SUPER P4SGA/P4SGL/P4SGR/P4SGE User's Manual

NOTE

If you are a system integrator, VAR or OEM, a POST diagnos-

tics card is recommended. For I/O port 80h codes, refer to

App. B.

Memory Errors

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

2. You should be using unbuffered DDR memory (see next page). Also, it

is recommended that you use the same memory 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 and noting the results.

4. Check the power supply voltage 115V/230V switch.

Losing the System’s Setup Configuration

1. Ensure 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 fix the Setup Configuration problem, contact

your vendor for repairs.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also,

note that as a motherboard manufacturer, Supermicro does not sell directly

to end-users, so it is best to first check with your distributor or reseller for

troubleshooting services. They should know of any possible problem(s)

with the specific system configuration that was sold to you.

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently

Asked Questions' (FAQs) sections in this chapter or see the FAQs on our

web site (http://www.supermicro.com/techsupport.htm) before contacting

Technical Support.

2. BIOS upgrades can be downloaded from our web site at
