Here's another look at the DIL switch on the upgrade socket.
We restrict ourselves in the following description to motherboards with Socket 5, which are equipped with an Intel 430FX chipset. As the CPU clock (processor core clock) is derived from the processor bus clock and the clock multiplier, the highest possible clock rate should be chosen in principle for the upgrade. Otherwise such a high clock frequency is not achieved and performance is wasted. Here is an example to illustrate this: The Asus P55TP4XE that we tested offers a maximum processor bus clock of 66 MHz. As a rule, the board supports a maximum clock multiplier of 3.
|Socket 5 - Multiplier and Clock||CPU clock|
|3,0 x 66 MHz||200 MHz|
|2,5 x 66 MHz||166 MHz (Pentium 166)|
|2,0 x 66 MHz||133 MHz (Pentium 133)|
|1,5 x 66 MHz||100 MHz (Pentium 100)|
|1,5 x 60 MHz||90 MHz (Pentium 90)|
|1,5 x 50 MHz||75 MHz (Pentium 75)|
|Upgrade Adapter - Multiplier and Clock||CPU clock|
|6,0 x 66 MHz||400 MHz (AMD K6-2/400)|
|5,5 x 66 MHz||366 MHz (AMD K6-2/366)|
|5,0 x 66 MHz||333 MHz (AMD K6-2/333)|
|4,5 x 66 MHz||300 MHz (AMD K6-2/300)|
