Is there anything I can do to use full 4 GB of RAM instead of 3.24 GB

Any one full utilizing 4 GB?


Thanks

Your notebook comes with an Intel graphics chip that does not have
dedicated video ram. That means that the system is using some of your
system ram as Video ram, and that memory will never be available to the
Operating system.

You should be able to reduced the amount of reserved memory in your
BIOS, but you always need some.

My dell 640m's bios dedicated 8MB to video which is not changeable
(strange) . In memory section, it says Memory install = 4096 and
Memory available = 3312.
This means I will not be able to use full 4 GB in this bios?

I am not really knowledgeable about your BIOS. However, the 8MB
mentioned is almost certainly the prehistoric standard memory IO range.
This would only change if you had two video cards running. The shared
memory area you are looking for is much larger, like 64MB to 512MB or
so. It must be there somewhere in your BIOS. This much larger memory
range is used shared between CPU and Video CPU, such that one don't have
to transfer the long and slooow way through IO-port/8MB road.

I double checked it. I didn't see where I can change video memory.
And 8MB has been allocated. Does my BIOS has a problem?
