I suspect you've "proved" the RAM working - though to be totally sure you'd have to test each stick individually. If you did test each individual stick, and you're not running an Intel GPU [*1] then the problem should be the OS. I'd test each individual stick, ensure firmware is updated, check BIOS settings (memory remap) and also try a 3.2x kernel? [*1] AMD boards, large amounts of RAM, and Intel video have been problematic in the past. <snipped> Kind regards -- Iceweasel/Firefox/Chrome/Chromium/Iceape/IE extensions for finding answers to questions about Debian:- https://addons.mozilla.org/en-US/firefox/collections/Scott_Ferguson/debian/ -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
