ANTMINER S4 Discussion and Support Thread

[chipxtreme]

Outstanding. Good job, Bitmain. How a company reacts to a problem says everything. You will be rewarded by your customers for taking care of them.

Anyone have $200 coupons for a reasonable price? PM me if so.

I've got one i'm willing to sell

I know this doesn't necessarily mean anything, but APLUSPOWER not having every certified any PSUs for 80+ certification kind of bugs me. Do they operate under any other names?

Who knows, APLUSPOWER could just be a brand name of someone else.

Perhaps this got missed?

I've created a new binary for S4

http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141014/cgminer

Usual warnings apply, seems to work in places where the other one didn't. Supports --suggest-diff though only ckpool has that implemented. You should probably add --lowmem to your command line options for it.

I found other issues in their driver and addressed a few with some more hacks. I could only get 1.7TH ish but this was on some pools that previously wouldn't work at all. The driver could be made to work reasonably if it had extended attention, but please don't carefully pick apart what I say and use it in ad hominem attacks.

Thanks for your hard work.  Do we just upgrade the firmware with this file.  If not how do install this on the miner.

On the other side of the coin.....

I have 2.242TH minerside and 2.23TH poolside @225Mhz clock on stock PSU using 1600W+ pointed at slush.

I think Bitmain is a fine stand up company. I look forward to my replacement PSU.

[MikeMike]

I just received an email from Bitmain Tech about getting replacements for our S4 PSU's.
It included a link to this thread.


Are we required to go through the replacement process here?

[Bogon]

You are required to do what bitmain said to do.
Attach a copy of your purchase - as a pdf and reply to that email.

Anyone else choose Umisoo hosting? Do you just pay the hosting fee up front they show in the "Orders" page before it starts mining?

When you select it in basket there are links to the information. They will ship the S4 to the hosting directly, but you also need to make an account with Umisoo.

That part I have done. I'm talking about once you log in to Umisoo. Tracking number shows they received it yesterday.

When I log in, it doesn't show any hardware but if I go to the "My Order" page, it shows an unpaid order for ~0.33 BTC. It also says "You must make a payment within 1 hour, or your order will be cancelled."

So my question is, am I supposed to pay that invoice before they actually start the mining? I'm worried because it most certainly has been more than an hour since I didn't even know that was there.

We are happy to hear about the good news.

Yes, you should pay monthly hosting service fee upfront. (This support for Umisoo is unofficial)

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.

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

[FlensGold]

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.

[Blazed]

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.
