Intel Plans to Limit LGA1155 Sandy Bridge Processor Overclocking

Information provided by Intel in its own presentations about its upcoming mainstream LGA1155 Sandy Bridge CPUs appears to confirm the company has designed the CPUs to deliberately limit overclocking. A video leaked to HKEPC and posted on YouTube (see from 2mins onwards) confirms the fact that only a 2-3 per cent OC via Base Clock adjustments will be possible. This is because Intel has tied the speed of every bus (USB, SATA, PCI, PCI-E, CPU cores, Uncore, memory etc) to a single internal clock generator issuing the basic 100MHz Base Clock. It looks like this might be the real reason the Intel ‘K-series’ of processors was introduced. If you want to overclock on the LGA1155 platform be sure to get a Sandy Bridge ‘K-Series’ processor. We contacted Intel about this story and their offical response is below.
