Important Installation Considerations
Ensure the following when you are populating DIMMs.
• Only use DIMMs supplied by ClearCube.
• Ensure that DIMMs are the same speed and size.
• If you are using a processor that does not support Intel Graphic Technology, you
must install a DIMM in at least one of the DIMM 0 (blue) sockets for the blade to
boot.
Installing 2 DIMMs
1. Pull the tabs on either side of the memory socket away from the module to remove
the existing DIMMs.
2. Insert the new DIMMs in sockets 1 and 3 (the black socket of both channels). Align
the DIMM in the socket guides and firmly press down until the tabs snap into place.
