socket 3 การใช้

• Socket 3 resulted from Intel's creation of lower voltage microprocessors.
• "' Socket 3 "'was a series of CPU Sockets for various x86 microprocessors.
• So few motherboards, if any, were produced that used it, especially as the Socket 3 standard was already sufficient.
• While originally offered with a 33 MHz 80486DX, the 750CD could be upgraded to later Socket 3 processors such as the 80486DX2 through the use of third party CPU upgrade adapters or interposers.
• IBM later marketed Socket 3 168-pin PGA Blue Lightning 486 CPUs, but these are technically not related to earlier Blue Lightning models as they are based on the Cyrix Cx486 CPU core.
• Since having a clock multiplier of four was not part of the original Socket 3 design, AMD made the 5x86 accept a 2x setting from the motherboard and instead operate at a rate of 4x.
• The similarly named SGS-Thomson ST5x86 and AMD Am5x86 which was essentially a fast 486 ( not an all-new design like the Cyrix part ) but which had broadly similar performance, used the same Socket 3, and was introduced at the end of the same year.
• Socket 3 was a 237-pin low insertion force ( LIF ) or zero insertion force ( ZIF ) 19?9 pin grid array ( PGA ) socket suitable for the 3.3 V and 5 V, 25 50 MHz Intel 486 SX, 486 DX, 486 DX2, 486 DX4, 486 OverDrive and Pentium OverDrive processors as well as AMD Am486, Am5x86 and Cyrix Cx5x86 processors.
