Would something like this apply to the S4 to mine multiple pools simultaneously? https://bitcointalksearch.org/topic/bitmain-antminer-step-by-step-how-to-setup-balance-mining-tutorial-395721

Or how would we achieve that for the S4?

This is Tim Shao from Bitmaintech.

At last! A real Bitmaintech employee who can offer some real support, not a moment too soon either.

I hope he cleans up all the dogie poo left on this thread...... Cheesy

I have all my PSU's on the way, so that's the good news… Has anyone received their 10 day mining compensation ? I keep asking for mine via email, and its the only question that seems to come back not addressed …. Just trying to put some feelers out there as to if others are seeing any of the compensation .

Hi, yesterday I received an email about sending 3 new PSUs and information that other 7 will be shipped ASAP. I was really happy because I have had 3 miners without PSUs, but not for a long time. Nowadays I have 10 pcs S4 B1 and 10 pcs S4 B2 and a lot of S3+ miners.

Today morning when I arrived to work I smelled burnt stink. Employees were scared, called me and ran around. WTF I said for myself. I hoped that the reason for all arround was not caused by miners but I was not right. I looked at the miners and two of them were down. Immediately I switched off all breakers dedicated for miners. And yes, one miner had PSU burned down. It was very easy to find which miner was bad Sad It was the fourth failed PSU. I checked all breakers and only one was switched off automatically.

When the smell disappeared from the building (after 2 hours) I started with switching on the breakers one by one. After that I switched on PSUs on S4s. But another one from B1 and also one from B2 could not start. Also fans were stopped. I tried to reconnect the power but nothing helped. I have not understood what happened. All miners were running more than one week continuously.
The PSUs do have really some problems. I hoped that PSUs in B2 were good, but....or today is only bad day for mining Smiley

Today status is 5 failed PSUs from 10 pcs from B1 and one failed PSU from 10 pcs from B2.

Truly sorry about that, Sir. This is Tim Shao from Bitmaintech. You may have received an email from [email protected] asking you to specify the PSU type. And i wonder if you can provide some photos to show us the burned PSU, i'm not asking you to risk running the miner again. But it does help if we can glean some actual info from the affected customer and submit them to the PSU supplier, and this will also help us improve the product quality to prevent this from happening again. Thank you for your understanding.  
I have the following questions:

1.
"I looked at the miners and two of them were down. Immediately I switched off all breakers dedicated for miners. And yes, one miner had PSU burned down. It was very easy to find which miner was bad"
Two were down, and one miner had PSU burned down? Which one was burned down? And what about the other one? Stop running? cannot power it up?

2.
And you mentioned in the following posts that your B2 has barcode on it and you are sure it's not from the defective batch, can you provide me your order id for this miner, or would you please send me a photo of it? Thanks.

Hi all, yes I have received the email. I am sure that the PSU is from batch 2 (have sticker and SN). 
Answers for Tim.Shao19:
1. My miners are connected in pairs to single breaker(2xS4 to 1xC20 breaker). When one PSU burnt down and breaker for this miner went down also another miner switched off. Is it clear?
2. Order is 00120141014004349482tuQeQyd106EE from 2014-10-14 00:43:50.0. PSU SN:188A410120045 PSU don't have visible changes outside and also inside.

Got my 2nd batch 2 S4 yesterday, plugged it in and it is hashing away after opening and checking power supply.  But when I did a status check of my first
batch 2 S4 I saw that I have 4 asic chips showing x's...  0 on 1st, 1 on 2nd, 1 on 3rd, and 2 on 4th.


How many chips need to be not working before doing a return?


more than that. 4 non-working chips is like a 3% deficiency, isnt it?

try a reboot, both through the software, then at the wall - usually that fixes these issues

Today status is 5 failed PSUs from 10 pcs from B1 and one failed PSU from 10 pcs from B2.

Can you confirm that the B2 miner that failed had a sticker on it? Early B2 units were shipped out with defective PSU also. You can see it by removing the top, no need to remove the PSU. (on my B2 anyways, maybe the sticker is elsewhere on others)
Yes there is a sticker. On the other hand I have to say this B2 has a bit different inside in comparison with B1.

How does it look different?? My B1 and B2 are identical inside.

Your dead S2 PSU could just be bad luck, everything has a failure rate. If there are more reports of dead B2 PSUs I'll pick up 2 DPS2000 PSUs to power them and have peace of mine.

Please check if the ones failed look like this or not. If your PSU looks like the photo, then it's from the good updated PSU. But if it doesn't, then that's probably why the PSU failed.

But if it looks like the photo and still failed, guess Bitmain did something wrong again and didn't thoroughly stress test the new PSU.

So can you please confirm if any of the failed PSU that you are experiencing looked like the photo?

If there is no barcode sticker on the PSU, then your PSU is still from the defective batch. For the one's that died and have a barcode sticker on the PSU, did you overclock them or they all running stock? Wondering if the extra overclocking is putting stress on the PSU overtime.
I am sure that this is new one not from defective batch. I have had default setting with cgminer from Ckolivas. Maybe when sticker went down the PSU had stress or something else...

Thank you to everyone who suggested setting difficulty in this thread on certain pools.  It seems to help and start fine tuning very quick after getting it Smiley.

If you haven't yet, try this.
Changes won't stick across power cycle, but it does make a noticeable difference.
Combined with setting pool difficulty to 2048 it should get you to advertised speeds.

 Angry of course, a proper firmware should eventually be made available so that nobody has to do any of this Angry
Oh well, maybe for Christmas 2015.

Assuming your S4's IP address was say 192.168.1.99:

Code:
ssh -l root 192.168.1.99 (or equivalent with putty)
wget http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer
mv /usr/bin/cgminer /usr/bin/cgminer.bak
chmod +x cgminer
mv cgminer /usr/bin/cgminer
/etc/init.d/cgminer.sh restart

I think that might not keep across a power cycle though.

Evil beware: We have waffles!
just got my tracking number too.. but here's the question, do they expect us to pay for the import duty? and same with sending their psu back to them as suggested in the last email? cause thats gonna hurt my wallet if i have to pay for that again..
Duty? Not in the US at least. Is part of the shipping cost.
As for returns/replacements. No duty as long as parts are marked as warranty replacements. Even if Bitmain wants to old one back as long as marked as a Return no duty applies (plus if any did would be their problem, not yours)

My PSU is also on it's way.

Anyone? I'd like to make the change to lowmem permanent also.
Apparently the permanent filesystem changes need to be made to the filesystem in /config ? I don't have one of these btw, I only had temporary access to fiddle.

Thanks for the tip, I'll try to figure that out later. If ever you need access to an S4 for any reason, just contact me. I have a batch 1 and a batch 2 that you can fiddle with.

I don't think so. They shipped me a new control board to replace a faulty one I had in an S3, marked it warranty, I didn't have to pay any duty.

And if they ask for the old PSU to be returned, I'm assuming they will send you a shipping label for UPS and all you will have to do is drop it off or have it picked up (that's what I had to do with my faulty control board), didn't cost me anything.
