My problem is that the sistem becomes unstable if I overclock to 2.7Ghz, resets or jams in windows. I increased the Vcore values but I have the same problem. DDR divider is 1:1 (600Mhz for 300 FSB).
I bios I disabled C1, TM2, intel spped step functions. I used Auto for PCI Express (if I set manualy to 100 the system won't boot at all).
Does anybody have an IDEEA what to do? I read on forums that 2.9 or 3.0 Ghz are easally obtained.
You will get more response if you post a thread about this in general hardware.
You are using a 945 chipset, which isnt great for overclocking, and 667Mhz RAM, which isnt ideal either.
Really, you can either just make the best of what your current hardware can do, or buy hardware that overclocks well.
Sorry I cant be of more help
