interesting chip
you should:
A: ) Find a lower RAM strap that works
B: ) Increase FSB term,NB,and Vcore voltage by about .03-5
C
Raise your FSB in 25 Mhz increments until it starts to get unstable..then back off until you can adjust something and get it stable again..
I can tell you this..You don't need a ton of FSB voltage for Kentsfield/Conroe..but you do for Wolfdale/Yorkfield.
1.38v should be good for that chip..
Oh..and PLL voltage, too..Try 1.6-ish 1st..
