Bitmain also offered me an S5, no strings attached. So here is my initial review.

Setup was easy. Plug it in and turn it on. DHCP grabs an IP address. My router identified it as "antMiner". Hit the IP with the browser and configure the web interface for pool credentials. Username and password to get into the web interface were root and root.

This new S5 is not quiet. The 120mm, 4200 rpm fan is loud. But sitting in a 40c room, the ASIC temps are reporting 62c, so it's looking nice and cool.

After running for an hour, it settled into:

Miner Speed: 1155 GH/s
BTCGuild Speed: 1145 GH/s
Power: 675 W (750 W Bronze PSU)

Power consumption is a little high due to the cheap Bronze PSU. Switching to my Platinum PSU should reach the advertised 590 W.

Initial opinion: Good efficiency, easy setup, meets advertised specs.

After some further testing I'll offer a comparison with the SP20.

Do you need to use all four PCIE cables or 2 for stock?

at >560W its absolutely neessary to use all 4 I think, or have a high-end PSU, as 280W over a single PCIe cable will burn up any 18awg wires, and likely even get 16awg wiring warm

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461
No longer a wannabe - now an ASIC owner!

When you say it is loud, is it louder than an S3 or quieter? Thanks for your quick review.

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.

Both miners have 4 power connectors. The SP20 can draw significantly more power per cable.

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

WOW! Loud.

Interesting.

Thanks for the information. Does that mean by comparison the SP20 is quieter?

Edit from other thread:

Okay just got back home from a party. I need to find a few other fans.

 at freq 250 I do 824 gh and 404 watts that comes to .49 watts per gh.

 I bounce to 416 watts which is .504  watts per gh this is good.

It will run too hot with my current fan setup if I go above freq 250. temps are 60c and 57 c

It is too  loud stock!  it runs hot at stock speed with stock fan. stock fan ramps to 3800 rpm and temps were over 60c for each board.



 if you want db's 75 plus it is a nasty  pitch.

my complaint is really simple here 2 silverstone 140's would allow it to run max speed and quiet. A no brainer 1 minute mod.  instead I will need to fuck around with it.

If noise does not matter run it stock.  It is louder then the s1 or the s3 it is as loud as the asic miner tube.  So far at 225 ,250, 275, 300  and stock 350 it scales close to .51 or .52 watts

per gh. I am looking at the stock fan and it is a bizarre fan.  It is 38 mm yet has 1 inch deep blades I have never seen a fan like this. I have to go back and correct part of the review.

3 shots of the  my wife will kill me sounding  stock fan.  it has 38mm depth with 25mm blades then 13mm focus grill. it was pushing 3800 rpm at freq 350 worse sound of any fan I ever use for a miner.

Both miners have 4 power connectors. The SP20 can draw significantly more power per cable.

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.

To an untrained ear I would say they are comparable. The S5 has a higher pitch.

yeah but the pitch is brutal on my ears.  

now when I underclocked to 250 the fan went to 3600rpm vs 3800 rpm.

maybe antminer can allow for lower fan speed if you clock to freq 250

I have  some more tests to do. full speed of freq 350

plus an over clock to  freq 375?

1 more fan due on the 31st

I have a 300 watt psu that allows for volts to be adjusted  to 10 volts.

I could do a board at freq 250 first at 12 volts then at 10 volts

compare to a board with a solid 12 volt atx eff of  90- 92

with careful testing and scaling the numbers I should be able to see how undervolting works.

still getting 1128 gh with freq 231
