ANTMINER S3+ Discussion and Support Thread

[spiceminer15]

I wouldn't be so sure. I think they can squeeze 2 TH/s out of 1100-1200W.

2000G * 0.7W/GH = 1400W MINIMUM...OK...

The assumption is that the S4 works with underclocked/undervolted ASICS to reach a better W/GH ratio, I would assume somewhere between 0.55 and 0.65 W/GH, so one 1300/1400W power supply could indeed do. But of course we'll not know for sure till @BITMAIN reveals the exact specs.

still, they wont give you something like
Evga 1500w Platinum      


and, btw...
5units of S3+ = 355w x 5 = 1,775W

i assume S4 will be around 1500w - 1700w
they wont waste chips like that..
they better selling chips like avalon do than planting so much undervolted chips
and sell it so damn cheap 
they're not doing charity here buddy 

they "wasted" them like that on the s2....


the s2 chip freq is 192.... the s1 is 350

This is my thought. I don't know if they'll under clock enough to run on the 1050w supplies like before, but 1200w supplies are reasonably common and we'll priced enough that 2th/1.2kw seems like a fair target, and if psu is included it would justify a 2.4btc price tag

I agree I have all my S2's upgraded to 1350W Platinum power supplies and over clocked to 1.11TH so I think with new chips and 1300 Watt power supply close to 2TH is a good target or 1.7TH is acceptable

In the U.S. a standard electrical socket is rated at 1600w max. I believe, so I don't think they'll go over that.  Would be nice if a 1300w single power supply would be able to handle the new S4 with the EVGA G2 so cheap right now.

[Tips4TaT]

If the price and/or power of an S4 is equivalent or even a bit less than S3, I’ll stick with the S3’s. Can’t afford to lose 2T if the box goes down… Having a nightmare of time with my CoinTerra shits boxes…

S2 was sketchy in the beginning, but my later batch S2 worked for 20-30 days straight with no interruptions. It was great.

[edonkey]

We are glad to share the news of ANTMINER S4 2TH/s, Batch 1 will be on sale this week, shipped before Sept. ends.

Bitmain, can you tell us the dimensions of this new unit? I'm interested in rack mounting it if possible.

Will it have "ears" for rack mounting, or at least an option? I'm not a big fan of installing shelves to hold boxes like this.

I'm of course interested in the price as well, but I assume you're not going to pre-announce that. However you must already know the dimensions of the box if you're shipping before the end of the month, so hopefully you'll answer my question.

EDIT - Sorry! I'll ask this on the S4 thread instead

A 20 Amp 110 v circuit can handle a continuos load of roughly 2000 watts, not 1600. Give or take a bit of course.  Most new construction uses 20 amp breakers.

Strato

For continuous load you should not put more than max 1650w on a 20amp breaker, or the breaker will get hot and eventually burn out. Just like your tires going on the road 100MPH all the time. The formula for continuous load is subtract 25%.  If your wire or breaker feels to hot then you are doing something wrong. 2000W is a no no.

[bspurloc]

It looks like the S3 upgrade kits dont come with the enclosure...

 which I must assume is going to make them run hotter than an S3...

Does anyone have some slick ideas for an enclosure to get around these? CHEAP not something someone made.

Besides taping cardboard around them, which I may end up doing.

Or I may just fabricate some sheet metal.

You don't need an "EVGA Platinum".  You need a good, high efficiency server power supply, and you for sure don't need 1500w to power 2TH.  A server class PSU will beat the pants off of any consumer model at any time.

You will get higher efficiency out of a server-class PSU, and even better if you're running on 240v instead of 120.  Take a look at the SPTech specs for their servers, and do the math to see what they're pulling, and they're doing it at 90+ efficiency.  The one thing I'll give SPTech is that they are built well, using (supposedly) higher end server grade parts.

By undervolting you achieve several different things.  Yes, you lower your hashrate, but you also lower power draw significantly, lower heat generation, and raise efficiency which allow you to get higher numbers with much more stability.  The ASIC chips themselves are cheap, they're only "wasting" a few bucks by having to add a few more when undervolted.  Seriously an extra hashboard to them is probably $50, so when you're dealing with a $1000 server that's really not much at all.

We will just have to agree to disagree there. If a breaker is rated at 20 amps load at 110v it will certainly hold 1920. I also speak from experience here. Long term loads of 1800-1900 months on end. No issues. But yes the breaker will get warm.

No, they are supposed to bolt up right to the same frame structure as the S1, reusing it.  Honestly it shouldn't be any worse without the enclosure around it if you have proper airflow.

As for an enclosure, I'm working with another member on a rackmountable chassis to hold a few S3's (you can find the initial thread I think under group buys a month or two back).  Hopefully the first prototype will be delivered in about a week, and the idea is to fit 12 S3's worth of blades and server PSU's in about 10U of rack space.  If you PM me I'll get some pics of it to you when done (I won't want to search through pages of this thread in a couple weeks to find you...  )

Standard outlets are rated at 15 amps.  Outlets rated at 20 amps look differently.  A 20 amp outlet has one of the two vertical slots having a T shape, the T on its side.  Next time you're in Home Depot or Lowes take a look.  Interestingly the 20 amp outlets have a clamp type wire hook-up.  It's not to say that a general contractor building kitchens won't put a couple of 15 amp outlets on a #12 gauge Romex circuit to a 20 amp breaker.

I was just looking thru my server room and extras and I think I actually have 2 rack mounted enclosures that were made for putting XT mother boards in them that may just work haha...
 I presently have 3 S1's stacked and tied on top of each other and some others sitting on the floor at the bottom of some racks. They are all sitting at 41-42C so I guess I shouldnt even need to care about keeping things cool if I have s1's running that cool and overclocked. I have S3's sitting out in the office area and they are at 42-43 and super quiet where and S1 out here would be at 46-47 fans blazing. So it just seemed to me those enclosures were really helping keep the s3's cooler.

ha ha  ..it is exactly what they did in my house-dinner room 20A circuit (I checked), all outlets there are of regular size (no T), the same in the garage (the only difference is that it says GFCI on outlets).

I cycled a circuit breaker last night. That caused both of my S3s to not hash when they came back up. The fan in the S3 is running, but it does not come up.

The power on sequence goes like this:
Red light flashes for about 20 seconds
Green light comes on for a second - at the same time the network link lights come on
The red and the green lights go out at the same time. The network link lights stay on. The fan stays on.
They do not respond to ping or login attempt.

Each is on a 750 Watt Corsair PS and the whole lot is on a surge protector.

Did I kill them?

Did you set them to DHCP or manual IP? Try one at a time, also try to connect to the default IP. Failing that try to reflash the micro SD card, you may have killed that.

I will certainly agree with you there, the S3's are for sure quieter and it seems a little cooler.  Honestly it seems the open S1 frame is cool, but heat just flows everywhere out of it.  With the covering on the S3 it tunnels it better through the boards and out the back, at least better directing the airflow.
