Memory Errors
Make sure that the DIMM modules are properly and fully installed. Check if 1.
different speeds of DIMMs have been installed and make sure that the BIOS
setup is confi gured for the fastest speed of RAM used. It is recommended that
you use the same RAM speed for all DIMMs in the system.
Make sure that you are using the correct type of 1.5V/1.8V DDR2 FBD (Fully 2.
Buffered) ECC 800/667/533 SDRAM (recommended by the manufacturer.)
Check for bad DIMM modules or slots by swapping a single module between
four slots and noting the results. Make sure that all memory modules are fully
seated in their slots. To install memory modules, begin with Bank 1, then Bank
2, and so on (see Page 2-6).
