Hi There,

I decided to upgrade my pc by adding a new kingston 2G DDR3 1033 kit .. I Bought it and placed it in the same slot color with the old one (kingston 2g DDR3 1033) .. when i turned on the pc it just gave a black screen without any beeps .. i removed the new one, it worked well .. i changed the clock freq. from the bios from AUTO To 667 and 553 and aslo they didnt work .. BUT when i changed the freq. to 400 .. the new kit worked well with the old one

This is my pc spes. without the new ram installed

With the 2 rams installed it Reads 400 MHZ

What should i do ?! Is the New kit is bad ?

Note the old one Model is KVR1333D3N9/2G
and the new one is KVR1333D3S8N9/2G
