I just want to raise some concerns about this approach on boards with DIMM 
modules. Here it will be hard to determine if a new DIMM module is installed. 
Even a module from the same manufacturer and type (size, width etc, all the 
same) will need a new autocalibration. This is probably hard to detect.

Just my $0.02.

Best regards,
Stefan
