Here's some questions from me:
1)Have you set up an account with the smaller pools?(I know this sounds like I'm assuming your an idiot but every makes mistakes
[There have been plenty of times when my computer won't turn on because the power switch was off])
2)Could you post the command line for the smaller pool?
3)Are you running any odd programs in the background such as TOR?
4)Could you list the settings and flags you are using?
5)When are you getting your graphics cards(or have you not ordered them yet) because it's a whole lot simpler just to test the real deal.
P.S. If I end up helping you I would much appreciate a few bitcents.(I will do all I can to help you whether or not you tip me.)
