Socket G2, also known as rPGA 988B is
triple-channel mode which is unique to the LGA-1366 platform and subsequent Xeon sockets). Socket G2 CPUs are also known as FCPGA988 socket processors, which should be pin compatible with PPGA988.[2]
Although nearly all motherboards using this socket are intended for mobile products like laptops, a few desktop boards using this do exist.
mini ITX motherboards using the QM77 chipset.[3]
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.[4]
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[5]).
- DDR3\DDR3L SoDIMM(1066-1600 MHz, Ivy Bridge).
