Socket has

The Socket has (or Socket 462 ) is the socket used to fix the Processeur S AMD since the Athlon K7 to the bottom-of-the-range Athlon XP 3200+, and processors AMD, including the Duron and the Sempron. The socket is of type Zero Insertion Forces Pin Grid Array with 462 pins, of which 11 are stopped to ensure the codification during the assembly of the processor. Zero Insertion Forces means force of null insertion French . He thus lays out of a lever, or in the absence of a screw (on the laptops) to lock or unbolt the microprocessor, making his change easy without specific tools (for example to increase the performances of the computer).

Socket has replaces the Slot has first Athlon. Indeed, the cartouches with the Slot format has were justified by the use of memory hiding place separate heart of the processor. With the improvement of the manufactoring processes, AMD could introduce Athlon “Thunderbird”, which on the same chip joined together the heart of the processor (calculating units) and the memory hiding place level 2. Consequently, the use of a chart girl of the Slot type has is useless and increases the final cost price.

It should be noted that certain rare bottom-of-the-range computers have a welded processor with the mother chart, prohibiting her disassembling without specific tools.

From the fourth quarters 2004, the socket has was gradually replaced by the Socket 754, used by the processors Sempron and Athlon 64.

Technical specifications

Support of the frequencies of clock of processor between 600 MHz (Duron) and 2333 MHz (Athlon XP 3200+)
Socket has uses the protocol of bus DEC Alpha EV6, and is given rhythm at the frequency of 100,133,166 or 200 MHz. This bus is known as GDR ( Double Dated Spleen , rate of transfer doubles French ). Indeed, this bus uses the rising faces and the downward faces of the clock to transmit information, which makes it possible to double the rate of transfer compared to the real frequency (information by half-period instead of information per period in a traditional system).
It is the platform on which the first processor X86 1.0 GHz functioned.
