SOYO SY-5EH5 manual Set JP7,JP9,JP10 for Sdram frequency, Cpu Bus Agp Bus, JP7 JP9, Sdram Clock

Hardware Setup SY-5EHM/5EH5 V1.2

Step 5. Set JP7,JP9,JP10 for SDRAM frequency

JP7 is used to indicate the frequency of the CPU bus clock to the ETEQ chipset.

JP9 and JP10 are used to determine that the SDRAM is running at the frequency of the CPU bus clock or the AGP clock.

CPU BUS	AGP BUS	JP10	JP7	JP9	SDRAM Clock
Clock	Clock
66MHz	66MHz	1-2	2-3	2-3	66MHz
75MHz	75MHz	1-2	2-3	2-3	75MHz
83MHz	55MHz	2-3	1-2	1-2	55MHz
		1-2	1-2	2-3	83MHz
95MHz	63.4MHz	2-3	1-2	1-2	63.4MHz
		1-2	1-2	2-3	95MHz
100MHz	66MHz	2-3	1-2	1-2	66MHz
		1-2	1-2	2-3	100MHz

Note: Use 8ns or faster SDRAM modules (PC100 compliant) when

SDRAM is set to run at the frequency of 95/100 MHz.
