-1.2 = philipma1957  first pick if it wins i will roll it back in.

The corsair hx1000i is costly 170 to 200 for 1 unit  and  1 wont have enough power for the avalon6 or the antminer s-7

server psu's here with the fans recommended are far quieter then the s-7.

So a quiet expensive atx psu to run the s-7 does not make a lot of sense. you would spend about  3 x 180 to get 3  hx1000i's

they would run 2 s-7's  

the dual 2000/4000 would be able to run 3 s-7's  and cost less.


in both cases the s-7's would be louder then the psu's

but if you want to run an atx with the avalon6 try the evga 1300 g2

it has power enough to run an avalon6 and is pretty quiet.

I am not anti atx but they are not so good for the newer power hungry asic machines.

I like you was getting 74 to 77 with the oem sdcard in the older model rasp pi.

Kipper01 told me he was coing to try the rasp pi model 2 and load the image from the website.  it does not work on the older rasp pi's

I asked him to mail me a good mini sdcard for the rasp pi model 2  I tested it at  freq 500 and fan 20  and when the unit would get to temp of 70 fans ramp and cool back down. to 67 68.

Since I burned 1 hash board with  the 75-77 internals I prefer the 68-70 internals.

I since discovered if  set at 42% my temps stay flat at 65-66  and I  never ramp up the fans are steady at

I think the mini sdcard for the new rasp pi  adjusts fan speed so you stay under 70f.  So far I can not find an other difference from the older rasp pi

I have 155 in 22 hours

we should be 132 in 22 hours

so I get 170 give or take 3 blocks.

170/144 = 1.18  x 859 =  1013 ph   last adjustment we did an average of 970ph four days in a row.

So while we are ahead of the 859 ph from last difficulty.  we are  also doing our first 1000ph+ day

not sure reversing is a good idea.  my burnt cap was as far as it could be from the fan.

So it was near the intake and the cooler air. it still popped. ,but  here is something I do think you are doing right the 38% fan setting is better then letting the ramp up and down.
the orginal rasp pi card set temps to 75 the newer cards set temp to 68-70  so if 38% keeps you steady at 70 I think that is best.

you don't need that pdu   it has 14 plugs  and costs an arm and a leg.

 you want this  for 30 amp breaker

L6 30r

http://www.ebay.com/itm/Leviton-Nema-L6-30-Locking-Receptacle-30-Amp-250-Volt-/321924264154?


and this for your pdu

http://www.ebay.com/itm/Pulizzi-Eaton-Powerware-ePDU-T982F3-Series-Monitored-PDU-T982F3-F-SL-109-240V-/321000822839?

this is a 200 dollar pdu new it is fused and the plug will match the  receptacle above.

it can run 4 s-7's  2 on each fuse.

the 30 amp 240 volt breaker can handle 5800 watts safely

you can do 4 antminer psu's since you will be drawing about 1400 watts on each one.

sound level in my basement/den/HT running 2 ½ avalon6's  using the dual 2000/4000 watts  psu with breakout boards




units are in the garage



room for three more units




i turned the 2980 on and the noise level in my den is 38db.

I bumped thread with my secondary account. judypug1956


I just got off the phone with Yan.

He will provide me with tracking this evening.

He is aware of our payments made for the 18 units total.

he said these should do 3600gh to  3700 gh at .3 watts per gh standard voltage.

So for those of you with an evga 1300 g2  these should be good to go.

now I have an interesting sidebar piece of info.

Kipper01  was nice enough to burn a mini sdcard that would work in the rasp pi model 2  the newest model.

I have been running my 2 ½ avalon 6's and  the fans and temps have been reworked with this  card.

@d57heinz

Sure you can ask.  

I will tell you a full breakdown for the last  year I received  from bitmain
1 s-5 for free from bitmain I wrote a review on it in Dec of 2014 and part of Jan 2015.

I will even tel you what Avalon gave me for the thread on Avalon 4.1 I wrote a long interview on it around dec 2014 - jan 2014.

They supplied me with a free 4.1 and 1 discounted 4.1


And for the massive sp20 thread I wrote on my own I got nothing.  But once people responded to it well I got 3 sp20s for the price of 2.

All in all I believe I have been given about 4k in gear over the last 3 years.

I most likely earned about 7btc for posting since 2014.
To be fair about posts I made about 300 posts a month from Aug 2012 to April 2014. No signature fees

Since then I make about 500 posts a month.  with  signature fees

I have given back more then 1 btc on my diff thread.
I have given back more then 1 btc of free hash on my compac stick club.
I have given away 4 compac sticks for contests.

ON the s-7  bitmain owes me money and won't give it to me.
ON the Avalon6 I made 0 despite running 2 group buys.
In fact I am still waiting on the replacement board  that I paid 350 usd for.

Lastly in the server psu world  I got 3 servers last year to run reviews on

and currently I am doing a review thread  for finksy/j4bberwock   in which I spent about 600 usd out of my pocket returned 2 psus  for 700

and was given about 200 in gear from finsky/j4bberwock.

