root/admin, its a beaglebone like the S2/S4

Yup, that does it.

I went to change the password to the webgui and got an invalid password (root/root which let me in).

I cannot login via SSH?  Am I missing something different on the S5s?

Yeah, I can't ssh in with root/root either.

Can anyone confirm the 0.2J/GH mining efficiency @ 9 volts made by Bitmain ?
I can give you DC efficiency numbers, I have a nice 0-16C, 0-50A linear supply. It would be wildly inefficient compared to an ATX supply though, so for at the wall numbers you'd have to go based on your PSU efficiency.

Bitmain's not shipping my units until the 4th though.

I can't even change the webgui password which was even weirder lol!

I'm happy with it at 400M. Any higher starts getting hardware errors which doesn't improve performance.

i dont get much HW errors, but hashrate seems to peak at 412MHz, at 425MHz its back down around the same speeds as at 400MHz
Can you try it at elevated voltage and see what happens?

not sure how to easily do this without a PSU capable of 13V at >60A, or even colder intake or higher airflow. temps are 55/53C with the back end of the heatsink reading about 33C where it contacts the PCB. using a cheap infrared thermometer, readings on the PCB range from 45-65C

I thinking he may be suggesting an adjustment in the software setting voltage (ie, as in the advanced settings on the S3+'s new firmware), I don't think the S5 has that option.
No, I was suggesting upping the actual voltage. Klondike uses some server PSUs and many of them can trim the output voltage a bit.
I have a few big adjustable supplies, but there's probably some leeway there for adjustment.

I was actually blowing off my deck today and wondering what -20C air fed through a gas powered leaf blower would do. Smiley

Ive generally moved away from server gear, though you are probably right that some of the server supplies i have lying around can feed a bit higher if you throw a resister on the feedback pins. not a high priority though, as im aiming to get it as quiet as possible without needing subzero intake or having boards go past 65C

Here's where I'm at with the 400 setting after 13min. Temp has been holding steady, but unit is in a room with the window partially open and 24F outside. Smiley  Don't want to push further today as I am getting ready to leave the office.


Elapsed   GH/S(5s)   GH/S(avg)   
13m52s
                1,490.62    1,368.15

these setting are almost like my SP20 in power, hash and temp. Care to report noise vs SP20?
Are you doing it on 750W bronze or higher wattage bronze?

Noise is comparable to SP20 (both systems all stock hardware).

So far all my testing of this S5 is with the same 750W bronze PSU. Only 1 change - adjusting clock speed in the web UI dropdown menu. The dropdown lists speeds up to 500M, but I really don't expect it'll go that high. That would be over 1.6 TH/s!

Once I find the limits of this configuration, I'll try a platinum PSU to see if there's any more headroom for overclocking.

i topped out at 356 using the silverstone fans. i hated the sound the stock fan makes

Overclocked to 400 MHz and still stable:

Ambient: 40c
ASIC temp: 69c
Board temp: 75c
Performance: 1320 GH/s
Power: 775 W
Efficiency: .59 J/GH (low efficiency Bronze PSU)

Over 1.3 TH/s easily achieved!

Bitcoin mining will come with noise hazard and heat!!!  for commercial mining operations you'll need the ear muff, no matter you use S5 or SP20.


I think this is where I take both you and SP-T to task for implying the S5 and SP20 are 'home' miners.  I unconditionally agree regarding commercial operations in data centers, server rooms, garages, etc.  But 'home' miners are in the home.  At stock settings, I believe neither of these would fit that category very well.

as part of my thanks for a demo unit i advised bitmain several things to make this a "home miner" (as it is the S5 is excellent for large deployment i think). I suggested a S5-silent model that costs $20 more and includes:
1) top and bottom shrouds made with the same light durable plastic as the sides. nothing fancy or bolted down zealously.
2) a second fan, OR adjusting the temperature monitoring and PWM control to keep the fan speeds down (running at 3000RPM for 40C is silly, 2000RPM and 50C would be more like an S3)
3) default speed of 325MHz. a few percent cooler/slower/quieter and easily ovewrclocked at the expense of noise

Agreed, looks like 311MHz default is more probable according to someone else's testing for a lower noise mode.  I would suggest instead of a silent version, just adding a button that would allow a silent mode so you can instantly up it if you're not in the room/area.  Also, simple request to move the network port a few mm higher as to allow easy use of the Silverstone 140mm fan in front.
