They'll be like gift cards for retail stores, away for stores to sell stuff without selling anything and if amazon goes bankrupt they'll be worthless..

the price dropped quite sharply and there were a lot of sells from about 115 to 105, I'm surprised the price has held so well..

hmm official mt gox press release suggests this may be something else entirely. price is rebounding...

It's already started http://betabeat.com/2013/05/department-of-homeland-security-shuts-down-dwolla-payments-to-and-from-mt-gox/ Might be a buying opportunity for those with funds in the right place.

Interesting ars technica article on the benefits of other cryptos besides bitcoin http://arstechnica.com/business/2013/05/wary-of-bitcoin-a-guide-to-some-other-cryptocurrencies/

Might try flashing the other card and see if power usage drops another 70w!

yeah slipage, that's the same version I used. power usage for the one card dropped 70w that is insane! I don't know what they did with that new bios version but it was very silly by the look of it. still running fine at 1ghz... just using less power now.

Back to mining bitcoin as the litecoin difficulty has sky rocketed overnight. Learning more about mining, I was having trouble with a configuration so I replaced one of the cards with a model I thought would work better. two things. gpu-z can help you monitor the temperature of your VRM's...

looks like the butterfly labs products are real! http://arstechnica.com/gadgets/2013/05/weve-got-a-butterfly-labs-bitcoin-miner-and-its-pretty-darn-fast/

I imagine it should be number of blocks in the chain * payout ? I have a feeling that chinacoin might be around for a while, don't underestimate nationalism...

Hmmm A new crypto currency has popped up called BBQcoin, is that you retarded monkey?

Ah i've been having the same problems with 7870's (MSI) i spent a good 3 hours playing around with settings but couldn't get them to provide any decent number of hashes for scrypt mining. What I did manage to do is tune them so they were producing hardly any heat... not ideal but at least that...

you don't need to set shaders if you are using thread concurrency. also I'm getting about ~600 on stock 1ghz clock so at 1200 that is probably right

fantastic =) what were your final settings?

You shouldn't bother with shaders if you are using thread-concurrency. Also based on my previously experiments you should try setting the thread concurrency to 64 * bus bandwidth (384) just try and even 24000 and see how it goes, (then try increasing the intensity until you get errors) also...

You;ll have to start getting creative with your cooling when you start putting more cards in, also you should be aiming to run your PSU at 70-80% as that is where it is most efficient.

It's only one card, I mean gigabyte makes two models of card.

that gets me 605 kh/s There are 2 7950's though, I've got the gv-r795wf3-3gd revision 2 model I also updated the firmware (which you shouldn't need to do)
