Socket 939

Socket 939 is a PGA socket designed for desktop K8 microprocessors. The socket is primarily used with Athlon 64, Athlon 64 X2 and Athlon FX microprocessors. AMD also manufactured uni-processor single and dual-core Opteron processors for the socket 939, although these processors were just re-branded Athlon 64/64 X2 CPUs with larger level 2 cache. In addition to that small number (compared to the total number of processors for this socket) of socket 939 Sempron processors was produced for this socket.

Upgrading socket 939 motherboards

While you can fit any processor in 939-pin ceramic or organic micro-PGA package into your motherboard, not all of them may be supported by the board. 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.
