7 Chapter 1 Introducing the Mainboard Introduction Congratulations on purchasing the K7S6A mainboard. The K7S6A mainboard is an ATX mainboard that uses a 4-layer printed circuit board and measures 220 mm x 304 mm. The mainboard features a Socket 462 that accommodates AMD Athlon/Duron processors supporting frontside bus (FSB) speeds up to 100/133 MHz. The K7S6A incorporates the SiS745 Northbridge and Southbridge chipsets which combine support for the new highbandwidth Double Data Rate (DDR) 333 SDRAM, and the AC 97 audio codec. Note: SDRAM provides 800 MB/s or 1 GB/s data transfer depending on whether the bus is 100 MHz or 133 MHz. Double Data Rate SDRAM (DDR SDRAM) doubles the rate to 1.6 GB/s or 2.1 GB/s or 2.7 GB/s by transferring data on both the rising and falling edges of the clock. DDR SDRAM uses additional power and ground lines and requires 184-pin DIMM modules rather than the 168-pin DIMMs used by SDRAM.

22 Installing Hardware Installing the Processor Caution: When installing a CPU heatsink and cooling fan make sure that you DO NOT scratch the mainboard or any of the surface-mount resistors with the clip of the cooling fan. If the clip of the cooling fan scrapes across the mainboard, you may cause serious damage to both the mainboard and the processor. On most mainboards, there are small surface-mount resistors near the processor socket, which may be damaged if the cooling fan is carelessly installed. Avoid using cooling fans with sharp edges on the fan casing and the clips. Also, install the cooling fan in a well-lit work area so that you can clearly see the mainboard and processor socket. Before installing the Processor This mainboard automatically determines the CPU clock frequency and system bus frequency for processor. You may be able to change these automatic settings by changing the settings in the system Setup Utility. We strongly recommend that you do not overclock the mainboard to run processors or other components faster than their rated speed. Warning: Overclocking components can adversely affect the reliability of the system and introduce errors into your system. Overclocking can permanently damage the mainboard by generating excess heat in components that are run beyond the rated limits. This mainboard has a Socket 462 processor socket. When choosing a processor, consider the performance requirements of the system. Performance is based on the processor design, the clock speed and system bus frequency of the processor, and the quantity of internal cache memory and external cache memory. 16
