Memory Errors
• Make sure that the DIMM modules are properly and fully installed.
• Confirm that you are using the correct memory. Also, it is recommended that you use the
same memory type and speed for all DIMMs in the system. See Section 3.3 for memory
details.
• Check for bad DIMM modules or slots by swapping modules between slots and noting the
results.

poor quality power supply may cause the system to lose the CMOS setup configuration.
• Check that the motherboard battery still supplies approximately 3VDC. If it does not, replace
it. See
