X7SBi User's Manual
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 installed and fully seated in
the slots.
2. You should be using unbuffered, ECC/Non-ECC DDR2-800/667 memory (see
the next page). Also, it is recommended that you use the memory modules
of the same type and 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 to
see if you can locate the faulty modules.
4. Check the power supply voltage 115V/230V switch.
Losing the System's Setup Confi guration
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 sup-
plies ~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.
