Righto, thanks. I doubt anyone goes out of their way to trust my opinions, but I really like Bitmain gear (for disclosure, I own about 15 undervolted S1, run an S2 Kit and an S3) and I can't recommend the S5 until I trust a few things have been taken care of. It'd be really nice to have gotten ahold of one of those evaluation units, but then a thousand other people could say the same thing.

the big fear is will behave like Asic Miner"s tube or prisma.  

I owned both of them and both   had current/heat runaway problems. very hard to keep stable.

 Once I get the test module I can

A) undervolt it with 1 psu.

B) over volt it with another psu.

C) volt it perfectly with a high quality psu.

D) sent 11 volts to one board and 13 volts to the other board. using 2 different psu's

E)Set a low freq

F) set a high freq

G) add the higher quality silverstone fan for cooling

The s-1 and s-3's I have had were all good or very good. 1 dead ethernet and all else good out of 30-35 units.

I have read problems on the s-2 the s-4 the c-1 but I never had one of them to test



I own quite a bit of Bitmain gear, and I can say with confidence they will not make gear as bad as Asic Miner makes..

S4's catching fire. My Asic Miners (not the prisma line) are more reliable and less smokey. Point being, each brand has it's issues and they all go through various stages. The exception seems to be spondoolies as they are clearly frontrunners.

Just over a year ago, Bitmain released its ground-breaking Antminer S1 to the market. Miners no longer had to sacrifice space, noise levels and hashing power in order to mine. The S1 became the staple of the home miner, before being upgraded to the Antminer S3 7 months later.

Today, Bitmain is proud to announce its 3rd generation chip in conjunction with its 9th product: the Antminer S5. It is 450 USD 418 USD per unit (excluding shipping) and will ship starting on December 27th.


Coupons for S4's can they be converted to S5's?

Sorry if this was asked and answered already.

not yet, but who knows, maybe they will allow at least S3/C1 coupons in the last minute.

Please keep in mind people, this is Bitmain's product discussion thread. While excessive harassing of members isn't acceptable under any circumstance, it is especially not acceptable in someone else's thread. I'm sure Dogie doesn't mind talking to reasonable people about whatever issues people are having with him, but please do not do it here. Don't clutter the thread making information harder to access for those that want it.

SaltySpitoon,

Firstly, thank you for your input.

However, if I am to be accused of something I have not done on a Bitmain thread, by someone who is paid by Bitmain - I believe I am, at the very least, entitled to an apology. Is that so unreasonable? I think not. I'm sure that you have read the circumstances of my request in this thread - if it were to happen to yourself, would you not want an apology? As genuine & appreciated as BitmainWarranty's & Yoshi's apology was, it's not the same, and until dogie realises the errors of his ways, the situation will continue & indeed probably get worse - weather it is with me or any of the other forum members he's seen fit to abuse or insult on Bitmain threads. It has gone too far already - & needs to be nipped at the bud.

Sorry, but my request still stands.

Exactly!

When the defenders of the dastardly run their mouths, they are indeed condoning his abhorrent behaviour.

Notice how they are happy to change & avoid the subject when its proven beyond a doubt that he/they are in the wrong.

Shilling at its finest - and lamest.





You are using a broad net with your accusation. Perhaps you should focus your energy towards getting your grievances remedied.

Sadly at some point there are people in this world that are not worth spending time and energy on. As you can see, many here have meet these people and are done wasting our lives with them. The only solution is to make others aware of this problem. We are done with condescending and terse replies from people like Dogie and others.

Yes maybe donate all your coupons and get a few S5 coupons? Or some such trade up?

Actually want to upgrade the S2s we got to S5s keep the same or a little more hash at half the power sorta plan.

The coupons are a way to get rid of stock. With the S5 they have probably scaled production to the current climate. So it is unlikely that they will issue S5 coupons (no point in allowing s3/s4/c1 coupons. It's just numbers in a machine so it will be easier to create dedicated ones) anytime soon, if ever (the S5 looks like a short pit stop on the way to 14/16nm).

I doubt that just by the sheer numbers of them I received (coupons).  Plus if they really wanted to move them, they would continue to lower the price.  AFAIK, the price hasn't changed since the coupons came out.  That's why I quit buying the S4. Even though they were loud, they were a set and forget miner.

I would say the massive amount of coupons bitman was giving away was a way for them to clear out their inventory. I had contacted them asking for coupons and they responded by asking if I would be willing to buy ~4x as many S4s as I had asked for coupons.

