Was soloing for 48 hr, found 2 blocks.  First block within 3 hr, then another about 14hr in.

Just changed to ypool and within 3 min found a block.  "Lucky" me.  Gonna let it run for a couple days there and see how much I can rack up. 

4x 280x at about 22CPD.  Not overclocking or anything, using v10.1.
