Simple answer: There are no memory performance options in the BIOS. Unless it somehow automatically steps up, doubtful. From my numerous posts asking about memory upgrades in the past, not a single person chimed in with upgrading and seeing any difference. You could probably upgrade, but you'll run at whatever the BIOS was at with the previous ram/stock.
Someone would have to purchase better RAM, then use a utility to see what it's running at.
