looks like my Yorkie, QX9650, working at 63% GTL REF, is limited to 480 FSB to function within windows...Prime 95 is going on right now at 63% GTL REF...doing nicely after 30 minutes...at 490 FSB (same multi, 8x) it would freeze or drop 1 or 2 cores out after 5 minutes.

It doesn't really make much sense to me that they would have different values by default. Why would one die be set to .63 and the other to .67? I'm able to run for 7 hours at 490 with both at .67, at which point one core fails prime. The other 3 were still running FFTs at the 10 hour mark.
