dogie, good move for bitmain guess they do listen. Q. Can you find out what the decibel level is trying to figure out if this is going to be too loud for home.

Edit-- Didn't see where you were going to look into it from the earlier post, thanks.

Yeah I'll test my unit tomorrow as long as UPS doesn't mess up.

UK link is bad dogie, displays a BITCOIN MINER T-110S.

Copy paste fail, fixed. Can you delete the bad link from your quote please.

DONE

And yes, I deleted my own post, your link is good now.

This means I won't sit here and reply to every post saying Bitmain is a scam, don't buy from Bitmain etc etc, in this thread. It does NOT prohibit me from saying that in my own threads, if that is what I believe. It also has absolutely no impact on their rating in the Manufacturer trustwothiness thread [in which Bitmain just went down 10 points].

While I have some reservations about that I think overall this is a step in the right direction for Bitmain. Their communication to customers is somewhat lacking. Good luck with the inevitable troll attack.

Hello, needs the S4 a normal C13 cable (like a PC power supply) to power?

Like this:

I ask because Bitmain write 16A and C13 is normaly not rated for 16A.

Yes, judging by the picture it's C13. You'll need a 14GA C13 if running on 120V, or standard 18GA if 240v.

Could someone provide a couple of links to the correct cable needed for the S4?

UK Cable

USA Cable

In case nobody else noticed, their site has conflicting information for the power efficiency.
The miner specs say it is 0.69W/GHS, but their "Never-Ending Progress" picture shows it @ ~0.48W/GHS.

I assume the 0.69W/GHS is the correct value...

And what's with the misleading efficiency chart? The text clearly states that it is .69w/GHs but the chart show .4w/GHs.

The never ending progress picture is misleading because it shows S4 power efficiency coming in at under .5W/GH, but your official specs say the power efficiency is .69W/GH.

BITMAIN why did the graph showing efficiency change and whats with the green dotted line now? 

It was changed based on feedback. The green dotted line represents the unit running @ 1TH.

Is it just me or does this sound like "we priced the S4 so high plus extra shipping to make you buy our cloud instead" ?

AFAIK shipping is at near cost. BTC is low so when people see .4 and .5 charges to ship an 18kg box express around the world they're surprised. 0.4 is only $150.

only one coupon can be used per S4.

This is scam-ish at best.

Same as its always been, prevents abuse. Else it would be buy 7 S2s, get an S4 free. Its meant to be buy S2s, be rewarded for your patronage. You can still sell your other 6 S2 vouchers if you choose to.

very disappointed that bitmain from great company which delivers on time become Preorder company which shows finger to his loyal customers.  but that the old way of doing business. once they got big....screw typical randy...

S4s aren't preorders, these are batches. The L1s are preorders.

Anyone know exactly how loud these will be and whether we can lower the fan speeds?

Bitmain, do you have a decibel reading on the S4 yet? You warn:

* Stable but a little bit noisy

With those large fans and that server psu it appears this is geared more for a Data Center Environment could you please give a decibel reading for those who intend to run a S4 at home to decide if it is reasonable? Thanks.

considering that there is a free or $0.99 apple iphone app that does it-why not post an actual reading?

it will be 70db or more that is why

I'll let you know tomorrow. Its not going to be quiet at stock, but I have a few ideas to get this quieter as the cooling regime isn't quite optimised. Hopefully I can pass this back to the design team.

These new AntMiner S4 units should really kick ass.

It would be helpful if Bitmain actually answered some of the many questions that prospective buyers have asked, instead of just guessing that they "should" kick ass. For example:

Are they still using the old cgminer version? If so, why?

Where is a link to the firmware?

Are these compatible with p2pool?

Plus the many others on this thread. Bitmain are selectively answering only a few of their customers questions whenever they log on, but ignoring most of them.

Come on Bitmain - let's have some answers & support please!!

Bitmain - instead of logging on to announce another batch sale then logging off again, how about answering some questions? I don't want to buy something not knowing if it will work with p2pool or not, or weather it's running old, security vulnerable software or not.

Why don't you answer any questions!!??

Never fear, le dogie is here! I'm going through all questions now, will relay anything I don't know about.

Firmware is running old cgminer for now, being worked on. Will check on P2Pool but I would assume if S3s worked on P2Pool then S4s also would.

Hello all,

Bitmain has employed me to help liaise with the community and later provide technical support. They have done this in order to help provide:

1) timely technical support
2) provide better feedback (if I don't know, I can find out from the people within Bitmain who will)
3) provide product and sales input from you guys directly into the company. If something is going wrong, YOU can fix it
4) provide native English press releases - less ManderEnglish, more sense.

This is a paid position, however it will in no way affect my independence or freedom in being critical towards Bitmain outside of this thread. My contract specifically stipulates:

Quote
Dogie will speak on behalf of BITMAIN and will not criticize BITMAIN in these threads. Dogie still reserves the right to criticize BITMAIN in his other threads. Both parties acknowledge that this relationship has no impact whatsoever on BITMAIN’s rating or standing in “Dogie’s ‘Manufacturer Trustworthiness” thread.

This means I won't sit here and reply to every post saying Bitmain is a scam, don't buy from Bitmain etc etc, in this thread. It does NOT prohibit me from saying that in my own threads, if that is what I believe. It also has absolutely no impact on their rating in the Manufacturer trustwothiness thread [in which Bitmain just went down 10 points].

If you are on a 20A circuit, should you not be using a 12 AWG wire? In which case I can't seem to find anything that would work. I'm in North America, so would I not need a 12 AWG wire with a C13 end and a NEMA 5-20 end?

As far as I can see S4 should not trip a 115V 15A breaker in normal conditions (close to 80%), but if you need a 12 AWG cable and can't find it you can make one... C13 and NEMA 5-20 DIY plugs are available.

I think I'll give it a shot with a 14 AWG cable and make a 12 AWG one in case the first one trips the breaker. Thanks for the help.

Anyone able to find a power cord to use with these? Bitmain says to use one rated for no less than 16A, but I seem to be having trouble finding one to meet those specs.

This one is rated at 125v x 15A so it's over 1,800watts, should work at standard 115v x 16A then.  If you're looking for an extension cord.  Doesn't it come with the power cord?
http://www.amazon.com/gp/product/B0061306C2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

If not, then this will probably work.
http://www.amazon.com/dp/B008DW616O?psc=1

Nope, it doesn't come with a power cord. But thanks for pointing these out!

I wonder why BITMAINTECH is sending S4 without the power cord.

Few reasons
1) there's a wide variety of cord standards worldwide, especially in europe.
2) a lot of people are plugging to PDUS and other specialty wiring, so a cord offers no benefit
3) a cord costs $2-10 depending on type, plus a slight increase in shipping weight. Also makes the package slightly bigger.

I'm fine with no cord, since i plug to a 208v C14, and not the typical 115v north American plug.

ALSO - 15a at 125v is not equal to 16a at 115v. 15a is 15a, and even then you need to have some headroom for 24/7 load. Expect that 1400w will likely trip most 15a breakers, and use a 20a circuit to be safe

If you are on a 20A circuit, should you not be using a 12 AWG wire? In which case I can't seem to find anything that would work. I'm in North America, so would I not need a 12 AWG wire with a C13 end and a NEMA 5-20 end?
