why is everyone talking about how much watts such and such pulls?  that isn't most efficient

most efficient is what makes you the most money

sometimes i get the feeling that at least a good quarter of the people here get x amt of dollars a month and think theyre making a profit, even though their electricity costs + equipment depreciation is 2x

Because as a GUIDELINE, 10MHs/W will be more profitable than 1MHs/W. I'm sure you know this, so please stop nitpicking.

what?

90% or more of the posts in this thread are listing better efficiency by lowering overall output

where is this guideline you speak of?

I am pretty sure the guideline he speaks of is common sense.   10 is better then 1 if your looking for more of something.
what?

10 apples is better than 1 apple, yes.

So one bawzz super elite 200wpm typist costs you $20 an hour to employ as a medical transcriptionist... you can outsource to India and employ four 100wpm typists there for same price.    first is more efficient, second gets you more money

Both of your analogies doen't make any sense, because that's not what ANYONE in this thread is posting. Almost everyone in here is posting (total product gained / total cost of obtaining product), which, in your annalogy, would be wpm/$. 200wpm/$20 (one uber typist) is 10wpm/$. 400wpm/$20 (4 typist at same money) gets you 20wpm/$. Second is more efficient, AND gets you more money. See the correlation? The two are the same. In our case, we're dealing with MHs/W, instead of wpm/$.

Also, 10 apples are better than 1. Yes. However, buying 10 apples per $ is more cost EFFICIENT than 1 apple per $, which is exactly what mining efficiency is all about.

Just got a kill-a-watt and measured my usage.  860w, with an average around 8,552 mh.  So it's about 9.94 mh/w Cheesy

10 BFLs running off of a corsair ax1200
Mac Mini Server

And this is while cpu mining for litecoin as well (35 kh).

No more mining for me.  I make roughly 1850 MH/s worth of BTC per week now, @ 0 Watts.  Suck it, FPGA/ASICs Tongue

Investing heavily?

2x BFL singles

155W
1650MH/s

10.6MH/W Cheesy

Am I not welcome here anymore?

I thought each BFL was 80W each...how is your system less than 160?

i did a killawatt on the bfl's when i first go tthem.  it was under80.   

Thanks. What firmware was that running?

I also found this thread by P_shep. It appears he's using an ATX PSU to power the Singles, which is more efficient.

firmware..?  no idea.  got them hashing, left them alone. as long as the heat is under 59C they get 826Mh each (2)

I am waiting on cables from : https://bitcointalksearch.org/topic/wts-atx-psu-to-25-or-2155mm-12v-coaxial-plug-power-cables-new-product-74397

You go around adding BFLs and video cards to everything you can touch, don't you yochdog. lol

on of my rigs:

4,600 MH/s

955 Watts at the wall

4.81 MH/w



3x BFL singles
2X 7970

I run dual hex-core XEONS, so that takes the efficiency waaaaay down.  

the 7970's are dialed in at 3.08 MH/w though....which is awesome.

Sorry if this is a stupid question, but I've only ever mined with 58xx cards. Why do your memory speeds seem so high? Do 79xx cards not like lower mem clocks? I'll be getting one in the near future, so that's why i'm asking.

Afterburner wont let me set the memory clocks lower.

Anyways I believe memory is power-gated on the 7970 when not in use, because I could not find any power consumption difference while mining between 685 MHz @ 1.5V and 1700 MHz @ 1.7V.
