Can Fedora 14 (32-bit) Utilize 8gb of RAM?

Hello,

I'm running Fedora 14, 32-bit edition.

My Motherboard (ASUS M2NPV-VM) says it can handle up to 8gb of RAM.

If I install 8gb of RAM, will my OS be able to utilize all 8gb or still just 4gb?

Basically, is it a waste of money to have more than 4gb of RAM on a 32-bit Linux install?

Thanks,
Jason

On the one hand, Linux kernel should handle it.  I've had servers in my data center with 32gb on 32bit RHEL 4 because of an application need.

On the other hand, you will face some application issues because of the 4gb user space limitation.  Unless you have a specific need, I'd use x64 version.

To use all of your memory you can install a PAE (Physical Address Extension) enabled kernel.
(more details: http://en.wikipedia.org/wiki/Physical_Address_Extension)

+ can use memory over 4 GB on 32 bit Linux
- applications are still limited to 32 bit address space: no single process can use more than 3GB (on most modern kernels) or 2GB (on older ones)
- a small performance overhead for the additional mapping layer in memory management

If you have one large application requiring >3GB you are out of luck with PAE - use 64bit Linux
If you have several applications requiring less than 3GB PAE is your friend
