SOYO SY-5EMA+ quick start PCI Clock JP10, Configure Memory

SY-5EMA+Quick Start Guide

JP8 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	PCI Clock	JP10	JP8	JP9	SDRAM
Clock	Clock					Clock
66MHz	66MHz	33MHz	1-2	2-3	2-3	66MHz
75MHz	75MHz	37.5MHz	1-2	2-3	2-3	75MHz
83MHz	55MHz	27.5MHz	2-3	1-2	1-2	55MHz
			1-2	1-2	2-3	83MHz
95MHz	63.4MHz	31.7MHz	2-3	1-2	1-2	63.4MHz
			1-2	1-2	2-3	95MHz	Installation
100MHz	66MHz	33MHz	2-3	1-2	1-2	66MHz
			1-2	1-2	2-3	100MHz
112MHz	75MHz	37.5MHz	2-3	1-2	1-2	75MHz
			1-2	1-2	2-3	112MHz
124MHz	82.6MHz	41.3MHz	2-3	1-2	1-2	82.6MHz
			1-2	1-2	2-3	124MHz

Note: Use 8ns or faster SDRAM modules (for PC100) when SDRAM is set to run at

the frequency of 95/100MHz.

Step 4. Configure Memory

Your board comes with three DIMM sockets, providing support for up to 768MB of main memory using DIMM modules from 8MB to 256MB. For 66MHz host bus CPUs use 12ns or faster DIMM modules; for 83MHz host bus CPUs use 8ns modules.

Memory Configuration Table

MEMORY		DIMM Banks
CONFIGURATION	DIMM 1	DIMM 2	DIMM 3
RAM Type	FPM/EDO/SDRAM	FPM/EDO/SDRAM	FPM/EDO/SDRAM
Single RAM	8/16/32/64/128/256	8/16/32/64/128/256	8/16/32/64/128/256
Module Size (MB)
Note: Do not use FPM or EDO type of SIMM/DIMM if you already use SDRAM.
