Socket G2, also known as rPGA 988B is Intel's CPU socket used with their line of mobile Core i7, the successor to the Core 2 line, and also with several mobile Core i5 and Core i3 processors. It is based on Intel's Sandy Bridge architecture. Like its predecessor, socket G1 systems, it can only run in dual-channel memory mode, but with data rates up to 1600 MHz (as opposed to the triple-channel mode which is unique to the LGA-1366 platform and subsequent Xeon sockets). They 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. Supermicro, for example, produced a number of 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]
There are rPGA 989 sockets (as shown on the left) that can take Socket Socket G1 (rPGA988A) or Socket socket G2 (rPGA988B).
