Configure Memory Your board comes with two DIMM sockets, providing support for up to 256MB of main memory using DIMM modules from 8MB to 128MB. For 66MHz front side bus CPUs use 12ns or faster memory; for 100MHz front side bus CPUs use 8ns (100MHz, PC100 compliant) memory. Memory Configuration Table Number of Memory Modules 1 DIMM 1 1st 1st SDRAM 8/16/32/64/128 Mbytes 2nd DIMM 2 Hardware Installation 2 RAM Type Memory Module Size (MB) Important: It is of prime importance that you install DIMM modules as outlined in the table above in order to preserve signal integrity on 100MHz front side bus systems. Step 4. Set SW1 for power up FSB clock and AGP bus clock. SW1 is used to adjust AGP bus clock frequency depending on the value of the front side bus (FSB) clock, also the setting of the SW1 determines the power up FSB clock which will remain effective until the BIOS set the FSB clock to the CMOS setting. SW1 Setting Power up FSB Clock 66MHz AGP Clock AGP Clock = FSB Clock ÷ 1 AGP Clock 100MHz = FSB Clock ÷ 1.5 Note1: The factory default setting for SW1 (Power up FSB clock and AGP bus clock) is 66MHz. CPUs that run on 100MHz may not boot at this frequency, so check SW1 before booting for the first time. Also, if the user changes the CPU, care should be taken to set SW1 in accordance with the FSB Frequency of the new CPU. Note2: The specification of maximum AGP bus Clock frequency is 66.6MHz. Set SW1 to open when you use a FSB 100MHz CPU. Set SW1 to close when you use a FSB 66MHz CPU. Set SW1 to open when you use a FSB 66MHz CPU but want to over clock the FSB clock to 100MHz via the BIOS setting. 8 SY-6ZB Quick Start Guide Step 5. Set the CPU Frequency You do not need to set any jumper for the CPU frequency. Instead, CPU setting are changed through the BIOS [CHIPSET FEATURES SETUP]. Please refer to Chapter 3 - Quick BIOS Setup for details on how to set the Slot 1 processor frequency. Step 6. Enable/Disable Power-On by Keyboard (JP50) You can choose to enable the Power-On by Keyboard function by shorting pin 2-3 on jumper JP50, otherwise, short pin 1-2 to disable this function. Power-On by Keyboard Enable Disable Short pin 2-3 to enable the Short pin 1-2 to disable the Power-On by Keyboard function. Power-On by Keyboard function. JP50 Setting 1 2 3 1 2 3 Important: When using the Power-On by Keyboard function, please make sure the ATX power supply can take at least 720mA load on the 5V Standby lead (5VSB) to meet the standard ATX specification. Step 7. Clear CMOS Data (JP5) Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JP5 for at least 5 seconds, and then by shorting pin 1-2 to retain new settings. This jumper can be easily identified by its white colored cap. CMOS Clearing JP5 Setting Clear CMOS Data Short pin 2-3 for at least 5 seconds to clear the CMOS. 1 2 3 Retain CMOS Data Short pin 1-2 to retain the new settings. 1 2 3 Note: You must unplug the ATX power cable from the ATX power connector when performing the CMOS Clear operation. 9 Hardware Installation SY-6ZB Quick Start Guide Note on Over-clocking Capability The SY-6ZB Motherboard provides over-clocking capability. Due to the over-clocking setting your system may fail to boot up or hang during run time. If this occurs, please perform the following steps to recover your system from the abnormal situation: 1. 2. 3. Turn off system power (If you use a ATX power supply, sometimes you have to press the power button for more then 4 seconds to shut down the system) Set the SW1 to short if you use a FSB 66MHz CPU Press and hold down the key while turning on the system power.
