Congratulations on purchasing the KOB KT266A FSX mainboard. The KOB
KT266A FSX mainboard is an ATX mainboard that uses a 4-layer printed cir-
cuit board and measures 222 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 FSX incorporates the VIA KT266A Northbridge and VT8233
Southbridge chipsets which combine support for the new high-bandwidth
Double Data Rate (DDR) 266 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 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.
