LGA 2011
Encyclopedia
LGA 2011, also called Socket R, is a CPU socket
by Intel
. It replaces Intel's LGA 1366 (Socket B) and LGA 1567
in the performance and high-end desktop and server platforms. The socket has 2,011 protruding pins which touch contact points on the underside of the processor.
Socket R uses QPI to connect the CPU to additional CPUs and to the SouthBridge
in a dual socket system. DMI 2.0
connects Sandy Bridge
E-series processors to the Intel X79
chipset. The CPU handles northbridge
functions, such as memory control, PCIe control, DMI, FDI, and other functions integrated on chip.
The socket was released on 14 November 2011, and supports Sandy Bridge
E-series processors with 4 memory channels of DDR3-1600, as well as, 40× PCIe 2.0 or 3.0 lanes; The Extreme Edition processor supports six cores with 15 MB of shared L3 cache on a ring bus and a quad-channel DDR3 memory controller. LGA 2011 motherboards have either 4 or 8 DIMM
slots which allows for a maximum support of 32GB, 64GB or 128GB of memory
. Socket R also has to ensure platform scalability beyond eight cores and 20 MB of cache.
LGA 2011 will also be backwards compatible with upcoming Ivy Bridge-E processors.
