Memory Errors
1. Make sure the DIMM modules are properly and fully installed.
2. You should be using unbuffered ECC DDR II-533/400 memory (see the
next page). Also, it is recommended that you use the same memory
speed for all DIMMs in the system. See Section 2-4 for memory
limitations.
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.
Losing the System’s Setup Configuration
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 1-6 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 fix the Setup Configuration problem, contact
your vendor for repairs.
