You'll want to take into account the quality of your Motherboard as VRMs, MOSFETS are extremely important for voltages.
Marcus, i didnt know about VRM , that's good guide you posted there thanks
Well that's the problem my mobo doesn't like overclocking and its a bit old (ASUS P5E-vm do 2007).
It seems that i have to spend a lot of time changing settings in bios to be able to reach some satisfying overclock and notice any difference in performance.
Maybe if i updated my bios version ? maybe it would help i dont know ?
I try to avoid overclocking and just get better parts rather than overclock weaker/older models.
Well yes and no, the way the technology evolves you would have to buy new parts every 6 months or so and people i know including me dont want to spend money on something that is slightly better in performance just to get 7-10 fps more in games

Its been a while since i tried to overclock my crap mobo (asus p5e vm do) but i did a little bit more research and i found out that in order to pass 350 fsb some suggested that i should raise PCIe Frequency from 100 to 110-115 for some short period of time 10-15 to see how it goes and i just wanted to know if by any chance can cause or caused damage to my Video Card
At least i passed the limit of 3.2ghz that i was stuck for so long ;p
