Hello everyone!!!
May be somebody can shed some light here... I'm building a server here with
4GB of RAM memory. The fact is, if I boot with mem=3072M everything goes as
fast as it should but I'm not using 1GB of memory. If I don't put the mem
option, Linux will see 4GB of memory available but it will be damn slow
(really).
To make Linux recognize 4 gigs of memory I had to activate HIGHMEM=64GB,
otherwise it only recognizes 3279MB (but it is fast).
My processor is a Intel Core 2 Duo E6320 (1.86Ghz). The motherboard is
Intel. I'm running Gentoo at 32bits mode and the kernel version is
2.6.20-gentoo-r8.
Any lights would be very appreciated.
Best regards,
Daniel Colchete
