BCLK overclocking not a problem for LGA2011 platform
 

Beside promising performance and a powerful integrated graphics circuits there is a dark cloud for the enthusiasts when Intel presents its first Sandy Bridge platform early next year. Intel's 6 series of chispet will ship with the clock generator for the processor bus integrated into the silicon. A clock generatorthat will also affect other units and buses around the system. As an effect of that you can't raise the BCLK frequency for moving up the clock frequency of the CPU, because this will also affect other components like USB and PCI Express and quickly cause instability.

Intel's solution is to unlock multipliers with some models - those marked with a K - that will be specifically for enthusiasts and wants to overclock, but even this does bring some light to LGA1155 for enthusiasts it nearly kills off the impact of the motherboard when overclocking, something we should not worry about when it comes to the enthusiast platform of Sandy Bridge.
