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.Determine if different speeds of DIMMs have been installed and verify that 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 Registered ECC DDR2-400 (PC3200) SDRAM (*recommended by the manufacturer.)

4.Check for bad DIMM modules or slots by swapping a single module be- tween two slots and noting the results.

5.Make sure all memory modules are fully seated in their slots. As an interleaved memory scheme is used, you must install two modules at a time, beginning with Bank 1, then Bank 2, and so on (see Section 2-3).

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

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 informa- tion. 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, Super Micro 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.
