Qimonda Dimms Return Manufacturer Mismatch Warning Message During Post - Sun Microsystems Fire X4100 Product Notes

Analysis
After the BIOS scans the network interface cards and SAS, the BIOS runs out of
address space for the option ROM and cannot scan the card. However, the card is
detected at the OS level and can still be used.
Workaround
To boot the system from an external storage device, connect the device to a
supported HBA controller installed in Slot 0.
Qimonda DIMMs Return Manufacturer
Mismatch Warning Message During POST
When the server boots and runs POST, the warning message,
NODE-n DIMMs Manufacturer Mismatch might be displayed for each DIMM.
Analysis
This warning message is seen with all supported Qimonda DIMMs and is caused by
the presence of a new JEDEC manufacturer's code. The new code is the result of
Infineon spinning off its DRAM unit into a new company named Qimonda. The
server BIOS has not yet been updated to recognize the new manufacturer's code.
Workaround
Note – Each DIMM-pair in the server must be identical—same manufacturer, size,
and speed.
Provided you know all DIMMs match, you can ignore this message.
