overclocking my cpu

[rowannew]

hey guys the time has come for me new i3 to be oced as i have just gotten my arctic freezer 7 pro rev 2 installed and running. it is a core i3 540 at the clock of 3.06 ghz atm and it runs at 55degress with prime on. now i want this to get overclocked to 4ghz a few questions that i need to ask though as it is my first real overclock. having a look in the bios if i activate the xmp my cpu automatically clocks to 3.6ghz and i get about 1.3volts put through it. i was wondering if i could just change the bclk and fsb to something like 23x174 or maybe 20x200? any advice is great

bit of a bump here but would this work?
Vcore: 1.25v
Bclk: 182
FSB: x22
that would give me an overall overclock of 4004.7mhz.
should i do that after putting my xmp on so that the ram is already set to the required volts and stuff.

Probably best not to bother with XMP. Aggressive settings for the RAM can make it harder to clock the processor. Gradually increase the base clock, testing for stability at each stage (prime95 is good for this). When it becomes unstable increase the core and VTT voltages a little and try again. Rushing it is a good way to bork something. There is a good guide at the top of this forum.
