im using windows 7. all 4 cards are detected in device manager and afterburner. only 4 cores are mining with cgminer. when i run 1 card i still only get 1 core. i tried CCC 12.3 and 11.12. any ideas what the problem is?
Make sure you back up your wallet regularly! Unlike a bank account, nobody can help you if you lose access to your BTC.

Are you running 32-bit or 64-bit?
