my guess is, that's a macbook pro mid 2012

but my question is, if you want BTC why not just by the coin
I don't think once the laptop box is open, it still worth as much as you paid for.

thanks.

I guess it's just a defect product and successfully bypass their QA
or maybe a bug walked in and short the circuit

er.........that's not true

I have exactly the same card, actually exactly the same number of cards in my rig, and it's hashing @ 1640 like champs @ 1.013v with significant lower frequency then your Sapphire configuration.  All on risers.
You just need to find those cards sweet spot, it's doable.

the only cons of this card is the fan noise, that kills me
just swap to accelero Xtreme Plus II, and I never see 70C again 

 , nice job

Can't get my wallet sync this morning 

and radiation

copy and add them to your luckycoin.conf, and restart your wallet.

I feel lucky today, I started solo since last night and just dig out my first 588 block this morning right after a normal 88 block

thanks for all your replies

en......have another thought, can I add another 500w e.g Corsair cx500 on top of the 1000w to run the 4 7900 rig?
I mean in terms of wattage this time it should be enough, but is it safe enough to do it this way?

I might have some misinformation that cards, wires, PSU itself get burned because of this kind of setup, so I am a little hesitate

I need to rearrange some of my cards
Currently I am running 3*7950 + 1*7850 on a 1000w platinum psu
and I am thinking to swap out the 7850 and add a 7970 instead

if I undervolt all my cards (they are all working @ 1.05v happily), and put mem clock to insanely low
on a 775 E7200 platform with 1 RAM and 1 SSD

am I pushing the PSU too hard?

It seems the MOUNTING part is missing, which means you can't mount it to any board.
don't take my answer I am just guessing, and I also want to know exactly what's missing

ZWD? Zimbabwean dollar?? or a coin I haven't heard of

try iCoin and make sure all i device can mine the coin

  what?? poop coin, holy....my first read was pop coin, now I smell something different.
anyway, I don't mind if there are still some left

Transfer 2,000,000 to ryantc

Thanks.

errrrrrrrrrrrrr
actually they don't have daymoff on most of the dates you mentioned
the coming one is from June 10-12, and the next one will be
Sep 19-21, and Oct 1-7 annnnnnnnnnd
it's done for year 2013

mathematically correct
but if you factor in space, power consumption and heat dispersion that's a different story.
I guess people like to invest 6500 in miner, they have more faith in BTC success

I observe CoinChoose and Dustcoin for a while and notice that LTC and NVC are usually on par with BTC or sometimes a little premium to BTC, their values are fairly stable ATM.

For other altercoins, they are jumping like clowns, you start to mine some coins show enormous profit and after coins are confirmed its profitability may plunge to only half of BTC, these coins get listed so soon and early adopters dump them once they are listed.

So,
if you want a "diversified portfolio" of coins go with BTC, LTC and NVC
if you want to speculate for enormous profit,  mine coins before they hit any exchange (risky, but yet profitable), it's late when you see it on CoinChoose or Dustcoin IMO

does it come with original retail package and all accessories?
and also do you ship to Canada?

oh, lesson learned, thanks.

so with the current difficult level of 0.0312522, I got 1 block confirmed, 4 orpans and dozens of rejected....
