ANTMINER S3+ Discussion and Support Thread

[allcoinminer]

So... it was said that S3 will only need 2 PCIe connectors to operate, or 4 PCIe if it is overclocked.

We have now learned that overclocking by only 37GH/s makes it unstable to the point that Bitmain won't even do it or it could burn out. Does that mean at there really is no good reason to upgrade all PSUs to ones with 4 PCIe to replace S1 with S3??  

-OCS

As per the new situation one PCI-E cable is enough per blade.
Even if its overclocked one PCI-E cable can easily handle it.
Don't forget to check your PCI-E cable rating in you manual or cable itself.
Most corsair PCI-E cables are rated at 600W. Also keep a hand on your cables to check whether it heats up to the point where you can't hold on.

Thanks for your advice everyone, So then  a "Corsair Builder Series CXM 750W Modular 80 PLUS Bronze Certified ATX/EPS PSU" would be ok running 2 x Antminer S 3's then? Or am I getting confused?

If we speak theoretically, you can run two S3s overclocked(if possible) to 478Ghs/366W.
If you are running at stock 441Ghs/340W your current CX750M is very much ok.
If you are buying this one consider a higher Watts rated like 1000W or 1200W.
Always buy power supply in consideration with you term goals. If you can arrange a server power supply that will be more good.
Check ebay, a lot of used ones are at through away price, most of the mare at good efficiency too.
Finally my recommendation is to buy a 1000Watts PSU if you don't have a PSU yet else
wait till you get the miners and check how its running in your current CX750M.

Thanks again all, on reflection I think I will air on the side of caution!
I have 1x Corsair 1200w + 1x Corsair 750w after learning about the recent update on reduced Hash rates, I was thinking about running all 3 Antminers that I ordered off my 1200w and perhaps will buy 2 more to run off the 750w. Or do you think I should still run 2 off the 1200w and 1 off the 750w?

You can safely run three S3 in your Corsair 1200W.
If you are lucky, and your miner can be overclocked, still you can run three S3s safely in this 1200W.
Now you can have maximum 4 S3-es. Three on 1200W power supply and the other one on 750W PSU.
If you have a kill-A-Watt or equivalent meter measure the power consumption and then order one more S3 later.
Maybe, S3 power consumption may vary from the rated when you run it at your side.

Doing the math on the compensation offer...

Assume you bought 2 S3s from Batch 1  .75 BTC x 2 = 1.5 BTC

A refund of 7.7% = .1155 BTC

A coupon for 10% off of your next purchase of 2 miners at the current purchase price of .725 BTC each = (.725 * 2)(.1)= .145 BTC
OR if the 10% coupon means 10% credit based on what you already spent =.15 BTC

Net difference is .145 - .1155 = .0295 BTC (or .15 - .1155 = .0345 BTC)  or about $18.29 (or $21.39)

That's only getting a $9 - $11 per miner bonus for rolling the dice on a future order, not knowing at this point how future S3 batches will hash, what the miner price will be, or impending difficulty jumps.

To me, it seems like money in hand is the better option.

Another compensation idea would be $600 off of an S2 and then Bitmain could clear out his inventory and people could get shipments of those in 48 hours...just a thought.

[contactlight]

I was one of the first ones to order and still unshipped. Not very worried, though. I just hope they shipped already.

Hope no more delay as it was suppose to be 10th of July.

Perhaps the 10% off coupon will apply to an unlimited number of miners on your future order, in which case the coupon will be of greater value.  Or maybe it won't have an expiration and you could use it when it becomes of maximum value.  But to me, it seems like money in hand is the better option.

Money in hand is the smarter option, but I'm such a sucker for coupons. It was such a brilliant move on Bitmains part, though.

Frankly, all that I just wrote can also be found in the wiki. Uninformed people that base their opinion on their knowledge (or lack thereof) like you are the problem of this society.

Really that is the problem, hmm. Well I read the wiki and all I see is more infrastructure I have to maintain, more up dates, and more waiting for FW so my HW does not waste countless hours to make NADA. The thing that is wrong with society, IMHO, is jerks who hijack convos with annoying calls for information which has CLEARLY been stated as NOT AVAILABLE. Continuing to hammer the thread asking the same stupid question about a P2Pool functionality which is used by < 1% of the network is only meant to cast a negative light on a GREAT manufacturer. If they are SOOO worried why don't they BUY one and write the FW themselves OR WAIT until BitMain updates the status for S2/S3's to "P2Pool READY" IF they bother with such a marginal user base.


