but but but the box on my 6950 says it needs a 600W PSU just for it!!!!
It all comes down to the quality of the power supply. A single rail unit also makes a big difference. I'm running 3x5830 cards on a 650w XFX power supply. Single rail unit that is spec'ed at 53 amps on the 12v rail.
this is what came in a sonata II, its probably a dual 12v rail
with the card mining my killawatt reports 230W of power draw. the PSU is probably not the issue unless the card is over amping the rail its on. one of the 6pins is powered via molex adapter
ez. i kill-a-watted my dual 5830s and I was drawing 395W or so... single rail 650 should be fine.
maybe I will try and get a flash drive rolled back to .2a and see if it does any better
5830s in stock at newegg for $109. looks like they have quite a few in stock with a limit of 30 per customer
at sub $9 btc we are touching into speculation territory for miners. you are mining on the prospect of btc being worth more later. that was fine when cpu miners running a single quad could solve a block solo mining, but the power costs of a farm of 5830's vs a single cpu are just nowhere near worth it.
i just jumped a tier in power usage and the cost of Kwhr went to .30$ from .15 this summer.
i'm taking a break from mining till winter.
Just sold my 5850 while it still had some premium value, just running my 6970 + 5870 + 5770 now.
Wow. 30c per Kwhr is up there.
I pay ~10.5c Kwhr. Decided to shut my farm down tonight (13 GPU's). At $10 per BTC it was only making a few bucks a day after electricity cost. Not worth the heat and noise. Now if it was winter time that would be a different story. I could use all this heat then.
Going to start ebaying the cards this weekend.
I am not even sure what I am paying for power right now, its into the summer tiers and it gets a bit convulatued since I am in like usage tier3 at the moment.
hopefulyl it comes down next month, as the home renovation I was doing has slowed and I am not running a ton of extra lights and tools and ramping my AC to like 68F, also july was uber hot
have shut down everything i could to keep costs down including much comforts. at this rate i really wonder why i am still doing this.
Because coins are $11 a pop.
For you GUIMiner guys, are you using phoenix or OpenCL miners?
Got another 6950 for dirt cheap, now I'm thinking of bringing my cards online again for a total of 1.5Ghash/s.
i wonder in the southern US we pay less if we use more? for >1000kwh a month my rate drops, but i'm always over that regardless.
I pay 8.5ct/kwh and I think it's pretty good, definitely still money to be made at >10 a bitcoin, they've gone up to 11+ too, which nice to see.
This thread is TL;DR but has anyone mentioned I0Coins yet?
Should we care about I0Coins?
Saw mention of it at http://i0.btcguild.com/
I have no idea what Ixcoins or IOcoins are but this is all i could find on it https://bitcointalk.org/index.php?topic=36425.0
how much did you get it for? where at? and do they have anymore?... enquiring minds want to know
here's an interesting read... you can now buy bitcoin with cash at any wells fargo or chase bank.
Will they also give you cash for your bitcoins? :rhetorical:
one could only hope..
really tempted to sell most of the coins I've mined at 11
Yep, Lots of people in the same boat. My electric bill for the past month was $600! I sold 3 of my 5830's and still have around 3.5gh online.
I wish my electric bill was $600 last month, since it would mean my earnings from mining were $1800+ (given that cost to produce right now is about 1/3 the value of the coins*)...
http://tvori.info/bitcoin/charts/ is very handy now.
*Based on my electricity costs, cost may vary.
