Overclocking, techniques for increasing your computer's performance

 

 


 

Examples of overclocking


Taking the same example as before to show how overclocking should be done safely:

CPU Speed = Speed of the motherboard bus X CPU Multiplier

Initial speed 600 = 100 X 6

 

Motherboard bus speed

CPU Multiplier

CPU Speed

100 Mhz

x  6

= 600 Mhz.

 95  Mhz

   x  6.5

= 617 Mhz.

104 Mhz

x  6

= 625 Mhz.

106 Mhz

x  6

= 640 Mhz.

100 Mhz

   x  6.5

= 650 Mhz.

[...]

[...]

= [...] Mhz.

108 Mhz

   x  6.5

= 700 Mhz.

 

Starting with an initial speed of 600 Mhz, gradually increase the speed of the system by increasing or decreasing both the speed of the bus and the CPU multiplier to obtain gradual improvements in the speed of the processor. It is worth mentioning that even when you finally increase the speed of the processor by 100 Mhz, at no point do you exceed the 15% increase in the speed of the motherboard BUS, which means that even showing a slight improvement (in this case, 8 Mhz), in the speed of the memories, graphics cards, etc., none of these components has been overstretched.

The table below shows how some processors perform when their speed is increased:

 

350 MHz or higher Pentium II, first Pentium III

100 MHz BusFixed multiplier

Depends on the characteristics of the board (some offer buses of 105, 110, etc. and up to 133 MHz, others only 100 MHz)

Modern Pentium III ("Coppermine" main module)

100 or 133 MHz BusFixed multiplier

Depends on the characteristics of the board; in any case, they allow high overclocking thanks to their low voltage

Celeron without cache 66 MHz BusFree multiplier

66 MHz BusFree multiplier

Among the best for overclocking, but the lack of cache slows it down in many tasks, especially in data mining

Celeron "A" (with128 KB cache or "Mendocino")

66 MHz Bus Fixed multiplier

Among the best for overclocking, despite the fixed multiplier. Usually allows to go from 66 to 75 MHz. The 300 MHz model is famous for working (at times) at 450 MHz

AMD K7 Athlon

200 MHz (100x2) Bus Free multiplier

Fantastic overclocking capacity, although to take full advantage you need to open the casing and solder or use additional small circuit boards ("gold fingers")
