Overclocking a Q9550 to 3.4 Ghz

Hi guys, I've been desperately trying to overclock this cpu to 3.4 ghz so I can get some extra juice out of it for when I order my new HD 7870 XT GPU. From what I've read it should easily OC to 3.4 Ghz on air, although I can't get it past 3.12 Ghz, without stability issues ( not even getting to logon screen without an error like "Corrupt boot manager" (something like that) or a bsod, I think it's something to do with my RAM settings because I change the FSB and voltages to reasonable values such as 1.3 v which is modest for this cpu i think, since cpu-z says it's at 1.28v at stock I also change the memory setting to 800Mhz and also the FSB to 1600 (Because my bios is weird and you have to put in the rated bus speed) and nothing, it crashes. What I'm asking guys is since I'm new to overclocking can you see anything I'm doing wrong? or maybe you know what I need to do to change my ram or cpu settings.

Solved! I figured out that I had to disable literally everything in the cpu settings

Then set voltages to:

vcore - 1.175
ht - 1.32

And my temps aren't exceeding 60 degrees
