Socket 7 (Socket7)
Socket 7 was introduced by Intel for it's Pentium 133 - 200 MHz processors and for Pentium MMX processor family. The major feature of the new socket was support for dual plane voltage - the socket could supply different voltages to processor core and I/O logic. At the same time, the socket 7 was backward compatible with socket 5, and it was possible to run older (single voltage) processors in socket 7 motherboards. For their next generation of processors Intel chose different socket type - slot 1, and completely abandoned socket 7. Luckily, Intel competitors continued to support socket 7 architecture, and they even enhanced it by creating a "Super socket 7" specification by adding support for 100 MHz bus frequency, backside L2 cache and frontside L3 cache.
Socket 7 has 321 pin holes arranged as 37 x 37 pin matrix. The socket has the same size as the Socket 5, but the socket 5 has only 320 pin holes. The extra pin on socket 7 processors is not electrically connected and it's main purpose is to prevent socket 7 processors to be inserted into socket 5 motherboards.

Upgrading socket 7 motherboards
Although many socket7 microprocessors will fit into your motherboard, not all of them may be supported by the board. To determine the fastest processor for your motherboard you'll need to:
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 and Shuttle motherboards please check CPU-Upgrade motherboard database.
