NameSocket C32

Socket C32 was the socket for LGA-1207-packaged AMD Opteron 4000 Series microprocessors in servers optimized for energy efficiency and cost. Like the prior generation Socket F it supports two memory channels and three HyperTransport links, but was designed for DDR3 memory instead of DDR2. Socket C32 has a larger sibling Socket G34 for high performance systems with four memory channels and two additional 8-bit HT links. Uniprocessor Opterons with DDR3 memory controllers were released in packages for Socket AM3 and AM3+ which support two memory channels and a single HT link. Socket C32 was superseded by Socket SP3.

Each of the HyperTransport links can be used for I/O or, using an AMD proprietary protocol, cache coherent inter-socket traffic on multiprocessor systems. The 16-bit links can be unganged into two independent 8-bit links for instance to fully interconnect four sockets with links remaining for I/O. Most designs use only two links to achieve lower TDP.

Socket C32 has the same dimensions as Socket F, however the LGA-1207 packages for these sockets are mechanically, due to keying notches in different positions, and presumably electrically, incompatible with the other socket.

Socket C32 was used in AMD's 1- and 2-socket "San Marino" and "Adelaide" reference platforms. The processors for this socket are members of AMD's Family 10h with CPU cores based on the K10 microarchitecture, and Family 15h featuring the Bulldozer and Piledriver microarchitectures. They were fabricated on 45 nm and 32 nm processes.
