs short .

With a store credit I can just order other gear.  I could order 2 or 3   five chip units from him   I am short about 1.2mh 

 3 of these  fixes everything I hope he reads this soon.




  A second blade is on the way I hope it works better.

looks to be all fixed thanks


you gave me

only  a user  

 not a pass

  and now locked out  without any warnings about trying the wrong password.


please recall my post from above

https://bitcointalk.org/index.php?topic=576844.msg6909833#msg6909833


let me know when you fix everything

I think you should see  if this thread sends at least 1 miner out that works.  If they deliver as promised the deal is good.

In fact I may buy 1 hosted myself.

I will contact zoomhash  thanks.

okay I will send in my fee .  I will send an email to ask you what the fee should be.

 It was 225 reduced to 220.  Due to some down time that happened to all of us.

 My miner has had a lot of issues since then and as of now it is fully down 0 hash.

1) If you could pm me what my usd fee should be since I have had more down time then the other miners I will pay you the fee.

2) If you could get my machine back up from 0 to 1000 please do so.


Thanks,

 Philipma1957


I am sending you 200 USD     we can figure out what the exact amount should be later.

here is the transaction


https://blockchain.info/tx/e8ba99f0aefc9b6764d9f5d15be6278ad7268d097fed1588873c0fbb2c6092ed

it is .348 btc  the rate on btc-e was 574.043   

let me know when you can fix the miner as it is at 0 hash.

enermax sells the exact cables on their website.

I seem to be getting a better result with freq 700 and running ½ on wemineltc and one half on cex.io


this way I AM GETTING  1.8mh and 2.4mh  still too low    but closer to normal also dropped watts to 75  vs 91 when the two were at freq 850


 at 75 watts for 4.2mh  i am pretty happy.  I will post on this in the morning as I am tired tonight.




to mods if this should be an edit to above post please merge.  it is a different day but not 24 hours.   thanks phil

so   what does a pair of s-1's clocked to 393 freq  hashing at 400gh pull on a k-watt meter?    120 volt measurement please...  do you get 800 watts or do you get more like 840?

I ask because   3 of the above    could run 6 s-1's         at 393 freq.   with wires   you would be talking 250 usd.   


 now I can get  2 evga 1300 watt super nova 2  Atx psus.    they will run the six at 393 hash at 1200gh  and pull   2430 watts. all on 120 volts.


but on a best price offer 2 of these are 320   Newegg just had a special on them.     

comes to 70 usd more.  the evga would be better only if    the hp's pull a lot more power.     the 320 price for 2 is hard to get more often the price is 340 for 2      even 380 for 2.

   to make up 70 in price  if the hp's pull 2550 watts vs 2430 watts .  that is 3 kwatts a day.  or about 40 50 cents.     so in 140 days the evga would be better.    but that is only if the 3 hp's pull 2550 watts.  I would like to see one with a kwatt meter.


I owned one of the 750 watt dells I had the lessor model it used 460 watts to run 1 ant at 393 freq.  due to this I decided to buy a lot of evga's

  but 460 x 6 = 2760 watts and you could run only 1.5 ants on a dell at 393 freq so I would  have needed 4 dells at 75 bucks or 300 up front.  to burn close to 2750 watts.

  I got 2 evga's and burn 2430 watts .  I paid 340 for the two at www.raktuten.com   my point is these may work better if you want to run six s-1s then the evga's

yeah I see why you ask you are around 60 posts.  if you leave and go to up/down today and do 60 posts  with them it would be better then staying here and doing a few more posts.  I am at 300 plus so i am staying on.

price is high  3700 gets me 30mh

I can get grid seed blades at 700 each using a cc. so I have a safe purchase of tested gear 5 cost me 3500 and I am at 26mh.


your deal puts me at full risk of no delivery.
your deal puts me at full risk of poor rma support

I just ordered a second blade will stick with them.

so this cost 12000 usd.  It hashes at 88mh  and uses 750 watts to do that.


a blade is 750 usd .       It hashes at 5mh  and uses 90 watts to do that.


so 16x the price

about 17/18 x the hash



and 8.5 x the power


not bad could work.

here is one photo  4 resistors on each side 8 per miner.

I can't tell you what fan to buy   because I do not know what fan you have.  

  your fan may move  up to 150cfm

  so any fan that can not be close to your fans speed will kill the machine. or at least make it shut down due to overheating.

here is a long list of fans all 140mm most are variable speed only a few move more then 100cfm

try to pick one of the ones with hi air movement.

thank you.  that would be nice. 

If you live close to New Jersey send me a pm.

  one blade runs low 1.7mh the other runs at 2.5mhz


I have used various psu's

I know it is not a lack of power

I use cpuminer freq 850 or freq 800   both show the one blade lower then the other.

Seems like some asics are not firing on the one blade.

does this mean rma?   should I do other mining software.

same issue occurs at wemineltc.com
