Socket AM2

Socket AM2 is a socket for high-performance and budget desktop microprocessors. The socket was officially introduced on May 23, 2006. On that day AMD released new Athlon 64 X2 5000+ and Athlon 64 FX FX-62 microprocessors, and announced complete lineup of Athlon 64, Athlon 64 X2 and Sempron processors for socket AM2. These were not the first socket AM2 processors, though. The first socket AM2 microprocessors were Energy efficient Athlon 64, Athlon 64 X2 and Semprons - they were introduced a week earlier, on May 16, 2006.

The socket AM2 works with single, dual, triple and quad-core desktop processors with frequencies up to 3.2 GHz. The socket supports dual-channel DDR2 SDRAM memory controller and one 1000 MHz HyperTransport link. The Socket AM2 is not the latest socket for desktop AMD microprocessors. The latest socket for desktop AMD CPUs, Socket AM2+, supports faster HyperTransport link, up to 2.6 GHz, and offers separate power planes for the CPU core and integrated memory controller. The socket AM2+ is compatible with socket AM2, that is socket AM2+ processors can be used in socket AM2, and vice versa.

Picture of Socket AM2

The socket AM2 has 940 pin holes. The pin holes are arranged as 31 x 31 grid, with 21 pin holes plugged.

Supported processors

All processors in the table below will physically fit into the socket, but not all of them are supported by all motherboards. If you're upgrading an old computer system please make sure that the CPU is compatible with your motherboard. Please see "Upgrading socket AM2 motherboards" section below for information on how to determine what microprocessors can be supported by your motherboard.

Upgrading socket AM2 motherboards

If you want to upgrade to the fastest socket AM2 microprocessor then your upgrade choices are:

  • If you're planning to do a lot of audio or video encoding, 3D rendering, running other multi-threaded applications, or running many processes at once, then your best upgrade option is Phenom X4 9950 or Phenom X4 9850.
  • If you need maximum performance in existing games (Crysis, Oblivion, etc) then the best upgrade option is Athlon 64 X2 6400+. Second Generation Opteron 1224 SE is as fast as the Athlon X2 6400+, but it's not recommended for upgrades due to much higher price.

For cheap computer systems, used primarily for e-mail, browsing and office-type applications, either Athlon 64 LE-16xx or slowest Athlon 64 X2 processors would be more than sufficient.

To determine what processors are supported you'll need to:

  • Determine manufacturer and model of your motherboard,
  • Search on manufacturer's website for the motherboard model.

To determine upgrade options for brand name computers (like Dell or HP) try to search for computer model on computer manufacturer website.

For upgrade information for ABIT, ASRock, ASUS, DFI, ECS, Gigabyte Technology, Jetway, MSI, PC Chips motherboards please check CPU-Upgrade motherboard database.

Typo in first sentence. 2008 should be 2006?

Response: I fixed the typo. Thank you!

the upcoming Phenom Deneb 45nm Socket AM3 processors will be compatible with AM2/AM2+ Sockets, however AM2/AM2+ processors wont work in AM3 Sockets
