Have you ever pressed F1 to see how much memory is being recognized?

Also that CMOS battery may be weak or bad...about the size of a dime on your MBoard.

Part # CR 2032 available at any computer store.

Yes the new memory is recognized. As u told me might be Cmos battery. thanks all

I would also travel to crucial.com and enter your MBoard info and make sure you have not purchased the wrong RAM...
