utilize 4gb of ram

cynick · 04-20-2006, 10:36 AM

if I get 4gb of ram, what is the best way to utilize it on my suse 10?

Is it possible to have 2gb for a dynamic virtual disk to load stuff like firefox and etc, but still be able to reclaim this memory upon high memory demand (like vmware)?

it could be very well a waste of money, so accepting any suggestions.

at the moment I've got pc 133 750mb, athlon xp 1800+ and thinking to updgrade to some of those dual core crap

this is, in effect, what the linux kernel already does for you. If you load an app it is retained in memory. However, if that memory is needed elsewhere, then so be it.

i think 4gb could be a bit excesive. with 2gb you could run a VMWare session easily. DEpending on what you are doing i guess....

also you have to change a parameter in the kernel to get more than 900mb of ram. if that's the case the you will probably have to get the source code for your kernel, presuming it is a modified SuSE one and not a stock kernel.....

The following it is true to Fedora, SuSE and RHEL.

In fact, check the config file which comes with your kernel. It is /boot/config*.
It has all settings that were used to compile the kernel.
At some point you will see:

Code:

CONFIG_HIGHMEM4G=y
# CONFIG_HIGHMEM64G is not set

this shows the kernel has support to 4G but not to 64G.
