With a x32 in DIMM Slot 3, a x8 is not supported in either DIMM Slots 1 or 2. All other
combinations of DIMM Modules (with the exception of the x4's) are supported. If an
unsupported configuration is found, the solution is to simply move the DIMM Modules
into a supported configuration. Table E-2 shows which configurations are or are not.
ROM Error Message
If the ROM encounters a x4 DIMM Module or any of the unsupported x8/x32
combinations in the system during POST, the ROM will issue a "213 – Incompatible
DIMM in Slot x,x,x" (where x = the slot number(s) of the incompatible DIMM(s)) and
halt the processor (the system will not boot). If this error occurs, the incompatibility must
be fixed before the ROM will allow the system to boot.
