BOINC shows wrong times for first tests... It is 20+ minutes... But it would take 3 hours as I see | |

That's the beauty of BOINC, it automatically adjusts generic estimates to be more accurate to your PC. That being said, I've increased estimates for future WUs, because it hasn't been done since we reached the jump in FFT processing duration.

yes, but for challenge people can get too many WUs, if time is wrong :) | |

That's why we are also imposing a limit on the amount of WUs you can have at any time - we've learnt that from the previous challenges :)

What is a rough guess to complete a work unit on a core2 2.4GHz cpu? I have not done 321 and was wondering how long each one takes.

My 2,66GHz core2 Quad (WinXP32) used approx. 168 minutes.

You are right Sorry was looking on a lower n value.

Turn HT on, redo the tests, it would be interesting to see.
