ANTMINER S3+ Discussion and Support Thread

[hurricandave]

what is the recommended PSU for a S3 ?

can i buy 1 PSU 1000 watts and connect 2 S3 together?

I just started S3 mining and went though similar PSU choice issues, in the end i went with 1:1      1 psu per 1 S3.

To give me some flexibility I went with a FSP Raider 750 Watt 80 plus Silver PSU, it has 4 6/8 pin pcie connectors so I can fill all the S3 power connectors,
apparently this allows you to overclock and keeps the unit slightly cooler per given freq.

Secondly, it has a common 12 V rail giving 60 amps which is more than enough for an S3 and allows the PSU to run at around 50% capacity which has an efficiency over 90%.

One thing I have noticed with some Gold modular psu's is they have multiple 12 V rails and may add up to 700-800 watts but only deliver 18 amps (per rail),
 if you power you S3 with one connector per side from a rail like this you are going to have trouble as an S3 needs 24-30 amps depending on who you read.

With lots of PSU's it does chew up more space and power points but you don't have a single point of failure and your not running your PSU at 90-100 % capacity.

Good luck with your PSU hunting.

Will this PSU be able to handle 2 S3+ ?

Here is a link to a great guide for information about potential PSU's https://bitcointalk.org/index.php?topic=486121.0

Anyone is paying attention to unknown IPs by the antminer in addition to IP of pools setup on the miner.
I am not sure if this is related to this firmware upgrade but in my case there are one or two unknown ips connected at times that I cannot figure out.

its been said before the unknown ips is the way cgminer does the pool dns. or something, i didnt understand it.. but its known and ok.

Sometimes I can't communicate with one of my S3+ either through a browser and the GUI or through SSH. Even though I can't access it, it continues hashing according to the pool stats.

Has anyone seem this problem before?
Could it be a defective controller card?
It's still under warranty and I could try switching cards.
If so, will Bitmain send a new card or want the whole unit back?

I updated to the latest firmware on one of my S3's that is on leaserigs and now I can't lease it out.  Even after editing the files and allowing the api access and whatnot....all that happens is cgminer just restarts over and over again.  Went back to previous firmware (s3+ support) and all is fine. 

This is also the underperforming unit that barely holds 420ghs at stock speeds.

Anyone else experience this?

I'm getting the following error on the config page but the unit is hashing...

This page contains the following errors:
error on line 348 at column 34: EntityRef: expecting ';'
Below is a rendering of the page up to the first error.


Not sure what to make of it.

Get the latest firmware where this error was fixed, or (and I am assuming the error is on the Miner Configuration tab), login via SSH and enter:
sed -i 's/Save\&Apply/Save\&Apply/g' /usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua
That should fix it!

oops!  Wrong firmware downloaded!   

thx

please send me an email with ur order info, screenshots of miner status, sum up the issues you come across, i will handle with it.
Or u can contact Bitmainwarranty directly.

Doesn't make sense in a push/pull config to have one fan running at a different speed than the other.

It does have sense, but I'm not good enough in english to explain.
1/ Cold air and warm air don't use same space because of it's thermal expansion.
2/ the S3 is not full close, air can flow outside by many ways, not only by the pull fan.

Because of those two points, input air flow may be different from output air flow.

Positive air pressure inside the case reduces the rate at which dust accumulates on the internal components. Not prevent it, but slow it down and prevent other holes ( ie. the PCI-e connector thru hole) from allowing more dirt in.

true.

both valid points.  I usually build my computer rigs with positive pressure inside the case to help put the dust just at the points where the fan inputs in the case (have dust filters) to reduce the amount of dust buildup within the case.  This way the dust doesn't enter the case at cracks/vents.

I received my order of two antminers S3 yesterday. One of them just plain dead. This morning gave it a few rounds of on-off-on, the red LED then lit up, but nothing else. Frustrated, i pulled the power connector off one blade, and the bloody thing came to life!! I could configure it and all. Then I tried again with both blades connected, it went dead. So what is it? Faulty blades? Or controller issue? How do I claim warranty?

I'm in Malaysia.

Thanks!

Hi everyone,

I have one miner that has something rattling inside of it. Right from box open, it has been like that. Also, I cannot login into the 192.168.1.99 IP. The fans turn on when the power supply is connected, but absolutely no lights blink when I plug the ethernet cable from the miner to a router or computer. Ideas?

[MyRig]

Ouch, you may have a broken off parts from the hashing PCB may be...

If you could, could you unscrew the top case and see what is fallen off from the PCB?

or you can return the miner to the following address with Printed Original Purchase Confirmation Page with the shipping address portion included.  Also, a brief letter describing what's wrong with your miner.  The return address is

Hello Miners,
My HVAC guy is evaluating our mining warehouse cooling and he wanted to know what the BTU heat output is for a S3+. Does anyone know what the value is? Thanks.

Are you sure he's an "HVAC guy"?

1 watt is approximately 3.41214 BTU/h

1 S3 is approximately 1200 BTU/h

Thanks.
