LGA 1356
From Wikipedia, the free encyclopedia
LGA 1356, also called Socket B2, is an Intel microprocessor socket released in Q1 2012 with 1356 Land Grid Array pins. It launched alongside LGA 2011 to replace its predecessor, LGA 1366 (Socket B) and LGA 1567.[1] It's compatible with Intel Sandy Bridge-EN (also known as Romley-EN) and Ivy Bridge-EN microprocessors.

Description
LGA 1356 has 1356 protruding pins to make contact with the pads on the processor. Processors of LGA 1356 and LGA 1366 sockets are not compatible with each other since they have different socket notches.
While LGA 2011 was designed for high-end desktops and high-performance servers, LGA 1356 was designed for the dual-processor and low-end segment of the server market.
It supports 64-bit wide DDR3 triple channel memory, and equipped with 1 Intel QPI connection and 24 PCI Express lanes. Meanwhile LGA 2011 supports quad channel memory, 2 QPI connections and 40 PCIe lanes. Socket LGA 1155, desktop socket of the same generation supports dual channel memory. Each DDR3 channel can support one more DIMM (only applicable to DDR3 and not DDR3-L).[2]
Plans were leaked in early 2011, with estimated releases in the first quarter of 2012.[3] In September 2011, releases were estimated to be at the end of the first quarter of 2012.[4]
Physical design
Socket B2 processors have the following mechanical maximum load limits which should not be exceeded during heatsink assembly, shipping conditions, or standard use. Load above those limits will crack the processor die and make it unusable. The limits are included in the table below.
Processors using this socket have the same static load limit as previous models using LGA 1366 (Socket B).[5]
