Windows XP 32bit not showing full RAM size
I have Lenovo R60 laptop (9458-A18) with 1GB RAM, 80GB 5400 RPM HDD and windows XP Professional with SP3.Recently i have update 4GB RAM. In BIOS it showing 4GB RAM, but in XP system properties it showing only 3GB RAM installed. My laptop have 945GM chipset it support upto 4GB RAM and windows XP 32bit will support upto 4GB RAM. But it displaying 3GB only. Is there any solution to rectify this problem. one more question currently i am having 80GB HDD with 5400RPM. my question is i can update my HDD with 320GB @ 7200RPM?

As has been said what you are seeing is NORMAL and to be expected
A 32 bit OS can 'see' 4Gb of memory but some of this address space is used for system functions such as IO etc. As a result the most memory that can be used is around the 3Gb mark.

Hi,
It's not correct to say the 945GM does not support more than 3GB system RAM even when a 64 bit operating system is installed?
I am typing this on an ACER 8935G desktop replacement with 8 GB DDR3 RAM - it uses a 945GM chipset.

hi
yes 945GM chipset. can support until 8 gb but Windows XP Professional 32-bit is limited to 4GB of address space. If you have 4GB of RAM installed, it will not show 4GB within Windows even if you install it in acer

you have to install os 64 bits in acer to benefit of 8gb of ram
Check video settings in BIOS and configure it- you'll get change in numbers.