They probably were anticipating that more efficient miners would be released soon (for example the s5) which would result in lower selling prices for their machines. Also giving away coupons like this means that their customers can have the physiological feeling that they are getting a good deal

I think this one may be one to use. It will adjust down to 9.5v at 36A. http://www.ebay.com/itm/DC-Power-Supply-Adj-Volts-9-5-Up-To-15-VDC-36A-12-03-/371222321916? Have not had to use these PSU's since I got rid of the USB miners. But the undervolting of the S5 is why I bought one to try and may replace all my S3's with it.
yes and I linked a buy it now above 69 dollars
http://www.ebay.com/itm/400-Watt-9-15-DC-Volts-Adjustable-36-Amp-Power-Supply-Real-USA-MegaWatt-/180777051248?pt=LH_DefaultDomain_0&hash=item2a1726e470

problem is its rated at 30A for a 100% duty cycle (like bitcoin mining is) so the S5 would pull more power than is available for most voltages. Bitmain says that 10A+ will be sufficient for 9V but i imagine that only applies to a single blade

12v/14 chips = 0.86V (stock is 0.8V?)
10v/14 chips = 0.71V or ~0.34w/GH or ~780Gh = 265W (26.5 A)
9v/14 chips = 0.64V or ~0.26w/GH or ~560Gh = 145.6W (16 A)   

plus, at 9V draw, the linked power supply is likely <~85% efficient so youll be drawing more power at the wall

And if the price of xbt skyrockets they can let the coupons expire without being accused of hiking prices.

plus, at 9V draw, the linked power supply is likely <~85% efficient so youll be drawing more power at the wall

  yeah I found I have enough on hand to fully test this.

 I advise no one to try it if they do not have the psu in hand.  If I recall the 2 psu's I found are only 80% so savings are not much power wise.    9/12  volts is 75 percent less   but an 80 percent power supply vs a 92% atx loses a lot of power

example  600 watts x .75 = 450 watts / .8 = 562 watts

vs  600 watts / .92 =  652 watts.

 So  the savings of 150 watts  because  volt reduction of  reduces to  savings of 90 watts due to the psu lacking good efficiency .

I will do testing because  I have spoken with a member about an adapter for a psu like the evga 1300 g2.  It would make the psu maybe go from 92 % to 87 %   and give the same volt reduction to  9 volts..

This translates to 450 watts/ .87 =  517 watts   
 
which is  better then the 562 watts possible  with the cheap megawatt psu's

All of this is theory  not tested.  So I advise  all to delay buying the megawatt psu's for just a bit of time.

It seems that the 30A for 100% duty cycle will be sufficient if the miner will only pull 16amps at 9v?

i couldnt have put it any better myself.

6 months of being fkd around over a grand is more than enough time to waste .

i know now that bitmain will lie, twist, promise & deny any and all he chooses to, to save a few pennies.

hes a typical stingy, crooked penny-pinching liar.

and the turds he employs are either fully aware of this and dont care or are ignorant and willfully so.

all that is left to do is to warn others as often as i feel like doing so.

anything less than actual compensation is a waste of my time & energy as im not getting paid to annoy/lie/confuse people.

not that i would lower myself into such a role.

dogie & his wannabe gang of timewatster shillettes deserve all they have brought upon themselves and more.

I think this one may be one to use. It will adjust down to 9.5v at 36A. http://www.ebay.com/itm/DC-Power-Supply-Adj-Volts-9-5-Up-To-15-VDC-36A-12-03-/371222321916? Have not had to use these PSU's since I got rid of the USB miners. But the undervolting of the S5 is why I bought one to try and may replace all my S3's with it.
yes and I linked a buy it now above 69 dollars
http://www.ebay.com/itm/400-Watt-9-15-DC-Volts-Adjustable-36-Amp-Power-Supply-Real-USA-MegaWatt-/180777051248?pt=LH_DefaultDomain_0&hash=item2a1726e470

problem is its rated at 30A for a 100% duty cycle (like bitcoin mining is) so the S5 would pull more power than is available for most voltages. Bitmain says that 10A+ will be sufficient for 9V but i imagine that only applies to a single blade

12v/14 chips = 0.86V (stock is 0.8V?)
10v/14 chips = 0.71V or ~0.34w/GH or ~780Gh = 265W (26.5 A)
9v/14 chips = 0.64V or ~0.26w/GH or ~560Gh = 145.6W (16 A)  

plus, at 9V draw, the linked power supply is likely <~85% efficient so youll be drawing more power at the wall

 yeah I found I have enough on hand to fully test this.

 I advise no one to try it if they do not have the psu in hand.  If I recall the 2 psu's I found are only 80% so savings are not much power wise.    9/12  volts is 75 percent less   but an 80 percent power supply vs a 92% atx loses a lot of power

example  600 watts x .75 = 450 watts / .8 = 562 watts

vs  600 watts / .92 =  652 watts.

 So  the savings of 150 watts  because  volt reduction of  reduces to  savings of 90 watts due to the psu lacking good efficiency .

I will do testing because  I have spoken with a member about an adapter for a psu like the evga 1300 g2.  It would make the psu maybe go from 92 % to 87 %   and give the same volt reduction to  9 volts..

This translates to 450 watts/ .87 =  517 watts    
 
which is  better then the 562 watts possible  with the cheap megawatt psu's

All of this is theory  not tested.  So I advise  all to delay buying the megawatt psu's for just a bit of time.

So what's all the hoo haa about 0.2j/GH?

these are all possible down clock ideas.  

the s-1 went from 180gh to 140gh  and from 360 watts to  170 watts  or 2 watts a gh to 1.2 watts

so if the ideas being tossed about can work ..

we may go from 1100 gh and 600 watts = .54  per gh to   950 gh and 400 watts =  .42 per gh

OK. Sorry, I skipped a couple of beats. Now I see the 9v 0.26w/GH @ 560GH.

Carry on
