Memory Errors
Make sure the DIMM modules are properly and fully installed. Check if 1.
DIMMs of different speeds or types have been installed. Also make sure 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. 2.
Make sure you are using the correct type of DDR2 Unbuffered ECC/Non-
ECC 800/667 MHz SDRAM (recommended by the manufacturer.)
Check for bad DIMM modules or slots by swapping a single module between 3.
four slots and noting the results. 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 2-4). Check the position of the 115V/230V switch on the power
supply.
