Not showing full RAM

[mannu87]

I buyed HP Pavilion g6 1301tx laptop. It had 2 GB RAM. I upgraded from 2GB to 4GB. Now it has 4GB RAM. Then, I installed Backtrack 5 32 bit version on my laptop. But it is not showing full RAM. It is showing around 2.5GB memory only. What is the reason. How can it be solved?

It lies in the nature of 32bit operating systems that thet cannot detect a full 4 gigs of RAM, normally it stops at 3+- gigabyte

Since it's a new laptop try to download the 64 bit and see if that works. Do a usb boot and check the ram. If that works then just upgrade to 64. I have a hp dm4 with 4 gig i'm going to upgrade it to 8... Can't wait for that... lol...