AS FOR NOW http://www.eligius.st/~wizkid057/newstats/userstats.php/1CzqqXY4CDAhg9CY9gYzH1kCAHRcY3jrcm runs S1/S2's and SOON S3's very nicely.

Your claims are utterly misinformed again.

You do not have to maintain any additional hardware to mine on p2pool, just use a node near you.  (so no, there is no need to maintain anything additionally)

There is no additional downtime from using p2pool... why would there be? ( you can still use your favourite traditional pool as a backup if you have some irrational fear of downtime)

I do not think society as a whole has the same problem from people voicing their opinion on internet forums, than from people who make halfinformed decisions on problems they do not understand.

Again, your comments show that you just don´t understand the way how p2pool works so please, stop to science.

Even if it is, you're still only looking at a $10.69 bonus per future miner ordered.

That's what dulac97 said. I don't see how it doesn't add up.

Last 2 S1's got a $400 coupon  against an S2.
Wonder if there is a $400 coupon this time -- because that would make the S2's real tempting
having a PSU already included

$1610 minus $400 = $1210 = about 2 BTC

plus if there is the option for refund too -- makes it even more sweet

[oskuro]

Well i payed 2 units, so coupon would be around 80$ if its the 10% of total payed

[kp5995]

 "10.0% worth of coupon for the B1~B3 customers. This is the default option. (10% based on what you have paid for the B1~B3)"

My coupon should be worth 0.15 BTC. I'll take it as long as it doesn't expire to quickly.

10% coupon would 10% off the price you will be paying when you are able to use the coupon.  If s3 is 0.7 and you have to buy 2 for a total of 1.4BTC you would be getting 0.14 off for a total of 1.26 or 0.63 each.

Hello everyone,

When we were doing the first mass production, we found that not all of the S3’s DC/DC module could be stable enough to support the 478GH/s speed. After long time testing, all of the S3 run stably at 441GH/s, which however is 7.7% less than the 478GH/s we have announced.

So we decide the final specification of ANTMINER S3 here:

Hash Rate: 441 GH/s or more
Power Consumption: about 340 Watt at the wall when running at 441GH/s
Power Efficiency: 0.77 J/GH on wall
Power Supply: 12V DC
Size:  331 mm x 137 mm x 160 mm
Fans: Two 14038 fans mounted on both front and back ends.
Operating Temperature: 0 °C to 35 °C
Complied with: FCC / CE
Network Connection: Ethernet

Many of the customers may be lucky to find that their S3 can be overclocked to 478GH/s.

We apologize for this incident. We offer two options for customers:

1)   10.0% worth of coupon for the B1~B3 customers. This is the default option. (10% based on what you have paid for the B1~B3)
2)   7.7% worth of refund. We will release a function on our official website for application of this option. If you have bought from our resellers, please contact them and provide your Bitcoin address.

Shipping schedule updated:

Batch 1: The shipping will be finished in 14th and 17th.
Batch 2: It will be shipping out between 18th and 19th.
Batch 3: It will be shipping out between 19th and 22nd.

Anyone able to explain the bold text above?
What was causing the DC-DC module to become unstable and stable in some?
Anyone capable of pouring some technical or theoretical explanation for this phenomenon?

sure chips and most caps resistors whatever are -+ 5%  so the modules built had a lot of -5 % parts in them.

happens in the best companies.  INTEL has been making cpu chips that vary as much as 10% for overclocking.  why not the dc to dc module here have a larger then desired variance.

I am all the more likely to run mine at 400gh and hope for 280 watts. 

[denniscdunbar]

10% coupon would 10% off the price you will be paying when you are able to use the coupon.  If s3 is 0.7 and you have to buy 2 for a total of 1.4BTC you would be getting 0.14 off for a total of 1.26 or 0.63 each.

With the lower hash rate and the concern about overclocking ability due the problem found, plus diff going up when batch 4 is available, I wouldn't be surprised if s3 will be priced @ 0.704 or lower

Sadly it seems like the 17th and the 20th are the next two dates we will be waiting for. No communication from Bitmain to clear the confusion. I hope it all works out okay.

They're coming, trust me. And yes, I am poking the bear and legging it.

[Pistachio]

Partial refund sounds like the best option until we can see how stable these units are.

Edit: I might even go for a full refund if that was available.
