Not at the moment.  If they don't fix the problem, I'll find some other provider.

There's no Kill-A-Watt but there's definitely knockoffs available for 220/240V receptacles.

yeah all your chips are under the 115 mark for temp which should prevent chip death. at 7 cents you can bump to the 1500 and make a fraction more money then at 1300 gh.  

You also suffer noise since you max fan in a home bad

In a data center so what.

the op did not mention if noise was an issue.



and my power was 770 for 1300 yours was 990 for 1500 at 7 cents  your last 200 gh costs you 220 watts  so you are gaining 13 cetns a day or 4 bucks a month .  

big noise gain

Holy smoke - seems it was one of my old S3's that found that last block!

Outstanding 

It is easy to make the cables to go from a DPS2000bb to the boards with ring terminals or the PCIe connectors.

If you aren't handy with crimping or soldering, or simply do not want to fight more of the headaches I would suggest contacting sidehack and let him know what you need.

If you need help identifying anything I am happy to do so and will tell sidehack what is going on and give him the details of the situation.

It is not hard to make the correct cables with 12 gauge wire. I would revisit my saved information before telling you to use any smaller wire, but SHITSTAIN use smaller. I do not remember the size off the top of my head, but do have it and am happy to look it up.  

Keep this in mind: the main reason I did not want to accept the offer from SHITSTAIN regarding them sending me a 2000bb power supply to use as a stock replacement is it is not right and makes it horribly difficult to sell. Most people do not want to buy a miner with a modified component which is supposed to have an internal power supply. The cabling would have looked different, and I paid a lot of money to have a miner which was down more than it was ever up. Not to mention whatever liability issues you could run into if you modified something and then someone hurt themselves. And again mentioning the fact they KNEW and KNOW today they sold us a crap power supply, every unit has a board pulling too much voltage, and isn't clocked correctly when you do try to underclock, it still pulls the same, along with the other firmware issue. The unit never ran more than 9 days without a PSU failure. It was delivered from the SHITSTAIN factory in China around 01-01-15 and I was on the phone with them approximately a week later. Wash, repeat again after it took them a week to get me another power supply. Wash repeat again, same. I even sent them the entire S4 while explaining the issue was the hash board pulling too much voltage and I believed there may have also been an intermittent connection issue with one of the cables from the PSU. Wash Repeat again, but this time I was done giving them a chance. If anyone would like to know the actual timeline I have it all saved, with e-mails and tracking numbers, but I think you get the gist of my experience. Unfortunately I can change the PSU with my eyes closed.

I do think it important to point out that while Yoshi hides behind the BITMAIN Warranty Account posting on this board and spouting his usual rhetoric he does not deny these issues. He knows these things are true. He may throw out some random comment in an attempt to at least say something or put the scent on another item, but these issues have been clearly identified by many, many people over the past few months. The board issue where the voltage is not controlled correctly is way back in this thread, but again, clearly pointed out and outlined with all the data points anyone needs to confirm the problem. The power supply issue was admitted in the open, but the "batch 2" were not better.

They thought using the ring terminals was the big "fix", but their lack of internal communication or complete unwillingness to spend money on a proper fix for the overall issue is the core problem. Ring terminals are a better connector in this case, but it is not a fix. As you speak with him watch your six, document everything, and keep one hand on your wallet and the other on yourself.

Do not be surprised if he doesn't respond at all, or initially he responds with an e-mail which sounds great, but nothing substantial ever happens. Be prepared to take care of your own issues, but I hope with Prelude's recent posts they seriously take a look at this situation. The technical support personnel are much more professional and capable people. Use them to discuss the details of your issue. I made the mistake of contacting him when I was told to do so from a SHITSTAIN employee. If I'd known what I do now I would have stayed with the support guys. Yoshi gave me this spill about even though this particular unit was purchased through Amazon (Actually Zoomhash) and not directly through SHITSTAIN he would make sure everything was handled and take care of the warranty issues. I made another mistake of believing him as I waited days for information from him while the S4 which shipped from the SHITSTAIN factory directly to me sat not running.

I understand there may be agreements with distributors they receive a larger discount or other incentives to handle their own warranty claims and even support in many cases, but in hindsight find it extremely unusual for someone to act like they are doing me a favor to support this product for 90 days when it isn't even like Zoomhash could have done anything to the unit, they never saw it. AND if he had told me to contact Zoomhash instead of playing the "we will take care of it for you" game, I would have probably received an appropriate response from Zoomhash, but we do not know, because I was never told to do so, he said he would handle it.

