Figure. 320-pin Intel Socket 5 configuration.
The Pentium OverDrive for Pentium processors has an active heatsink (fan) assembly
that draws power directly from the chip socket. The chip requires a maximum 4.33
amps of 3.3V to run the chip (14.289 watts) and 0.2 amp of 5V power to run the fan (one
watt), which results in a total power consumption of 15.289 watts. This is less power
than the original 66MHz Pentium processor requires, yet it runs a chip that is as much
as four times faster!
Socket 6
The last 486 socket was designed for the 486 DX4 and the 486 Pentium OverDrive
processor. Socket 6 was intended as a slightly redesigned version of Socket 3 and had
an additional 2 pins plugged for proper chip keying. Socket 6 has 235 pins and accepts
only 3.3V 486 or OverDrive processors. Although Intel went to the trouble of designing
this socket, it never was built or implemented in any systems. Motherboard
manufacturers instead stuck with Socket 3.
Socket 7 (and Super7)
Socket 7 is essentially the same as Socket 5 with one additional key pin in the opposite
inside corner of the existing key pin. Socket 7, therefore, has 321 pins total in a 37x37
SPGA arrangement. The real difference with Socket 7 is not with the socket itself, but
with the companion voltage regulator module (VRM) circuitry on the motherboard that
must accompany it.
The VRM is either a small circuit board or a group of circuitry embedded in the
motherboard that supplies the proper voltage level and regulation of power to the
processor.
The main reason for the VRM is that Intel and AMD
wanted to drop the voltages the processors would use
from the 3.3V or 5V supplied to the motherboard by the
power supply. Rather than require custom power
