Core i7, new CPU platform, featured as socket 1366, was launched by Intel last year. Nevertheless based on this structure, it has been positioned as high-end product until now and even in the future. During this period, market demand below high-end served by socket 775 old structure needs to be fulfilled as well. There’s a rumor saying socket 1156, applicable for CPU marked as Core i5 will replace those between high and middle end. However, recently the classification of product line has slightly changed. Socket 1366 remains the high-end platform. Besides Core i7, another platform featured as 6 cores, 12MB cache, will be launched. They call it- i9 Regarding socket 1156, no only Core i5 but also Core i7 supports 1156 pins meaning users have to distinguish by LGA 1366 or LGA 1156 instead of Core i5 or Core i7. Back to our spotlight, MSI P55-GD65, socket 1156 mainboard, is not ranked as MSI’s highest-end by telling from its Marketing name.

P55 platform principally has DDR3 dual channels. Although the performance is behind X58 trial channel structure, P55’s support range is enhanced to DDR3-1333. Hook’s slightly different from other socket platforms.
