Memory Errors

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

2.You should be using registered ECC DDR-2 memory (see next page). Also, it is recommended that you use the same memory type and speed for all DIMMs in the system. See Section 2-4: "Installing Memory" on page 2-5for 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.

Losing the System’s Setup Configuration

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. Refer to Section 1-8for 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.
