Socket 939
Encyclopedia
Socket 939 is a CPU socket
released by AMD in June 2004 to supersede the previous Socket 754
for Athlon 64
processors. Socket 939 was succeeded by Socket AM2
in May 2006. It is the second socket designed for AMD's AMD64 range of processors.
in May 2006. AMD has ceased the production of this socket to focus on current and future platforms. However, at least one new Socket 939 motherboard has been produced utilizing a modern AMD chipset since AMD transitioned to Socket AM2. In 2009 motherboard maker ASRock
released a new Socket 939 motherboard. The motherboard utilizes the AMD 785G IGP chipset and a SB710 southbridge.
Both single and dual-core processors were manufactured for this socket under the Athlon 64, Athlon 64 FX, Athlon 64 X2, Sempron and Opteron names. The Opteron 185 and Athlon 64 FX-60, both featuring a 2.6 GHz clock speed and 1 MB of Level 2 cache per core, were the fastest dual-core processors manufactured for this socket. The FX-57 ran slightly faster at 2.8 GHz, making it the fastest single core processor supporting the socket 939 interface.

(revision E or later) instruction sets. It has one HyperTransport
link of 16 bit width that can run as fast as 2000 MT/s.
In regards to video expansion slots, Socket 939 systems can be found with both AGP slots and PCI-E x16 slots as well.
Processors using this socket have 64KB each Level 1 instruction and data caches, and either 256KB, 512KB or 1 MB Level 2 cache.
