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

[flipNstack]

antminer oc'd to 400mhz runs fairly stable at about 203GHs with temps in the low forties, fanspeed at 2800rpm,  HW errors about .1% and CPU about 100%

when i lower the freq to 387.5mhz it looses about 6GH, HW=0 (never changes) and saves about 10W,  but everything else stays the same.

i know its not a big difference either way but which is more preferable considering my circumstances.  Im thinking considering the difficulty increases comming, hell with the 10W and to push it as much as possible, but its the HW thing which is making me hesitate.

ive also seen others discuss the cpu bottleneck when overclocking but no real solutions.  is there a way to ease the cpu usage and does it matter?

Hi. Need help. My ant shipped EMS.
1 February 2014 09:58:21 — sent to the customs control.
The item is held by customs. The reason is: CONFIRMATION VALUE attachments
It keeps in custom-house

ruh roh...

tell them its a repaired unit, maybe

The pool reported hashrate is what ultimately matters, as it's what defines your payout. So don't mind the HW errors, overclock it to 400 MHz.

Bitmain, any price protection on the next batch of orders?

[wpgdeez]

Yeah it's silly. Set up a p2pool node or join a public p2pool node. Or join some other smaller pool.

Variance is too risky with the rate of difficulty increase to use a smaller pool.

Variance isn't "risk", just variance in when you get paid. You won't make less income on a smaller pool. You'll just get larger payouts less often, instead of on a big pool where you get tiny payouts very often.

You will get less coins if the difficulty has a massive jump while you are still churning through an old block on your slow ass pool.

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.

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

Why don't you overclock it and see for yourself instead of reading what everyone is saying.

HA.. good point... but even 50 more watts will not be worth 20Gh  ....  now it has settled down to a solid 680...  so each ant is 340 stock at 220v

edit:  actually that is wrong.. 50watts would be OK. cause that is not much more then the stock gh/watt

50 more watts for 20 GH/s is only 2.5J/GH. That's only a bit above the normal value of 2J/GH, and will earn way more in income than it costs in power.

Interesting on the KillAWatt. I've never tried it but I always wondered if it might. Never got around to making a cheater though. I'll have to give it a try now.

Had 4 units at 400Mhz consuming 1740w. Tried to lower to 375Mhz - got 1640w. This antminer group is not really that efficient as every miner runs off a regular consumer PSU. So about 100w difference for 40Ghs.

Been running for 40 minutes only so bit early to tell but really low HW errors so far. Not that it really matter sI guess as my worst behaving antminer had 0.9% on 400Mhz. They do run just about as hot.

[GenTarkin]

Obviously some of are you are complete noobs and havent read my previous power readouts.
I have a gold PSU on 120V, antminers @ 400mhz use just 400w....
These things are roughly 1w / 1mhz....simple as that, if you are getting 440w then ur PSU SUCKS!

I took the advice and overclocked the 2 rigs with the kill a watt...

2 ants 350 freq  686 watts   358 gh
2 ants 400 freq  777 watts   400+gh


this is on a seasonic 750 on 220v: 

[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.

[mutex]

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.
