You technically CANNOT solo mine, at least on your own machine. You could however solo mine on a private pool, but that isn't the greatest idea. You'll get more out of using a public pool like blockeater(.tk) unimining.net, or another pool. Unimining is pretty set on hashing power I think though
There are other smaller pools out there that could use more hashing power. *cough* blockeater *cough cough cough*
