memorytask-managerwindows 7
Laptop: Dell Inspiron 1525 Core-2-Duo
Pre-installed RAM: 2GB
Additional installed RAM: 2GB
OS: Windows 7
I have just installed extra 2 GB of RAM in Windows 7 and now it shows total 4 GB RAM.
After installing it when I look into Windows Task Manager it shows me 0 as Free Memory.
How it's showing 0 Free Memory?
Please, will anybody explain it to me?
How to understand it? Does it require any BIOS setting to be set?
Thanks and advance.
First of you will lose very much of your available memory with two graphic cards, that's 1GB of RAM lost right there plus the other devices.
There is a switch you can check in msconfig. Go to start, type msconfig and hit enter. Go to the boot tab, click advanced options. Check if the Max Memory option is enabled, if it is then disable it and reboot.
Edit:
The issue is with something called address space. On a 32-bit system you have 4GB of address space and all devices you need to use have to be mapped into the address space. Each device that gets mapped in will carve out a bit of the address space and render it unusable for the rest of the system.
The only way to get more than 2.5-3GB of usable memory in Windows is to install the 64-bit version. After that is installed it will look the same with only 2GB of memory usable. To get all available memory you need to go into BIOS and enable an option called memory remap.
The memory remap features moves all the mapped devices above the 4GB limit in the address space thus freeing up your address space for use by the system.
Make sure the Memory Remapping BIOS setting in the Advanced tab is enabled:

The important thing is to have available memory. not free.
in this post it explains what is it for
So don't worry about free memory because it can be used for system things or just reserved for programms
