Can the fans be replaced with something quieter? I bought two of these and they are super loud.
BTW: I am we6jbo on here however I don't remember what email I used years ago.
I would wait to see if we get fan profiles via firmware first.

Ok I will wait then. I've also got this question. I'd like to use this miner part of the time. Does anyone know if it's safe to turn on and off the miner using the small button on the back next to the power supply? (By holding down the button for 3sec). I don't want to slowly wreck this machine but there's also no way that I can sleep with it on.
Thanks!

Anyone know what the max safe overclock gh/s is and the power consumption? Thanks btw great set up guide as always

Anyone know what the max safe overclock gh/s is and the power consumption? Thanks btw great set up guide as always PSU gets maxed out by about 2.3-2.4GHz. You may need lower if chips start dropping out.

You may need lower if chips start dropping out. Has anyone done a study to map out frequency to overall hashrate? And what voltage to use? Since they advertise up to 10% possible on some units, I think 218.75 is a good number to try, but what should the voltage be set to?

Hi guys, I have found a lot of people having problems with there AntMiner S4 and not getting proper hashing... When I first hooked up mine I was only getting 800ghs... This is how I fixed it. https://www.youtube.com/edit?o=U&video_id=bdhjjHDA_wk

As i see 1400 watt PSU is not completely enough for S4. 0.69x2000 = 1380W (PSU is on it's limit!) A higher watt PSU or 2 PSU will be better for safely working but it's an extra cost. What about unplugging the power cable of one module? (i think there are 4 modules and power sockets). Will it work with %75 efficiency (1.50 TH/s) or it will not work? Or is there a way to reduce power consumption and hashing by modifying voltage or frequency? Is there anyone have tried this?

Its more like 1300 1400W AT THE WALL, not pre PSU. The PSU is likely only using 1250W or so of its 1400W capacity.

Ok then stock PSU will be enough for the default core voltage and frequency values or a bit down clock rates.

Hi Dogie,
thanks for the guide ! In regards to the Power setup, as the s4 does not ship with a power cable they recommend "a line with no less than 16A " on their website. The normal 10A 250v cables seem to work perfectly. Is this safe?

If you're on 230V yes, if not, no.

My B2 S4 works perfectly running 7 x 24 for two weeks, but two days ago the hashing power goes from aprox. 2Ths to 0 without any reason. I'm able to access the miner, that shows the hashing downgrade. Soft re-start makes no difference and I need to manually restart it to get full hashing power again.
Do anyone else have the same issue? Any work around it?
Thanks!

Hey so I just got my S4 in the mail.
When I turn it on, it says the IP is 127.0.0.1.
How can I connect to my miner? When I try going to 192.168.1.99 nothing comes up.
Do I need to have it directly plugged into the router or can I plug it into a computer that is wirelessly connected to the internet.
Sorry for the questions but just trying to figure this thing out.
