Quick tests. Tried a possible 165 setting:
9x multi (tried 8x too)
Could NOT get into windows. Just wouldn't do it.
So then I backed the fsb down to 270, upd the mult to 10x, and I'm running @ 2700 as we speak.
The trouble is I'm still failing orthos in just a few minutes...
I think my cpu maxes somewhere below 2700, and my board wont do monster fsb'.