And if I was to be paid by the post I would be getting about 50% more then I do asking for the flat rate.

Trust me my motives on this site are very simple I make an effort to not go broke promoting BTC.

For me huge profits are not going to happen plain and simple.

lots of good points.

All my gear will be up for sale in april

I have to do this every year.

My power costs have a summer jump from about 9 cents (counting free heat)

 to 18 cents counting cooling in May.  So all my gear has to move in April.

The current diff is 120 based on 859ph of hash.

Last jump for a four day period we averaged 970ph.

So without any new stuff  we could move from 120 diff to 135 diff

All the yoyo moves have happened since bitfury put up the 40 megawatt plant.

 I suspect they are the biggest force in diff rise.

 avalon6's from blockC are about 1700 and a new amount came in yet to be sold and not all online

so 1700 x 3.3 th = 5.6 ph  if they sell all their other new shipment it will be about 7ph more that is only 12.6ph

s-7's sell and sell a lot  over 70ph based on bitmaintechs  btc addy's  but that is only 80ph

I think bitfury's plant is the driving force of growth.

sept 4   407 ph
jan 26   859 ph

so 452 ph added but more like 600ph

I believe bitfury runs 200 to 350 ph of this growth
I believe they see saw the hash due to the heat it makes

the tractor trailer sized container can handle 1.5 megawatts of power.
All the evidence I see point to them using these or a prototype of these.

So I created this thread on Jan 23rd  pool was at 12ph it is now at 15ph.

pool was at block 462 now at block 478

luck was 104 percent now at 105 percent.

So some people looked at data and switched here.  Good  it means some people can follow the math.

Here are the blocks made since this thread started.


478   395589----25.41921514
477   395570----25.55367288 ---------0.97288802 running fees total
476   395547----25.41797096 ---------1.39085898
475   395526----25.08867424 ---------1.47953322
474   395454----25.15668552 ---------1.63621842
473   395413----25.05953458 ---------1.69575300
472   395410----25.08223258 ---------1.77798558
471   395269----25.39623988 ---------2.17422546
470   395200----25.37273511 ---------2.54696057
469   395103----25.14451370 ---------2.69147427
468   394970----25.40052943 ---------3.09200370   
467   394915----25.21982920 ---------3.31183290
466   394899----25.42805777 ---------3.73989067
465   394867----25.12545889 ---------3.86534956
464   394856----25.05731858 ---------3.92266814
463   394817----25.14775137 ---------4.07041951


so these 16 blocks are 16 x 25 = 400 + 4.07041951 total =

404.07041951  kanos fee is .9%

so 404.07041951 x .991 =

 400.43378573441

if you use antpool  PPLNS   it would be 16 x 25 = 400

The antpool no fee is deceptive  as they do not give you the fees earned by the block.

If you used ant pool [PPS] it would be 16 x 25 = 400 x .975 = 390

So:

  kano.is          =  400.433785
antpool PPLNS =  400.000000
antpool PPS     =  390.000000

these do not account for luck  these are fee structure numbers

they favor kano

when blocks go from 25 to 12.5  the numbers will favor kano more.

Since the tx id block earnings  will rise  and the block rewards will ½ .

BOTTOM LINE TRULY FAVORS MINING WITH KANO.IS



ps: I get zero $ or BTC for this thread

rental  the best a stick has done for me is 2.15g

15ph is nice but I would love us to be 5% of the network.  So 859 x .05 =  42.95ph  we have some work to do.

careful rentals have been high.

 The easiest upgrade to this is  use an almost empty roll of bounty paper towels instead of the next to empty roll of Scott tp.

And saving 35 watts 24/7/365 adds up. 25 kwatts a month at 10 cents = 2.50 in 1 month and  30 bucks a year.

plus those freaking screaming fans have been halted.

I will revisit this mod as I have a real upgrade in mind. (fan speed controller} so that these do 3000 rpm not 3500 rpm


I also want to push the psu at closer to 2800 watts it would be nice  if this mod can do 2800 watts at 3000 rpm.

Still 2400 watts at 3500 rpm is okay.

tape air leaks



and 75 db screamers are now 53 db

oem fans use 60 watts to move 180cfm

these fans use 25  watts to move 156 cfm

The 2980's were tested at 2400 watts for 2 days  2 ½ avalon6's

take shape the slit on the side will be taped




those grills will protect you from the blades which will move at 3500 rpm  loud but not insane like the stock fans.


note the pcie to the fans is protected and on the other end the roll of tp blocks air so that all the air hits the psu




the back of the breakout board has live 12 volt power




this flap shields that back of the breakout board

roll of butcher twine



the fans and the fan filters



ypu only need 1 of the two parts the none filter part.  these are a perfect match same company





black pipe cleaners really work well



these labels face in

look at post above  now wait for it
here it is the tp roll



and here is the other end og the pcie cable




that string is butcher twine  as the finksy/j4bberwock board does not attach to the bigger vent holes in the 2980



zip ties work but I did not have any long thin ones the back of these boards have exposed 12 volt power so non conductive ties are needed.
