Socket G2

Although nearly all motherboards using this socket are intended for mobile products like laptops, a few desktop boards using this do exist. Supermicro, for example, produced a number of mini ITX motherboards using the QM77 chipset.

Technical specifications

• Pins arranged in a 35 × 36 grid array (it is incompatible with G1 socket due to different placing of one pin)
• 18 × 15 size grid removed from the center
• Utilization of cam-actuated retention mechanism
• The r in rPGA refers to reduced pitch which is 1 mm × 1 mm in this socket design.

rPGA 989 (as shown on the right) is a socket that can take Socket G1 (rPGA988A) or Socket G2 (rPGA988B) processors.

Supported memory:

• DDR3 SoDIMM (1066-1333 MHz, Sandy Bridge); DDR3\DDR3L 1600 may work without DDR3L power optimisations and with 1333 MHz clock speed.
• DDR3 SoDIMM (1066-1600 MHz, Sandy Bridge Core i7-2720QM and faster).
• DDR3\DDR3L SoDIMM (1066-1600 MHz, Ivy Bridge).
