PSU is a MasterCooler 1000, so that's not the issue I wouldn't think.

Right now I have 1GB ram, a 5850 and 5870 with the crossfire ribbon.  The computer sees both cards.  GUIMiner sees both cards (the 5850 is device 0 and 5870 is device 1).  Ultimately, I'd like to run both my 5850's and the 5870 all at the same time.

GUIMiner will run either card without a problem.  The problem is when I start to run both cards at the same time.  The second card being run will immediately crash and drop down to 3Mhps or so while the first keeps running.

Bump with 2 BTC reward.

When I finally got XP to recognize them both, I ran GUIMiner.  Device 0 ran fine.  Device 1, after being started, with the same settings, crashes the drivers.  I have the latest CCC and all that that entails.  I am running them Crossfire because I only have 1 monitor.

Will using the dummy plugs help?  Do I need different drivers?

I have a 5870 waiting to be used as well, but I want at least these identical cards to work together before tackling that.

The government will be many years behind Bitcoin.  However, why can't they simply start mining for themselves?  Over time, they can simply process transaction fees, when means they will essentially be collecting taxes on transactions.

Would this work?  Set up a service wherein people create accounts and deposit BTC, like a bank.  They submit two things to the service.  A PIN of their choosing and a scan of their fingerprint.

Merchants have a register and a fingerprint scanner than can access the bank.  If sale price is 1BTC, you simply key in your PIN (so the service doesn't need to search all fingerprints in the database, only those with that same PIN) and scan your fingerprint.  When the system matches the fingerprint to the PIN, they send the BTC to the merchant.  Now you have a transaction with no cash and no card.  Only a number in the buyer's head and a finger on his hand.

Why is it that everyone assumes the $:BTC ratio will always be $7.00?  If the price on MTGOX goes to $70.00, mining would be as profitable as ever.

I think you're naming in the wrong direction.  Should the rate of acceptance or exchange grow from here to respectible levels (10,000 dollars per coin or 30% of the world population using BTC), you don't need to worry about what you'll call 1 million BTC.  It will simply be 1 million BTC.  We don't say megadollars.

You'd need to figure out how to name 0.001BTC all the way down to 0.000001BTC.

So my 1,000 dollar 1Ghs system isn't a total waste.  Fwwweeewww.

FPGAMiner, what else would explain the difficulty jump?  I'm thinking I ordered my 5850's at exactly the wrong time.

You and I have the exact same problem.

I am trying to set up my computer so that it will be ready to go when my 2 video cards arrive.  There are 2 problems.  The first one is trivial and I suspect it will be resolved very quickly.

My batch line is as follows... start /DC:\rpcminer\rpcminer-cpu -url=http://mining.bitcoin.cz:8332 -user=***.*** -pass=***

When I type it into the command prompt, the program opens and runs.  When I try to use the batch file, a Windows error pops up saying Windows cannot find "-url=http://mining.bitcoin.cz:8332".  What gives?  I'm using Windows 7 64bit.

Second, when the programs runs, it says that I cannot establish a connection with RPC.  Even with all the ports open and forwarded, all firewalls turned off, I still get this error.  My Bitcoin client works fine, but I would like to join a pool when my cards arrive in a few days.

If I use a port checker, it tells me the ports are closed.  Even if I set it up to look for localhost on that port, it won't find it.

Can you help?
