Asus EEEPC 1015PD

[lucac3005]

I have an Eee PC 1015PD with a gig memory ram inside (mod. Asint ddr3 1 gb-1333 ssy3128m8-edjed) ... since it is possible to buy the 2 gig ram I purchased a bank of ram Kingston mod. kvr13s9s6 / 2 with the same characteristics as the original ... the problem is that it is not registered and the netbook does not even start ... I would like to know why and if a solution is possible ... thanks
