Would it be possible
Sandy Bridge E are high end desktop/server CPUs that have a different socket (lga2011) and likely a different memory controller (4 channels instead of 2). A quick look at datasheet says nothing about maximum rank size. > to replace the 2620QM with an Ivy Bridge CPU? Afaik that should be possible since the CPU is socketed on that model but won't overcome your issue.
