Addition RAM not recoginised by compiled kernel

[talha999]

Dear all

i just upgrade server RAM from 1 GB to 2 GB but it still showing old RAM setting in /proc/meminfo and aslo free -m command with my custom compiled kernel.

should i have to recompile kernel again ?

if yes what option should i selected so i will always recognise memory changes .

stock kernel is showing correct RAM

Thanks

Go back to make menuconfig and look at:

Processor type and features --->
(4GB) High Memory Support
HIGHMEM I/O support
MTRR (Memory Type Range Register) support

make sure you have that stuff enabled.
