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.

Memory Errors
1. Make sure the DIMM modules are properly and fully installed.
2. Determine if different speeds of DIMMs have been installed. It is recom-
mended to use the same RAM speed for all DIMMs in the system.
3. Make sure you are using the correct type of ECC DDR-200 SDRAM (-
utilizing DDR-266 operating at 200 MHz). EDO SDRAM and PC100/133
SDRAM are not supported.
4. Make sure all memory modules are fully seated in their slots. As an
interleaved memory scheme is used, you must install four or eight iden-
tical memory modules at the same time, beginning with DIMM1-
DIMM4(sockets colored in blue). (If eight DIMMs are used, install DIMM5-
DIMM8((sockets colored in black.) (see Section 2-3).
5. Check the position of the 115V/230V switch on the power supply.
