Memory Errors

1. Make sure that all DIMM modules are properly and fully installed.
2. Determine if different speeds of DIMMs have been installed and verify that the
BIOS setup is confi gured for the fastest speed of RAM used. It is recom-
mended to use the same RAM speed for all DIMMs in the system.
3. Make sure that you are using the correct type of Registered, ECC DDRII 400
SDRAM (*recommended by the manufacturer.)
4. Check for bad DIMM modules or slots by swapping a single module between
two slots and noting the results.
5. Make sure that all memory modules are fully seated in their slots. As an in-
terleaved memory scheme is used, you must install two modules at a time,
beginning with DIMM #1A, then DIMM #1B, and so on (see Section 2-3).
6. Check the position of the 115V/230V switch on the power supply.
