i'm having trouble reaching 500fsb on a q9650. right now i'm at 490 and i can't get the last few mhz in. i suspect that it's my memory not letting me go higher, but is there any way i can find out for sure? i'm using crucial ballistixs (yeah i know, it's crucial ) and it won't boot at 5-5-5-18 so i loosened the timing to 6-6-6-20. which memory is 1200mhz stable for 24/7 these days? i'll post a template for all my settings later.

most of the time, the unstability shows when the whole computer freezes instead of certain cores failing when priming. is this memory problem is do i need to tune something else?
