Memory Errors
1. Make sure the DIMM modules are properly and fully installed.
2. Determine if DIMMs of different speeds or types have been installed and verify
that the BIOS setup is confi gured 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 DDR2 Fully Buffered (FBD) ECC
533/667 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.
6. Check the position of the 115V/230V switch on the power supply.
