A: If you're on linux, the ATI drivers after 11.6 have a bug that makes them

consume 100% of one CPU core unnecessarily so downgrade to 11.6. If you're on

A: The more aggressively the mining software uses your GPU, the less overclock

|
|
|
+A: Efficiency is defined as the accepted shares returned over the number of
|
|
|
+work items requested. Cgminer generates a lot of work locally, and has a
|
|
|
+buffer of "global" queued work meaning the device may hardly ever be requesting
