JP3:

NOTE: Based on the implementation of the Intel 440BX AGPset the EP-BXBS is

able to provide two front side bus (FSB) frequencies -- either 66MHz or 100MHz

for Slot 1 processors and memory operations. The mainboard will automatically

detect the correct FSB and set accordingly unless JP100 is set otherwise (see

jumper JP100 below). The primary and secondary processor slots both operate

synchronously at either 66MHz or 100MHz FSB, therefore if two processors are

used both will need to be of the same type and speed; otherwise the lower of the

two FSB frequencies will be set. When using the 100MHz FSB you must use

PC100 compliant SDRAM.

Memory is an important component of any 100MHz motherboard. When selecting

memory for use on your EPoX brand motherboard we recommend using only the

finest quality modules. EPoX would like to stress that using non-compliant PC100

SDRAM modules with a 100MHz FSB severely compromises the integrity of the

system.
