Are you a fan of Intel CPUs but also love overclocking? Then there may be a reason to not look forward to the upcoming Sandy Bridge. 

According to slides shown by Hong Kong-based HKEPC's YouTube channel, Sandy Bridge will have a single single internal clock generator issuing the basic 100MHz base clock that'll run for the USB, SATA, PCI, PCI-E, CPU cores, Uncore, and RAM.

The clock generator will be a part of the P67 chipset and will transmit via to DMI bus to the CPU. This means that the user won't be able to tweak the CPU speed without affecting the entire system.

Bit-tech claims to have spoken to one of its Taiwanese motherboard sources, and early tests show that even upping the base clock by a measly 5 MHz caused the USB to fail and SATA bus to corrupt.

We're sure that motherboard makers are doing everything they can to come up with a way around this, which could make for a huge competitive point that'll cater to the enthusiast market.
