Intel plans to deliberately limit Sandy Bridge overclocking

Yeh i read that increasing it by 5mhz only causes the PCIE and system to freeze, sounds crap eh

Well it hasn't to be the PCI-E bus but more like the DMI bus, since on currenct platforms its locked at a fixed frequency and uneffected by increasing the reference frequency. But now for the value/mainstream platform its directly tied to the reference clock.

And if the signals form the DMI bus get "unclear" you lose the comunication to the PCH.

You don't have this problem with the enthusiast plattform since there you can chage the multis and keep them in certain frequency spectrum.

Anyway as some posters already said, it to eraly to say anthing absolute. We'll know more next IDF in september.
