So what you doing?
been lots of speculation
would be interesting to see some numbers from miners
I plan to continue my GPUs and Fpga's till ASICS arrive
Cheers

I'm still trying to decide is the $0.40 a day (after costs) is worth the wear and tear on my GPU. Of course I'll still mine with my Single Until ASICs hit.

Wheres the option Yes I'll be turning off (gpu's) and keep on mining (fpgas) ?

I guess I aimed the question more at GPU mining, assuming FPGA would continue as they are cheaper to run :)
and I have had 50hundered dozen other options I could have included offered to me ;)

I stopped mining back in August...figured I might as well get my moneys worth on my GPUs

2.5Gh went out of the door !

Will be a cold winter  :-\

I'll definitely not be mining during the warm summer months now.  It would cost too much to keep the heat down with air conditioning, would be cheaper overall to not mine during those months for me.

Voted, still bebating as with the current price the short term slight gain is not worth my time.  But what if the USD value per bitcoin rises?  I full expect that to happen, but I also miss my beast of a gaming rig with Tri-fire 7970's.  It's got a 4th card packed in now (5970) just for mining.

I want to support bitcoin and ozcoin (been some issues but nothing but honesty and work to resolve from the team)  but still...


So, I setup a full bitcoin node today.  I think that is the next best thing if I shut down my miners until my ASIC's arrive.  Though I kinda want to keep them going till they do...but I will not wait more then a month with my 4.5GH total.

I just got started really a month ago so I plan on keeping running my small-time game here with low to no electricity costs.  I like the idea of continuing to add to the ecosystem in general.

Thanks for the responses :)
even with the relatively small sample the numbers are roughly what I would expect
cheers

I'm going to mine my GPU's till the last fan bearing.  Just kinda funny that way.

successfully reinstalled all mashines, and now mining ltc.. but dont know how long it can be useful because of diff...

Got more ram and switched some gpus to litecoin and some to pppcoin. fpgas are still on bitcoin.

Not turning anything off until I start loosing profit. Will keep running even if I'm making $101 for every $100 I spend in electricity. Will be switching all of my GPUs to LTC if it's more profitable.

As soon as I hit the 0.10 BTC payout threshold on BTCGuild I'm stopping, some time today.
The combination of increasing difficulty and the halving have taken a toll on my 200 Mh/s "rig"  8)

Since I'm a software engineer I see this as my opportunity to switch over to solving a few interesting problems in OpenCL, something I've always found interesting.

TRC solo maybe while I find a local gamer to buy a few cards. Then buy an asic preorder to get my foot in the door properly this time :).

Well hopefully anyway.

I'll ponder it while im throwing benjamins at the local vegas economy this weekend! Well needed  ;D

If you want to stop mining but still contribute to the Bitcoin network, running a node on a decently powered machine is a good way to do that. The network doesn't only need megahashes, it needs sockets!

People are turning off !!!

We lose about 20% hash rate on pools since yesterday ...

I'm living in a cold country ... I use my rid to heat the room ...producing coins just cover the power cost ...

If coin price stays in this range, I will power off next summer.

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 ???

It's called undervolting. Right now I can make ~30-40 cents a day. Not a lot, and I'm thinking the $8 between now and the new year just isn't worth it.

However, worth be damned. Profit be damned. I believe in BTC, and I just like the idea of converting electricity into coins, so I'm gonna keep it going anyways.

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.

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.

Depends on whether you're looking to mine USD or BTC.  I hardly looked at the BTCUSD figures.

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!  :o 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.

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..

sorry !!! 900 Mh of course.

What GPUs are you using? I'd say you should start undervolting as well!

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?


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.

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

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.

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

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. 

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....

My 5870s are picky like that too with the voltage.

What about the memory clock? Can you paste the relavant parts of your cgminer here?

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.

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.
