The BIOS generates warnings/errors on invalid memory configurations.
● If there is no way to obtain a valid memory configuration by disabling some of the plugged-in
memory, the BIOS will halt with a diagnostics 2006 code for memory error (five beeps/blinks).
●
If the BIOS can find a valid memory configuration by disabling some of the plugged-in memory, it
will do so and will report a warning during POST (“215-mismatched memory”). The system can still
be booted in this condition.
Installing a DIMM
1. Disconnect power from the system ( Predisassembly procedures on page 57 ), remove the side
access panel ( Side access panel on page 63 ), and remove memory fan ( Memory fan
