Turing off? NEVER if breaking even or better each month !! Going to run some hardware until either BTC dies or I do if I am not losing my shirt each month on electricity.
Topic: Who is turning off? (Read 4940 times)
Liquidated 2 * CM1 FPGAs in Nov 12 in preperation for the generation change with ASIC and elec costs in Australia are just rediculous (25ckWh). With the halving and associated rig running costs resulting in a profit of ~$0.37cents per day, I decided the risk was to high hence the liquidation.
CPU + 2 * FPGA + wireless modem + monitor + NAS + cooling fans + power supply efficencies + 2*GPU [6770s @ idle not mining] + MB + HD= 60W+80W+40W+20W+40W+50W+10W+160W+20W+20W= 500Wh = .5*0.25chr*24 = $3 per day just to mine about 0.45BTC = Revenue - Cost = (0.45 * 10 [when BTC=~$10]) - 3 = 1.50 profit per day if running 100% but factoring 75% up rate I experienced = ((0.45 * 10)*.75)-3 =3.375 - 3 = $0.37 profit per day
Now I mine LTC for speculation. This is only done between boot up and when I get back to turn the mining off and start work.
When / If ASICs come out, then I may grab a miner or 2.
Untill this occurs, I will keep aquiring components to finish my hybrid solar / wind stand alone power system whcih will allow me to mine with confidence.

I think undervolting is my task for this weekend. I have 2 rigs, 6 5850s and a 5770 between them. ~2.3gh/s total.
Any idea what an undervolted 5850 will hash at? or what wattage it will pull?

Ah it's been a while since I undervolted 5850s. Start at 0.95V @ 600MHz, and see how high you can raise the clock at those voltages. You should be able to get somewhere around 300MH/s and pull ~100W per card. 5770 is already mediocre enough, but lets assume you don't. That'll give you 1.9GH/s at ~900W.
What about the memory clock? Can you paste the relavant parts of your cgminer here?
My 5870s are picky like that too with the voltage.
My Sapphire 5850 used to mine at 780Mhz 0.85v, about 325Mh/s.
I played with it for a bit last night but can not get the voltage to change. Im using cgminer in BAMT. Used --gpu-vddc .95,.95,1.0,.95 but it wouldnt even start to mine. (5850, 5850, 5770, 5850). Also dropped my clocks to 600, nothing....

I might continue until ASIC's hit.
Payout halved, still making money but now cut in half. I think over the next couple weeks difficultly could actually drop some as GPU's get turned off. Looking at some polls looks like at least 20% are. Network GHash may then drop back down to 18~22 GHash which would drop difficulty and increase my payout some. So who knows what happens. Just keep mining!
I will be cancelling my ASICs from Butterfly labs though.

Turning off my single 7970 miner, leaving on my dual 7970 miner. Fpgas still running of course.

sorry !!! 900 Mh of course.
What GPUs are you using? I'd say you should start undervolting as well! hi, i Tryed it already ...
3*5830 (300 Mh each) when I undervolted i get about 750 Mh with about 400 Watts but crashed sometime during the night ... and losing the saving made ...
will see next year, asic, btc price, ... time are changing

Back on topic:
About 50% of what I make I spend in electric, so Im still in the green. I'll continue mining/heating the house atleast until spring. Depending on the ASIC/difficulty/price I'll decide what to do then.

I'm making 900 gh with 600 watt at the wall ... sadly is europe ..that means BTC = 9.5 euros and power 0.12 ...(more or less heating the room for free)... I hope BTC price goes up soon ...
Nice that you got ASICs already..

I still make a [small] profit on all my rigs.
Even then, I think I will continue to mine for a while.

maybe time to try again bitcoin calculator ?? do you get free power ? or running FPGA
My main mining rig uses 744w and genereates 1.34GH/s. I pay 0.098$ / KWh = 1.75$ a day in electricity. based on current rates, It generates 0.1970 BTC / day * 12.45 = $2.45 less electricity = $0.70 / day.
As long as the exchange rates stay up, I am ok. ~$8.12 / BTC is my cut off point at current difficulty.
Maybe if I get around to under-volting the 4 cards in that rig, I could make even more. I have not been too worried about it yet.
What is that, 4 5850s? Man, idk how you can't be undervolting!
I'll be you your profits will go up. Now I do not have cheap electric (15c/kwh), so undervolting is necessary. If I wasn't undervolting, or it wasn't a 7xxx card, I'd have shut my GPU off by now. I got a undervolted 7970, and I make 630MH/s at 275w (total, for the system, at the wall). Plus my Single at 880 firmware, and I make 1.5Gh/s at ~360W combined between the two. This gives me ~0.2BTC/day, and minus electric it's about $1.40/day.

Mining with halved reward @ 12.60$ pays about as much as it did mining @ 5$, which you all did. The only reason to turn off your rig, before ASIC's arrives, is that you believe that the price gonna tank before your next pool payout. As for the 30TH we are seeing now, it seems that only small miners are shutting down.
Depends on whether you're looking to mine USD or BTC. I hardly looked at the BTCUSD figures.

That's true, but the diff was also 2/3 of what it is today. Back when the price was $3, the diff was barely 2 million.
