Question re: OC of i5/i7 systems

[Zathras]

My knowledge of overclocking is rusty and I don't really grok the architecture of the i5/i7 systems. I know you can overclock by increasing the FSB from the default value of 133. On *old* PCs, increasing the FSB past 133 would affect the PCI/IDE speeds because they were on a fixed divider relative to FSB. So if you pushed the FSB too much you were at risk of problems with the hard drive and PCI peripherals.

Is this still the case with the i7/i5? Or is the FSB disconnected or independent from stuff like the PCI/IDE frequency?

With the i5 you change the base clock and/or multiplier. That way you leave the FSB alone. The default BCLK is 133MHz. You can overclock decently with Turbo on. Or higher by changing voltages, etc. Here are a few more articles:

The i5 is a mad overclocker if you want. It's also a smart overclocker if you prefer. Just a different method than in the past. A Guy
