(
default)
SDRAM frequency is the same as CPU
frequency (60/66/75/83/100 MHz)

SDRAM frequency is the same as AGP
frequency (66 MHz)
JP10

(default)
SDRAM is running at CPU frequency

1
SDRAM is running at AGP frequency
Note: 1. The host bus frequency can not be set to 75 MHz when using
a AGP card.
2. Use 8ns SDRAM or faster (for PC100) when using a host bus
frequency of 100MHz. However, this limitation does not
apply to EDO modules.
3. When the SDRAM module is slower than 8ns, JP9 and JP10
must be set to AGP frequency.
