Hartmann" To: freebsd-stable@freebsd.org Cc: freebsd-hardware@freebsd.org Subject: max. amount of physical memory in FBSD 4.1? Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Dear Sirs. Every step done under Linux is well documented by the press, especially here in Germany! When Microsoft found a bug in AMD's Athlon CPUs which causes Win2k to crash, the 4GB physical memory limit came into play again. Some discussions were made about PAE addressing modell and so on and although the discussion started on a M$ <-> AMD problem, the migration towards Linux's memory modell was done smoothly. Well, we now know, Linux has recently a 4GB physical memory limitation due its PAE address space model. And what is about FreeBSD 4.1? We use now TYAN's Thunder 2500 maonboard which is capable to hold two CPUs and get equipted with max. 8GB main memory. This is a nice option because we plan to solve some memory intensive environtmental research calculations. So, my question seems to be stupid for those who understand reading kernel code, but for me, a kind of "normalo", please tell me: how much memory and how many CPUs is FreeBSD 4.1.1-STABLE capable to work with in a stable fashion? Many thanks, Gruss O.
