ANTMINER S3+ Discussion and Support Thread

[Bitskint]

Would it now be possible to run two Antminer s3's off a "Corsair Builder Series CXM 750W Modular 80 PLUS Bronze Certified ATX/EPS PSU"

 http://www.amazon.co.uk/dp/B00ALK3QRS

I have that PSU, and if its 340W / S3 for 444 GH/s without OC i dont see how you cant run two S3 with 1 Corsair CX750M. Its 680W total and maximun its 750

Because its worth it to do OC till 478 GH/s if you are lucky and you can? for just 34 more GH/s ?? or better not to? . I think i wont do OC because i prefer 444 GH/s @340W

Would not be able to OC as there is only 4 PCI-E cables on that spec

though Scan say four in one place and 2 further down the specs ---

i see 2 pcie cables   each with 2 jacks.


 that is not enough  unless you run the gear at 400gh  and  most likely  that will overheat the wires.

I found a photo of the cables on www.newegg.com


http://www.newegg.com/Product/Product.aspx?Item=N82E16817139051


also it has only 2

  8 pin   pcie jacks in the psu   so   you need adapters from the lessor jacks  (a risk)

lastly the 12 volt rail rates at 744 watts       so that is 372 watts per s-3  .  my guess is this is not the best choice of gear for 2 machines

Spec is +12V at 62A http://www.newegg.com/global/au/Product/Product.aspx?Item=N82E16817139051, and 4 PCI-E 6 pin connectors, which might be be tight for 2 S3's requiring 340W each at the revised spec at the wall and 4 PCI-E connectors each.

Whole pack of P2Fool douches in here lol..  you guys are morons waiting to be robbed.. GL and ignored

Actually, it is much less moronic to "trust" a decentralized p2p mining pool than your average centralized one. (Both in terms of network security and handling payouts)

Anyway, I support the motion to call you names if you are really bitching about people that want promised information about a product in the thread of that product.

Why is DOA shares SO high?



17% work loss AND 2% fee..  oh yeah this is the answer.  Use Eliguis 100% FREE

There are only two cables but each cable has two PCI-e connectors for a total of four.

@whonesta
This is really not relevant to this thread but I will still try to explain quickly.

Your DOA rate of shares is always higher on p2pool because of the way it calculates work.
This however doesn´t matter for your payouts, the only thing that matters is the relative DOA rate of you vs the average users´.

IF a share is a valid block but considered DOA due to timeout, it is still broadcast on to the blockchain and counts as a valid block, triggering payout for all p2pool users according to the sharechain.

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.

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??

There never was too good a reason to do that and now there is even less of a reason.

I would also recommend sidehacks server PSU breakout boards for powering antminer products.

I bought another S2 , instead of having to wait for the S3. Only 0.55 BTC expensive. But there's no need to buy PSU and it Hash Rate is not 2x 441 GH/s or more .

We have a saying here in Estonia. "The first calf always gets behind the fence"  Similarly Antminer S3 Patch1, Patch2, Patch 3.

Purchase your Antminer S3 among Batch4. There are  better cheaper and  less waiting time.

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.

It was better to wait for S3 than going for S2.
Do your math and find out in BTC terms.
No issues if its to satisfy your urge.
Understand the fact that miners are hobbyist too.
As of now I will wait for B4 S3 to order further.

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?

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.

Yes.

Realised after I went back looking at some other PSU's.

I like Scan - they do good deals and take Bitcoin for their stuff

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.

I would think running the PSU @ 91% is a bad idea, this will cause highest fan noise and lowest efficiency @ the wall. Plus CXM 750 is only 84% eff on 120V. I like the AX or RM class of Corsair, but I do pay alot for my "Juice"

[TR8888]

Corsair's PSU's have gone to shit the last 3-4 years since they stopped using Seasonic as an OEM.

For me, The best value 750w right now is the XFX 750 pro/core/black , Seasonic internals, £60 each.

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?

They do spec well, but why don't they offer something in the 1KW+ market. I will be using the EVGA 1300G2 to run 3 S3's, since OC'ing looks like a no go for the first few batches no need to hook-up the 2 additional PCI-e connectors.

[allcoinminer]

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?
