[Antminer S1 Sales open] Price changes daily, now 0.414 BTC for 180GH/s

[GenTarkin]

right on the money, thats an increase of 55w per unit... and thats pretty damn close to the 50mhz increase
Weird, my seasonic 750watt capstone ... does that at 120v =)
Guess its just as efficient at 120 as it is at 240

These antminers increase in power consumption proportional to the mhz increase. Linear or w/e the term is...

Whereas its not until u increase voltage of the chips that power consumption rises exponentially.

Rosewill Capstone? I'm pretty sure those are Super Flower units, not Seasonic. Very nice PSUs though.

Ah, sorry my bad, yeah I got the brands mixed up in my head. Yes, its a rosewill capstone.
My most recent PSU is a seasonic 650w gold

Have anyone tried to underclock this miners? I wonder how low can we get the J/GH number and at what cost in hashrate terms.

Probably 1J/GH, if you're willing to accept half the hashrate. I plan to change the voltage on one of mine and see the effect. I'll probably first go to 1.05V and see if I can keep it stable at 400MHz, and then go down from there.

gonna post a guide on this mod? isnt it switching out like one resistor on each "module"(4 per blade) to change the voltage?

OK, so I guess I shouldn't worry about my miner as I have it on a 500w PSU.

Thanks guys

My S1 is using 430w but that's overclocked.  I would be more interested in the temperature than the speed itself, which will vary somewhat.  Mine is running @ 44 both sides, again that's clocked.  I did install a fan on the front side which seems to make a big difference.

Happy Mining!

I thought i would share this:::

<jimbit_> oK,.. heres a good one..
<jimbit_> the kill a watts we use to measure wattage.... they WILL work on 220.
<jimbit_> I just plugged  mine into 220 and plugged the seasonic 750 into it with 2 antminers on it
<jimbit_> 686 watts  3.16 amps

edit:  after running for a few.. it is 689 watts.  If what everyone is saying about 440watts to OC for 20 Gh... it is NOT worth it.. not even close.
100 watts for 20Gh....


edit:  i thought I would add... this is on a 12/3 wire that is at least 100 feet from the panel

I am not surprised it is not seeming efficient your PSU is running at 91.5%

Naw, its not running at 91.5% ... the 686w is wall reading...

Doh! Your right...too early in the morning, I need more coffee

I suppose I could. If I'm really ambitious I might make a shmoo plot, but I'm not sure I'll get that far.
I'm gone for a couple weeks though, so it won't be any time soon.
You want to change R3, R66, R38 and R52. The default is 8.2kOhm. The exact formula as per the datasheet is a little hairy as it depends on a lot of terms, but you can probably just simplify it to R = 16266*Vout - 9.76kOhm

Just quick one. Coupons- they works per order or i can use 2,3 coupons on one order?

You can use more than one per order i believe.

To clarify, just one per item in the order. So to use more than one coupon you have to buy more than one item.

No you can use 2 or 3 on one item - there is a drop down that lets you choose.

And when you do so it tells you you can't use more than one coupon per item ordered.

Say you have one Antminer in your cart, you go to checkout and you add your coupon for 0.02BTC, then you change the dropown to change it to 2 coupons. It then says in red at the top of the page:

You can use one coupon per product

THen it is either a bug in their code or they changed their rules.

Ever since Ive ordered with coupons...its always been just 1 coupon per product..

voltage is key for heat..... and of course power efficiency..  my scrypt rigs get about 2.5kh per watt by lowering voltage.

That being said.. I am not changing the hardware to change the voltage.. would be nice if it could be done thru cgminer.  come summer time I like being able to turn down all rigs thru my webmon interface when it gets too hot...

Ur not changing the hardware?!?....what are you doing  the "pencil trick" or something?

What I am saying is, if changing voltage requires switching out resistors or something.. i will just live with it at stock volts..

I have a simple question:

S1 purchased before 8th of this month will be shipped all together after 8th ?

Bitmain has not said anything for a while but no way in my eyes can they post backdated order almost 500 to 1000+ orders in 1 day.

Plus they have Sushi order to deal with, unless they have an army of workers working round the clock during china holiday then I see some orders will not be shipped till mid week.

I would take my hat off to Bitmain and his team if they ship that many orders in 1 day. I would love to see UPS face off driver collection the orders. His van would be ridding  low

Does anyone know when Bitmain will be back?

I just made another order. I hope they will not stuck in mumbai again.

This will be the UPS man when coming back from Bitmain factory

Your photo looks more like sushi or bitmain people going to UPS office to send our units.
