Hi! What is the physical memory limit for 64-bit Linux? I read about 40 bit address bus for AMD Athlon X2 (1 TB) and 48 bit for Barcelona X4 (256 TB). Is 64-bit linux able to use that amount - provided that one would manage to build it into a machine? Or does it have a lower limit? Looking into the Google crystal ball gives unclear pictures... I tend to assume that Linux would handle it, but I am not sure. Ciao, -- Martin Steigerwald - team(ix) GmbH - http://www.teamix.de gpg: 19E3 8D42 896F D004 08AC A0CA 1E10 C593 0399 AE90
