Did you read my post? I'm assuming when you write MHZ, you really mean MH/s. First, we were trying to find the most profitable settings, surprisingly as you overclock, while you're MH/s increases, often your MH/j tends to decrease, meaning while you get more BTC, it costs you more per BTC to generate them.
Yes I did read your post and yes I did mean Mh/s. If you're just talking about profitability then why did you specifically say that Linux was far faster than Windows? Did your testing show Linux to have a greater hash rate or not?
