Welcome to the Forum

Please give us the model of the vaseky 4GB ram

First rule for not having memory problems is to have all sticks of same brand, same type, same speeds and timings (in other words, a matched pair).

You should have bought a a 4gb Samsung, exactly the same the one you already have and work with (4G in channel A+4G in channel B)
