Sorry to disappoint but:
- I'm on EU, the first server that was updated
- Having lot of stale shares and submitting them, always accepted (my expire is set way too low, have to set it again to high)
- Producing enough - 670khz per 7950, 91% work unit efficiency
It is just good config. Yes, I can run this card and achieve the same speed on t1, I20, tc 24000, but then I get many rejects, instead I'm using t2, xi4, tc 8192 and works like charm. It is all about optimizing

Not sure why you thought I would be disappointed about anything concerning your configuration, as all I was pointing out was that your observation did not necessarily prove all that you stated it did. What is your MH/s per KWh?
