Does Ck's custom S4 cgminer build located here: http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer still need the difficulty manually set on the pools?

I can mine pretty much anywhere with them since I updated to the latest firmware + installed Ck's custom S4 cgminer build. I haven't tested eligius for a while, and while it didn't work earlier I'm confident it would now. I could test it if you're curious?

I've been mining with p2pool lately and it's working perfectly.

Has anyone reported issues with running these on North American 120V residential circuits ? Contemplating picking up a Batch 3 if it comes out. Seems steady improvements are being made to the S4.

You are a fan of a miner that won't let you choose what pool you want to use? I use eligius exclusively and I didn't read ANYWHERE on BITMAINTECH.com that the S4 would be exclusive to pools that allowed you to set minimum difficulty. So to me, even IF I could get my S4 working, it would still be worthless, because I can't use the pool that I choose. Why am I the only one who finds this outrageous?

I received a Batch 2 with a PSU that was DOA on Thursday, October 16th. BITMAIN support apparently didn't believe me for the first several days as they were "sure" that my S4 was sent out in the batch with the new PSU's. I finally got my replacement PSU today and it seemed to work OK for about 3 hours (although I did notice that one of the four hashing boards wasn't hashing), so I decided to re-arrange the PCI-E cables (there are like atleast 8, and you only need 5, one for control board and one for each of the hashing boards) and guess what happened?


The brand new PSU that arrived today now will only power the control board. If I try to connect even one PCI-E cable to anything other than the control board, the PSU shits the bed and the green "Run" LED shuts off and the red LED light turns on where it says "fault" and the orange LED goes solid where it says "Alert". Not only that, but I can no longer power the unit using my own PSU's (which are actually used to power my S3+'s, otherwise I wouldn't have bothered with asking for a new PSU in the first place), which  I was able to do until this new PSU arrived. However, the PSUs still power my S3+'s, fortunately. I have yet to hear back from BITMAIN support staff concerning today's new issue, but they refused to compensate me for my 12 days of lost mining, and I don't anticipate that I will get the result that I want at this point, which is a complete refund, because I have spent HOURS of my own time (which is valuable to me) fixing a miner that was advertised as "plug-n-play". my fingers have been cut up by the fucking heat sinks and I'm going to have a hell of a time removing the blood stains from carpeting/clothing. Since when is it the customers responsibility to fix a broken miner? I have been an extremely loyal BITMAIN customer up to this point, but now, I am going to do all that I can to make sure that no one has to deal with what I have had to put up with.

So for anyone considering buying an S4, let me be the first to warn you, they are pieces of shit. They use cheap, unreliable, non-brand name PSU's, and at this point I have about as much faith that they will do the right thing and give me a refund as I do that BFL will give me a refund.

This is nothing short of criminal. Just because up until the past few weeks BITMAIN has had a relatively spotless reputation doesn't mean that you should blindly believe that they will continue to take care of their customers when its obvious that something is VERY VERY WRONG.

Look at all the poor people who are stuck with S2's waiting for firmware. OPEN YOUR EYES PEOPLE, haven't you noticed that BITMAIN has been making a hell of a lot of promises that they can't keep?  
Has anyone actually received compensation for their downtime? Where is BITMAIN, the user? not BITMAIN SUPPORT or DOGIE, but BITMAIN. If you are reading this, this is a WONDERFUL opportunity to explain yourself and get your shit together.

My first and almost certainly the last S4,
worked with EVGA G2 1300W  and  waited for new  PSU  over a week .  
Max 1200W ,  Frequency 181,25M  GH/S(avg) 1800 , at pool 1630

Im a bit confused …. in one of your responces you posted "As for the compensation, we'll  exercise discretion in light of the circumstances."

In your Info Release you stated that you would give 10 days mining compensation to people who experienced a critical PSU failure . I have received my RMA from my critical failure, I have provided you the pictures of the PSU with burn marks all on the inside of it and the melted flux on the PCIe connectors. What other discretion do I need to submit proof of ? I have asked the question several times here and submitted it to the support email … My unit was down for far more then 10 days, but I'm only asking for what was stated in your press release on these PSU's… 

I recieve my s4 b2 today, but its Dead On Arrival, I think the PSU is dead. My first disappointment after I purchase alot of bitmain miner.
Send RMA request lets how it goes...Btw can I use my normal PSU to run the machine?
Thanks

Same here with my B2. My B1's PSU died, but it was replaced quickly. All in all I'm a fan of the S4s. CK's updated cgminer helped a lot too.

Assuming your S4's IP address was say 192.168.1.99:


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

It's a shame there were so many S4's out with problems.

Mine came in, I manually set difficulty, increased the frequency and consistently hash at 2.3TH no problem and no complaints.

Like he said, you have to hold in the power/reset button in the back by the plug for a few seconds for it to power up.

As for using other PSU's, per what my UPS reports, power pulled 'from the wall' is 1,450-1,475 watts.

Is this your only S4 ? Did you hold the button in on the back of the PSU ? You can not just plug it in, You have to hold in the reset button for a few seconds … You can use another PSU while you wait on a RMA but remember you need a high end one… A RM1000 would only power half the unit, two hash boards and one controller, that would give you 1 THs.. an AX1500i would more then likely power the full unit … can not guarantee that, but by the numbers it should work..
