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.

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. Make sure that DIMMs of different speeds or types are not installed and verify that

the BIOS setup is conﬁ gured for the fastest speed of RAM used. It is recom-

mended that you use the same speed of RAM for all DIMMs in the system.

3. Make sure you are using the correct type of DDR2 Fully Buffered (FBD) ECC

667/533 SDRAM (*recommended by the manufacturer.)

4. Check for bad DIMM modules or slots by swapping a single module between

four 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 pairs of memory modules of the

same type and the same speed 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.