 I was always polite and professional in every conversation and e-mail, but the simple fact is Yoshi talks a lot of shit, lies to you, and then expects you to treat him like he is something special. You are nothing without customer service. He tries to lay the blame on purchasing from a 3rd party. Why did he tell me he would take care of it then? He knew who I'd purchased it from THEN. I directly e-mailed him the exact same information I had sent customer support showing my detailed invoice and shipping information.

 It was after the fact that he realized, as he realizes today that I know enough to catch him in his lies, point out the defects in design, and the cheaply built components SHITSTAIN used in the S4. Then he decides to use his magic purchased from a 3rd party line, but it doesn't hold water to anyone with half a brain who understands the items being pointed out. It doesn't matter who you buy it from if it ships straight to you and has defects in design. It isn't as though Zoomhash ordered a different model and sold me something different, it is the same problems many, many, MANY others are realizing they have experienced or are experiencing now. He doesn't respond directly regarding any of the serious points with anything except to say they will look into it while he continued to ship more crappy product from China AND keep shipping replacement power supplies. But there is no real engineer looking into anything. Their "Engineers" are looking at next gen crap. If they wanted to correct this, it could have been done months ago.

He does buy people off. I have seen many people with the exact same complaints I have raised who go for days or weeks complaining saying the EXACT same things as I, but then one day it is they spoke with Yoshi and everything has been worked out.
Do you think he corrected the issues we all faced or face today with the S4? Of course not, he bought them off with more product, cloud hash, coupons and other items. One at a time, Garza style.

Back to the problems others are experiencing today:
I made my own cables and used sidehacks breakout board. Other than the aforementioned issues the unit runs correctly using that power supply and breakout board.
For the Euro users I am pretty sure sidehack ships there, but there is also Jabber's board to fit this same power supply. Him being in France might save you some shipping. I have not used his 2000bb board, but his IBM 2880 power supply breakout board runs great.

I will not sell the S4 this way though. Even though I know sidehack's boards and my cables work perfectly, you do have a liability concern in my opinion.
If it is a 'buddy' who I know understands what they are looking at / getting into I would probably ship it setup using a server power supply.

But again, I am happy to help anyone with issues.
The SD card vibrates loose quite a bit. Sometimes all it takes is to eject it and reinsert and it will boot.
I bought an extra one and copied the existing one.

For fans it depends on the clock speeds you are running. An overclocker would want to (at a minimum) match the S4 original fan specifications and I have them in a folder somewhere which I can digup. There have been many posts regarding Fan alternatives, but keep in mind the cable lengths. Fans never have cables as long as the ones SHITSTAIN designed in the fans on the opposite end from the controller card aka Beagleboneblack. So, you will need to purchase extensions, or splice some on.
You can get away with a more quiet fan if you underclock.

...but trying to underclock using the current firmware does not save you much in power usage since they removed the voltage functionality. Lowering the frequency does lower your power use, albeit slightly, but the issue is if you cannot set the right voltage you may as well not underclock. You aren't saving much money regarding power usage AND you risk causing other issues.  

You could run the older firmware which does have voltage adjustment, or you could talk to one of the few people who have created firmware themselves. It sounds like Prelude has come up with some firmware and he may be willing to share if we help him recover some of his investment. It seems he asked for anyone else to help when he started to find a coder and have the changes made he needed. I follow many of his posts when I can be here and missed where he asked for other people to chip in, but I told him I would definitely do so. I imagine if he has enough people to help him recover some of his cost he would share with the community at large. Prelude has always seemed to be fair and helpful.

There is also a post from a couple months ago where a guy made S4 firmware for lowering the fan speeds. There were many people using it and I remember reading nothing but good things from his changes. He even sent the code to SHITSTAIN and there were comments about them incorporating some of the same functionality but to my knowledge it never happened because the next firmware release was the one we have now. This one does help provide a more stable hashrate, but of course as I've mentioned and others, it screws the pooch on voltage adjustment. They did the same stinking thing to the S3s. (The S3 firmware has been crappy, buggy and has gotten worse since the 10-24-14 release with the broken reset button, but that is another thread) This shows their consistent screwing customers and limiting choices.    

 If you decided to use older SHITSTAIN firmware for your S4 please keep in mind there was an issue where the difficulty had to be manually set on your pool side at 2048 (going from memory on that number, I can look it up if needed for anyone.) If you don't do this you have all sorts of other fun, which was crap hashrate, and I am not talking about a little difference, I am talking several hundred GH in many scenarios. Going from memory I remember seeing 1.6 - 1.7 TH.
This particular issue limited people to being able to mine on specific pools. Vardiff didn't work correctly. IT was messy.  

