PC Over Clocking Part 2. Bios Set Up

ROM BIOS from, say, Award, has an embedded setup program, which allows you to change the basic configuration of the system. This information is permanently stored in CMOS RAM, so its contents will not be lost after turning the PC off. You can enter the Setup mode by pressing a certain key or combination of keys when you restart or reboot the computer. Usually the key is used for this purpose.
The system configuration is modified by setting the values of the appropriate parameters in BIOS Setup and then saving them in CMOS RAM. This procedure is known as BIOS Setup.
Most often, the overall performance of the entire computer system depends on the BIOS settings. In many cases, changing parameters in BIOS Setup provides a real possibility of significant improvement of the computer performance. This is particularly true for the parameters that deal with memory.
Generally, default settings ensure the stable operation of the entire system. However, these settings do not guarantee maximum performance. To achieve this, you'll need to try to select settings at which the computer will function at maximum performance and at the same time remain stable. In order to attain maximum performance by means of BIOS Setup, it is necessary to experiment with the settings that define time delays when accessing RAM (BIOS Memory Timing menu), internal, and/or external cache memory. It's also advisable to give some attention to the parameters that determine the modes of the video adapter and hard drive.
