call an electrical contractor get an estimate.

The shorter the line the less it costs.

Also a lot depends on your main box. 150 amps or 200 amps = okay

100 amps = no go.

people are aware of this.  

so if btc shows 1000 units sold tack on 10% or so for other sales and we are at 1100.

just a guess but it is more then 0%  so why not  not just pick 10%

and realize we are 1000 to 1100 units sold

Would be nice to get a few good coupons for batch 2.


 I ordered 2 on day one so 2 coupons for 200 each for batch 2 would be nice.

really hard to just quit.

I have 2 s-7's on order.  I justify that I have an idea to make the run at .18 watts a gh quietly and I owe the community to show the idea in a long detailed thread.

Along with the above I will do a very long and through review.  Sound meters.  Different fans. ways to reduce noise.


That said.  At best  it will be 72-77db  and nasty pitched when it arrives.

I think I can do 65db and better pitch sound with high hash say 4400-4800.

I know I can do  45db to 50db with downclock to 3000gh

I hope I can do   45db 3000gh  and .18 to .20 watts.  with downclock and voltage drops.

July 2016 is 10 months or 300 days away.  Making this the perfect time to expand.  Since you should roi in 250 days with this gear.

We may have 2 big jumps this one and the next or the one after that. Then we level off.

All the big guys will had filled their mines.  And lots of old gear will turn off.

the diff is going to be close to 57  next jump


I see 60 getting past and then like 50 was really tough to pass I think 70 will be hard to pass.

As always past history means nothing when picking the future.

you don't understand my goals.   

sound is my issue.  I have a 2.4 cent location  but I need quiet gear there.


which means fans need to be swapped.  power needs to be cut. I also need to find bottom voltage. For longer use.

The net is difficult to explain in detail as  people do not like to read long posts.

BTW if I am correct this machine can do 0.20 watts or maybe 0.18 watts  if so   then a 636 watt psu will allow  a down clock to 3000gh.

I will have a close to silent s-7 that is more efficient then any other piece of gear on the market.

At 2.4 cents and 0.18 watts  this gear will survive the ½ ing

people have clocked s-5's to use 0.3 watts vs 0.51 watts  see below

okay

you have nine blades each has  3 pcie cables


blade 1

blade 2

blade 3        this has a power issue   

blade 4

blade 5

blade 6

blade 7

blade 8

blade 9


so turn the machine off pull the 3 pcie cables out from the blade 3


start the machine that not that blade 3 should read  nothing since it has the plugs out.

if blade 7 reads nothing you started on the wrong side

turn the machine off  plug in the three and unplug counting from the other side.

then turn the machine on  now blade 3 should be blank.

all other blades should look great.

turn the machine off.   keep the 3 unplugged pcie cables off to the side.

unplug one of the blades next to the blade 3 


use those cables in blade 3


turn the machine on   blade 3 should be perfect since you know the cables worked in the blade right next to it.


if blade 3 still sucks   you need to contact bitcointech to get a new blade

if blade 3 works  the the problem is in the cables

 try looking at the 3 pulled cables again.

i think you have extra if you have 3 psu's swap in 3 extra cables.


Thats all I got.

is that all from the same miner?


you may be lucky and have a simple power issue.  loose cable etc.


So what do you use for the power supply?

board  3 or blade 3 appears to be  not getting enough power.

get an ip scanner now!

do you uses windows or mac.

you really need a scanner for mining  I have had more then 30  miners hooked up  ip scanners allow me to figure out issues  with them much faster.

 8 sucked  8.1 sucked never used them.

I used  w95 nothing for a while then    w7 w10

A photo or two on imgur works . Unless they are Google owned.

I try to use bing and yahoo when possible.

May just  be a hoax.  No unusual patterns in pools.  Plus  The report has been updated and called a hoax.

https://bitcoinwisdom.com/bitcoin/difficulty (+4.83%)  close to my current number

500 to go.  We may have a carry over.

Our max pick ends at 4.50%

I have found a 636 watt psu  88% efficient but costly at 128 usd.

I have 2 s-7's on order and I have one of these psu's on order


http://www.onlinecomponents.com/datasheet/hrp60012.aspx?p=37810156

model is Mean Well HRP-600-12 

adjusts 10.2 to 13.8  88% eff

I even found the absolutely best possible psu but it cost even more


http://www.onlinecomponents.com/mean-well-hlg600h12a.html?p=45585982


http://www.onlinecomponents.com/datasheet/hlg600h12a.aspx?p=45585982

HLG-600H-12A

note that A means it has a pot adjustment  10.2 to 12.6

this is 92% eff with no fan!  but it is 198 usd and is only 480watts

It does allow for a quieter miner but is too pricey.

With the cheap model HRP-600-12  I get up to 636 watts.

I will find a freq that allows me to run at 600 watts and 2400 gh.  say 150 vs 300

I will test it with the evga 1600 p2 making sure I am doing around 600 watts I will remove it

I will then use the meanwell  and once it fires up at freq 150 2400gh  600 watts 12 volts.

 I will back the pot down to 10.8  we should get a good watt drop off and the machine should run well.  maybe 500 watts for 2400 gh

I will then know if the s-7 has lower watt then rated.

Maybe
It
Will.

I am checking various pools in China.

I have been using a private address provided by mm pool op works fine
