Thanks Cyper

As i was reading through this topic, people were saying that sometimes you need to turn off and restore to defaults, to get the full speed, probably from main voltage spikes. I have relay board for the arduino, so i want to connect the two wires on C and NO. Is the reset button the same switch for restore to defaults ? And how about the power on/off switch?

Power on/off does what it says.

The reset button [use a paper clip or something similar] will reset to factory defaults.

I think what he was actually asking if it's possible to remote control the on/off button using some circuit board.. I think....

Cyper can you please tell me for the reset button connections are they easy accessible, is there a way to solder two wires to that connection? My miners are on the way and i have arduino board here and want to make remote program for remote restart to defaults and remote hard reset and so on...
thanks

ok but you dont need hardwired hardware, you can just a simple TCP ssh connection remotely and you will do everything. bu if you can trust s4 place owner like datacenter maybe you have like that Wink

( also add gps module for me

joke ofcourse, i can help you whatever you want. (reset button is bottom left side near the LCD panel, this microswitch 1 wire is interrupt to BBB(beagleboneblack) other is GND. simply you can use pc817 optocoupler for down logic level to gnd.)

Well I'm dumb. Maybe too much turkey.

Someone turned the dhcp server off. All is well.

i am from Turkiye (but we are not turkey) pure TURK. Wink

connect it your DHCP enabled network wait for a minute than you will see on LCD S4 s ip adress
then use your web browser configure static ip your desired and save.

I'm assuming he's already tried that.

I got 4 new S4s and I booted them up and the IP shown is 127.0.0.1.

Any idea on how I can connect into my S4s?

Is it connected to network? That is local host, making me think it is not connected to network.

Yeah it's connected, got blinks and everything.

Reset button, then if not reflash the SDs [image in post #2]. Its the simplest way to get them to wake up when you get stuck in 127.

Did Anyone heard beep sound from yours S4 at anytime (boot-working...)?

Hi guys,
After hard work at trying to understand how the antminers S4 fans works (40 hours of my time) , I have finally been able to change the S4 fan speed by changing software.

This allows to effectively decrease the noise from the s4 AND to decrease the power consumption by a maximum of 100 watts (expect 30-50 watts).
...

can i ask how to do that ?
i have a little linux knowledge and i dont know how to edit ELF file
did you do that simple changing the offset 1180 ? or decompile and compile again ??

I first tried to modify cgminer (modify it and cross compile it for arm) but that didn't work because it seems seems cgminer has no control on the fans at all. I then thought that it was in the bitmain_spi.ko binary because it it loaded and needed by cgminer.
I dissassembled it (with objdump) (no source available for this one even though I saw GPLv2 in the binary) and tried to understand the changePWM and adjust_PWM_from_temp functions. After rewriting theses functions to C, I understood that I could change a single value and affect the way the fan speed is calculated in changePWM. The dissassembler gives the address of each instruction so I replaced it by lower values with ghex, an hexadecimal editor for linux. And it worked.

What is the offset 1180 you are talking about ?
The problem I still have is I can't find how to go lower than 2640 or 2520 rpm.

good work maybe i can fix my voltage problem on the boot Sad

i like objdump.
i saw in your modified ko binary offset adress is 1180

thank you very much.

RMA time.

He had a dying board, we asked him to post additional info to see if we could get him up and running without an RMA. It wasn't possible, so I confirmed he needed to RMA. What are you talking about?

Look at the image again and search frequency 218,75M
Now do you understand what I'm talking about ?

For Dogie, regarding my issue,

I have power cycled, rebooted, checked connections, reset to defaults, reloaded firmware,, and still cant seem to get these chips to pop up,,

out of the 11 that we have this is the only issue.

we have 9 more on the way, should get them today!

Also I noticed people talking about pools,, we use miningrigrentals to rent our gear but when it isnt rented,, My favorite pool to use is Bitcoin Affiliate Network,

They have ports specifically for difficulty *2048* so if you choose the proper port for your miners you dont have to worry about the share Diff as it is locked in.

They also pay per share so your not waiting on the pool to find a block to get paid,, they pay every 2 hrs per share,, and they are paying 10% OVER as a bonus.

Like your set up on the racks you've chosen.

Now, you will need to think ahead to determine how you will get rid of all that heat as you add more of them.

Have a good day! Grin

Thank you. Yeah, I've got 2 x 2500 cfm fans coming. One in one out. I tried the aircon (12000btu) but it can't keep up. So I'll just have to rely on natural cooling. With the hot temp here in Singapore, they are running 56-63C depending on the time of day which is still ok.

The ear plugs are seriously good as I'm stuck in my small little home office with all the miners, a few pcs, laptops and a couple of NAS. I live in an apartment so no basement or attic to hide them miners and the wive refuses to let me put them anywhere else. LOL.

I PM'ed you to avoid complaints.

Hey guys,

I have a problem with one of my Ant S4's. This evening it looks like a board went out and it won't come back. I tried the following troubleshooting steps. The Chains do not show temp which is weird.

1.) Change Pools
2.) Reboot Unit
3.) Power Cycle Unit
4.) Upload the two new firmware in order from bitmain site.

What are the next steps?

Open up and inspect for damage. I'm not sure which board will be your board 3, might have to unplug one and test each time. Once you've found it and if it looks good, try swapping over PCI-E and data cables. You don't need to have all modules plugged in.

Its in a datacenter. Any chance of an RMA and just getting it swapped out?

You'll have to send a request to [email protected] for the RMA, was just wondering if we could get you up and running without downtime.
