Thanks for pinpointing the Intel XTU thing BlueSwordM, undervolting is something I once did (pretty manually with a laptop software only available for 32-bit operating systems) in a very old Core2 Duo laptop running XP which is now going to be recycled.

Concerning the memory constrained thing, are you going to tell me 4GB is seriously enough? As far as I know just a single internet browser with a bunch of tabs may need a few GBs, doesn't it?
