To install a microprocessor


Socket Socket A for mikes AMD Athlon and Duron

On having bought a computer, one of the most habitual errors is to grant excessive importance to his brain, the microprocessor. To obtain a good yield not only a rapid mike is needed, but also a suitable quantity of memory RAM, a good graphic card, etc... or we can finish with the equivalent of an engine of Ferrari installed in the bodywork of a Seat 600, and in addition with a deposit of 5 liters of fuel.

Any way be already rapid or slow, the microprocessor is an essential element of the PC (on the other hand, there are human beings who manage well without scarcely using his brain...). If there has decided to be mounted its own PC which frenzied Frankenstein, or he tries to improve the one that it has right now, continue the following indications:

  1. Identify the type of microprocessor that he needs.
  2. Extinguish and disconnect completely the team...
  3. If there is already an installed mike, remove it.
  4. Connect the new mike, paying attention to his orientation.
  5. Put silicone termoconductora on the mike.
  6. Install and connect the set of spendthrift and fan.
  7. Form the motherboard for the new microprocessor.
  8. Check everything, connect the team, cross the fingers and...


1. - Identify the type of microprocessor that he needs. This is almost immediate in case of mounting a new PC, but not so much if it is a question of an update.

The principal information source in this respect is the motherboard. He will need to know:

Groove Slot 1
  • The type of (socket) socket or groove (slot) in that it owes "to prick itself" the mike. The most habitual are:
     - Socket 7: for mikes guy Pentium, Pentium MMX, AMD K6, K6-2 and K6-III, Cyrix...
     - Socket 370 PPGA: for mikes Celeron of up to 533 MHz and some Cyrix and ROUTE.
     - Socket 370 FC-PGA: for mikes Pentium III and Celeron of more than 533 MHz.
     - Socket A (462)): for the current AMD Athlon and Duron.
     - Socket 423: for the Pentium 4.
     - Slot A: for the first mikes AMD Athlon.
     - Slot 1: for mikes Pentium II, some Pentium III and some Celeron.

    For more information on this matter, consult the manual of his motherboard and this linkage.

  • The electrical characteristics and of configuration of the mike:
     - the external voltage (I/O) who needs (generally 3,3 V);
     - the internal voltage (core) who needs (it will be minor or just as that of I/O);
     - his multiplier (4x, 4,5x, 5x...) and his bus speed (66, 100, 133... MHz).

    For example, a 933 MHz Pentium III uses a bus ("Federal Security Service" or "external speed or of badge") of 133 MHz, a multiplier 7x (933=7x133) and generally voltages of 3,3 V (day pupil) and 1,7 V (intern).

In modern basic badges it is probable that everything is formed automatically, but the more know that the better it him will go. And eye to the updates: often the motherboard will not offer the speed of bus or the voltage that the new mike needs, other times it will have to update earlier the BIOS...


2. - If it has not already done it, extinguish and disconnect completely the team, unburden of static electricity... anyway, continue these advices. Detail of one of the side eyes and of the groove for alignment in a mike Athlon in format Slot A


3. - If there is already an installed mike, remove it.

In case of mikes connected to grooves (Slot A or Slot 1) it will have to liberate the eyes of the wings, which design changes a little from a few basic badges to others and according to the type of cartridge used (none in case of the Celeron for Slot 1 or the adapters of Socket 370 to Slot 1, go nudes); in any case, it is easy. With free them, pull the mike up, and it is already.
A delicate moment: pressing the hoop of subjection of the fan

If it is a question of a modern mike for socket, the operation is also quite simple thanks to the mechanical system ZIF, who allows to install the mikes without realizing force by no means. The bothersome only thing can be to release the metallic hoop that holds the fan; put attention on having done it, do not be that it comes undone suddenly and infuriates the motherboard, breaking some of the lines of circuit... Socket Socket A with the lever in the position to insert or to remove mike

As soon as the fan was removed, to release the mike simply put the lever in vertical position, with what the ancient mike will have to remain completely free.
