Socket 1366 CPU
A,E
LGA 1366, also known as Socket B,[2][3] is an Intel CPU socket. This socket supersedes Intel’s LGA 775 (Socket T) in the high-end and performance desktop segments. It also replaces the server-oriented LGA 771 (Socket J) in the entry level and is superseded itself by LGA 2011. LGA stands for land grid array. This socket has 1,366 protruding pins which touch contact points on the underside of the processor (CPU)[4] and accesses up to three channels of DDR3 memory via the processor’s internal memory controller.
When operating in triple-channel mode, memory latency is reduced due to interleaving, meaning that each module is accessed sequentially for smaller bits of data rather than completely filling up one module before accessing the next one. Data is spread amongst the modules in an alternating pattern, potentially tripling available memory bandwidth for the same amount of data, as opposed to storing it all on one module.
The architecture can only be used when all three, or a multiple of three, memory modules are identical in capacity and speed, and are placed in three-channel slots. When two memory modules are installed, the architecture will operate in dual-channel architecture mode.[15]
