SOYO SY-7VBA133U Memory Configuration Table

Step 3. Configure Memory

Your board recommend a limit of 3 DIMMs or 6 banks at 133 MHz for 1.5GB max memory

using unbuffered DIMM modules from 8MB to 512MB. Supports optional ECC (single-bit

error correction and multi-bit detection) or EC (error checking) capability separately

selectable on a bank-by-bank basis. On this motherboard, DRAM speed can be set

independent from the CPU front side bus speed. Depending on the DRAM clock speed

setting in the BIOS setup, appropriate memory modules must be used. For FSB 66MHz

speed, use PC66 or PC100 memory; for FSB 100MHz speed, use PC66/PC100/PC133

memory; for FSB 133MHz speed, use PC100 or PC133 memory.

In some cases the CMOS memory may contain wrong data, follow the steps below to clear

the CMOS memory.

1. Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JP5. This jumper

can be easily identified by its white colored cap.

2. Then put the jumper back to 1-2 to allow writing new of data into the CMOS memory.

Note: You must unplug the ATX power cable from the ATX power connector when

performing the CMOS Clear operation.
