If there is no error beep, try to turn on the system without DIMM modules installed. If there

is still no error beep, replace the motherboard.

•

If there are error beeps, clear the CMOS settings by unplugging the power cord and con-

tacting both pads on the CMOS Clear Jumper (JBT1). Refer to chapter 2.

2. Remove all components from the motherboard, especially the DIMM modules. Make

sure that system power is on and that memory error beeps are activated.

3. Turn on the system with only one DIMM module installed. If the system boots, check for

bad DIMM modules or slots by following the Memory Errors Troubleshooting procedure

in this Chapter.

Memory Errors

1. Make sure that the DIMM modules are properly and fully installed.

2. Confirm that you are using the correct memory modules. Also, it is recommended that

you use the same memory type and speed for all DIMMs in the system. See Section 2.4

for memory details.

3. Check for bad DIMM modules or slots by swapping modules between slots and noting

the results.

4. Check the power supply voltage 115V/230V switch.

1. Make sure that you are using a high quality power supply. A poor quality power supply

may cause the system to lose the CMOS setup information.

2. The battery on your motherboard may be old. Check to verify that it still supplies

~3VDC. If it does not, replace it with a new one.

3. If the above steps do not fix the setup configuration problem, contact your vendor for

repairs.
