You actually check the box and allocate/click the up arrow until you reach the maximum memory in your system.
2.i go to the bios setup and i tried lowering the memory speed to 1333 mhz but it did not work too.
Are you sure your BIOS is up to date with the latest version with F6?

On that note can you please pass on your ram specs? They can be found off the package or the sticker on the side of the ram modules. Can you also please pass on your full systems specs? Have you tried reinstalling your OS? What was your prior ram installed in your system?
