Socket FM1 is a socket for mid-class and budget AMD desktop microprocessors, built on 32nm technology. The socket was introduced in July 2011, and initially supported A6- and A8-series quad-core CPUs. Over the course of the next few months, AMD also released A4- and Athlon II X4 socket FM1 microprocessors. Several additional families for the socket, such as E2-Series, Athlon II X2 and Sempron X2, are expected to launch in the fourth quarter 2011 and in 2012. Currently (September 2011), the socket FM1 works with dual, triple and quad-core desktop processors with frequencies up to 3000 MHz. The socket supports dual-channel DDR3 memory up to DDR3-1866, and, optionally, integrated graphics processing unit.
The socket FM1 has 905 pin holes. The pin holes are arranged as 31 x 31 grid, with 13 pin holes plugged at the corners of the grid, 7 x 5 section removed from the center of grid, and additional 8 pin holes plugged close to the center.
All microprocessors, listed in the table below, physically fit into the socket, but not all of them may be supported. If you're upgrading a computer system, please make sure that the new CPU is compatible with your motherboard. To determine what microprocessors are supported by your motherboard please see "Upgrading socket FM1 motherboards" section below.
There are no processors from other manufacturers, compatible with this socket.
