Cant get this OC stable, Please help!

[PhikMan]

Hey, i recently started Ocing my rig for the first time and i sorta need some help, i just cant get it stable at 3.6 gig.

My rig:
Asus maximus formula
q9450
4 gig dominator ram
TRUE with Coolermaster silent fan
9800 gtx

Bios settings
CPU: 8 * 450
Vcore: 1.34375 V

Ram: 1081 Mhz
5,5,5,15 2T
Voltage: 2.30

i had it sorta stable at 3.6 with vcore of 1.3 and DRAM as 2.26(i think). it was running prime for a couple of hours till it errored.

any help/suggestions is appreciated to help me get this stable. thanks

EDIT::

drop vcore to 1.3, dram voltage to 2.1, ram frequency to 900 mhz
testing now

i think the Q9450 has a FSB hole around 450..so yea, that and it's low multy...you most likely won't get any higher than you already are lol

i think i got it stable at the above mention specs in the edit, but after running prime for a a hour and a half, an error pops up saying "memory could not be read" and then it quits prime. im thinking that my rams bad, cause its done this before even before OCing...

I couldn't get mine stable at 3.4GHz. Prime returns an error almost immediately on either Core 3 or Core 4...I've gone up as high as 1.3V. Maybe it needs to go a little higher? Right now I'm at 1.26V at 3.2GHz.
