ANTMINER S4 Discussion and Support Thread

[mdude77]

For S4, if the miner powers up, the back light of the small LCD comes on but screen shows blank, highly likely it is the MicroSD card either got loose inside, or data on the microSD card got corrupted.

You will find the MicroSD card inside the case, behind the LCD panel and next to the PSU.  There is a Black Colored Beagle Bone Black and there is a little MicroSD card slot on it.  Lightly push the card and it will pop right out and push it back in.

Then please try to power it back on and see if it boots up.  If not, you may have to use this software to reimage (Write) the factory default data of S4.

That's exactly what I'm using.  Bitmain needs to do a little more quality control on the info they give out.

MY S4 has been in operation for almost two weeks.
Last night it shut off.
I left it unplugged for a bit and now when I plug the power in the fan in the Power supply turns very slowly by itself and when I press and hold the power button the red LED flashes and the yellow one under it stays on but nothing else, the fans never spin up.
It will stay this way as long as I leave it, I can press and hold the power button again and the LEDs will turn off.
Try to turn on again and same issue.

Seems like it is never booting, maybe control board?
Probably PS issue, but I did not want to go further and tempt warranty coverage before speaking to someone from here who knows more about the S4.

Two SP20s came in last night and were a dream to use, not near as noisy, and I am happy so far. I will be ordering more of these, but not more of the S4 at the price rate they have.

Reminds me I owe roadstress some BTC.

I can't find any type of support through the Bitmain website, no forum, nothing but a manual and firmware and the manual tells us nothing about the ATX PS LEDs. This is supposed to be a B2 and have a "good PS".

Antminer S4 90-day warranty is a big joke

<quoted>

...
Also regarding warranty I am pretty sure it applies from the time an item is RECEIVED...so if its never used once and lost in shipping for 3 months no warranty?? this is a joke
....

Common sense says so, but it's after shipping date

sorry

I am running 3 s4's since 3 weeks and have few doubts to be clarified by any experienced users. Our machines are hosted somewhere else.

In the beginning hashrate was very unstable and after upgrading to latest firmware, they became lil stable. I use p2pool.

-what does hard reset mean? In-detail please?

-1 of our miner has lower hash rates with 1 or 2 'x' asics failing always.After running it for sometime x starts appearing. Contacted bitmain and they said to test each blade and we did all troubleshooting stuff and they worked fine when connected to separate blades. Again after connecting all, 1 'x' appeared and hashrate is slow after 10hours compared to others.
For example on p2pool with default 200mhz,725v on p2pool with pseudo,actual difficulty set to /8192+8192, hash rates are as folllows after running them for 6days :
miner 1 : 1970gh
miner 2 : 1965gh
miner 3 : 1850gh ( which has asics failing issue)

All above stats are from antminer panel and p2pool graphs shows a different story. All 3miners work with same worker.
deadhashrate overall for 3 miners on pool is 270gh. shall i set difficulty to 4096 for a lower dead hash rate or is it something to do with pool?

- I am planning to overclock the frequency to 212.5mhz on 725voltage. Will that work or any consequences? I have seen people doing 225mhz with 725volt.

comments are appreciated. Thanks

Most Bitmain hardware since S1s do not function well "out of box" with p2pool.

You should be able just add "+2050" to your user names to take care of the low work size problem.

The other thing you can do to help is lower your queue size.  As far as I know the only way to do that is via SSH.  One way is:

/usr/bin/cgminer-api "setconfig|queue,0"

I think you may be able to change it in a config file as well... but I'm pretty sure, regardless how you do it, it'll get lost on the next power cycle or UI change. 

I'm currently using my S4 on p2pool locally, which makes it easier for me to set the queue size.  Once I move it to hosted I'm not sure what I'm going to do as I won't have SSH access.  I've discussed it with my host and they can set the queue size once a day.  I may end up just using something else besides p2pool.

Please try setting the pool side DIFF to 2048 or +2050

You can try connecting to BTCGUILD.COM and see if x goes away or hashrate goes up to where it should.

The hashrate you see on the control panel and the poolside may varies due to many different factors.  Our guarantee is the machine side hashing rate

Was, as in past tense, and not any more?  It's certainly not a Windows app.  The files in it are:

am335x-boneblack-bitmainer.dtb
initramfs.bin.SD

omap3-mkcard.sh

uEnv.txt
uImage.bin

There are no windows programs here.

The readme.txt says:

Code:

Operating in linux£º
1.Change to root mode using "su" cmd.
2.Insert SD reader with SD£¬linux mounts device automatically. Using "umount /dev/XXX" to umount device. XXX is device's name.
3.Using "fdisk ¨Clu" to check disk device in linux.Normal it is dev/sdb.
4.Copy omap3-mkcard.sh to linux system£¬add execute mode using "chmod +x omap3-mkcard.sh"£»"./omap3-mkcard.sh /dev/sdb" to part SD.

If your PSU is showing Yellow LED light, then the PSU is not functioning.  Please follow the RMA process in the PM.

I suggested +2050 because 2048 causes the lastest share size not to show.

Thank you!

The red light flashes and the yellow light is on solid.
The PS document with the manual shows this red as "protected mode"
Can you tell me what protected mode "in protection" means? It doesn't allow PSU output?

Do you need any information from the PSU? Shouldn't I isolate it to be confident it is at fault?

[MyRig]

if the PSU is showing the red LED, please contact the warranty service!!!

Need the original Bitmaintech.com purchase Confirmation Page

Thanks for the response, but for some reason our hosting guy suggested to put /8192+8192 in miner settings. Will change it to +2050 now.
The stats i posted above are from control panel.

About connecting to BTCGUILD, i will soon do it and let you know the results.

About frequency testing with normal running miner, changing it to 212.5mhz with default 725volt is showing 2100ghs avg but hw errors seem to be more but the % is negligible though. I doubt if the miners power consumption increases by changing the frequency but not the volts, any idea on this?

Changed the diff to 2050 and everything looks good for now and this also shows best share now. The only change i noticed is utitlity became 12+ whereas it used to be only 3+ in past. What does this mean actually?

Changed the frequency to default after few minutes on the miner which i was testing. (I was not messing with the miner which was problematic). I was just testing it to know the change in Ghs if any.
By the way i dint know over clocking voids warranty as it states -+10% overclocking,underclock in your website on s4. what i did is like 5% increase in frequency i guess.

Actually the exact phrase on the BitmainTech shop product page is "Over clocking: About 10%, but not guaranteed". To me that suggests you can do it but it can't be guaranteed that it will work properly. Also, I have looked through the BitmainTech website and can not find any warranty information on their website or in their manual.
