Recognize the P67 Platform

Despite design and architectural similarities between the Intel Series 60 chipsets for the brand new LGA1155 processors and the previous Series 50 chipsets for LGA1156 processors, none of them are compatible. In addition to the integrated GPU, the Sandy Bridge is equipped with more demanding OC restrictions. That is to say, it is less flexible than any LGA1156 processors.

OC : You need K SKU CPU

First, Intel has restricted base clock OC of Sandy Bridge processors, and the average BCLK OC range is about 10%. Given that the default BCLK of the Sandy Bridge is 100MHz, the OC range will fall within 110MHz. When compared with the processors of previous versions, the range is far less. In other words, we can only adjust the CPU ratio (multiplier) to run OC on the Sandy Bridge processors, and the K series processors without ratio block will surely be the primary choice for OC power users.

Apart from the range limit of processors, the design of the Series 60 chipsets also differs. Although the OC features of the P55 and H55 chipsets are similar (depending on the mainboard design), it is necessary for consumers to carefully select the Series 60 chip- sets in order to run OC on their systems. Despite the fact that the GPU is integrated with all Sandy Bridge processors, users are advised to choose the K-series processors and P67 mainbaords in order to exert the power of OC. However, when one wants to run OC on the GPU integrated with the processors, the H67 platforms will be the only choice. Simply speaking, it is impossible to run GPU OC on the P67 platforms or CPU OC on the H67 platforms.
