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 compatible with future Ivy Bridge-E processors.
