hello, i am new to ud3p and also overclocking

i am now having q9650, ud3p, g-skill ddr2 8000 4gb pack(1000mhz)

so i copied a setting from this post

478 x 9
cpu clock drive 800mv
pci-e 900mv
cpu clock skew 0ps
mch 50ps

ram divider 1:1

vcore 1.35
term 1.26
pll 1.45
ref .868

mch 1.32
ref .838

i can pass IBT 5times and i am lazy to other tests until i got a setting that satisfies me

so i would like to ask if there is anything i can do to get higher fsb or lower voltage?

i tried to boot with 4.35ghz, 4.4ghz or even 4.5ghz

but even i add a lot voltage to those fsb, its still unstable, most of the time it says"a clock interrupt was not received on a secondary processor within the allocated time interval"bsod

my cpu has a vid 1.225

thanks a lot!

and one more thing i dont wish to add too much voltage to it like 1.4X v for its temp and also lifetime :P
