Memory Errors; Losing The System's Setup Configuration; When The System Becomes Unstable - Supermicro A2SAP-H User Manual

Memory Errors

1. Make sure that the DIMM modules are properly and fully installed.
2. Confirm that you are using the correct memory. Also, it is recommended that you use
the same memory type and speed for all DIMMs in the system. See Section 2.4 for
memory details.
3. Check for bad DIMM modules or slots by swapping modules between slots and noting
the results.

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 1.5 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.

When the System Becomes Unstable

A. If the system becomes unstable during or after OS installation, check the following:
1. Memory support: Make sure that the memory modules are supported by testing the
modules using memtest86 or a similar utility.
Note: Click on the Tested Memory List link on the motherboard product page to see
a list of supported memory.
2. HDD support: Make sure that all hard disk drives (HDDs) work properly. Replace the
bad HDDs with good ones.
3. Heatsink: Check that the heatsink is installed properly.
4. Adequate power supply: Make sure that the power supply provides adequate power to
the system. Make sure that all power connectors are connected. Please refer to our
website for more information on the minimum power requirements.
5. Proper software support: Make sure that the correct drivers are used.
