This article is part of the CPU socket series

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.[1] The socket has 2011 protruding pins which touch contact points on the underside of the processor.

Socket R uses QPI to connect the CPU to additional CPUs. DMI 2.0 is used to connect the processor to the PCH. The memory controller and 40 PCIe lanes are integrated on the CPU. On a secondary processor an extra ×4 PCIe interface replaces the DMI interface. As with its predecessor LGA 1366 there is no provision for integrated graphics.

The socket was released on 14 November 2011,[2] and supports 4 DDR3 SDRAM memory channels with 1 unbuffered DIMM per channel, as well as 40× PCIe 2.0 or 3.0 lanes.[3] LGA 2011 also has to ensure platform scalability beyond eight cores and 20 MB of cache.[4]

LGA 2011 is used by Sandy Bridge-E/EP and Ivy Bridge-E/EP processors with the corresponding X79 (E - Enthusiast) and C600-series (EP - Xeon) chipsets.

Chipsets[edit]

Information for the Intel X79 (for Desktop) and C600 series (for Workstation/Server and codenamed Romley[5]) chipset can be found in the table below. The Romley (EP) platform was delayed approximately one quarter, allegedly due to a SAS controller bug.[5]

The X79 appears to contain the same silicon as the C600 series, with ECS having enabled the SAS controller for one of their boards, even though SAS is not officially supported by Intel for X79.[6]

1 The X79 chipset allows for increasing the base clock(bclk), Intel calls it CPU Strap, by 1.00x, 1.25x, 1.66x or 2.50x. The CPU frequency is derived by the bclk times the CPU multiplier.
