Your dmesg does suggest that the kernel knows 4GB, but HIGHMEM4G is probably set to 'no'.
in that case, according to the kernel documentation: "If you are compiling a kernel which will never run on a machine with more than 1 Gigabyte total physical RAM, answer "off" here (default choice and suitable for most users). This will result in a "3GB/1GB" split: 3GB are mapped so that each process sees a 3GB virtual memory space and the remaining part of the 4GB virtual memory space is used by the kernel to permanently map as much physical memory as possible." Using an appropriate kernel should solve your problem. On Sun, 21 Oct 2007, pgega wrote:

Andrei, do not hurt me , but I am not too familiar with k7 ? Is it just option of kernel ,like 2.6.23.1-k7 or more like system architecture x86 , am64 etc?. I use AMD 64 Athlon X2 is K7 for me ? I tried swaping all of them in any possible order, none of sticks is broken. Kind regards, Pawel Gega -- To UNSUBSCRIBE, email to debian-user-REQUEST@lists.debian.org with a subject of "unsubscribe".
