ANTMINER S3+ Discussion and Support Thread

[mrpark]

Is the S3 still being produced, or will it be back on sale again soon?

they are not currently selling on Bitmain, but ebay sells them for 287+ ship. Hard to ROI at that price... Maybe S3+ will be restocked soon, better to wait....

The fans give a speed indication output.  I don't know what kind, digital or analog.  The fan speed is controlled by pulse width modulation.  I don't see a corresponding hashing board temperature and fan speed though one goes up so does the other.  If I saw three miners having a 40° board temperature and all three have the same speed, I'd say there was a digital feedback loop but this is not the case.  So, one might assume that there is a ramp or curve that says when the temperature is A the fan speed supply voltage will be X, temp B gets voltage Y and temp C gets voltage Z.  The speed indication just giving an indication of change versus temperature to the user.

The bad hashing board having a declining hashrate and a declining temperature might indicate the fault is elsewhere except that even after a cold start, after significant cooling time such that hashing starts over 442 and works its way down over hours, shows a lower temperature and fan speed early on.  If that slower fan speed causes errors away from the temperature sensor, those ASICs may shut down engines and slow hashrate but not quickly effect temperature indication.

So the slow fan speed relative to temperature should be addressed.  The problem may be in the pulsed width voltage supply line.  A partial open, high resistance, in a plated thru hole, e.g. dull drill bit left fiber in the hole, the hole only partly plated.  So, that's where I'll look first when I troubleshoot.  I'll follow the pulsed with fan voltage first, then the ground and perhaps the speed indication pair, looking for something amiss.  But not today.

one of my upgrade kits isn't working. I think it's has something to do with the fact that it's showing 4 chains under miner status. Please help:

when will the S3+ Batch 10 be listed?

Sooo... who's thrown away their BTC on the S4 already?

Not I.  That thing will never make back the BTC you spent, even with free electricity, unless something crazy happens to the increasing difficulty.  If the price of BTC goes up I may consider it.

how much off were the coupons for S2 owners? Just curious

Good info there thanks. I hadn't seen the updates item.

LOL I laughed out loud when i saw $1450 EXCL shipping - felt it may have been worth it if it was based on around 2BTC but fk that im happy with what i got and in light of the fact that its gonna be noise-E-errrrrrr than an SU-37 taking off on full afterburner - have decided to pass on these. Blatant ripoff in my opinion.
Blatant Blatant price gouging by a company that has probably had 5000 of these in a datafarm for the last 6 months.
Very unimpressed Bitmain!!!

happy with my 18 S3's

can someone explain this to me? What is wrong with this picture? I am running the latest image.... Fans even hitting 12,400 RPM, pretty soon my S3 is going to be flying around the room!

I'm also getting very high fan speed readings on the 2nd fan of some S3's.  I don't think that it is the real fan speed, only some software error in reporting. The sound is similar to the other S3's that report a more 'conventional' speed. (Don't rush to tie your S3 before it flies away...).

Cheers

Selling S4 coupons for 0.25 BTC each. Send me a PM

how much is it worth? by bitmaintech...this one coupon ?

[mrpark]

Sooo... who's thrown away their BTC on the S4 already?

By the time you got your money back on the S4, there would have been 2 or more difficulty jumps. Anyone who bought this, even with the coupon just has a room heater.  Also, fans are very loud, do you see how fat those fans are? I think people are underestimating the noise this S4 is going to make. Same thing with the SP20.

I bought the Prisma ASICMiner 1.4Th/s for only $670 and that included the controller. I believe the Prisma is much quieter and smaller too.

Ah, my problem S3 has been running 1d 16h and has slowed to 418.15.  Three hours ago it was 418.80.

I have been in an acrimonious email exchange with the reseller.  So, for me to ask him to submit the slow hashing blade for exchange would beg an extended delay.  To request an exchange from Bitmain would probably be met by an instruction to return the slow hashing board to the reseller.

I'm not certain it would be in my interest to return the hashing board.  If Bitmain would accept the board directly what is the estimated turn around time?  What is the estimated shipping from the US?  Answers to these questions would help inform my decision how to proceed.  Thanks.

I had a friend that had to RMA a hash board with Bitmain. It took about 2 weeks from the time he shipped it to the time he got the replacement in hand. Mind you, his was completely dead so it was no loss to him to be without it.

I have one where the fan speed is reporting as way too high seeing how these fans max out at 3000 rpm. I just ignore it because sound comparisons are telling me the fan is not spinning that fast and is in fact spinning at the proper speeds....

It would be nice to see why they are reporting this. I would swap out some other fans and see if its a faulty fan sense but logic dictates its a software problem because if the fan was actually reporting that speed the s3 would NEVER adjust it higher when it gets hotter and I hear the faulty reading s3 changing its fans speeds when it gets a little hotter....

Side note on your pictures.... 50C 51C?? wow you running those way too hot...
the ones I have sitting just out in the open not in a server room are at 42c/40c. u live in a bakery?

I realise that you may have tried this, but one of my S3s is similar to yours and gets slower and slower, eventually ending up in the 300s, so when I can see that its average is going down towards 420 again, I reboot it.  On the first or second reboot, it starts hashing at around 460 or more, with good speed for hours until it gradually starts sinking again over the next day or so.  With this method, I keep it averaging 440 for most of the time, which I can't complain about.  Sorry if you already tried and discounted this!

I was directed here as maybe a quick fix for a problem. Please point me elsewhere if appropriate.

Just set up two s3 b9's with identical PSU's and ran fine for 4 days till I needed to change one of the configuration settings on both devices.

I changed the setting (password field for the first pool, actually getting used as a hashing control for a lower limit of payout acceptable) and then clicked the "Save&Apply". I monitored for a while and just got to wondering "did the setting actually take effect properly" as things didn't seem kosher, so I used the reboot option from the web page on both devices.

On reboot one would not display a good status LED (although the NIC LED's look good). Both the red and green LED's are dark, not even brief flashing (even though they did light till the NIC cycled). If I try to access it with the browser I get the initial page "LuCI - Lua Configuration Interface" but the auto link to the status overview eventually times out. It also doesn't generate heat (I have them side by side and there is a big difference in heat output between the working one and the failing one)

I tried leaving the failing one off for 20 minutes or so. That didn't help. I then swapped the PSU's on the theory that there wasn't enough electrical output on one PSU. That made no difference, working one with the other PSU still worked, failing one with the "working" PSU still failed.

Thoughts on what I could try that won't make it so I can't return it?

Yes, I want them to run hot because I make eggs in the morning on pan on top of the miner, and cookies in the evenings I run these in my office, I have 17 of them plus other miners in a room with just one 6" vent. The degrees is about 95-100F, and there hasn't been any problems. Chips don't need to be that cold, they just need air over them to run. All the miners have been running fine, its just these funky readings and the fans do move faster, but I don't think they are REALLY going 12,000 RPM or they would be extremely loud.
