Ram

[Guest sderf]

I have 4 gigs of Ram in my computer. When I open the systems floder It shows

me 3.12 gigs. Why is it not showing the 4 and why am I not able to use 4

gigs.

 

Any help would be great

Thanks

You must be running a 32 bit Windows version on your PC, correct?

What you are seeing is the amount of memory available to you after your

system has used a portion of the 4 gig address space (max that can be seen

by 32 bit Windows) for drivers, etc.

 

If you install a 64 bit OS, the drivers, etc. will be mapped to addresses

above your 4 gig, and you will have use of all 4 gig for applications, etc.

The fact that your hardware is 64 bit is immaterial. The limitation is in

your 32 bit OS.

Re: Ram

 

Check your BIOS - it should have an option to remap memory, it should be

enabled!

 

If it doesn't work, try flashing. Some BIOS's, even then, will not support

the full amount of RAM.

Re: Ram

 

Tony is correct. You need to be running the latest version of your BIOS, and

you need to enable the memory re-mapping in it. This is off by default

(since it would cause a problem for a 32-bit OS) and it isn't an available

option on all current BIOSs, though most seem to have finally caught up with

it.

 

The problem is that other hardware in your computer needs memory address

space. Since 32-bit Windows is limited to 4 GB of flat memory address space,

those hardware addresses need to be in that 4GB, and they block your seeing

all of your RAM. Since you're running XP x64, the BIOS can do some memory

re-mapping and this allows you to see more of your memory.
