X8DAH+/X8DAH+-F/X8DAH+(-F)-LR User's Manual

No Video

1.If the power is on but you have no video, remove all the add-on cards and cables.

2.Use the speaker to determine if any beep codes exist. Refer to the Appendix for details on beep codes.

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 1-6 for details on recommended power supplies.

2.The battery on your motherboard may be old. Check to verify that it still sup- plies ~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.

Memory Errors

When a No Memory Beep Code is issued by the system, check the following:

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

2.Check if different speeds of DIMMs have been installed and check if the BIOS setup is configured for the fastest speed of RAM used. (It is recommended to use the same RAM speed for all DIMMs in the system.)

3.Make sure you are using the correct type of DDR3 Registered/Load Reduced ECC or Unbuffered ECC/Non-ECC SDRAM modules as recommended by the manufacturer. Refer to Page 1-6 for memory support.

4.Check for bad DIMM modules or slots by swapping a single module between all memory slots and check the results.

5.Make sure that all memory modules are fully seated in their slots. Make sure to follow the instructions given on DIMM population in Section 2-3 in Chapter 2.

6.Check the position of the 115V/230V switch on the power supply.
