4GB RAM not visible to OS

[snayak]

Dear All,

I purchased a Lenovo G570 (Model Name: 20079).

It has Core i3 2350M and 4GB RAM.

I installed windows xp(32-bit).

When I checked the task manager/properties of my computer; it shows only 3GB of RAM.

Also I installed puppy linux(32-bit), and checked top; it shows 3GB of total memory.

What shall I do, so that 4GB will be visible to OS?

Sincerely,

Srinivas Nayak

hi snayak

i'm not sure about linux but windows xp doesn't support 4 gb ram at maximum. you can install it but the system will only use 3 gb of. you will need to install at least 64 bit operation system.

hope this helps.

Same in Linux.
32 bit = 3GB

Use Operating system with 64Bit not 32Bit .
