Yeah the concept of SLI Crossfire on windows systems and using graph cards like that sparked my interest, especially after I heard about this grad program that used multiple gpu's of PS3's daisy chained together to solve complex algorithms...and then the grad students would play Crysis on the weekends on full power and not crash. Got me thinking about two graph cards. Looked into it and seems to be slim info.

As far as pools go, are some better than others? Is success and speed determined by the number of users?

Well, from what I understood, the mac pro (intel) can only run a card that has flashed bios to run on a mac, or a card direct from apple.com. But even in the flashed bios card community I can't find anything on multiple cards.

Running a mac pro on snow leopard 10.6.6 with an Nvidia Geforce8800GT.

Anyone know anything about running multiple graphics cards in the mac pro? Google isn't telling me a whole lot.

Worked like a charm. You're a lifesaver man. Thanks. The only thing I'm unclear on is the login. Would I use my login to the mining pool site? to this site? which login?

went here:
https://github.com/Diablo-D3/DiabloMiner

downloaded the link 'DiabloMiner-OSX.sh" opened it up. dragged into a terminal. and I get that error message.

yeah......not here to play fanboy. Just want an answer to a question.

Hi All,

Lets first assume I know nothing about anything.
I run a mac pro on Snow Leopard 10.6.6 and have an Nvidia GeForce 8800GT card.
I am attempting to get DiabloMiner up and running, join a mining pool and mine.

At this point in time I have attempted to run the DiabloMiner-OSX.sh file in terminal. And I am met with this message:

fifths-mac-pro:~ Fifth$ /DiabloMiner-OSX.sh
Exception in thread "main" java.lang.NoClassDefFoundError: com/diablominer/DiabloMiner/DiabloMiner

From what I can see (googled the error message) this is a fairly common error message. Yet I can only find it displayed here:

The question of 'what the heck is this and why is it doing it' is dignified a few times but the process to fix it is not explained in a method or using language I personally am familiar with. Would anyone help me out here?
