Pci Slots; Pci Retainer - HP xw9400 Service And Technical Reference Manual

The BIOS generates warnings/errors on invalid memory configurations.
●
If BIOS cannot obtain a valid memory configuration, it will halt the system with a diagnostics 2006
code for memory error (five beeps and blinks).
●
If memory node interleave is enabled but the memory installed on the two CPUs is not equal, BIOS
will report a warning during POST ("215-Cannot Interleave Unequal Memory Nodes"). The system
can still boot in this condition.
