Hi all, are the athlon 64 memory controller registers description publicly available ? I have a Dell Inspiron 1501 (Athlon 64 Turion X2, ATI RS480 NB, ATI SB600) with 1GB of RAM. Dell specifies that the 1501 can have "up to 2GB of RAM". Can anybody guess whether it would boot with 4GB of memory, disabling the upper 2GB, and whether I'd be able to re-enable the upper 2GB (preferably mapped above the 4GB limit: I don't mind, I'm running in 64bit mode and I'd not lose memory in the "3GB hole"). Thank you, Loïc Grenié
