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 Appendix A

for details on beep codes.

Note: If you are a system integrator, VAR or OEM, a POST diagnostics card is

recommended. For I/O port 80h codes, refer to App. B.

Memory Errors

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

2. You should be using proper ECC DDR-3 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 2-5 for 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 Conﬁ guration

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

supplies ~3VDC. If it does not, replace it with a new one.

3. If the above steps do not ﬁ x the setup conﬁ guration problem, contact your

vendor for repairs.

that as a motherboard manufacturer, we do not sell directly to end-users, so it is

best to ﬁ rst check with your distributor or reseller for troubleshooting services. They

should know of any possible problem(s) with the speciﬁ c system conﬁ guration that

was sold to you.