PM me if anyone wants any help with any part of what I have said. I saved everything and can backup each assertion or piece of information with confirmed items.
 
Good luck to the folks dealing with failures today. Try to keep the stress from getting to you, it isn't worth it and let me know if I can help any of you be it power supply, fan, firmware, etc.

I have 2xS3 and 1xS5 that are still running.
The S5 runs 24/7 but the S3s are off during peak electricity cost (~50c/kWhr)
The S5 is usually blowing cool air out of it - they default the fans way higher than needed - so I had almost no problem with it during summer.
The S3s fans are slower and also warmer air coming out of course.

Awesome post Prelude.

Thank you for your time and money spent to this point. Whether S4 users get anything from it or they don't, you have made this particular issue clear enough. You included the appropriate details so everyone can understand and no one can deny or question the facts. That is hard to do in a short summary, but you did it well.

To be clear: I'm saw this device only from software side, didn't saw or touched in real life, so my thoughts about psu based on other owners replies(here and our local forum). I try to make my best to improve firmware, but i don't have control board to experiment with. I don't want my miners to be idle while i'm messing with bootloader.

Voltage and Frequency Control is set at the Advertised Specification to avoid damaging the hardware.  Wrong value in these area can stop the miner from operating or damage the parts or even becomes the FIRE HAZARD.  

Voltage used to be unlocked before the Jan 29th firmware. Bitmain intentionally disabled voltage modifications because they were dealing with too many blown PSUs. I understand why Bitmain locked it, but it's unfair to those of us who know what we're doing, the power users. I'd understand blocking it from going higher, but lower is completely stupid. Lowering voltage will only make your PSUs last longer before they die

S4 power draw is about 1380W when the PSU is 1400W.  When you overclock the S4, the power draw will be higher than the PSU may be able to handle.  The fans are implemented with RPM control to keep the miner cold enough to operate, when it is over clocked the heat management will more than likely not able to keep up and highly likely result in a damaged parts inside or the fans end up spinning at the max speed and shortening the life of the fan.

The PSU is actually 1440w, not 1400w. 1380w is AC AT THE WALL, not DC being pulled from the PSU. I would not recommenced overclocking with the stock PSU. In fact, I wouldn't recommend overclocking at all unless you know what you're doing and have replaced the PSU.. Underclocking and undervolting, however, is safer than running stock.

Under-volting option may or may not be available in the future but it is an item that is constantly looked into by the engineers in Beijing and Shenzhen. (S4 was not advertised to be able to under-volt at the time of the sales)

This is complete bullshit, sorry BitmainWarranty. The engineers are not looking into ANYTHING, voltage control was intentionally locked out, disabled, whatever you want to call it. This is a fact, with proof to back my statement.

Further more, the S4 was in fact advertised as being a great underclockable and undervoltable miner if you'll just look at BITMAIN's orginal post in this very thread. Take a look here:



That clearly shows that the S4 was sold as a product capable of achieving 0.48w/GH at the wall when underclocked to 100MHz and undervolted to 0.60v (0600v) while running at 1TH/s.  

Anyone know why S5s don't failover from WestHash.com when its profitability drops below the pw parameter

I would have expected a greater variance on the 5s hashrate than what yours appear to be showing.  On a sample of 10 units, I see 5s hashrates vary anywhere from <1TH up to over 3TH and sometimes even 6TH.

Done all the troubleshooting but it dint fix. The machines are at a hosting location.

The machine was power cycled and it started hashing again. But the main problem seems still unresolved.

When pool settings are changed for few times, machines stop functioning. Machine has to power cycled COMPULSORY to bring it back, it just becomes unresponsive to anything.
I mailed the bitmain the same and this was their reply, hope it helps someone.

i found that hardware problems and i fixed with cheating boards. but i dont know linux much well, i ask to smith that "how to rebuild initramfs" but he cant help me. if he show how to do that, i will fix that with bbb software, because i know this problems core. i am an 40 years old engineer, sorry for i am not linux guy. but also many thanks to PRELUDE,for to be my voice in this forum and for this biiiiiiiig problem.
DONT FORGET, BITMAIN IS CHEATING US
also we know cheap devices are pain in the ass but THIS IS NOT CHEAP ! THIS MUST TO BE PERFECT AS THEY SAID.
