1	Hello everyone!!!
2
3	May be somebody can shed some light here... I'm building a server here with
4	4GB of RAM memory. The fact is, if I boot with mem=3072M everything goes as
5	fast as it should but I'm not using 1GB of memory. If I don't put the mem
6	option, Linux will see 4GB of memory available but it will be damn slow
7	(really).
8
9	To make Linux recognize 4 gigs of memory I had to activate HIGHMEM=64GB,
10	otherwise it only recognizes 3279MB (but it is fast).
11
12	My processor is a Intel Core 2 Duo E6320 (1.86Ghz). The motherboard is
13	Intel. I'm running Gentoo at 32bits mode and the kernel version is
14	2.6.20-gentoo-r8.
15
16	Any lights would be very appreciated.

18	Best regards,
