Socket F was AMD's second socket for server platforms, a socket for LGA-1207-packaged AMD Opteron and Athlon 64 FX microprocessors with integrated DDR2 memory controllers. It succeeded Socket 940 which has a DDR interface and like Socket F supports three HyperTransport links to connect the processors in 2-, 4-, and 8-socket systems. Uniprocessor Opterons with a DDR2 interface were released in packages for Socket AM2 and AM2+ with a single HT link. Socket F was superseded by Socket C32 and G34 which support DDR3 memory.

AMD developed five revisions of Socket F:

• The initial Socket F a.k.a. Fr1 was designed for Opteron "Santa Rosa" processors which are members of AMD's NPT Family 0Fh with dual CPU cores based on the K8 microarchitecture and fabricated on a 90 nm process. Its desktop counterpart is Socket AM2. This socket is compatible with Fr1, Fr2, and Fr5 package processors.

• Socket Fr2 (August 2007) is an improved version for Family 10h processors with four CPU cores based on the K10 microarchitecture and fabricated on a 65 nm process. It raised the maximum memory data rate to 800 MT/s and uses dual power planes supplying the cores and northbridge, a power saving feature. Its desktop counterpart is Socket AM2+. Socket Fr2 is compatible with Fr1, Fr2, Fr5, and Fr6 package processors.

• Socket Fr3 a.k.a. 1207 FX or Socket L1 (November 2006) was derived from Fr1 for dual-core Athlon 64 FX processors on the dual-socket Quad FX a.k.a. "4x4" desktop platform. These processors support UDIMMs instead of RDIMMs. Socket Fr3 is incompatible with packages for other revisions.

• Socket Fr5 (November 2008) is an improved version for Family 10h rev. C and later processors fabricated on a 45 nm process. It supports HyperTransport Gen 3 on inter-socket links. Socket Fr5 is compatible with Fr1, Fr2, Fr5, and Fr6 package processors.

• Socket Fr6 (June 2009) accommodates Opteron "Istanbul" processors with six cores and 6 MiB L3 cache. It supports HyperTransport Gen 3 on I/O and inter-socket links, AMD's HT Assist (probe filter) technology, APML, and raises the maximum HT data rate to 4800 MT/s. This socket is compatible with Fr5 and Fr6 packages. Fr5 packages in Socket Fr6 support HT Gen 3 on all links.

The memory controllers of Family 10h can be configured for DDR2 and DDR3 DIMMs. Opteron DP and MP models with a DDR3 interface were released in a LGA-1207 package for Socket C32 and a LGA-1944 package for Socket G34. The packages for Socket F and C32 have the same dimensions but are mechanically, due to keying notches in different positions, and presumably electrically, incompatible with the opposite socket. Uniprocessor Opterons with a DDR3 interface use Socket AM3 and AM3+.

All three HyperTransport links on Socket F support connections to I/O devices. On dual-processor models any one of these links may connect to another DP or MP processor. On multiprocessor models all three links support cache coherent connections to other DP or MP processors.

Processors using Socket F

The Opteron 2000 series supports dual socket systems, the 8000 series are multiprocessors for systems with up to eight sockets. (Series 1000 and 3000 are uniprocessors using Socket AM2/AM2+/AM3/AM3+ instead. Series 4000 and 6000 use Socket C32 and G34, respectively, in systems with up to four sockets.)
