On multiprocessor models all three links support cache coherent connections to other DP or MP processors. On dual-processor models any one of these links may connect to another DP or MP processor. Uniprocessor Opterons with a DDR3 interface use Socket AM3 and AM3+.Īll three HyperTransport links on Socket F support connections to I/O devices. 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. 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 memory controllers of Family 10h can be configured for DDR2 and DDR3 DIMMs. Fr5 packages in Socket Fr6 support HT Gen 3 on all links. This socket is compatible with Fr5 and Fr6 packages. 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. Socket Fr6 (June 2009) accommodates Opteron " Istanbul" processors with six cores and 6 MiB 元 cache.Socket Fr5 is compatible with Fr1, Fr2, Fr5, and Fr6 package processors. It supports HyperTransport Gen 3 on inter-socket links. C and later processors fabricated on a 45 nm process. Socket Fr5 (November 2008) is an improved version for Family 10h rev.Socket Fr3 is incompatible with packages for other revisions. These processors support UDIMMs instead of RDIMMs. 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. Socket Fr2 is compatible with Fr1, Fr2, Fr5, and Fr6 package processors. 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. 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.This socket is compatible with Fr1, Fr2, and Fr5 package processors. 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. Socket F was superseded by Socket C32 and G34 which support DDR3 memory.ĪMD developed five revisions of Socket F: Uniprocessor Opterons with a DDR2 interface were released in packages for Socket AM2 and AM2+ with a single HT link. 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. 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.
