Congratulations on purchasing the KOB KT266A FDSX mainboard. The KOB
KT266A FDSX mainboard is an ATX mainboard that uses a 4-layer printed
circuit board and measures 240 mm x 304 mm. The mainboard features a
Socket 462 that accommodates AMD Athlon processors supporting frontside
bus (FSB) speeds up to 133 MHz.
The KOB KT266A FDSX incorporates the VIA VT8366A Northbridge and
VT8233A Southbridge chipsets which combine support for the new high-
bandwidth Double Data Rate (DDR) 266 SDRAM, PC133 SDRAM and the AC
97 audio codec.
Note:
SDRAM provides 800 MBps or 1 GBps 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 GBps or 2.1 GBps by transferring data on both the ris-
ing 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.
