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 South-
bridge chipsets which combine support for the new high-
bandwidth 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
mo dules rather than the 168-pin DIMMs used by
SDRAM.
