So, pooled mining has become a pretty common and smooth operation, and I certainly enjoy it. But I've picked up a few pieces of hardware and based on rough calculations it seems like in theory it should be more profitable if I were to go solo, but this all relies on calculations using Hash/sec values of a bunch of cards combined.

So my question is, how do you set all your rigs to collectively work on a single block?

Or am I misunderstanding how the whole process works?
