Like other S4 owners, one of my PSUs blew shortly after the 90 day warranty. Bitmain's response? "find one from your local market".

It's astounding that Bitmain will only give a 90 day warranty on their PSU.

I was pretty sure I wouldn't be buying anymore Bitmain hardware. This sealed the decision.

Hi smit,

Have you made a version of the firmware posted by nicehash with the slow fan speed mod?

Also, would you be able to look into the problems with the Jan 29th frimware? In a nutshell, the voltage controls don't work, ie setting anything doesn't actually apply those voltages. Another new problem is that mining on p2pool is totally messed up at speeds of 225MHz or higher. It works perfectly up to 218.25MHz. This wasn't an issue with the Oct. 16th firmware, p2pool worked perfectly at all speeds.

Bitmain has acknowledged the issues, and is "working" on a fix. We all know how long that will take... Would be amazing if you were able to fix one or both of the problems!

(I know I could simply use Oct. 16th based firmware, but the Jan 29th firmware is better in every single way... Much more stable)

Hi, this is not so easy task for me since i don't have s4, i will see what i can do.

I'd be happy to test with you using one on my S4s!

I'd say fixing the voltage is the biggest priority. You can add me on skype if you'd like to work on it together. prelude514

If we can get this working I'll give you .1BTC.

Anyone else want to pitch in? I know most of you guys probably won't, but come on... If smit can do this you'll be using his firmware for sure to underclock and save money on power. Don't be greedy pricks! And don't expect bitmain to fix this anytime soon.

Hi,

If anyone is interested, here is updated firmware for AntMiner S4 with extranonce.subscribe support and fresh cgminer version:

AntMiner S4:
https://www.nicehash.com/download/AntMiner-S4-SD-firmware_cgminer_4.9.0_nicehash_and_normal_fan.tar.gz

Details explained here: https://www.nicehash.com/index.jsp?p=software#asic, firmware was prepared by smit1237 (thanks!).

Kind regards,
NiceHash.com

This is fantastic thank you. Just one thing on the website it notes

"Instructions how to replace stock AntMiner cgminer binary are included in the zip packages as README file."

I downloaded the Antminer S4 file you linked but there is no README file. I can run back through this post and learn but you should get that in there.

This is whole firmware for your miner, don't modify it, just load via web interface like regular bitmain update.

I try loading from the web interface and get this... tar: invalid magic tar: short read cp: can't stat '*': No such file or directory

Is this modded firmware based on the Oct. 16th or Jan. 29th release from bitmain?

Jan. 29th

Quote from: Prelude on March 27, 2015, 10:42:46 AM

Also, is there a version available with the fan speeds lowered?

Not sure, you should ask smit1237.

Thanks, going to give this a try since bitmain doesn't seem to be in a hurry to fix their broken firmware. Is this modded firmware based on the Oct. 16th or Jan. 29th release from bitmain? Also, is there a version available with the fan speeds lowered?

I have 2 S4's both running the same over-clock. One has its 3/4 boards running of the original PSU and the the last board is running of a corsair HX850w(80silver). Im also running some of the fans on that PSU. The second miner has its boards taken out of the case and placed on a custom cooling rig I have build,( nothing fancy just a lot of fans strapped to the boards) they are running 40 decibel, as I am waiting for the replacement fans for the case(3/4 were DOA when I got the miner). The second miner is running 1932GH/s with only 3/4 boards no dead chips max. 47 C. I am not going to risk overheating my 850W psu so not running the last board from the second miner. Going to get a bigger PSU. I have free electricity currently where I live so going to take advantage of that. Also the miners are sucking outside air of ~9C but my room still gets like ~15-20C. That's why they are so cool. I' m using the latest firmware update from Bitmain and smit's 4.9.0 cgminer.

What is the single board running off the corsair pulling at the wall? Wondering if I can run 2 overclocked boards off a single 750W server psu.

I don't have a watt meter for the PSU but I have run 2 boards on the 850Watt (80silver) PSU I have, on stock voltage/frequency (206.25Mhz and 0.725Volt) without any trouble. I think you need at least a 1000Watt PSU if you want to run 2 boards over-clocked. You may be able to run 2 boards stock at 750Watt ( gold 80) minimum but don't push it, you want to have 10-20% to spare if you going to use a second PSU. It depends on the efficiency of the PSU all ways have some room for wear, the efficiency will drop with time. Will get a watt meter soon.

Hi,

I have a S4 and by accident I have format the SD card.. Cry

Where can I find a image to restore my SD?
I cant find it here;
https://www.bitmaintech.com/support.htm?pid=00720140413044945482bs4xshkh072D

or should I download the "Initial Version." and just unpacked to SD?

My S4 Is running at 0.760V 256.25Mhz here is a test run I did. 2 chips cant handle the frequency but they work fine when running stock frequency and voltage. 0.760V might be a bit high for that frequency but it gets them chips stable. Also don' t mind the difficulty, I am renting it out at the moment and the renter has a crazy pool. Also running one of the fans on my own controller, testing my controller. Want to run all the fans on my own controller. Don' t like the noise.
The temps are steady and will hardly ever change more than a few degrees. I figure this is okay?

Your temps are great considering the overclock. What power supply are you using? Also, which combination of smit's firmware are you using?

Mean while, here is the fan spec for you.

Power consumption: 1600RPM 1.68W / 4000RPM 25.8W

How to get this 1600RPM (original fan) on S4? I never had lower than aprox. 2500RPM, even if I had in the room 0C and underclocked (and board temperatures were aprox. 30C)

You can build you own controller for almost nothing and connect the blue PWM wire from the fan to the controller. That way you can control it down to 1600RPM. I am currently testing my own controller. You can hook up a temperature sensor to the PWM controller.
