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.

CMOS Clear (JP5)
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.
