Ohhh also, check your port on pooledbits for what it's showing on the website. I was mining for like 2 hours on the wrong port. My miner was showing everything normal but the website wasn't registering my speed. Switched the port and boom, instant speed correlation. I'm still pissed about my lack of payouts.

For my 1 day 18 hours of mining with them I have 927,000 shares with 31 diff. I'm averaging 430Kh/s. about 28,000 accepts and 785 rejects. So 2.8% rejects, 90% of those right after it finds a new block and the first is "previous-hash" so I'm guessing that's normal.
