Ye its a bit strange to try to explain thats why I said my DK gets a bit "funky" sometimes it works sometimes it doesn't & the "FSB Grand Canyon" to coin your great phrase moves depending on the way the board is setup, voltages, divider etc all make a difference.

The only 2 fsb's that don't run on my UT are 467 & 487 so I just jump them.

486fsb looks to be the max I can hold prime blend stable before my board/setup locks up. The q9650 chip will small prime 500fsb, it would be interesting to know how you get on.
