2. Use the speaker to determine if any beep codes exist. (Refer to Appendix A
for details on beep codes.)
3. Remove all memory modules and turn on the system. (If the alarm is on, check
the specs of memory modules, reset the memory or try a different one.)
Memory Errors
1. Make sure that the DIMM modules are properly installed and fully seated in the
slots. You should be using unbuffered Non-ECC DDR2 667/533/400 memory
(See the next page). Also, it is recommended that you use the memory mod-
ules of the same type and speed for all DIMMs in the system.
2. Check for bad DIMM modules or slots by swapping modules between slots to
see if you can locate the faulty modules.
3. Check the power supply's 115V/230V selector switch.

1. Please be sure to use a high quality power supply. A poor quality power supply
may cause the system to lose the CMOS setup information. Refer to Section
1-5 for details on recommended power supplies.
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 x the Setup Conguration problem, contact your
vendor for repairs.

reseller for troubleshooting services. They should know of any possible problem(s)
with the specic system conguration that was sold to you.
