Doesn't work well with 10-11 multiplier, generally limited to around 310Mhz FSB regardless of environment.
Looks like 6-8 is alright.
High tRFC of 66 is good or just use Auto(in ASUS?) compared to 35-42 in 965P.
And 100+ isn't bad either if manual setting is stable.
1:1 and 5:6 are strong dividers, use those to get scale high
