** Description changed:

  After upgrading the memory from 8GB to 16GB I get randomly segmentation
  faults of the X server. Tests with either set of 8GB works fine and a
  memory test (memtest86+) ran for a week without any complaints. The
  machine is a Lenovo Thinkpad W510 with an nVidia Quadro FX880M running
  Maverick (10.10). I utilize the nVidia drivers that came with Ubuntu
  although they are marked as Beta?! Basically the same problem exists on
  my workstation that had from the go get 16GB but it runs Natty (11.04).
