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 on page 69). 2. Gently push outward on the socket levers. 3. Lower the DIMM straight down and be sure the socket levers secure the module into place. 4. Reinstall the memory fan (Memory fan on page 69). NOTE: Ensure that all cables are clear of the fan housing when lowering the memory fan.
