Why are my S4 going up in flames an off topic discussion as opposed to hate on Dogie and BAN? This is a S4 support thread is it not

sorry about that, I have no clue how that appended to your message… I was talking about the back and forth bickering. I personally think Dogie needs to just stop responding to certain people… That would be the professional thing to do .

Did you see the video I posted?

This wasn't a burnt smell only. visible smoke billowing and this was after it had calmed down a bit.

Nice video, looked about the same as my setup…

I had the smoke as well, but on inspection I feel it came from the grey pad that is attached to the inside of the unit… I still feel there was no risk of a real fire, short of having a ton of news papers around your miner…

For the record I was on a 230v during my psu burn. This is no joke...and no inverted commas...frickin thing almost brought the whole place down if I wasn't there.

I think these units are UL certified so that should limit any risk on the house going up… I had one blow in my rack on a rolling reboot of all the units. It made a noise and had a burnt smell. On inspection I can see where it tried to burn but the steel case that the PSU is in prevented the spread of fire nicely .

This is off topic, take your back and forth somewhere else please .

I had one of those "exploding" PSUs. After contacting Bitmain it only took ~1 week after getting the replacement PSU, but unfortunately the miner still does not work.
When starting the fans are running at highest speed all time, without slowing down (not even after 10+ minutes). Furthermore the display does not show anything and the device can not be found on the network, even not after resetting it. I assume the controller board also has problems after the PSU "explosion", in fact it stinks a bit as the PSU did. What can I do now?
Is there a safe way to disassemble the controller board without destroying it? I tried to pull one of the cables which lead to the hashing units carefully and had a feeling that the whole connector is going to come out...
Kind regards

P.S.:
Already contacted support yesterday, but did not get a response yet.

Do you have some pics? Another miner I know had the same issue with the S4 PSU catching on fire using a 110V source. He got the runaround from Bitmain who offered only to replace the PSU; he even talked to the Bitmain rep at the booth at Hashers last week. This seems like more of an issue than Bitmain is willing to let on.

I don't think there is any reason to blow this out of perspective, I have 4 units and one of the PSU's exploded. Bitmain told me that they are sending me replacement PSU's but I have not seen anything yet. I also provided them with pics of the unit and I have not yet got my 10 day return on my downed miner but I'm content on waiting a little bit for that. My only concern right now is that I have one unit completely off line.. I know it will get resolved, my ONLY concern is the amount of time it takes.. Due to the price and cost of shipping of these units I'm REALLY up against a wall for ROI … In short I'm trying to say, I feel Bitmain will resolve all of this but its going to cost me money in the end …

Take a VERY close look at your control board. there is a good chance that when the PSU blew it took the control board with it . If you have a good working S4 Bitmain will advise you to try and switch it out with a known working control board ..

Hi... For those using the batch 1 PSUs the burning down thing is a real risk. I just avoided a near catastrophic disaster. The miner wasn't powering on so I decided to try another power cable and it turned on and was running fine and even started hashing. Suddenly I heard the fans going nuts... And when I went into the room a chemical smell was in the air and smoke was billowing out of my psu.

And just so that you guys don't say I am bad mouthing Bitmain here is a video I took right after I turned everything off. The cable is a proven cable and there are no signs of melting on it.

Please kindly let me know what compensation Bitmain can offer. They have not responded to my emails on the psu replacement.

When my S2's do that it is always the SD card on the beagle controller...try reseating it. You might need to re write the image.

Has anyone played around with overclocking settings yet on the S4? I usually do some hands on experimenting myself but with the power supply failure I wasn't able to tinker much I will have some time over the weekend to play around and document the changes like I did on the S2's

we get the antminer s4 yesterday (15-10-14 ) , but the hashrate on the pool isn't 2 but between 1.65-1.75 , do you guys did something special to get those high hashrates???

Set the difficulty manually to 2048.

tanx for quick answer , can you explain some more how to do that ( Set the difficulty manually to 2048 ) , it is my first real miner , so some help would be great

i set my miner configuration , url , worker , pass and it works but that is all i know off this machine , but i love it a lot

Its done via your pool's online configuration, but only some pools allow manual difficulty setting. Ghash, btcguild and slush's all do.

tanx it works , it runs a lot better now , de S2 's also , should have done this long before , tanx for info
