4 cables at the kwatt meter = 552 watts  so 552 x .92 = 508 watts / 4 = 127 watts at the cable.

it must use 4 pcie cables 2 are not safe.

I am at freq 231.  I will test faster in 7 hours or so .  time to crash. I am tired.

Would I buy these yes , but I know I am changing out fans.

If I do buy some.

@ bick

is the sp20 not as loud.  if you down clock to better power numbers  like 1000 to  1300gh  it is better for sound.  I can spend $0 extra money  on a sp20.  but I can't see that with the s-5.   

Now all of mine are in a home that I share with the wife.  We will be able to sleep tonight with no noise issues since I swapped out the fans on the s-5.  I am running 7 underclocked sp20's no extra money for sound mods need . Just down clocking.

  For most of us that buy it the game with the s-5 will be what is the cheapest fan replacement that allows a good clock and decent sound.  I spent 27 for the two fans.  10 on ebay for the delta and 16 on amazon for the  silverstone.

no 75db at one meter 
my 2 fan swap dropped it to 60db with better pitch.

it is far louder then the s-3.

I am philipma1957.  I went to my other pc this only allows my backup account.

the s-3 is nothing compared to this.

if you want this in your house it will need fan mods.

In a shed or a barn  no big deal,

I boosted to freq 231  good solid numbers

552 watts for 1120 gh  that is better then .5 watt per gh

I don't know what these fans will allow safely but 1120 is good for now.

Phil is this your listing?

they say 2 is company 3 is a crowd.  But if we make the block for christmas it is good by me.

 i am on my other pc (philipma1957)


These really good numbers which improve when I open the garage door and drop the garage temp about 5-10 degrees F.

Also this is my 'high' meter 

the other one reads 938

the 775 should be devided by .9 = 850 watts maybe 875 watts

Wrong pc so I am using my second account.  I am philima1957

here is a screen shot of all 6 sp20's hash rates and settings.

 I am using the new firmware
I almost bricked one of the six units doing the firmware upgrade.
You need to use higher settings like .68 .68 .68 .68   then max at .685  fans at 50 or more.
then when you do the rebooting the machine will start.  after it reboots and starts you can lower the fans to 20 or 30 and lower your settings.  as you see all of my six are hashing at 1300 or lower. and fans are 20 or 30.  my attached garage is less noisy.  I can do more machines  my power is 6 x 700 = 4200 watts.  the garage has 5 circuits in it that means I can push to 7k watts safely. I think I could run 9 of these. Have to wait a bit to decide if  I order 3 more.

I am philipma1957 and this is my second account.  I am on the road  I sold 4 unit so far.

2 to a buyer on the west coast.
1 to a PA state buyer.--------------------this was shipped today
1 to a  TX state buyer.-------------------this was shipped today

I will get back  to my philipma1957 account in about 6 hours.

The west coast sale is mining as I type/

well if you want to under clock they are easy.

Overclock is harder a pair of cx750's will give you enough power to max your unit's hash power.

Fan at 90 is loud,  and you need a cold room.  you will use 1200-1300 watts to do 1650-1750

 Phil did you try for a lower number? I have a few evga 1300 g2 psu's   .  If you can run two sp20's on the 1300 I may buy 2.

I have 3 s-3 on my evga 1300 G2 they do 1470 gh at 1215 watts. Set to freq 243.75

If I can do 2 sp20's and get 2300 gh for 1215 watts that would be a huge improvement.

Do you have new photos Phil?

The price is very low too good to be true,

still looking pretty good:

yeah people do need it.  even if we make a comparison chart .

 based on prices 
based on flexibility

based on safety of the company. ie will they cut and run.

I played with cloud mining and for myself I only keep a pinky in  more often to make coin transfers and have a pool service. 

Well it is still negative as of today.


https://bitcoinwisdom.com/bitcoin/difficulty     =  (-0.99%)

Well it looks to be  at just under 2% with  5 1/2 hours to go

from your prediction's date  and time we have done very well. We just may break the bank with this  luck.
